        # check_systemd
        
        `check_systemd` is a [Nagios](https://www.nagios.org) /
        [Icinga](https://icinga.com) monitoring plugin to check
        [systemd](https://systemd.io). This Python script will report a degraded
        system to your monitoring solution. It can also be used to monitor
        individual systemd services (with the `-u, --unit` parameter) and timers
        units (with the `-t, --dead-timers` parameter). The only dependency the
        plugin needs is the Python library
        [nagiosplugin](https://nagiosplugin.readthedocs.io/en/stable).

        optional arguments:
          -h, --help            show this help message and exit
          -u UNIT, --unit UNIT  Name of the systemd unit that is being tested.
          -e UNIT, --exclude UNIT
                                Exclude a systemd unit from the checks. This option can
                                be applied multiple times, for example: -e mnt-
                                data.mount -e task.service. Regular expressions can be
                                used to exclude multiple units at once, for example: -e
                                'user@\d+\.service'. For more informations see the
                                Python documentation about regular expressions
                                (https://docs.python.org/3/library/re.html).
          -n, --no-startup-time
                                Don’t check the startup time. Using this option the
                                options '-w, --warning' and '-c, --critical' have no
                                effect. Performance data about the startup time is
                                collected, but no critical, warning etc. states are
                                triggered.
          -w SECONDS, --warning SECONDS
                                Startup time in seconds to result in a warning status.
                                Thedefault is 60 seconds.
          -c SECONDS, --critical SECONDS
                                Startup time in seconds to result in a critical status.
                                Thedefault is 120 seconds.
          -t, --dead-timers     Detect dead / inactive timers. See the corresponding
                                options '-W, --dead-timer-warning' and '-C, --dead-
                                timers-critical'. Dead timers are detected by parsing
                                the output of 'systemctl list-timers'. Dead timer rows
                                displaying 'n/a' in the NEXT and LEFTcolumns and the
                                time span in the column PASSED exceeds the values
                                specified with the options '-W, --dead-timer-warning'
                                and '-C, --dead-timers-critical'.
          -W SECONDS, --dead-timers-warning SECONDS
                                Time ago in seconds for dead / inactive timers to
                                trigger a warning state (by default 6 days).
          -C SECONDS, --dead-timers-critical SECONDS
                                Time ago in seconds for dead / inactive timers to
                                trigger a critical state (by default 7 days).
          -i, --ignore-inactive-state
                                Ignore an inactive state on a specific unit. Oneshot
                                services for example are only active while running and
                                not enabled. The rest of the time they are inactive.
                                This option has only an affect if it is used with the
                                option -u.
          -v, --verbose         Increase output verbosity (use up to 3 times).
          -V, --version         show program's version number and exit
        
        Performance data:
          - count_units
          - startup_time
          - units_activating
          - units_active
          - units_failed
          - units_inactive

        ## Behind the scenes
        
        To detect failed units this monitoring script runs:
        
        ```sh
        systemctl list-units --all
        ```
        
        To get the startup time it executes:
        
        ```sh
        systemd-analyze
        ```
        
        To check a specific  unit (`-u, --unit`) this command is executed:
        
        ```sh
        systemctl is-active <unit-name>
        ```
        
        To find dead timers this plugin launches:
        
        ```sh
        systemctl list-timers --all
        ```
        
        To learn how `systemd` produces the text output on the command line, it
        is worthwhile to take a look at  `systemd`’s source
        code. Files relevant for text output are:
        [basic/time-util.c](https://github.com/systemd/systemd/blob/main/src/basic/time-util.c),
        [analyze/analyze.c](https://github.com/systemd/systemd/blob/main/src/analyze/analyze.c).
        
        ## Testing
        
        ```
        pyenv install 3.6.12
        pyenv install 3.7.9
        pyenv local 3.6.12 3.7.9
        pip3 install tox
        tox
        ```
        
        ## Deploying
        
        Edit the version number in check_systemd.py (without `v`). Use the `-s`
        option to sign the tag (required for the Debian package).
        
        ```
        git tag -s v2.0.11
        git push --tags
        ```
