We've used Nagios very successfully.  We have hundreds of hosts and well 
over a thousand checks, so I'm guessing that we're probably a medium-ish 
installation.  The use of templating makes adding hosts and services 
quick and painless.  We've evaluated some of the other options already 
mentioned here: zabbix, opennms, zenoss, even mon, and big-brother and 
friends, and have always decided that nagios is the best product for our 
needs, as far as system monitoring goes. The initial learning curve is 
about medium compared to some, and once you've gotten over that hump, 
there just don't seem to be others. I've recommended Nagios to a few 
less-than-seasoned sysadmins who were able to take the templating 
concept and run with it.   We have also setup cacti for the snmp 
statistics keeping. Nagios does have performance data capabilities now, 
they feel sort of tacked on to me.  The folks over at 
http://www.centreon.com/ are working on an integrated user interface 
that includes statistics keeping using Nagios as the monitoring engine 
which looks as though there may be some promise, if I was starting over 
I'd definitely evaluate that.

I hope this is of some help in your review process.
