"#NNN" occurrences refer to bug tracker issues at: https://github.com/giampaolo/psutil/issues PLATFORMS ========= - #355: Android (with patch) - #82: Cygwin (PR at #998) - #276: GNU/Hurd - #693: Windows Nano - DragonFlyBSD - HP-UX FEATURES ======== - #371: sensors_temperatures() at least for OSX. - #669: Windows / net_if_addrs(): return broadcast addr. - #550: CPU info (frequency, architecture, threads per core, cores per socket, sockets, ...) - #772: extended net_io_counters() metrics. - #900: wheels for OSX and Linux. - #922: extended net_io_stats() info. - #914: extended platform specific process info. - #898: wifi stats - #893: (BSD) process environ - #809: (BSD) per-process resource limits (rlimit()). - (UNIX) process root (different from cwd) - #782: (UNIX) process num of signals received. - (Linux) locked files via /proc/locks: https://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-proc-locks.html - #269: NIC rx/tx queue. This should probably go into net_if_stats(). Figure out on what platforms this is supported: Linux: yes Others: ? - Process.threads(): thread names; patch for OSX available at: https://code.google.com/p/plcrashreporter/issues/detail?id=65 Sample code: https://github.com/janmojzis/pstree/blob/master/proc_kvm.c - Asynchronous psutil.Popen (see http://bugs.python.org/issue1191964) - (Windows) fall back on using WMIC for Process methods returning AccessDenied - #613: thread names. - #604: emulate os.getloadavg() on Windows - scripts/taskmgr-gui.py (using tk). - system-wide number of open file descriptors: - https://jira.hyperic.com/browse/SIGAR-30 - Number of system threads. - Windows: http://msdn.microsoft.com/en-us/library/windows/desktop/ms684824(v=vs.85).aspx - Doc / wiki which compares similarities between UNIX cli tools and psutil. Example: ``` df -a -> psutil.disk_partitions lsof -> psutil.Process.open_files() and psutil.Process.open_connections() killall-> (actual script) tty -> psutil.Process.terminal() who -> psutil.users() ``` - psutil.proc_tree() something which obtains a {pid:ppid, ...} dict for all running processes in one shot. This can be factored out from Process.children() and exposed as a first class function. PROS: on Windows we can take advantage of _psutil_windows.ppid_map() which is faster than iterating over all pids and calling ppid(). CONS: scripts/pstree.py shows this can be easily done in the user code so maybe it's not worth the addition. - advanced cmdline interface exposing the whole API and providing different kind of outputs (e.g. pprinted, colorized, json). - [Linux]: process cgroups (http://en.wikipedia.org/wiki/Cgroups). They look similar to prlimit() in terms of functionality but uglier (they should allow limiting per-process network IO resources though, which is great). Needs further reading. - Python 3.3. exposed different sched.h functions: http://docs.python.org/dev/whatsnew/3.3.html#os http://bugs.python.org/issue12655 http://docs.python.org/dev/library/os.html#interface-to-the-scheduler It might be worth to take a look and figure out whether we can include some of those in psutil. Also, we can probably reimplement wait_pid() on POSIX which is currently implemented as a busy-loop. - os.times() provides 'elapsed' times (cpu_times() might). - ...also guest_time and cguest_time on Linux. - Enrich exception classes hierarchy on Python >= 3.3 / post PEP-3151 so that: - NoSuchProcess inherits from ProcessLookupError - AccessDenied inherits from PermissionError - TimeoutExpired inherits from TimeoutError (debatable) See: http://docs.python.org/3/library/exceptions.html#os-exceptions - Process.threads() might grow an extra "id" parameter so that it can be used as such: ``` >>> p = psutil.Process(os.getpid()) >>> p.threads(id=psutil.current_thread_id()) thread(id=2539, user_time=0.03, system_time=0.02) >>> ``` Note: this leads to questions such as "should we have a custom NoSuchThread exception? Also see issue #418. Note #2: this would work with os.getpid() only. psutil.current_thread_id() might be desirable as per issue #418 though. - should psutil.TimeoutExpired exception have a 'msg' kwarg similar to NoSuchProcess and AccessDenied? Not that we need it, but currently we cannot raise a TimeoutExpired exception with a specific error string. - process_iter() might grow an "attrs" parameter similar to Process.as_dict() invoke the necessary methods and include the results into a "cache" attribute attached to the returned Process instances so that one can avoid catching NSP and AccessDenied: for p in process_iter(attrs=['cpu_percent']): print(p.cache['cpu_percent']) This also leads questions as whether we should introduce a sorting order. - round Process.memory_percent() result? - #550: number of threads per core. BUGFIXES ======== - #600: windows / open_files(): support network file handles.

Additional help also came from the following sources: https://github.com/kohsuke/winp and http://wj32.org/wp/2009/01/24/howto-get-the-command-line-of-processes/ http://stackoverflow.com/a/14012919 http://www.drdobbs.com/embracing-64-bit-windows/184401966 */ static _NtQueryInformationProcess NtQueryInformationProcess = NULL; #ifndef _WIN64 static _NtQueryInformationProcess NtWow64QueryInformationProcess64 = NULL; static _NtWow64ReadVirtualMemory64 NtWow64ReadVirtualMemory64 = NULL; #endif HANDLE hProcess = NULL; LPCVOID src; SIZE_T size; WCHAR *buffer = NULL; #ifdef _WIN64 LPVOID ppeb32 = NULL; #else PVOID64 src64; BOOL weAreWow64; BOOL theyAreWow64; #endif hProcess = psutil_handle_from_pid(pid); if (hProcess == NULL) return -1; if (NtQueryInformationProcess == NULL) { NtQueryInformationProcess = (_NtQueryInformationProcess)GetProcAddress( GetModuleHandleA("ntdll.dll"), "NtQueryInformationProcess"); } #ifdef _WIN64 /* 64 bit case.

