We have a fully functional Nagios systems that has been in place for over a year... all of the sudden we are getting random " No output available from command... " on our checks of windows servers.
They are random as they come and go and they are never the same servers nor the same host. If I force a new check of all services the service getting the error will report "OK" and other services will get the error.
Has anyone experienced this? Any solutions?
