Well it depends on what exactly you want to monitor. Network services,
host availability etc?

If yes then I would recommend Nagios - http://www.nagios.org/ - or
OpenNMS - http://www.opennms.org/ . There are also several front-ends
for Nagios either open-source or commercial (or both) from which I
would recommend Centreon - http://www.centreon.com/ - which is
open-source and has some commercial add-ons, mostly about reporting
and SLAs, and OP5 - http://www.op5.com/ - which is a great commercial
product (but they give you a fully functional trial that you can
test).

If you are interested in monitoring logs, especially if you have tons
of them, then I'd say Splunk is the right tool, although it's a bit
expensive. Once you learn how it works (and it wont take you long)
then you can mine almost any information from your logs. AFAIK there
is a free edition that will log up to 500MB per day so you can give it
a shot.

I haven't tried PacketTrap so I have no opinion about it.
