I agree that Big Brother and Nagios are good solutions, and have heard
that munin is nice as well.  If you want really detailed information along
with very pretty graphs, you can run snmpd on the servers and report the
results with rrdTool.  The learning curve is a bit steep, but the results
are very nice.  Also, many servers with remote access cards support IPMI
and you can get good information from the card about all the internal
components of the server, such as motherboard power, temperature, fan
speed, etc.  Big Brother has plugins for these kinds of things and I am
sure Nagios has an IPMI plugin as well.
