I have been chasing my tail trying to figure out why my RRD files were very sparsely populated, and I am realizing that my checks are falling behind of their scheduled times up to 3 times their set check interval. For example a service that should be checking every 5 minutes. In the example below, the time is 00:19:02, the last check was 00:10:30 and the next scheduled check time is 00:13:28. This means it is almost 6 minutes behind schedule and almost 9 minutes since the last check!
I find even if I shorten the check interval to say 3 minutes it still behaves about the same. The server has very low load and nagios is hardly working at all. (usually below 4% cpu) I haven't touch any of the tuning on this and from what I have read the default settings appear unthrottled. Is there any way to make it "work harder"? --Service information-- Last Updated: Sat Oct 23 00:19:02 UTC 2010 --Service State Information-- Current Status: OK (for 7d 16h 14m 46s) Status Information: CPU STATISTICS OK : user=0.12% system=0.00% iowait=0.00% idle=99.88% Performance Data: 0.12;0.00;0.00;99.88;80;90 Current Attempt: 1/3 (HARD state) >>> Last Check Time: 10-23-2010 00:10:30 <<<< Check Type: ACTIVE Check Latency / Duration: 612.633 / 2.052 seconds >>> Next Scheduled Check: 10-23-2010 00:13:28 <<< Last State Change: 10-15-2010 08:04:16 Last Notification: N/A (notification 0) Is This Service Flapping?