Quick links ----------- - `Home page `__ - `Install `_ - `Blog `__ - `Forum `__ - `Download `__ - `Development guide `_ - `What's new `__ About ----- psutil (python system and process utilities) is a cross-platform library for retrieving information on running **processes** and **system utilization** (CPU, memory, disks, network, sensors) in **Python**. It is useful mainly for **system monitoring**, **profiling**, **limiting process resources** and the **management of running processes**. It implements many functionalities offered by UNIX command line tools such as: *ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap*. psutil currently supports the following platforms: - **Linux** - **Windows** - **OSX**, - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** ...both **32-bit** and **64-bit** architectures, with Python versions from **2.6 to 3.6** (users of Python 2.4 and 2.5 may use `2.1.3 `__ version). `PyPy `__ is also known to work. The psutil documentation you're reading is distributed as a single HTML page. Install ------- The easiest way to install psutil is via ``pip``:: pip install psutil On UNIX this requires a C compiler (e.g. gcc) installed. On Windows pip will automatically retrieve a pre-compiled wheel version from `PYPI repository `__. Alternatively, see more detailed `install `_ instructions. System related functions ======================== CPU --- .. function:: cpu_times(percpu=False) Return system CPU times as a named tuple. Every attribute represents the seconds the CPU has spent in the given mode. The attributes availability varies depending on the platform: - **user**: time spent by normal processes executing in user mode; on Linux this also includes **guest** time - **system**: time spent by processes executing in kernel mode - **idle**: time spent doing nothing Platform-specific fields: - **nice** *(UNIX)*: time spent by niced (prioritized) processes executing in user mode; on Linux this also includes **guest_nice** time - **iowait** *(Linux)*: time spent waiting for I/O to complete - **irq** *(Linux, BSD)*: time spent for servicing hardware interrupts - **softirq** *(Linux)*: time spent for servicing software interrupts - **steal** *(Linux 2.6.11+)*: time spent by other operating systems running in a virtualized environment - **guest** *(Linux 2.6.24+)*: time spent running a virtual CPU for guest operating systems under the control of the Linux kernel - **guest_nice** *(Linux 3.2.0+)*: time spent running a niced guest (virtual CPU for guest operating systems under the control of the Linux kernel) - **interrupt** *(Windows)*: time spent for servicing hardware interrupts ( similar to "irq" on UNIX) - **dpc** *(Windows)*: time spent servicing deferred procedure calls (DPCs); DPCs are interrupts that run at a lower priority than standard interrupts. When *percpu* is ``True`` return a list of named tuples for each logical CPU on the system. First element of the list refers to first CPU, second element to second CPU and so on. The order of the list is consistent across calls. Example output on Linux: >>> import psutil >>> psutil.cpu_times() scputimes(user=17411.7, nice=77.99, system=3797.02, idle=51266.57, iowait=732.58, irq=0.01, softirq=142.43, steal=0.0, guest=0.0, guest_nice=0.0) .. versionchanged:: 4.1.0 added *interrupt* and *dpc* fields on Windows. .. function:: cpu_percent(interval=None, percpu=False) Return a float representing the current system-wide CPU utilization as a percentage. When *interval* is > ``0.0`` compares system CPU times elapsed before and after the interval (blocking). When *interval* is ``0.0`` or ``None`` compares system CPU times elapsed since last call or module import, returning immediately. That means the first time this is called it will return a meaningless ``0.0`` value which you are supposed to ignore. In this case it is recommended for accuracy that this function be called with at least ``0.1`` seconds between calls. When *percpu* is ``True`` returns a list of floats representing the utilization as a percentage for each CPU. First element of the list refers to first CPU, second element to second CPU and so on. The order of the list is consistent across calls. >>> import psutil >>> # blocking >>> psutil.cpu_percent(interval=1) 2.0 >>> # non-blocking (percentage since last call) >>> psutil.cpu_percent(interval=None) 2.9 >>> # blocking, per-cpu >>> psutil.cpu_percent(interval=1, percpu=True) [2.0, 1.0] >>> .. warning:: the first time this function is called with *interval* = ``0.0`` or ``None`` it will return a meaningless ``0.0`` value which you are supposed to ignore. .. function:: cpu_times_percent(interval=None, percpu=False) Same as :func:`cpu_percent()` but provides utilization percentages for each specific CPU time as is returned by :func:`psutil.cpu_times(percpu=True)`. *interval* and *percpu* arguments have the same meaning as in :func:`cpu_percent()`. On Linux "guest" and "guest_nice" percentages are not accounted in "user" and "user_nice" percentages. .. warning:: the first time this function is called with *interval* = ``0.0`` or ``None`` it will return a meaningless ``0.0`` value which you are supposed to ignore. .. versionchanged:: 4.1.0 two new *interrupt* and *dpc* fields are returned on Windows. .. function:: cpu_count(logical=True) Return the number of logical CPUs in the system (same as `os.cpu_count() `__ in Python 3.4) or ``None`` if undetermined. This number may not be equivalent to the number of CPUs the current process can actually use in case process CPU affinity has been changed or Linux cgroups are being used. The number of usable CPUs can be obtained with ``len(psutil.Process().cpu_affinity())``. If *logical* is ``False`` return the number of physical cores only (hyper thread CPUs are excluded). On OpenBSD and NetBSD ``psutil.cpu_count(logical=False)`` always return ``None``. Example on a system having 2 physical hyper-thread CPU cores: >>> import psutil >>> psutil.cpu_count() 4 >>> psutil.cpu_count(logical=False) 2 Example returning the number of CPUs usable by the current process: >>> len(psutil.Process().cpu_affinity()) 1 .. function:: cpu_stats() Return various CPU statistics as a named tuple: - **ctx_switches**: number of context switches (voluntary + involuntary) since boot. - **interrupts**: number of interrupts since boot. - **soft_interrupts**: number of software interrupts since boot. Always set to ``0`` on Windows and SunOS. - **syscalls**: number of system calls since boot. Always set to ``0`` on Linux. Example (Linux): .. code-block:: python >>> import psutil >>> psutil.cpu_stats() scpustats(ctx_switches=20455687, interrupts=6598984, soft_interrupts=2134212, syscalls=0) .. versionadded:: 4.1.0 .. function:: cpu_freq(percpu=False) Return CPU frequency as a nameduple including *current*, *min* and *max* frequencies expressed in Mhz. On Linux *current* frequency reports the real-time value, on all other platforms it represents the nominal "fixed" value. If *percpu* is ``True`` and the system supports per-cpu frequency retrieval (Linux only) a list of frequencies is returned for each CPU, if not, a list with a single element is returned. If *min* and *max* cannot be determined they are set to ``0``. Example (Linux): .. code-block:: python >>> import psutil >>> psutil.cpu_freq() scpufreq(current=931.42925, min=800.0, max=3500.0) >>> psutil.cpu_freq(percpu=True) [scpufreq(current=2394.945, min=800.0, max=3500.0), scpufreq(current=2236.812, min=800.0, max=3500.0), scpufreq(current=1703.609, min=800.0, max=3500.0), scpufreq(current=1754.289, min=800.0, max=3500.0)] Availability: Linux, OSX, Windows .. versionadded:: 5.1.0 Memory ------ .. function:: virtual_memory() Return statistics about system memory usage as a named tuple including the following fields, expressed in bytes. Main metrics: - **total**: total physical memory. - **available**: the memory that can be given instantly to processes without the system going into swap. This is calculated by summing different memory values depending on the platform and it is supposed to be used to monitor actual memory usage in a cross platform fashion. Other metrics: - **used**: memory used, calculated differently depending on the platform and designed for informational purposes only. **total - free** does not necessarily match **used**. - **free**: memory not being used at all (zeroed) that is readily available; note that this doesn't reflect the actual memory available (use **available** instead). **total - used** does not necessarily match **free**. - **active** *(UNIX)*: memory currently in use or very recently used, and so it is in RAM. - **inactive** *(UNIX)*: memory that is marked as not used. - **buffers** *(Linux, BSD)*: cache for things like file system metadata. - **cached** *(Linux, BSD)*: cache for various things. - **shared** *(Linux, BSD)*: memory that may be simultaneously accessed by multiple processes. - **wired** *(BSD, OSX)*: memory that is marked to always stay in RAM. It is never moved to disk. The sum of **used** and **available** does not necessarily equal **total**. On Windows **available** and **free** are the same. See `meminfo.py `__ script providing an example on how to convert bytes in a human readable form. .. note:: if you just want to know how much physical memory is left in a cross platform fashion simply rely on the **available** field. >>> import psutil >>> mem = psutil.virtual_memory() >>> mem svmem(total=10367352832, available=6472179712, percent=37.6, used=8186245120, free=2181107712, active=4748992512, inactive=2758115328, buffers=790724608, cached=3500347392, shared=787554304) >>> >>> THRESHOLD = 100 * 1024 * 1024 # 100MB >>> if mem.available <= THRESHOLD: ... print("warning") ... >>> .. versionchanged:: 4.2.0 added *shared* metrics on Linux. .. versionchanged:: 4.4.0 *available* and *used* values on Linux are more precise and match "free" cmdline utility. .. function:: swap_memory() Return system swap memory statistics as a named tuple including the following fields: * **total**: total swap memory in bytes * **used**: used swap memory in bytes * **free**: free swap memory in bytes * **percent**: the percentage usage calculated as ``(total - available) / total * 100`` * **sin**: the number of bytes the system has swapped in from disk (cumulative) * **sout**: the number of bytes the system has swapped out from disk (cumulative) **sin** and **sout** on Windows are always set to ``0``. See `meminfo.py `__ script providing an example on how to convert bytes in a human readable form. >>> import psutil >>> psutil.swap_memory() sswap(total=2097147904L, used=886620160L, free=1210527744L, percent=42.3, sin=1050411008, sout=1906720768) .. versionchanged:: 5.2.3 on Linux this function relies on /proc fs instead of sysinfo() syscall so that it can be used in conjunction with :const:`psutil.PROCFS_PATH` in order to retrieve memory info about Linux containers such as Docker and Heroku. Disks ----- .. function:: disk_partitions(all=False) Return all mounted disk partitions as a list of named tuples including device, mount point and filesystem type, similarly to "df" command on UNIX. If *all* parameter is ``False`` it tries to distinguish and return physical devices only (e.g. hard disks, cd-rom drives, USB keys) and ignore all others (e.g. memory partitions such as `/dev/shm `__). Note that this may not be fully reliable on all systems (e.g. on BSD this parameter is ignored). Named tuple's **fstype** field is a string which varies depending on the platform. On Linux it can be one of the values found in /proc/filesystems (e.g. ``'ext3'`` for an ext3 hard drive o ``'iso9660'`` for the CD-ROM drive). On Windows it is determined via `GetDriveType `__ and can be either ``"removable"``, ``"fixed"``, ``"remote"``, ``"cdrom"``, ``"unmounted"`` or ``"ramdisk"``. On OSX and BSD it is retrieved via `getfsstat(2) `__. See `disk_usage.py `__ script providing an example usage. >>> import psutil >>> psutil.disk_partitions() [sdiskpart(device='/dev/sda3', mountpoint='/', fstype='ext4', opts='rw,errors=remount-ro'), sdiskpart(device='/dev/sda7', mountpoint='/home', fstype='ext4', opts='rw')] .. function:: disk_usage(path) Return disk usage statistics about the partition which contains the given *path* as a named tuple including **total**, **used** and **free** space expressed in bytes, plus the **percentage** usage. `OSError `__ is raised if *path* does not exist. Starting from `Python 3.3 `__ this is also available as `shutil.disk_usage() `__. See `disk_usage.py `__ script providing an example usage. >>> import psutil >>> psutil.disk_usage('/') sdiskusage(total=21378641920, used=4809781248, free=15482871808, percent=22.5) .. note:: UNIX usually reserves 5% of the total disk space for the root user. *total* and *used* fields on UNIX refer to the overall total and used space, whereas *free* represents the space available for the **user** and *percent* represents the **user** utilization (see `source code `__). That is why *percent* value may look 5% bigger than what you would expect it to be. Also note that both 4 values match "df" cmdline utility. .. versionchanged:: 4.3.0 *percent* value takes root reserved space into account. .. function:: disk_io_counters(perdisk=False, nowrap=True) Return system-wide disk I/O statistics as a named tuple including the following fields: - **read_count**: number of reads - **write_count**: number of writes - **read_bytes**: number of bytes read - **write_bytes**: number of bytes written Platform-specific fields: - **read_time**: (all except *NetBSD* and *OpenBSD*) time spent reading from disk (in milliseconds) - **write_time**: (all except *NetBSD* and *OpenBSD*) time spent writing to disk (in milliseconds) - **busy_time**: (*Linux*, *FreeBSD*) time spent doing actual I/Os (in milliseconds) - **read_merged_count** (*Linux*): number of merged reads (see `iostat doc `__) - **write_merged_count** (*Linux*): number of merged writes (see `iostats doc `__) If *perdisk* is ``True`` return the same information for every physical disk installed on the system as a dictionary with partition names as the keys and the named tuple described above as the values.

