Roland Kletzing Reported crashing bug: successfully opening /proc/PID/cmdline does not imply we can read it (PID died between open() and read()). Paul Wise Started the man page. Göran Uddeborg Reported that iotop was misbehaving with UTF-8 strings. Ryan Lovett Contributed a bugfix: flush the output in batch mode, so that a potential output file is updated. Martin Bammer Initial implementation of the --time and --quiet options. Piotr Engelking Reported that iotop's ioprio_get syscall detection was buggy on 32bit userspace on a x86_64 kernel. Gabriel Redner Reported a crash were iotop could open /proc/PID/status but not read it as the process disappeared by then. Jiri Olsa Wrote the support for python2.4 with the ctypes module. Philipp Thomas Reported that iotop produced wrong numbers in openSUSE 11.3. Jakub Wilk Contributed syscall numbers for getting and setting IO priority on armel and hppa architectures. Jeff Mahoney Contributed a fixed implementation of the taskstats parsing code. Florian Mickler Contributed a fixed implementation of the taskstats parsing code. Ka-Hing Cheung Contributed code to show custom thread names. Igor Bazhitov Contributed the differentiation between total and actual I/O. iotop-0.6/iotop.py0000750022136700116100000000045712150510102014743 0ustar chazaraineng00000000000000#!/usr/bin/python # iotop: Display I/O usage of processes in a top like UI # Copyright (c) 2007, 2008 Guillaume Chazarain # GPL version 2 or later # See iotop --help for some help import sys from iotop.ui import main try: main() except KeyboardInterrupt: pass sys.exit(0) iotop-0.6/.gitignore0000640022136700116100000000001612150510102015214 0ustar chazaraineng00000000000000*.pyc /build/ iotop-0.6/setup.cfg0000640022136700116100000000013612150510102015050 0ustar chazaraineng00000000000000[bdist_rpm] doc_files = ChangeLog COPYING NEWS README THANKS install_script = .install-rpm.sh iotop-0.6/ChangeLog0000640022136700116100000007164712150510420015023 0ustar chazaraineng000000000000002013-05-27 Guillaume Chazarain * NEWS: Document signature 2013-05-27 Guillaume Chazarain * release.sh: GPG sign all released files 2013-05-26 Guillaume Chazarain * NEWS, iotop/version.py: Version bump. 2013-05-26 Guillaume Chazarain * iotop/ui.py: Clean exit also on SIGTERM otherwise the terminal is unusable. 2013-05-26 Guillaume Chazarain * iotop/ui.py: Python3 can print UTF-8 to curses, python2 can't so let's handle both. 2013-05-26 Guillaume Chazarain * iotop/ui.py: Cleanly exit on SIGINT otherwise python3 will leave the terminal in an unusable state. 2013-05-26 Guillaume Chazarain * .install-rpm.sh: No need to make the RPM install script move bin/ to sbin/ now that setup.py installs to sbin/. 2013-05-26 Guillaume Chazarain * setup.py: Make setup.py install the iotop script in sbin/ instead of bin/. 2013-05-26 Guillaume Chazarain * iotop/ui.py: In some setup closing the xterm window only has the effect of deleting the pty. Then iotop would be busy looping reading on stdin. Instead we should detect the terminal deletion and exit. When this happens iotop receives (0, 25) as an event, which is (stdin, select.POLLIN|select.POLLERR|select.POLLHUP). Also, represent an empty even list as [] instead of 0, this is just cosmetic. 2013-02-04 Paul Wise * iotop/data.py, iotop/ioprio.py, iotop/ui.py, iotop/vmstat.py: Fix the FSF address embedded in a few files 2013-02-04 Paul Wise * sbin/iotop: Fix python3 compatibility for iotop when installed 2013-02-03 Guillaume Chazarain * README, iotop/data.py: Update python requirements 2013-02-03 Guillaume Chazarain * NEWS: Also advertise the move to sbin/ as it's significant 2013-02-03 Guillaume Chazarain * .install-rpm.sh: The RPM should also install to sbin. 2013-02-03 Guillaume Chazarain * bin/iotop, sbin/iotop: Moved to sbin. 2013-02-03 Guillaume Chazarain * .install-rpm.sh, MANIFEST.in: Finish man page renaming 2013-02-03 Guillaume Chazarain * NEWS, iotop/version.py: Version bump 2013-02-03 Guillaume Chazarain * NEWS, THANKS: Advertise the newly introduced differentiation between total and actual I/O. 2013-02-03 Guillaume Chazarain * iotop/ui.py: 80 cols 2012-10-10 Igor Bazhitov * iotop.8, iotop/data.py, iotop/ui.py: Add 'Actual' bandwidth stats to summary header 'Total' values in the summary header may look confusing to users. They represent actual kernel <-> disk I/O bandwidth, while individual values for processes/threads show process <-> kernel I/O bandwidth.

