Passive Monitoring - some trouble
Posted: Tue Aug 17, 2010 9:05 am
OK, so my dept wants to implement an agent-based passive monitoring solution with Nagios that monitors several services and system info (mem usage, cpu usage, etc) per server. I've been trying to do this for a couple weeks now with no luck. What I've managed so far is a workstation sending info to the NSCA on the Nagios server via NSClient++.
First thing's first, Nagios doesn't always alarm when there's a warning or critical state reported when it's set to report on those states. I've been watching the NSClient++ /test mode and it's been sending critical warnings on this machine where I've got a drive nearly full but sometimes I see the alarm, sometimes I don't. I've even got flapping detection turned off. I don't know what's causing this.
More importantly, is there a way to list the services for passive monitoring like you can with active monitoring or does the status just go in the status field for a passively monitored host?