Every named tuple provides 7 attributes: - **fd**: the socket file descriptor. If the connection refers to the current process this may be passed to `socket.fromfd() `__ to obtain a usable socket object. On Windows and SunOS this is always set to ``-1``. - **family**: the address family, either `AF_INET `__, `AF_INET6 `__ or `AF_UNIX `__. - **type**: the address type, either `SOCK_STREAM `__ or `SOCK_DGRAM `__. - **laddr**: the local address as a ``(ip, port)`` named tuple or a ``path`` in case of AF_UNIX sockets. For UNIX sockets see notes below. - **raddr**: the remote address as a ``(ip, port)`` named tuple or an absolute ``path`` in case of UNIX sockets. When the remote endpoint is not connected you'll get an empty tuple (AF_INET*) or ``""`` (AF_UNIX). For UNIX sockets see notes below. - **status**: represents the status of a TCP connection. The return value is one of the :data:`psutil.CONN_* ` constants (a string). For UDP and UNIX sockets this is always going to be :const:`psutil.CONN_NONE`. - **pid**: the PID of the process which opened the socket, if retrievable, else ``None``. On some platforms (e.g. Linux) the availability of this field changes depending on process privileges (root is needed). The *kind* parameter is a string which filters for connections matching the following criteria: .. table:: +----------------+-----------------------------------------------------+ | **Kind value** | **Connections using** | +================+=====================================================+ | ``"inet"`` | IPv4 and IPv6 | +----------------+-----------------------------------------------------+ | ``"inet4"`` | IPv4 | +----------------+-----------------------------------------------------+ | ``"inet6"`` | IPv6 | +----------------+-----------------------------------------------------+ | ``"tcp"`` | TCP | +----------------+-----------------------------------------------------+ | ``"tcp4"`` | TCP over IPv4 | +----------------+-----------------------------------------------------+ | ``"tcp6"`` | TCP over IPv6 | +----------------+-----------------------------------------------------+ | ``"udp"`` | UDP | +----------------+-----------------------------------------------------+ | ``"udp4"`` | UDP over IPv4 | +----------------+-----------------------------------------------------+ | ``"udp6"`` | UDP over IPv6 | +----------------+-----------------------------------------------------+ | ``"unix"`` | UNIX socket (both UDP and TCP protocols) | +----------------+-----------------------------------------------------+ | ``"all"`` | the sum of all the possible families and protocols | +----------------+-----------------------------------------------------+ On OSX and AIX this function requires root privileges. To get per-process connections use :meth:`Process.connections`. Also, see `netstat.py sample script `__.

This is a limitation of the OS and ``lsof`` does the same. .. note:: (Solaris) UNIX sockets are not supported. .. note:: (Linux, FreeBSD) "raddr" field for UNIX sockets is always set to "". This is a limitation of the OS. .. note:: (OpenBSD) "laddr" and "raddr" fields for UNIX sockets are always set to "".

