Nagios Support Forum

In syslog, no memory errors or anomaly messages appeared. Plugins means, I am using only normal nagios plugins and few custom bash scripts as plugins. Any known issues with any plugins? If it was a plugin, then we should be able to see that in nagios logs and after that plugin check, the nagios serv...

Script detects Nagios shutdown error in logs. So by that time error is detected, plugin will be stopped and nagios will be down, if in case a plugin is causing the issue. However, I have enabled nagios alerts for processes and memory usage for nagios server itself. It has graphs available. These gra...

The issue occurred again yesterday. "check_for_updates=0" is still set as is, which didn't solve the issue. Any solution for this?

Logs shows below error and since then until the time server was rebooted, no alerts came nor any logs. nagios.log: [Wed Mar 27 22:20:35 2019] SERVICE ALERT: afpres01;Ping;OK;HARD;2;PING OK - Packet loss = 0%, RTA = 2.82 ms [Wed Mar ...

I installed nagiosgraph for generating Graphs. However, for all Windows servers- SERVICESTATE plugins, the graphs shows "No data available". These are the plugins by default with nsclient++. check_command check_nt!SERVICESTATE!-d SHOWALL -l CssInterfaceCenter For CPU and disk related plugi...

I reinstalled and reinstalled nagios client multiple times. Copied files from working clients to the non working client and finally somehow it started working.

Still the same
