check_os_release

This is a Nagios/Icinga plugin to check if the currently installed operating system version is outdated. It checks:

  • whether the installed version is about to reach end-of-life (see --eolWarningDays, --eolCriticalDays, --eolIgnore parameters),
  • or whether a newer release is available (see --releaseWarningDays, --releaseCriticalDays, --releaseIgnore parameters).

Currently only Debian and Ubuntu are supported.

Information about releases and end-of-life dates is retrieved from https://salsa.debian.org/debian/distro-info-data/ or (if --localDID is specified) from the /usr/share/distro-info directory, which is provided by the distro-info-data package.

Requirements

  • Python 3
  • internet access (to download the latest release data); or a local up-to-date installation of distro-info-data package (specify --localDID parameter to use this)

Usage

usage: check_os_release [-h] [-v] [--eolWarningDays DAYS]
                        [--eolCriticalDays DAYS] [--eolIgnore]
                        [--releaseWarningDays DAYS]
                        [--releaseCriticalDays DAYS] [--releaseIgnore] [--lts]
                        [--server] [--cacheDir CACHEDIR]
                        [--cacheExpiration DAYS] [--localDID]