Each named tuple includes 5 fields: - **family**: the address family, either `AF_INET `__, `AF_INET6 `__ or :const:`psutil.AF_LINK`, which refers to a MAC address. - **address**: the primary NIC address (always set). - **netmask**: the netmask address (may be ``None``). - **broadcast**: the broadcast address (may be ``None``). - **ptp**: stands for "point to point"; it's the destination address on a point to point interface (typically a VPN). *broadcast* and *ptp* are mutually exclusive. May be ``None``. Example:: >>> import psutil >>> psutil.net_if_addrs() {'lo': [snic(family=, address='127.0.0.1', netmask='255.0.0.0', broadcast='127.0.0.1', ptp=None), snic(family=, address='::1', netmask='ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff', broadcast=None, ptp=None), snic(family=, address='00:00:00:00:00:00', netmask=None, broadcast='00:00:00:00:00:00', ptp=None)], 'wlan0': [snic(family=, address='192.168.1.3', netmask='255.255.255.0', broadcast='192.168.1.255', ptp=None), snic(family=, address='fe80::c685:8ff:fe45:641%wlan0', netmask='ffff:ffff:ffff:ffff::', broadcast=None, ptp=None), snic(family=, address='c4:85:08:45:06:41', netmask=None, broadcast='ff:ff:ff:ff:ff:ff', ptp=None)]} >>> See also `nettop.py `__ and `ifconfig.py `__ for an example application. .. note:: if you're interested in others families (e.g. AF_BLUETOOTH) you can use the more powerful `netifaces `__ extension. .. note:: you can have more than one address of the same family associated with each interface (that's why dict values are lists). .. note:: *broadcast* and *ptp* are not supported on Windows and are always ``None``. .. versionadded:: 3.0.0 .. versionchanged:: 3.2.0 *ptp* field was added. .. versionchanged:: 4.4.0 added support for *netmask* field on Windows which is no longer ``None``. .. function:: net_if_stats() Return information about each NIC (network interface card) installed on the system as a dictionary whose keys are the NIC names and value is a named tuple with the following fields: - **isup**: a bool indicating whether the NIC is up and running. - **duplex**: the duplex communication type; it can be either :const:`NIC_DUPLEX_FULL`, :const:`NIC_DUPLEX_HALF` or :const:`NIC_DUPLEX_UNKNOWN`. - **speed**: the NIC speed expressed in mega bits (MB), if it can't be determined (e.g. 'localhost') it will be set to ``0``. - **mtu**: NIC's maximum transmission unit expressed in bytes. Example: >>> import psutil >>> psutil.net_if_stats() {'eth0': snicstats(isup=True, duplex=, speed=100, mtu=1500), 'lo': snicstats(isup=True, duplex=, speed=0, mtu=65536)} Also see `nettop.py `__ and `ifconfig.py `__ for an example application. .. versionadded:: 3.0.0 Sensors ------- .. function:: sensors_temperatures(fahrenheit=False) Return hardware temperatures. Each entry is a named tuple representing a certain hardware temperature sensor (it may be a CPU, an hard disk or something else, depending on the OS and its configuration). All temperatures are expressed in celsius unless *fahrenheit* is set to ``True``. If sensors are not supported by the OS an empty dict is returned. Example:: >>> import psutil >>> psutil.sensors_temperatures() {'acpitz': [shwtemp(label='', current=47.0, high=103.0, critical=103.0)], 'asus': [shwtemp(label='', current=47.0, high=None, critical=None)], 'coretemp': [shwtemp(label='Physical id 0', current=52.0, high=100.0, critical=100.0), shwtemp(label='Core 0', current=45.0, high=100.0, critical=100.0), shwtemp(label='Core 1', current=52.0, high=100.0, critical=100.0), shwtemp(label='Core 2', current=45.0, high=100.0, critical=100.0), shwtemp(label='Core 3', current=47.0, high=100.0, critical=100.0)]} See also `temperatures.py `__ and `sensors.py `__ for an example application. Availability: Linux .. versionadded:: 5.1.0 .. warning:: this API is experimental. Backward incompatible changes may occur if deemed necessary. .. function:: sensors_fans() Return hardware fans speed. Each entry is a named tuple representing a certain hardware sensor fan. Fan speed is expressed in RPM (rounds per minute). If sensors are not supported by the OS an empty dict is returned. Example:: >>> import psutil >>> psutil.sensors_fans() {'asus': [sfan(label='cpu_fan', current=3200)]} See also `fans.py `__ and `sensors.py `__ for an example application. Availability: Linux .. versionadded:: 5.2.0 .. warning:: this API is experimental. Backward incompatible changes may occur if deemed necessary. .. function:: sensors_battery() Return battery status information as a named tuple including the following values. If no battery is installed or metrics can't be determined ``None`` is returned. - **percent**: battery power left as a percentage. - **secsleft**: a rough approximation of how many seconds are left before the battery runs out of power. If the AC power cable is connected this is set to :data:`psutil.POWER_TIME_UNLIMITED `. If it can't be determined it is set to :data:`psutil.POWER_TIME_UNKNOWN `. - **power_plugged**: ``True`` if the AC power cable is connected, ``False`` if not or ``None`` if it can't be determined. Example:: >>> import psutil >>> >>> def secs2hours(secs): ... mm, ss = divmod(secs, 60) ... hh, mm = divmod(mm, 60) ... return "%d:%02d:%02d" % (hh, mm, ss) ... >>> battery = psutil.sensors_battery() >>> battery sbattery(percent=93, secsleft=16628, power_plugged=False) >>> print("charge = %s%%, time left = %s" % (batt.percent, secs2hours(batt.secsleft))) charge = 93%, time left = 4:37:08 See also `battery.py `__ and `sensors.py `__ for an example application. Availability: Linux, Windows, FreeBSD .. versionadded:: 5.1.0 .. versionchanged:: 5.4.2 added OSX support .. warning:: this API is experimental. Backward incompatible changes may occur if deemed necessary. Other system info ----------------- .. function:: boot_time() Return the system boot time expressed in seconds since the epoch. Example: .. code-block:: python >>> import psutil, datetime >>> psutil.boot_time() 1389563460.0 >>> datetime.datetime.fromtimestamp(psutil.boot_time()).strftime("%Y-%m-%d %H:%M:%S") '2014-01-12 22:51:00' .. note:: on Windows this function may return a time which is off by 1 second if it's used across different processes (see `issue #1007 `__). .. function:: users() Return users currently connected on the system as a list of named tuples including the following fields: - **user**: the name of the user. - **terminal**: the tty or pseudo-tty associated with the user, if any, else ``None``. - **host**: the host name associated with the entry, if any. - **started**: the creation time as a floating point number expressed in seconds since the epoch. - **pid**: the PID of the login process (like sshd, tmux, gdm-session-worker, ...). On Windows and OpenBSD this is always set to ``None``. Example:: >>> import psutil >>> psutil.users() [suser(name='giampaolo', terminal='pts/2', host='localhost', started=1340737536.0, pid=1352), suser(name='giampaolo', terminal='pts/3', host='localhost', started=1340737792.0, pid=1788)] .. versionchanged:: 5.3.0 added "pid" field Processes ========= Functions --------- .. function:: pids() Return a list of current running PIDs. To iterate over all processes and avoid race conditions :func:`process_iter()` should be preferred. >>> import psutil >>> psutil.pids() [1, 2, 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, ..., 32498] .. function:: process_iter(attrs=None, ad_value=None) Return an iterator yielding a :class:`Process` class instance for all running processes on the local machine. Every instance is only created once and then cached into an internal table which is updated every time an element is yielded. Cached :class:`Process` instances are checked for identity so that you're safe in case a PID has been reused by another process, in which case the cached instance is updated. This is should be preferred over :func:`psutil.pids()` for iterating over processes. Sorting order in which processes are returned is based on their PID. *attrs* and *ad_value* have the same meaning as in :meth:`Process.as_dict()`. If *attrs* is specified :meth:`Process.as_dict()` is called interanally and the resulting dict is stored as a ``info`` attribute which is attached to the returned :class:`Process` instances. If *attrs* is an empty list it will retrieve all process info (slow). Example usage:: >>> import psutil >>> for proc in psutil.process_iter(): ... try: ... pinfo = proc.as_dict(attrs=['pid', 'name', 'username']) ... except psutil.NoSuchProcess: ... pass ... else: ... print(pinfo) ... {'name': 'systemd', 'pid': 1, 'username': 'root'} {'name': 'kthreadd', 'pid': 2, 'username': 'root'} {'name': 'ksoftirqd/0', 'pid': 3, 'username': 'root'} ... More compact version using *attrs* parameter:: >>> import psutil >>> for proc in psutil.process_iter(attrs=['pid', 'name', 'username']): ... print(proc.info) ... {'name': 'systemd', 'pid': 1, 'username': 'root'} {'name': 'kthreadd', 'pid': 2, 'username': 'root'} {'name': 'ksoftirqd/0', 'pid': 3, 'username': 'root'} ... Example of a dict comprehensions to create a ``{pid: info, ...}`` data structure:: >>> import psutil >>> procs = {p.pid: p.info for p in psutil.process_iter(attrs=['name', 'username'])} >>> procs {1: {'name': 'systemd', 'username': 'root'}, 2: {'name': 'kthreadd', 'username': 'root'}, 3: {'name': 'ksoftirqd/0', 'username': 'root'}, ...} Example showing how to filter processes by name:: >>> import psutil >>> [p.info for p in psutil.process_iter(attrs=['pid', 'name']) if 'python' in p.info['name']] [{'name': 'python3', 'pid': 21947}, {'name': 'python', 'pid': 23835}] See also `process filtering <#filtering-and-sorting-processes>`__ section for more examples. .. versionchanged:: 5.3.0 added "attrs" and "ad_value" parameters. .. function:: pid_exists(pid) Check whether the given PID exists in the current process list. This is faster than doing ``pid in psutil.pids()`` and should be preferred. .. function:: wait_procs(procs, timeout=None, callback=None) Convenience function which waits for a list of :class:`Process` instances to terminate. Return a ``(gone, alive)`` tuple indicating which processes are gone and which ones are still alive. The *gone* ones will have a new *returncode* attribute indicating process exit status (will be ``None`` for processes which are not our children). ``callback`` is a function which gets called when one of the processes being waited on is terminated and a :class:`Process` instance is passed as callback argument). This tunction will return as soon as all processes terminate or when *timeout* occurs, if specified. Differently from :meth:`Process.wait` it will not raise :class:`TimeoutExpired` if timeout occurs. A typical use case may be: - send SIGTERM to a list of processes - give them some time to terminate - send SIGKILL to those ones which are still alive Example which terminates and waits all the children of this process:: import psutil def on_terminate(proc): print("process {} terminated with exit code {}".format(proc, proc.returncode)) procs = psutil.Process().children() for p in procs: p.terminate() gone, alive = psutil.wait_procs(procs, timeout=3, callback=on_terminate) for p in alive: p.kill() Exceptions ---------- .. class:: Error() Base exception class. All other exceptions inherit from this one. .. class:: NoSuchProcess(pid, name=None, msg=None) Raised by :class:`Process` class methods when no process with the given *pid* is found in the current process list or when a process no longer exists. *name* is the name the process had before disappearing and gets set only if :meth:`Process.name()` was previously called. .. class:: ZombieProcess(pid, name=None, ppid=None, msg=None) This may be raised by :class:`Process` class methods when querying a zombie process on UNIX (Windows doesn't have zombie processes). Depending on the method called the OS may be able to succeed in retrieving the process information or not. Note: this is a subclass of :class:`NoSuchProcess` so if you're not interested in retrieving zombies (e.g. when using :func:`process_iter()`) you can ignore this exception and just catch :class:`NoSuchProcess`. .. versionadded:: 3.0.0 .. class:: AccessDenied(pid=None, name=None, msg=None) Raised by :class:`Process` class methods when permission to perform an action is denied. "name" is the name of the process (may be ``None``). .. class:: TimeoutExpired(seconds, pid=None, name=None, msg=None) Raised by :meth:`Process.wait` if timeout expires and process is still alive. Process class ------------- .. class:: Process(pid=None) Represents an OS process with the given *pid*. If *pid* is omitted current process *pid* (`os.getpid() `__) is used. Raise :class:`NoSuchProcess` if *pid* does not exist. On Linux *pid* can also refer to a thread ID (the *id* field returned by :meth:`threads` method). When accessing methods of this class always be prepared to catch :class:`NoSuchProcess`, :class:`ZombieProcess` and :class:`AccessDenied` exceptions. `hash() `__ builtin can be used against instances of this class in order to identify a process univocally over time (the hash is determined by mixing process PID and creation time). As such it can also be used with `set()s `__. .. note:: In order to efficiently fetch more than one information about the process at the same time, make sure to use either :meth:`as_dict` or :meth:`oneshot` context manager. .. note:: the way this class is bound to a process is uniquely via its **PID**. That means that if the process terminates and the OS reuses its PID you may end up interacting with another process. The only exceptions for which process identity is preemptively checked (via PID + creation time) is for the following methods: :meth:`nice` (set), :meth:`ionice` (set), :meth:`cpu_affinity` (set), :meth:`rlimit` (set), :meth:`children`, :meth:`parent`, :meth:`suspend` :meth:`resume`, :meth:`send_signal`, :meth:`terminate` :meth:`kill`. To prevent this problem for all other methods you can use :meth:`is_running()` before querying the process or :func:`process_iter()` in case you're iterating over all processes. It must be noted though that unless you deal with very "old" (inactive) :class:`Process` instances this will hardly represent a problem. .. method:: oneshot() Utility context manager which considerably speeds up the retrieval of multiple process information at the same time. Internally different process info (e.g. :meth:`name`, :meth:`ppid`, :meth:`uids`, :meth:`create_time`, ...) may be fetched by using the same routine, but only one value is returned and the others are discarded. When using this context manager the internal routine is executed once (in the example below on :meth:`name()`) the value of interest is returned and the others are cached. The subsequent calls sharing the same internal routine will return the cached value. The cache is cleared when exiting the context manager block. The advice is to use this every time you retrieve more than one information about the process. If you're lucky, you'll get a hell of a speedup. Example: >>> import psutil >>> p = psutil.Process() >>> with p.oneshot(): ... p.name() # execute internal routine once collecting multiple info ... p.cpu_times() # return cached value ... p.cpu_percent() # return cached value ... p.create_time() # return cached value ... p.ppid() # return cached value ... p.status() # return cached value ... >>> Here's a list of methods which can take advantage of the speedup depending on what platform you're on. In the table below horizontal emtpy rows indicate what process methods can be efficiently grouped together internally. The last column (speedup) shows an approximation of the speedup you can get if you call all the methods together (best case scenario).

On UNIX this is calculated by using real process uid. .. method:: uids() The real, effective and saved user ids of this process as a named tuple. This is the same as `os.getresuid() `__ but can be used for any process PID. Availability: UNIX .. method:: gids() The real, effective and saved group ids of this process as a named tuple. This is the same as `os.getresgid() `__ but can be used for any process PID. Availability: UNIX .. method:: terminal() The terminal associated with this process, if any, else ``None``.

The higher the nice value, the lower the priority of the process. >>> import psutil >>> p = psutil.Process() >>> p.nice(10) # set >>> p.nice() # get 10 >>> Starting from `Python 3.3 `__ this functionality is also available as `os.getpriority() `__ and `os.setpriority() `__ (UNIX only). On Windows this is implemented via `GetPriorityClass `__ and `SetPriorityClass `__ Windows APIs and *value* is one of the :data:`psutil.*_PRIORITY_CLASS ` constants reflecting the MSDN documentation.

