I'm using something called 'spong' because it was around back
when I needed it, is written in perl, and has a plugin
structure and is fairly easy to add custom tests.  I'd
probably go with nagios if I were starting today, but
spong is still available and still works fine for simple
tests, a grid display of red/yellow/green status, and
notifications when value thresholds are crossed.
http://spong.sourceforge.net/ There is a demo screen at
http://spong.monsters.org/spong/www-spong  Note the
detail and history if you click the colored dots or
a host name.  It also has a concept of throttling the
number of notifications it sends in a certain amount
of time which turns out to be a good idea.

I also use cacti http://www.cacti.net/ for graphs of
bandwidth, cpu, and memory use.

However, the reason we need so many monitors is for
application-specific monitors for about 100 hosts
that we need to see in real time plus a few for
spong, cacti, and some network monitors.
