A Nagios plugin to check hardware health on Dell servers

check_openmanage is a plugin for Nagios which checks the hardware
health of Dell PowerEgde and PowerVault servers. It uses the Dell
OpenManage Server Administrator (OMSA) software to accomplish this
task. check_openmanage can be used with SNMP or NRPE, whichever suits
your needs and particular taste. The plugin checks the health of the
storage subsystem, power supplies, memory modules, temperature probes
etc., and gives an alert if any of the components are faulty or
operate outside normal parameters.