The example below sets IDLE priority class for the current process, meaning it will only get I/O time when no other process needs the disk: >>> import psutil >>> p = psutil.Process() >>> p.ionice(psutil.IOPRIO_CLASS_IDLE) # set >>> p.ionice() # get pionice(ioclass=, value=0) >>> On Windows only *ioclass* is used and it can be set to ``2`` (normal), ``1`` (low) or ``0`` (very low). Also it returns an integer instead of a named tuple. Availability: Linux and Windows > Vista .. versionchanged:: 3.0.0 on Python >= 3.4 the returned ``ioclass`` constant is an `enum `__ instead of a plain integer. .. method:: rlimit(resource, limits=None) Get or set process resource limits (see `man prlimit `__). *resource* is one of the :data:`psutil.RLIMIT_* ` constants. *limits* is a ``(soft, hard)`` tuple. This is the same as `resource.getrlimit() `__ and `resource.setrlimit() `__ but can be used for any process PID, not only `os.getpid() `__. For get, return value is a ``(soft, hard)`` tuple. Each value may be either and integer or :data:`psutil.RLIMIT_* `. Example: >>> import psutil >>> p = psutil.Process() >>> # process may open no more than 128 file descriptors >>> p.rlimit(psutil.RLIMIT_NOFILE, (128, 128)) >>> # process may create files no bigger than 1024 bytes >>> p.rlimit(psutil.RLIMIT_FSIZE, (1024, 1024)) >>> # get >>> p.rlimit(psutil.RLIMIT_FSIZE) (1024, 1024) >>> Availability: Linux .. method:: io_counters() Return process I/O statistics as a named tuple. For Linux you can refer to `/proc filesysem documentation `__. - **read_count**: the number of read operations performed (cumulative). This is supposed to count the number of read-related syscalls such as ``read()`` and ``pread()`` on UNIX. - **write_count**: the number of write operations performed (cumulative). This is supposed to count the number of write-related syscalls such as ``write()`` and ``pwrite()`` on UNIX. - **read_bytes**: the number of bytes read (cumulative). Always ``-1`` on BSD. - **write_bytes**: the number of bytes written (cumulative). Always ``-1`` on BSD. Linux specific: - **read_chars** *(Linux)*: the amount of bytes which this process passed to ``read()`` and ``pread()`` syscalls (cumulative). Differently from *read_bytes* it doesn't care whether or not actual physical disk I/O occurred. - **write_chars** *(Linux)*: the amount of bytes which this process passed to ``write()`` and ``pwrite()`` syscalls (cumulative). Differently from *write_bytes* it doesn't care whether or not actual physical disk I/O occurred. Windows specific: - **other_count** *(Windows)*: the number of I/O operations performed other than read and write operations. - **other_bytes** *(Windows)*: the number of bytes transferred during operations other than read and write operations. >>> import psutil >>> p = psutil.Process() >>> p.io_counters() pio(read_count=454556, write_count=3456, read_bytes=110592, write_bytes=0, read_chars=769931, write_chars=203) Availability: Linux, BSD, Windows, AIX .. versionchanged:: 5.2.0 added *read_chars* and *write_chars* on Linux; added *other_count* and *other_bytes* on Windows. .. method:: num_ctx_switches() The number voluntary and involuntary context switches performed by this process (cumulative). .. versionchanged:: 5.4.1 added AIX support .. method:: num_fds() The number of file descriptors currently opened by this process (non cumulative). Availability: UNIX .. method:: num_handles() The number of handles currently used by this process (non cumulative). Availability: Windows .. method:: num_threads() The number of threads currently used by this process (non cumulative). .. method:: threads() Return threads opened by process as a list of named tuples including thread id and thread CPU times (user/system). On OpenBSD this method requires root privileges. .. method:: cpu_times() Return a `(user, system, children_user, children_system)` named tuple representing the accumulated process time, in seconds (see `explanation `__). On Windows and OSX only *user* and *system* are filled, the others are set to ``0``. This is similar to `os.times() `__ but can be used for any process PID. .. versionchanged:: 4.1.0 return two extra fields: *children_user* and *children_system*. .. method:: cpu_percent(interval=None) Return a float representing the process CPU utilization as a percentage which can also be ``> 100.0`` in case of a process running multiple threads on different CPUs. When *interval* is > ``0.0`` compares process times to system CPU times elapsed before and after the interval (blocking). When interval is ``0.0`` or ``None`` compares process times to system CPU times elapsed since last call, returning immediately. That means the first time this is called it will return a meaningless ``0.0`` value which you are supposed to ignore. In this case is recommended for accuracy that this function be called a second time with at least ``0.1`` seconds between calls. Example: >>> import psutil >>> p = psutil.Process() >>> # blocking >>> p.cpu_percent(interval=1) 2.0 >>> # non-blocking (percentage since last call) >>> p.cpu_percent(interval=None) 2.9 .. note:: the returned value can be > 100.0 in case of a process running multiple threads on different CPU cores. .. note:: the returned value is explicitly *not* split evenly between all available CPUs (differently from :func:`psutil.cpu_percent()`). This means that a busy loop process running on a system with 2 logical CPUs will be reported as having 100% CPU utilization instead of 50%. This was done in order to be consistent with ``top`` UNIX utility and also to make it easier to identify processes hogging CPU resources independently from the number of CPUs. It must be noted that ``taskmgr.exe`` on Windows does not behave like this (it would report 50% usage instead). To emulate Windows ``taskmgr.exe`` behavior you can do: ``p.cpu_percent() / psutil.cpu_count()``. .. warning:: the first time this method is called with interval = ``0.0`` or ``None`` it will return a meaningless ``0.0`` value which you are supposed to ignore. .. method:: cpu_affinity(cpus=None) Get or set process current `CPU affinity `__. CPU affinity consists in telling the OS to run a process on a limited set of CPUs only (on Linux cmdline, ``taskset`` command is typically used). If no argument is passed it returns the current CPU affinity as a list of integers. If passed it must be a list of integers specifying the new CPUs affinity. If an empty list is passed all eligible CPUs are assumed (and set). On some systems such as Linux this may not necessarily mean all available logical CPUs as in ``list(range(psutil.cpu_count()))``). >>> import psutil >>> psutil.cpu_count() 4 >>> p = psutil.Process() >>> # get >>> p.cpu_affinity() [0, 1, 2, 3] >>> # set; from now on, process will run on CPU #0 and #1 only >>> p.cpu_affinity([0, 1]) >>> p.cpu_affinity() [0, 1] >>> # reset affinity against all eligible CPUs >>> p.cpu_affinity([]) Availability: Linux, Windows, FreeBSD .. versionchanged:: 2.2.0 added support for FreeBSD .. versionchanged:: 5.1.0 an empty list can be passed to set affinity against all eligible CPUs. .. method:: cpu_num() Return what CPU this process is currently running on. The returned number should be ``<=`` :func:`psutil.cpu_count()`. On FreeBSD certain kernel process may return ``-1``. It may be used in conjunction with ``psutil.cpu_percent(percpu=True)`` to observe the system workload distributed across multiple CPUs as shown by `cpu_distribution.py `__ example script. Availability: Linux, FreeBSD, SunOS .. versionadded:: 5.1.0 .. method:: memory_info() Return a named tuple with variable fields depending on the platform representing memory information about the process. The "portable" fields available on all plaforms are `rss` and `vms`.

On UNIX it matches "top"'s RES column (see `doc `__). On Windows this is an alias for `wset` field and it matches "Mem Usage" column of taskmgr.exe. - **vms**: aka "Virtual Memory Size", this is the total amount of virtual memory used by the process. On UNIX it matches "top"'s VIRT column (see `doc `__). On Windows this is an alias for `pagefile` field and it matches "Mem Usage" "VM Size" column of taskmgr.exe. - **shared**: *(Linux)* memory that could be potentially shared with other processes. This matches "top"'s SHR column (see `doc `__). - **text** *(Linux, BSD)*: aka TRS (text resident set) the amount of memory devoted to executable code. This matches "top"'s CODE column (see `doc `__). - **data** *(Linux, BSD)*: aka DRS (data resident set) the amount of physical memory devoted to other than executable code. It matches "top"'s DATA column (see `doc `__). - **lib** *(Linux)*: the memory used by shared libraries. - **dirty** *(Linux)*: the number of dirty pages. - **pfaults** *(OSX)*: number of page faults. - **pageins** *(OSX)*: number of actual pageins. For on explanation of Windows fields rely on `PROCESS_MEMORY_COUNTERS_EX `__ structure doc. Example on Linux: >>> import psutil >>> p = psutil.Process() >>> p.memory_info() pmem(rss=15491072, vms=84025344, shared=5206016, text=2555904, lib=0, data=9891840, dirty=0) .. versionchanged:: 4.0.0 multiple fields are returned, not only `rss` and `vms`. .. method:: memory_info_ex() Same as :meth:`memory_info` (deprecated). .. warning:: deprecated in version 4.0.0; use :meth:`memory_info` instead. .. method:: memory_full_info() This method returns the same information as :meth:`memory_info`, plus, on some platform (Linux, OSX, Windows), also provides additional metrics (USS, PSS and swap). The additional metrics provide a better representation of "effective" process memory consumption (in case of USS) as explained in detail in this `blog post `__. It does so by passing through the whole process address. As such it usually requires higher user privileges than :meth:`memory_info` and is considerably slower. On platforms where extra fields are not implemented this simply returns the same metrics as :meth:`memory_info`. - **uss** *(Linux, OSX, Windows)*: aka "Unique Set Size", this is the memory which is unique to a process and which would be freed if the process was terminated right now. - **pss** *(Linux)*: aka "Proportional Set Size", is the amount of memory shared with other processes, accounted in a way that the amount is divided evenly between the processes that share it. I.e. if a process has 10 MBs all to itself and 10 MBs shared with another process its PSS will be 15 MBs. - **swap** *(Linux)*: amount of memory that has been swapped out to disk. .. note:: `uss` is probably the most representative metric for determining how much memory is actually being used by a process. It represents the amount of memory that would be freed if the process was terminated right now. Example on Linux: >>> import psutil >>> p = psutil.Process() >>> p.memory_full_info() pfullmem(rss=10199040, vms=52133888, shared=3887104, text=2867200, lib=0, data=5967872, dirty=0, uss=6545408, pss=6872064, swap=0) >>> See also `procsmem.py `__ for an example application. .. versionadded:: 4.0.0 .. method:: memory_percent(memtype="rss") Compare process memory to total physical system memory and calculate process memory utilization as a percentage. *memtype* argument is a string that dictates what type of process memory you want to compare against. You can choose between the named tuple field names returned by :meth:`memory_info` and :meth:`memory_full_info` (defaults to ``"rss"``). .. versionchanged:: 4.0.0 added `memtype` parameter. .. method:: memory_maps(grouped=True) Return process's mapped memory regions as a list of named tuples whose fields are variable depending on the platform. This method is useful to obtain a detailed representation of process memory usage as explained `here `__ (the most important value is "private" memory). If *grouped* is ``True`` the mapped regions with the same *path* are grouped together and the different memory fields are summed. If *grouped* is ``False`` each mapped region is shown as a single entity and the named tuple will also include the mapped region's address space (*addr*) and permission set (*perms*).

