I am having performance issues on our Nagios 3.0.2 box. I have 340 hosts and 515 Services being monitored. I noticed this past weekend that Nagios is not paging out and is not catching server reboots. I moved off all of our routers and switch off of this Nagios server whiched dropped the number of hosts to 225. I am seeing some improvement but not that much. We are still not getting alerts on VM server reboots.
Here is my process info:
Actively Checked: Time Frame Hosts Checked
<= 1 minute: 132 (58.7%)
<= 5 minutes: 214 (95.1%)
<= 15 minutes: 225 (100.0%)
<= 1 hour: 225 (100.0%)
Since program start: 225 (100.0%)
Services Actively Checked: Time Frame Services Checked
<= 1 minute: 169 (32.8%)
<= 5 minutes: 516 (100.0%)
<= 15 minutes: 516 (100.0%)
<= 1 hour: 516 (100.0%)
Since program start: 516 (100.0%)
We need to be alerted on servers rebooting.
I have changed my setting to the following
Your config is set for
But this isn’t helping. If anyone can offer some suggestions I would apprieciate it. I do not want to have to set up another server.
