This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 6. Often, you can also type `make uninstall' to remove the installed files again. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *Note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. downtimed-0.6/downtimes.c0000644000175000017500000001624012174756475012474 00000000000000/*- * Copyright (c) 2009-2013 EPIPE Communications.

If the daemon is killed with a signal associated with a normal system shutdown procedure, it will record the shutdown time on the disk. .PP When the daemon is restarted during the next boot process, it will report how long the system was down and whether it was properly shut down or crashed. The downtime report is output to the system log or to a specified log file. Also a record is appended to the downtime database. .SH OPTIONS .TP .B \-D Do not create nor update the downtime database. .TP .B \-d \fIdatadir\fR The directory where the time stamp files as well as the downtime database are located. The default directory is determined at compile time. .TP .B \-f \fItimefmt\fR Specify the time and date format to use when reporting using .BR strftime (3) syntax. The default is "%F %T". .TP .B \-l \fIlog\fR Logging destination. If the argument contains a slash (/) it is interpreted to be a path name to a log file, which will be created if it does not exist already. Otherwise it is interpreted as a syslog facility name. The default logging destination is "daemon" which means that the messages are written to syslog with the daemon facility code. .TP .B \-p \fIpidfile\fR The location of the file which keeps track of the process ID of the running daemon process. The system default location is determined at compile time. .TP .B \-S Normally .BR fsync (2) is performed after each update of the time stamp. This option disables the .BR fsync (2). It reduces the load on the disk system but makes the downtime measurement less reliable. .TP .B \-s \fIsleep\fR Defines how long to sleep between each update of the on\-disk time stamp file. More frequent updates result in more accurate downtime reporting in the case of a system crash. Less frequent updates decrease the amount of disk writes performed. The default is to sleep 15 seconds between each update. If you are using a flash memory based SSD or other disk which has limited amount of write cycles per block, it might be a good idea to set the sleep time to a higher value to prolong the lifetime of the storage device. .TP .B \-v Display the program version number, copyright message and the default settings. .SH SIGNALS .TP .B SIGHUP Close and re-open the output log. Use in case you want to rotate the log file. .TP .B SIGTERM and SIGINT Terminate gracefully. These signals signify that a graceful system shutdown is in process. .SH EXIT STATUS The daemon exits 0 on success, and >0 if an error occurs. .SH SEE ALSO .\".BR downtime (1), .BR downtimes (1), .BR syslog.conf (5), .ie !d pdfhref \ http://dist.epipe.com/downtimed/ .el \ .pdfhref W http://dist.epipe.com/downtimed/ .SH BUGS The reporting accuracy in case of a system crash depends on how often the time stamp is updated. .PP Finding out the system startup time is very operating system specific. If the program does not have specific code to support your operating system, it assumes that the system started when the daemon started. .PP Reporting is inaccurate if the system clock changes during system downtime or startup process.

