Changing/configuring CheckCommand "icinga"

Hi,

is the check for Icinga itself a script or is it included in the Icinga service?
I can only see one variable:

  • icinga_min_version
    Is it possible to change the default behavior of this check?
    If the remote Icinga instance is not connected the return value is UNKNOWN.
    If one does not know what is ongoing there maybe CRITICAL would be a state that fits better.

Best

I use the cluster-zone check for this and set it as parent of all services on the hosts with a Icinga2 agent.
