I have it to go to critical whenever the uptime is below X minutes, and email out. Network tests such as ping, snmp or ssh availability might miss a quick box's trip down, but uptime will always catch a reload.

I have a fresh install of Debian stable (squeeze) with apt-get installed Webmin, ssh, apache2, and Nagios 3.2.1, nagiosql, and whatever dependencies. I am trying to setup monitoring of our core Cisco routers and switches. I have configured 2 services, ping and uptime. Ping works great of course but I can’t get a valid response from check_snmp for uptime. Here’s the command I’ve tried from the command line:
