I am facing issue with the “check_file_age” pluggin, it working fine when i am executing it locally on the host. For reference,please find the screenshot from the local host;
You currently are executing the command on the node that is shown as “check source”.
If you want it to be executed on the remote host (the configured host object) you will need to configure the check to be either executed via check_by_ssh or install the Icinga Agent on the remote host that takes care of the check execution.
