APT: Normal and Security Updates

Included in	All Checkmk editions
Source Code License	Open Source
Supported Agents	Linux

This check checks for available normal and security updates by trying apt-get upgrade or apt-get dist-upgrade without actually installing packages.

It works on Debian and Ubuntu. You need to deploy the plugin mk_apt in order for the check to work. It is recommended to install this plug-in with asynchronous execution and at an interval with at least one hour.

The service goes CRIT if there are security updates available. It goes WARN, if there are other updates available.

These two states can be configured via a Setup rule.

If updates are performed on a host the WARN and CRIT state will remain until the next check interval. To invalidate the cached data and to trigger the check execution immediately, you can run the command:

touch -t 197012081200 /var/lib/check_mk_agent/cache/*mk_apt.cache

If you don't want to invalidate the cache manually you can copy the apt hook under ~/share/doc/check_mk/treasures/mk_apt_hook to /etc/apt/apt.conf.d/98mk-apt.

Discovery

One service is created for each system where the {mk_apt} plug-in is being installed and the command {apt-get} is present.
