How to monitor nagios performance

[michaelli]

Hi support,

I use the nagiostats to generate a report for our nagios server

According to below report,

Total Service State Change: 0.000 / 79.610 / 0.685 %
Active Service Latency: 0.000 / 0.988 / 0.008 sec
Active Service Execution Time: 0.000 / 30.007 / 1.126 sec
Active Service State Change: 0.000 / 29.470 / 0.044 %

what is the meaning information between 0.000/ xx.xxx / 0.xxx %/sec?

Which row or value we should concern to prevent nagios hit performance issue.

Code: Select all

[root@ngonap01 nagios]# /usr/local/nagios/bin/nagiostats -c /usr/local/nagios/etc/nagios.cfg

Those values take the form of minimum / maximum / average. The biggest indicator (among these listed) of poor system performance is your average service execution time.

Hi tmcdonald,

Thanks for your reply. According to Active Service Execution Time: 0.000 / 30.007 / 1.126 sec. Can I easy to find out which services has long execution time?

What meaning for "Active Service Latency: 0.000 / 0.988 / 0.008 sec" and which value we should award to prevent any performance issue.

This is a handy little script that I've used before:

What meaning for "Active Service Latency: 0.000 / 0.988 / 0.008 sec"

This is the time between scheduling and execution. With a maximum of under 1 second and an average under 1/100th of a second you're in great shape.
