Ditto on OpenNMS.  Rock solid system and very fast.  It can be kind of a
bear to configure (XML configuration files and testing even simple changes
sometimes require you to restart the entire monitoring system which can
take a while), but once you get the thing set up right, it just works.

It does graphing as well, but I prefer to use Cacti for that.