Rewrite check_if_valid() to is_monitored().

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.

At least the CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING, CONFIG_TASKSTATS and CONFIG_VM_EVENT_COUNTERS options need to be enabled in your Linux kernel build configuration. .PP iotop displays columns for the I/O bandwidth read and written by each process/thread during the sampling period. It also displays the percentage of time the thread/process spent while swapping in and while waiting on I/O. For each process, its I/O priority (class/level) is shown. .PP In addition, the total I/O bandwidth read and written during the sampling period is displayed at the top of the interface. \fBTotal DISK READ\fR and \fBTotal DISK WRITE\fR values represent total read and write bandwidth between processes and kernel threads on the one side and kernel block device subsystem on the other. While \fBActual DISK READ\fR and \fBActual DISK WRITE\fR values represent corresponding bandwidths for actual disk I/O between kernel block device subsystem and underlying hardware (HDD, SSD, etc.). Thus \fBTotal\fR and \fBActual\fR values may not be equal at any given moment of time due to data caching and I/O operations reordering that take place inside Linux kernel. .PP Use the left and right arrows to change the sorting, r to reverse the sorting order, o to toggle the \-\-only option, p to toggle the \-\-processes option, a to toggle the \-\-accumulated option, q to quit or i to change the priority of a thread or a process' thread(s). Any other key will force a refresh. .SH OPTIONS .TP \fB\-\-version\fR Show the version number and exit .TP \fB\-h\fR, \fB\-\-help\fR Show usage information and exit .TP \fB\-o\fR, \fB\-\-only\fR Only show processes or threads actually doing I/O, instead of showing all processes or threads. This can be dynamically toggled by pressing o. .TP \fB\-b\fR, \fB\-\-batch\fR Turn on non\-interactive mode. Useful for logging I/O usage over time. .TP \fB\-n\fR NUM, \fB\-\-iter\fR=\fINUM\fR Set the number of iterations before quitting (never quit by default). This is most useful in non\-interactive mode. .TP \fB\-d\fR SEC, \fB\-\-delay\fR=\fISEC\fR Set the delay between iterations in seconds (1 second by default). Accepts non-integer values such as 1.1 seconds. .TP \fB\-p\fR PID, \fB\-\-pid\fR=\fIPID\fR A list of processes/threads to monitor (all by default). .TP \fB\-u\fR USER, \fB\-\-user\fR=\fIUSER\fR A list of users to monitor (all by default) .TP \fB\-P\fR, \fB\-\-processes\fR Only show processes. Normally iotop shows all threads. .TP \fB\-a\fR, \fB\-\-accumulated\fR Show accumulated I/O instead of bandwidth. In this mode, iotop shows the amount of I/O processes have done since iotop started. .TP \fB\-k\fR, \fB\-\-kilobytes\fR Use kilobytes instead of a human friendly unit. This mode is useful when scripting the batch mode of iotop. Instead of choosing the most appropriate unit iotop will display all sizes in kilobytes. .TP \fB\-t\fR, \fB\-\-time\fR Add a timestamp on each line (implies \-\-batch). Each line will be prefixed by the current time. .TP \fB\-q\fR, \fB\-\-quiet\fR suppress some lines of header (implies \-\-batch). This option can be specified up to three times to remove header lines. .RS .PD 0 .TP .B \-q column names are only printed on the first iteration, .TP .B \-qq column names are never printed, .TP .B \-qqq the I/O summary is never printed. .PD 1 .RE .SH SEE ALSO .BR ionice (1), .BR top (1), .BR vmstat (1), .BR atop (1), .BR htop (1) .SH AUTHOR iotop was written by Guillaume Chazarain. .PP This manual page was started by Paul Wise for the Debian project and is placed in the public domain. iotop-0.6/README0000640022136700116100000000121112150510102014102 0ustar chazaraineng00000000000000Iotop is a Python program with a top like UI used to show of behalf of which process is the I/O going on. It requires Python >= 2.7 and a Linux kernel >= 2.6.20 with the CONFIG_TASK_DELAY_ACCT CONFIG_TASKSTATS, CONFIG_TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS options on. To run a local version of iotop: $ ./iotop.py The documentation is available in the man page: $ man ./iotop.8 To install iotop, you should use a package provided by your distribution. If you really want to install this version of iotop on your system, do (as root): # ./setup.py install -- Guillaume Chazarain http://guichaz.free.fr/iotop iotop-0.6/iotop/0000750022136700116100000000000012150510420014363 5ustar chazaraineng00000000000000iotop-0.6/iotop/ui.py0000640022136700116100000005625712150510102015367 0ustar chazaraineng00000000000000# This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
