My Icinga System->Health Page shows Icinga by monitoring is currently Unknown with status “icinga is currently not up and running” The icinga2 process is up and running on the server, but I cannot seem to tell how the Icinga Web 2 Health page is supposed to pull the information about the running PIDs. It seems the monitoring stats.phtml page calls checkPefromance.php and RuntimeVariables.php, but I cannot find any logging to tell why these are not finding the running PIDs:
