[olug] Open source monitoring system?

[Curtis LaMasters]

The number of servers and services that you are able to monitor with
nagios would also depend on the number of checks it has to do actively
(query).  As with most of the other solutions mentioned, most servers
can have an agent to push the data to nagios causing the overall load
on the server to drop.  NSCA is the protocol that nagios supports for
this type of communication.

I WAS running Nagios 2 on an HP 6120 laptop at my desk with 250+ hosts and around 1000 services, until I hosed it.  8)  It only had 1GB of ram and a single core intel proc...just as a reference.
