I am just glad that we don't have to send up/down messages to our CEO.... He would think we can't keep anything running.... (or paper/toner loaded in a printer) :)

Hi Patrick,

if you think there is a problem with the machine running nagios i would monitor localhost too :-) Or another way to get information about the performance of the Nagios-host is to get load and memory values through snmp and create load and memusage graphs with mrtg or cacti for example. That's the way I take a look @ the performance of my linux hosts

Kind regards,

Dennis Hünseler

Subject: [Nagios-users] Critical Plugin Timed Out

Hi all,

I've been running Nagios 2.6 for about 6 months now, and every now and then we get critical pages about a machine being down, or at least Nagios can't connect to it. It causes the CEO to freak out and believe something is up with our network.

Do you need help?

To me, it seems like the box is getting stressed out during the tests and is causing the plugins to time out.

Here's some of the alerts from this morning:

The machine is a p4 2.4 ghz with 1gb ram.

I'm not sure how to troubleshoot this - any ideas? What can I provide you folks in order to help me out?

Thanks in advance.