It can be used to specify the desired time and date format for reporting. The default remains "%F %T". - Implemented -u command line option for downtimes(1) for reporting times in UTC. Analogous to "date -u". - GNU/Hurd compatibility fixes contributed by Mats Erik Andersson. - FreeBSD 9 compatibility fix by Douglas Thrift. version 0.5 released 2011-03-02 - Fixed a bug which prevented creation of the required time stamp files in case command line option -S was set. - Determine boot time on some SVR4 systems such as Solaris. - Compatibility for systems which do not have flock() but have lockf(), such as Solaris. - Compatibility for systems without facilitynames in , such as Solaris. - Compatibility daemon(3) function for OSes which do not have it, such as Solaris. - Compatibility for systems which lack futimes(3) function, such as Solaris. - Log an error message if system boot time can not be determined. - Remove dependency on be64toh(3) and betoh64(3). Or betoh64(3) and htobe64(3). Or OSSwapBigToHostInt64(3) and OSSwapHostToBigInt64(3). The code became a mess because 64 bit byte swapping is not standardized. Also some commonly used GNU/Linux distributions such as RHEL/CentOS 5.5 have such an old glibc that it does not include any of these functions. Now we just implement our own byte swapping macro and ignore whatever is or is not available from the system. This improves portability on many platforms, for example on Red Hat (RHEL) and Solaris. - Improve README documentation regarding startup scripts. - Example startup scripts have been moved to the "startup-scripts" sub-directory. - openSUSE startup script by Federico Lucifredi . - OpenBSD compatibility improvements. - Debian GNU/kFreeBSD compatibility improvements. - Use volatile sig_atomic_t if available for flags set by signal handlers. - Other minor fixes. version 0.4 released 2010-12-25 - Do not create the data directory /var/{db,lib}/downtimed in the daemon. It should be created by the system administrator or the package maintainer instead. Problem reported by Mats Erik Andersson . - OpenBSD support and other minor fixes by Mats Erik Andersson . - Debian GNU/kFreeBSD support by Mats Erik Andersson . - Change backwards lseek(2) to forward lseek(2) as the backwards seek fails on some platforms, by Mats Erik Andersson . - Other minor fixes. version 0.3 released 2010-10-26 - Mac OS X support by Henrik Ahlgren - Fix man page rendering on various OSes such as FreeBSD (we were using non-standard .SY, .YS and .OP macros) [this has no effect on GNU/Linux, no need to upgrade] - Fix printf format string to avoid compiler warnings version 0.2 released 2010-09-22 - implemented downtimes(1) command for displaying the contents of the downtime database in human readable format - implemented downtime database in the downtimed(8) daemon - moved the location of data files from /var/lib/misc/downtimed/ to /var/lib/downtimed/ on Linux. - the default sleep time between time stamp updates is now 15 seconds instead of 5 as previously - minor documentation improvements version 0.1 released 2010-05-22 - initial release /* eof */ downtimed-0.6/LICENSE0000644000175000017500000000274612174756501011320 00000000000000Copyright (c) 2009-2013 EPIPE Communications.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

All rights reserved. This software is licensed under the terms and conditions of the FreeBSD License which is also known as the Simplified BSD License. You should have received a copy of that license along with this software. Software web site: http://dist.epipe.com/downtimed/ Development version is available at Launchpad: https://launchpad.net/downtimed Main development branch of downtimed is available with Bazaar VCS: bzr branch lp:downtimed Author's e-mail address for reporting bugs, sending contributions etc: opensource@epipe.com Portability =========== Currently supported operating systems: - Recent versions of FreeBSD, NetBSD and OpenBSD - Modern GNU/Linux distributions - Mac OS X/Darwin - GNU/Hurd - Solaris / OpenSolaris / OpenIndiana The software probably works on other modern *BSD variants with zero or little modifications. The only really non-portable part of the program is the getboottime() function which uses an operating system specific interface for finding the exact moment when the kernel started again. The function can be easily altered to add support for additional operating systems. The author would appreciate receiving any such patches to be integrated in the main distribution. Also for the sake of convenience the program uses some functions which are available only in modern operating systems. These include for example asprintf(3), vasprintf(3), snprintf(3), err(3) and errx(3). History ======= The author of this software had a Xen based virtual private server (VPS) running FreeBSD operating system. Occasionally the owner of the physical non-virtual machine would turn off the VPS to do some system administration tasks on the host operating system, which the author did not have access to. The author wanted to have some sort of record of when, why and how long the VPS had been down. The standard FreeBSD system did not provide such a facility. After some looking around it seemed that there was only programs for monitoring uptime but not downtime. Also most of these programs were complicated and were intended to be run on a remote host and thus they would be actually monitoring the system availability through the network instead of the actual downtime of the FreeBSD operating system running on the VPS. Also they would