Check_MK: apt update

Check for normal and security updates via APT

Distribution:	official part of Check_MK
License:	GPL
Supported Agents:	Linux

This check checks for available normal and security updates by trying apt-get update or apt-get dist-upgradewithout 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 critical if there are security updates available. It gets warning, if there are other updates available. These two states can be overriden via a WATO rule. 

Discovery

One service will be created for each system where the mk_apt plugin is being installed and the command apt-get is present.
