Notice Unknown on nagios !

[ky_pim]

Hi all,

Sorry, my english is very poor.

I have a nagios core server 4.0.8 version. Sometime, some service notified UNKNOWN status (1.png), but then it's back to normal status (2.png).

Please advise and help me handle this problem.

Thanks all.

Most likely the plugin you are using is timing out and hence generating a unknown status.

Increase the timeout of the plugin in your command or service definition.

If you need help with this, you'll need to post your host, service and command definitions.

You will want to modify the python script to have a longer timeout as @Box293 mentioned, or debug why that variable is happening. This isn't a standard plugin, so we're limited on the help we can provide for it.