Also, it will only list files living in the C:\\ drive (see `issue 1020 `_). .. warning:: on BSD this method can return files with a null path ("") due to a kernel bug, hence it's not reliable (see `issue 595 `_). .. versionchanged:: 3.1.0 no longer hangs on Windows. .. versionchanged:: 4.1.0 new *position*, *mode* and *flags* fields on Linux. .. method:: connections(kind="inet") Return socket connections opened by process as a list of named tuples. To get system-wide connections use :func:`psutil.net_connections()`. Every named tuple provides 6 attributes: - **fd**: the socket file descriptor. This can be passed to `socket.fromfd() `__ to obtain a usable socket object. On Windows, FreeBSD and SunOS this is always set to ``-1``. - **family**: the address family, either `AF_INET `__, `AF_INET6 `__ or `AF_UNIX `__. - **type**: the address type, either `SOCK_STREAM `__ or `SOCK_DGRAM `__. - **laddr**: the local address as a ``(ip, port)`` named tuple or a ``path`` in case of AF_UNIX sockets. For UNIX sockets see notes below. - **raddr**: the remote address as a ``(ip, port)`` named tuple or an absolute ``path`` in case of UNIX sockets. When the remote endpoint is not connected you'll get an empty tuple (AF_INET*) or ``""`` (AF_UNIX). For UNIX sockets see notes below. - **status**: represents the status of a TCP connection. The return value is one of the :data:`psutil.CONN_* ` constants. For UDP and UNIX sockets this is always going to be :const:`psutil.CONN_NONE`. The *kind* parameter is a string which filters for connections that fit the following criteria: +----------------+-----------------------------------------------------+ | **Kind value** | **Connections using** | +================+=====================================================+ | ``"inet"`` | IPv4 and IPv6 | +----------------+-----------------------------------------------------+ | ``"inet4"`` | IPv4 | +----------------+-----------------------------------------------------+ | ``"inet6"`` | IPv6 | +----------------+-----------------------------------------------------+ | ``"tcp"`` | TCP | +----------------+-----------------------------------------------------+ | ``"tcp4"`` | TCP over IPv4 | +----------------+-----------------------------------------------------+ | ``"tcp6"`` | TCP over IPv6 | +----------------+-----------------------------------------------------+ | ``"udp"`` | UDP | +----------------+-----------------------------------------------------+ | ``"udp4"`` | UDP over IPv4 | +----------------+-----------------------------------------------------+ | ``"udp6"`` | UDP over IPv6 | +----------------+-----------------------------------------------------+ | ``"unix"`` | UNIX socket (both UDP and TCP protocols) | +----------------+-----------------------------------------------------+ | ``"all"`` | the sum of all the possible families and protocols | +----------------+-----------------------------------------------------+ Example: >>> import psutil >>> p = psutil.Process(1694) >>> p.name() 'firefox' >>> p.connections() [pconn(fd=115, family=, type=, laddr=addr(ip='10.0.0.1', port=48776), raddr=addr(ip='93.186.135.91', port=80), status='ESTABLISHED'), pconn(fd=117, family=, type=, laddr=addr(ip='10.0.0.1', port=43761), raddr=addr(ip='72.14.234.100', port=80), status='CLOSING'), pconn(fd=119, family=, type=, laddr=addr(ip='10.0.0.1', port=60759), raddr=addr(ip='72.14.234.104', port=80), status='ESTABLISHED'), pconn(fd=123, family=, type=, laddr=addr(ip='10.0.0.1', port=51314), raddr=addr(ip='72.14.234.83', port=443), status='SYN_SENT')] .. note:: (Solaris) UNIX sockets are not supported. .. note:: (Linux, FreeBSD) "raddr" field for UNIX sockets is always set to "". This is a limitation of the OS. .. note:: (OpenBSD) "laddr" and "raddr" fields for UNIX sockets are always set to "". This is a limitation of the OS. .. versionchanged:: 5.3.0 : "laddr" and "raddr" are named tuples. .. note:: (AIX) :class:`psutil.AccessDenied` is always raised unless running as root (lsof does the same). .. method:: is_running() Return whether the current process is running in the current process list. This is reliable also in case the process is gone and its PID reused by another process, therefore it must be preferred over doing ``psutil.pid_exists(p.pid)``. .. note:: this will return ``True`` also if the process is a zombie (``p.status() == psutil.STATUS_ZOMBIE``). .. method:: send_signal(signal) Send a signal to process (see `signal module `__ constants) preemptively checking whether PID has been reused. On UNIX this is the same as ``os.kill(pid, sig)``. On Windows only *SIGTERM*, *CTRL_C_EVENT* and *CTRL_BREAK_EVENT* signals are supported and *SIGTERM* is treated as an alias for :meth:`kill()`. See also how to `kill a process tree <#kill-process-tree>`__ and `terminate my children <#terminate-my-children>`__. .. versionchanged:: 3.2.0 support for CTRL_C_EVENT and CTRL_BREAK_EVENT signals on Windows was added. .. method:: suspend() Suspend process execution with *SIGSTOP* signal preemptively checking whether PID has been reused. On UNIX this is the same as ``os.kill(pid, signal.SIGSTOP)``. On Windows this is done by suspending all process threads execution. .. method:: resume() Resume process execution with *SIGCONT* signal preemptively checking whether PID has been reused. On UNIX this is the same as ``os.kill(pid, signal.SIGCONT)``. On Windows this is done by resuming all process threads execution. .. method:: terminate() Terminate the process with *SIGTERM* signal preemptively checking whether PID has been reused. On UNIX this is the same as ``os.kill(pid, signal.SIGTERM)``. On Windows this is an alias for :meth:`kill`. See also how to `kill a process tree <#kill-process-tree>`__ and `terminate my children <#terminate-my-children>`__. .. method:: kill() Kill the current process by using *SIGKILL* signal preemptively checking whether PID has been reused. On UNIX this is the same as ``os.kill(pid, signal.SIGKILL)``. On Windows this is done by using `TerminateProcess `__. See also how to `kill a process tree <#kill-process-tree>`__ and `terminate my children <#terminate-my-children>`__. .. method:: wait(timeout=None) Wait for process termination and if the process is a children of the current one also return the exit code, else ``None``. On Windows there's no such limitation (exit code is always returned). If the process is already terminated immediately return ``None`` instead of raising :class:`NoSuchProcess`. If *timeout* is specified and process is still alive raise :class:`TimeoutExpired` exception. It can also be used in a non-blocking fashion by specifying ``timeout=0`` in which case it will either return immediately or raise :class:`TimeoutExpired`. To wait for multiple processes use :func:`psutil.wait_procs()`. >>> import psutil >>> p = psutil.Process(9891) >>> p.terminate() >>> p.wait() Popen class ----------- .. class:: Popen(*args, **kwargs) A more convenient interface to stdlib `subprocess.Popen `__. It starts a sub process and you deal with it exactly as when using `subprocess.Popen `__ but in addition it also provides all the methods of :class:`psutil.Process` class. For method names common to both classes such as :meth:`send_signal() `, :meth:`terminate() ` and :meth:`kill() ` :class:`psutil.Process` implementation takes precedence. For a complete documentation refer to `subprocess module documentation `__. .. note:: Unlike `subprocess.Popen `__ this class preemptively checks whether PID has been reused on :meth:`send_signal() `, :meth:`terminate() ` and :meth:`kill() ` so that you can't accidentally terminate another process, fixing http://bugs.python.org/issue6973. >>> import psutil >>> from subprocess import PIPE >>> >>> p = psutil.Popen(["/usr/bin/python", "-c", "print('hello')"], stdout=PIPE) >>> p.name() 'python' >>> p.username() 'giampaolo' >>> p.communicate() ('hello\n', None) >>> p.wait(timeout=2) 0 >>> :class:`psutil.Popen` objects are supported as context managers via the with statement: on exit, standard file descriptors are closed, and the process is waited for.