require an another server for monitoring the primary server. Therefore downtimed was needed. Features ======== downtimed was made to monitor operating system downtime, shutdowns and crashes on the monitored host itself and to keep a record of such events. downtimed(8) is a daemon process which is intended to be started automatically from system boot scripts every time when the operating system of a server starts. First the daemon logs its findings about the previous downtime to a specified logging destination as well as in a database file which can be displayed with downtimes(1) command. Thereafter the downtimed(8) daemon just keeps waiting in the background and periodically updates a time stamp file on the disk. The time stamp is used to determine the approximate time when the system was last up and running. In case of a graceful system shutdown it records a stamp to another file on the disk. These files are used for reporting the next time the daemon starts. downtimes(1) is a command-line tool which can be used to inspect previous downtime records recorded in the downtime database file. Installation ============ Installation should be preferably done through a port or a package which is tailored to your specific operating system. If one does not exist or if you yourself are making such a port or a package, the basic GNU autotools based installation should be as follows: ./configure make make install The above does NOT install any startup scripts which are REQUIRED for proper function of downtimed. See the following chapter. The program also needs a persistent data directory for the time stamp and the downtime database files. It should be created on *BSD and MacOS X as follows: mkdir /var/db/downtimed ...or on GNU/Linux, Debian GNU/kFreeBSD, GNU/Hurd or Solaris as follows: mkdir /var/lib/downtimed Note that you can determine the default data directory location on your system by issuing "downtimed -v" command or you can specify a different directory with the "-d" option. Set the directory permissions as appropriate in your environment. If you are installing a port or package tailored for your system, this step is most likely taken care for you automatically. Startup scripts =============== It seems that every different operating system and distribution has invented their own ways of starting system daemons during the boot process. That is a major pain in the ass. The downtimed distribution includes the following operating system and distribution specific startup script samples. They are located in the "startup-scripts" directory. It is assumed that system administrators or port/package maintainers will implement and configure the required startup scripts. Arch Linux ---------- Arch Linux startup script is included as archlinux-startup.sh. It should be installed as /etc/rc.d/downtimed and added to the DAEMONS setting in /etc/rc.conf. Debian ------ A startup script for GNU/Debian and related distributions is included as debian-startup.sh. It should be installed as /etc/init.d/downtimed. Running the command "update-rc.d downtimed defaults" enables starting the service at the system startup. FreeBSD ------- A sample startup script for FreeBSD is included as freebsd-startup.sh. It should be installed as /usr/local/etc/rc.d/downtimed. Add: downtimed_enable="YES" ...in one of the following files to enable boot time startup: /etc/rc.conf /etc/rc.conf.local /etc/rc.conf.d/downtimed Add the following if you want to configure downtimed(8) command line options: downtimed_flags="" Mac OS X -------- Mac OS X/Darwin launchd(8) configuration file com.epipe.downtimed.plist is also included. This file should be installed to /Library/LaunchDaemons. OpenIndiana / OpenSolaris / Solaris ----------------------------------- SMF (Service Management Facility) manifest for OpenIndiana, OpenSolaris and Solaris 10 & 11 is in downtimed.smf.xml. It is not usable on Solaris 9 and older as they need a SysV style init script instead. openSUSE -------- A startup script for openSUSE is included as opensuse-startup.sh. It should be installed as /etc/init.d/downtimed. Running the command "innserv /etc/init.d/downtimed" enables starting the service at the system startup. Red Hat based distributions (RHEL, Fedora, SL, Oracle, CentOS, etc.) -------------------------------------------------------------------- A startup script for Red Hat related distributions is included as redhat-startup.sh. It should be installed as /etc/rc.d/init.d/downtimed. Running the command "chkconfig --add downtimed" enables starting the service at the system startup. Ubuntu ------ A startup script for GNU/Linux distributions using upstart(8) to bring up system daemons, such as the Ubuntu distribution, is included in upstart-startup.conf. It should be installed as /etc/init/downtimed.conf. These startup scripts are not installed by default. This program is not really useful unless there is a proper startup script in place. Refer to your operating system or distribution manual on how to create and manage daemon startup scripts. Usage documentation =================== Have a look at downtimed(8) manual page: man downtimed ... as well as the downtimes(1) manual page: man downtimes Alternatively you can find a PDF version of the manual pages at: http://dist.epipe.com/downtimed/ Contributions ============= If you port this software to a new operating system, find bugs or implement new features, it would be nice if you could send your patches to the author either through Launchpad or by e-mail. See the top of this document for contact information.
