One last point, and another warning to add (which I discovered while writing this piece). Not all events and not all warnings show up via IPMI. We discovered that one machine had decided that a DIMM was creating too many errors and had taken it out of service, but this was not reported by IPMI – we found it in the logs and via a Unix command. Just for the record it was a Sun and the Solaris command was "fmadm faulty". There's always something...

Presumably Nagios is SNMP aware - both operating on received traps, and also sending them - so that it can be used to monitor infrastructure (switches, routers etc) and also as part of a distributed management system, reporting to a manager of managers?
