Check for normal and security updates via APT
|Distribution:||official part of Check_MK|
This check checks for available normal and security updates by trying
apt-get update or apt-get dist-upgrade without actually installing
packets. 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 plugin with asynchronous execution and at an interval with at
least one hour.
The check gets CRIT if there are security updates available.
It gets WARN, if there are other updates available. These two
states can be overriden via a WATO 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
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
One service will be created for each system where the mk_apt plugin is being installed and the command apt-get is present.
