I've generally found Nagios to be very good for service
monitoring and alerting, but scaling can be painful without some sort of
addon for config management. The distributed monitoring is available,
but feels kindof hacky to me.

Cacti is good for graphing SNMP data, but I find it to be a
major pain to get it to graph anything that it doesn't have
templates for, and crafting new templates tends to be headache
inducing for me. That could just be my incomplete understanding
of SNMP MIBs though.

For general purpose graphing, I've been tending toward Munin. The
plugin API is very simple, so it's easy to write new ones in pretty much
any language you like. The UI isn't as polished as Cacti though.

OpenNMS looks interesting to me, I think I'll have to try it out
sometime when I get spare cycles...