Example: >>> import psutil >>> if psutil.version_info >= (4, 5): ... pass ---- Unicode ======= Starting from version 5.3.0 psutil fully supports unicode, see `issue #1040 `__. The notes below apply to *any* API returning a string such as :meth:`Process.exe` or :meth:`Process.cwd`, including non-filesystem related methods such as :meth:`Process.username` or :meth:`WindowsService.description`: * all strings are encoded by using the OS filesystem encoding (``sys.getfilesystemencoding()``) which varies depending on the platform (e.g. "UTF-8" on OSX, "mbcs" on Win) * no API call is supposed to crash with ``UnicodeDecodeError`` * instead, in case of badly encoded data returned by the OS, the following error handlers are used to replace the corrupted characters in the string: * Python 3: ``sys.getfilesystemencodeerrors()`` (PY 3.6+) or ``"surrogatescape"`` on POSIX and ``"replace"`` on Windows * Python 2: ``"replace"`` * on Python 2 all APIs return bytes (``str`` type), never ``unicode`` * on Python 2, you can go back to ``unicode`` by doing: .. code-block:: python >>> unicode(p.exe(), sys.getdefaultencoding(), errors="replace") Example which filters processes with a funky name working with both Python 2 and 3:: # -*- coding: utf-8 -*- import psutil, sys PY3 = sys.version_info[0] == 2 LOOKFOR = u"ƒőő" for proc in psutil.process_iter(attrs=['name']): name = proc.info['name'] if not PY3: name = unicode(name, sys.getdefaultencoding(), errors="replace") if LOOKFOR == name: print("process %s found" % p) Recipes ======= Follows a collection of utilities and examples which are common but not generic enough to be part of the public API.

Latest binary (wheel / exe) release which supports Windows **2000**, **XP** and **2003 server** is `psutil 3.4.2 `__. On such old systems psutil is no longer tested or maintained, but it can still be compiled from sources (you'll need `Visual Studio <(https://github.com/giampaolo/psutil/blob/master/INSTALL.rst#windows>`__) and it should "work" (more or less). ---- * Q: What Python versions are supported? * A: From 2.6 to 3.6, both 32 and 64 bit versions. Last version supporting Python 2.4 and 2.5 is `psutil 2.1.3 `__. PyPy is also known to work. ---- * Q: What SunOS versions are supported? * A: From Solaris 10 onwards. ---- * Q: Why do I get :class:`AccessDenied` for certain processes? * A: This may happen when you query processess owned by another user, especially on `OSX `__ and Windows. Unfortunately there's not much you can do about this except running the Python process with higher privileges. On Unix you may run the the Python process as root or use the SUID bit (this is the trick used by tools such as ``ps`` and ``netstat``). On Windows you may run the Python process as NT AUTHORITY\\SYSTEM or install the Python script as a Windows service (this is the trick used by tools such as ProcessHacker). ---- * Q: What about load average? * A: psutil does not expose any load average function as it's already available in python as `os.getloadavg `__. Running tests ============= There are two ways of running tests. If psutil is already installed use:: $ python -m psutil.tests You can use this method as a quick way to make sure psutil fully works on your platform. If you have a copy of the source code you can also use:: $ make test Development guide ================= If you plan on hacking on psutil (e.g. want to add a new feature or fix a bug) take a look at the `development guide `_.

It is useful mainly for **system monitoring**, **profiling and limiting process resources** and **management of running processes**. It implements many functionalities offered by UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. psutil currently supports the following platforms: - **Linux** - **Windows** - **OSX**, - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** ...both **32-bit** and **64-bit** architectures, with Python versions from **2.6 to 3.6**. `PyPy `__ is also known to work. ==================== Example applications ==================== +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/top-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/top.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ Also see `scripts directory `__ and `doc recipes `__. ===================== Projects using psutil ===================== At the time of writing psutil has roughly `2.9 milion downloads `__ per month and there are over `6000 open source projects `__ on github which depend from psutil.

It is useful mainly for system \ monitoring, profiling and limiting process resources and management of \ running processes. It implements many functionalities offered by command \ line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, \ nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It \ currently supports Linux, Windows, OSX, Sun Solaris, FreeBSD, OpenBSD, NetBSD \ and AIX, both 32-bit and 64-bit architectures, with Python versions from 2.6 \ to 3.6. PyPy is also known to work.

There are a ton of a solutions available for validating URLs in string using regex, but less for searching, of which very few are accurate. This snippet is intended to just do the required work, and avoid complexities. Django Validator has pretty good regex for validation, but we have to find urls instead of validating them (REFERENCES [7]). There's always room for improvement. Method: * Match URLs using regex (REFERENCES [1]]) * Some URLs need to be fixed, as they have < (or) > due to inefficient regex. * Remove duplicates (because regex is not 100% efficient as of now). * Check validity of URL, using HEAD request. (HEAD to save bandwidth) Uses requests module for others are painful to use. REFERENCES[9] Handles redirects, http, https, ftp as well.

It is shipped by default with Python 2.7.9+ and 3.4+. For other Python versions you can install it manually. On Linux or via wget: .. code-block:: bash wget https://bootstrap.pypa.io/get-pip.py -O - | python On OSX or via curl: .. code-block:: bash python < <(curl -s https://bootstrap.pypa.io/get-pip.py) On Windows, `download pip `__, open cmd.exe and install it: .. code-block:: bat C:\Python27\python.exe get-pip.py Permission issues (UNIX) ======================== The commands below assume you're running as root. If you're not or you bump into permission errors you can either: * prepend ``sudo``, e.g.: .. code-block:: bash sudo pip install psutil * install psutil for your user only (not at system level): .. code-block:: bash pip install --user psutil Linux ===== Ubuntu / Debian: .. code-block:: bash sudo apt-get install gcc python-dev python-pip pip install psutil RedHat / CentOS: .. code-block:: bash sudo yum install gcc python-devel python-pip pip install psutil If you're on Python 3 use ``python3-dev`` and ``python3-pip`` instead. OSX === Install `Xcode `__ first, then: .. code-block:: bash pip install psutil Windows ======= The easiest way to install psutil on Windows is to just use the pre-compiled exe/wheel installers hosted on `PYPI `__ via pip: .. code-block:: bat C:\Python27\python.exe -m pip install psutil If you want to compile psutil from sources you'll need **Visual Studio** (Mingw32 is no longer supported): * Python 2.6, 2.7: `VS-2008 `__ * Python 3.3, 3.4: `VS-2010 `__ * Python 3.5+: `VS-2015 `__ Compiling 64 bit versions of Python 2.6 and 2.7 with VS 2008 requires `Windows SDK and .NET Framework 3.5 SP1 `__. Once installed run vcvars64.bat, then you can finally compile (see `here `__). To compile / install psutil from sources on Windows run: .. code-block:: bat make.bat build make.bat install FreeBSD ======= .. code-block:: bash pkg install python gcc python -m pip install psutil OpenBSD ======= .. code-block:: bash export PKG_PATH="http://ftp.openbsd.org/pub/OpenBSD/`uname -r`/packages/`arch -s`/" pkg_add -v python gcc python -m pip install psutil NetBSD ====== .. code-block:: bash export PKG_PATH="ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/`uname -r`/All" pkg_add -v pkgin pkgin install python gcc python -m pip install psutil Solaris ======= If ``cc`` compiler is not installed create a symlink to ``gcc``: .. code-block:: bash sudo ln -s /usr/bin/gcc /usr/local/bin/cc Install: .. code-block:: bash pkg install gcc python -m pip install psutil Install from sources ==================== .. code-block:: bash git clone https://github.com/giampaolo/psutil.git cd psutil python setup.py install Dev Guide ========= If you plan on hacking on psutil you may want to take a look at the `dev guide `__. psutil-5.4.2/CREDITS0000664000175000017500000001743113206014576016040 0ustar giampaologiampaolo00000000000000Intro ===== I would like to recognize some of the people who have been instrumental in the development of psutil.

(patch by Arnon Yaari) - 1183_: Process.children() is 2x faster on UNIX and 2.4x faster on Linux. - 1188_: deprecated method Process.memory_info_ex() now warns by using FutureWarning instead of DeprecationWarning. **Bug fixes** - 1152_: [Windows] disk_io_counters() may return an empty dict. - 1169_: [Linux] users() "hostname" returns username instead. (patch by janderbrain) - 1172_: [Windows] `make test` does not work. - 1179_: [Linux] Process.cmdline() is now able to splits cmdline args for misbehaving processes which overwrite /proc/pid/cmdline and use spaces instead of null bytes as args separator. - 1181_: [OSX] Process.memory_maps() may raise ENOENT. - 1187_: [OSX] pids() does not return PID 0 on recent OSX versions. 5.4.1 ===== *2017-11-08* **Enhancements** - 1164_: [AIX] add support for Process.num_ctx_switches(). (patch by Arnon Yaari) - 1053_: abandon Python 3.3 support (psutil still works but it's no longer tested). **Bug fixes** - 1150_: [Windows] when a process is terminate()d now the exit code is set to SIGTERM instead of 0. (patch by Akos Kiss) - 1151_: python -m psutil.tests fail - 1154_: [AIX] psutil won't compile on AIX 6.1.0. (patch by Arnon Yaari) - 1167_: [Windows] net_io_counter() packets count now include also non-unicast packets. (patch by Matthew Long) 5.4.0 ===== *2017-10-12* **Enhancements** - 1123_: [AIX] added support for AIX platform. (patch by Arnon Yaari) **Bug fixes** - 1009_: [Linux] sensors_temperatures() may crash with IOError. - 1012_: [Windows] disk_io_counters()'s read_time and write_time were expressed in tens of micro seconds instead of milliseconds. - 1127_: [OSX] invalid reference counting in Process.open_files() may lead to segfault. (patch by Jakub Bacic) - 1129_: [Linux] sensors_fans() may crash with IOError. (patch by Sebastian Saip) - 1131_: [SunOS] fix compilation warnings. (patch by Arnon Yaari) - 1133_: [Windows] can't compile on newer versions of Visual Studio 2017 15.4. (patch by Max Bélanger) - 1138_: [Linux] can't compile on CentOS 5.0 and RedHat 5.0. (patch by Prodesire) 5.3.1 ===== *2017-09-10* **Enhancements** - 1124_: documentation moved to http://psutil.readthedocs.io **Bug fixes** - 1105_: [FreeBSD] psutil does not compile on FreeBSD 12. - 1125_: [BSD] net_connections() raises TypeError. **Compatibility notes** - 1120_: .exe files for Windows are no longer uploaded on PYPI as per PEP-527; only wheels are provided. 5.3.0 ===== *2017-09-01* **Enhancements** - 802_: disk_io_counters() and net_io_counters() numbers no longer wrap (restart from 0). Introduced a new "nowrap" argument. - 928_: psutil.net_connections() and psutil.Process.connections() "laddr" and "raddr" are now named tuples. - 1015_: swap_memory() now relies on /proc/meminfo instead of sysinfo() syscall so that it can be used in conjunction with PROCFS_PATH in order to retrieve memory info about Linux containers such as Docker and Heroku. - 1022_: psutil.users() provides a new "pid" field. - 1025_: process_iter() accepts two new parameters in order to invoke Process.as_dict(): "attrs" and "ad_value". With this you can iterate over all processes in one shot without needing to catch NoSuchProcess and do list/dict comprehensions. - 1040_: implemented full unicode support. - 1051_: disk_usage() on Python 3 is now able to accept bytes. - 1058_: test suite now enables all warnings by default. - 1060_: source distribution is dynamically generated so that it only includes relevant files. - 1079_: [FreeBSD] net_connections()'s fd number is now being set for real (instead of -1). (patch by Gleb Smirnoff) - 1091_: [SunOS] implemented Process.environ().

longer returns immediately (see issue 123). - psutil.Process.get_cpu_percent() and psutil.cpu_percent() no longer returns immediately by default (see issue 123). 0.1.3 ===== *2010-03-02* **Enhancements** - 14_: per-process username - 51_: per-process current working directory (Windows and Linux only) - 59_: Process.is_running() is now 10 times faster - 61_: added supoprt for FreeBSD 64 bit - 71_: implemented suspend/resume process - 75_: python 3 support **Bug fixes** - 36_: process cpu_times() and memory_info() functions succeeded also for dead processes while a NoSuchProcess exception is supposed to be raised. - 48_: incorrect size for mib array defined in getcmdargs for BSD - 49_: possible memory leak due to missing free() on error condition on - 50_: fixed getcmdargs() memory fragmentation on BSD - 55_: test_pid_4 was failing on Windows Vista - 57_: some unit tests were failing on systems where no swap memory is available - 58_: is_running() is now called before kill() to make sure we are going to kill the correct process. - 73_: virtual memory size reported on OS X includes shared library size - 77_: NoSuchProcess wasn't raised on Process.create_time if kill() was used first. 0.1.2 ===== *2009-05-06* **Enhancements** - 32_: Per-process CPU user/kernel times - 33_: Process create time - 34_: Per-process CPU utilization percentage - 38_: Per-process memory usage (bytes) - 41_: Per-process memory utilization (percent) - 39_: System uptime - 43_: Total system virtual memory - 46_: Total system physical memory - 44_: Total system used/free virtual and physical memory **Bug fixes** - 36_: [Windows] NoSuchProcess not raised when accessing timing methods. - 40_: test_get_cpu_times() failing on FreeBSD and OS X. - 42_: [Windows] get_memory_percent() raises AccessDenied. 0.1.1 ===== *2009-03-06* **Enhancements** - 4_: FreeBSD support for all functions of psutil - 9_: Process.uid and Process.gid now retrieve process UID and GID. - 11_: Support for parent/ppid - Process.parent property returns a Process object representing the parent process, and Process.ppid returns the parent PID. - 12_ & 15: NoSuchProcess exception now raised when creating an object for a nonexistent process, or when retrieving information about a process that has gone away. - 21_: AccessDenied exception created for raising access denied errors from OSError or WindowsError on individual platforms. - 26_: psutil.process_iter() function to iterate over processes as Process objects with a generator. - Process objects can now also be compared with == operator for equality (PID, name, command line are compared). **Bug fixes** - 16_: [Windows] Special case for "System Idle Process" (PID 0) which otherwise would return an "invalid parameter" exception. - 17_: get_process_list() ignores NoSuchProcess and AccessDenied exceptions during building of the list. - 22_: [Windows] Process(0).kill() was failing with an unset exception. - 23_: Special case for pid_exists(0) - 24_: [Windows] Process(0).kill() now raises AccessDenied exception instead of WindowsError. - 30_: psutil.get_pid_list() was returning two ins .. _1:

giampaologiampaolo00000000000000======================= Setup and running tests ======================= If you plan on hacking on psutil this is what you're supposed to do first: - clone the GIT repository: .. code-block:: bash $ git clone git@github.com:giampaolo/psutil.git - install test deps and GIT hooks: .. code-block:: bash make setup-dev-env - run tests: .. code-block:: bash make test - bear in mind that ``make`` (see `Makefile `_) is the designated tool to run tests, build, install etc. and that it is also available on Windows (see `make.bat `_). - do not use ``sudo``; ``make install`` installs psutil as a limited user in "edit" mode; also ``make setup-dev-env`` installs deps as a limited user. - use `make help` to see the list of available commands. ============ Coding style ============ - python code strictly follows `PEP 8 `_ styling guides and this is enforced by ``make install-git-hooks``. - C code strictly follows `PEP 7 `_ styling guides. ======== Makefile ======== Some useful make commands: .. code-block:: bash make install # install make setup-dev-env # install useful dev libs (pyflakes, unittest2, etc.) make test # run unit tests make test-memleaks # run memory leak tests make test-coverage # run test coverage make flake8 # run PEP8 linter There are some differences between ``make`` on UNIX and Windows. For instance, to run a specific Python version. On UNIX: .. code-block:: bash make test PYTHON=python3.5 On Windows: .. code-block:: bat set PYTHON=C:\python35\python.exe && make test ...or: .. code-block:: bat make -p 35 test If you want to modify psutil and run a script on the fly which uses it do (on UNIX): .. code-block:: bash make test TSCRIPT=foo.py On Windows: .. code-block:: bat set TSCRIPT=foo.py && make test ==================== Adding a new feature ==================== Usually the files involved when adding a new functionality are: .. code-block:: bash psutil/__init__.py # main psutil namespace psutil/_ps{platform}.py # python platform wrapper psutil/_psutil_{platform}.c # C platform extension psutil/_psutil_{platform}.h # C header file psutil/tests/test_process|system.py # main test suite psutil/tests/test_{platform}.py # platform specific test suite Typical process occurring when adding a new functionality (API): - define the new function in ``psutil/__init__.py``. - write the platform specific implementation in ``psutil/_ps{platform}.py`` (e.g. ``psutil/_pslinux.py``). - if the change requires C, write the C implementation in ``psutil/_psutil_{platform}.c`` (e.g. ``psutil/_psutil_linux.c``). - write a generic test in ``psutil/tests/test_system.py`` or ``psutil/tests/test_process.py``. - if possible, write a platform specific test in ``psutil/tests/test_{platform}.py`` (e.g. ``test_linux.py``). This usually means testing the return value of the new feature against a system CLI tool. - update doc in ``doc/index.py``. - update ``HISTORY.rst``. - update ``README.rst`` (if necessary). - make a pull request. =================== Make a pull request =================== - fork psutil - create your feature branch (``git checkout -b my-new-feature``) - commit your changes (``git commit -am 'add some feature'``) - push to the branch (``git push origin my-new-feature``) - create a new pull request ====================== Continuous integration ====================== All of the services listed below are automatically run on ``git push``. Unit tests ---------- Tests are automatically run for every GIT push on **Linux**, **OSX** and **Windows** by using: - `Travis `_ (Linux, OSX) - `Appveyor `_ (Windows) Test files controlling these are `.travis.yml `_ and `appveyor.yml `_. Both services run psutil test suite against all supported python version (2.6 - 3.6).

It is useful mainly for **system monitoring**, **profiling and limiting process resources** and **management of running processes**. It implements many functionalities offered by UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. psutil currently supports the following platforms: - **Linux** - **Windows** - **OSX**, - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** ...both **32-bit** and **64-bit** architectures, with Python versions from **2.6 to 3.6**. `PyPy `__ is also known to work. ==================== Example applications ==================== +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/top-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/top.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ Also see `scripts directory `__ and `doc recipes `__. ===================== Projects using psutil ===================== At the time of writing psutil has roughly `2.9 milion downloads `__ per month and there are over `6000 open source projects `__ on github which depend from psutil.

It is useful mainly for **system monitoring**, **profiling and limiting process resources** and **management of running processes**. It implements many functionalities offered by UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. psutil currently supports the following platforms: - **Linux** - **Windows** - **OSX**, - **FreeBSD, OpenBSD**, **NetBSD** - **Sun Solaris** - **AIX** ...both **32-bit** and **64-bit** architectures, with Python versions from **2.6 to 3.6**. `PyPy `__ is also known to work. ==================== Example applications ==================== +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/top-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procinfo.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/top.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem-small.png | .. image:: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap-small.png | | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/procsmem.png | :target: https://github.com/giampaolo/psutil/blob/master/docs/_static/pmap.png | +------------------------------------------------------------------------------------------------+--------------------------------------------------------------------------------------------+ Also see `scripts directory `__ and `doc recipes `__. ===================== Projects using psutil ===================== At the time of writing psutil has roughly `2.9 milion downloads `__ per month and there are over `6000 open source projects `__ on github which depend from psutil.
