[nycbug-talk] favourite monitoring tools

[Dru]

I have a client who is torn between spending $1995 on a commercial 
monitoring package that only installs on Windows or an Open Source 
solution which will run on his FreeBSD servers. His requirements are SMS 
paging ability (a must) and the ability to pay for support or at least 
access to decent documentation. GUI interface that won't scare the other 
admins is also a bonus.

Looking through ports/net-mgmt shows that Nav looks promising on features
(though lean on documentation other than the mailing lists). Anyone using 
this product? http://metanav.ntnu.no/moin.cgi/

Experiences good/bad with Bigsister, Nagios and Zabbix also appreciated. 
The client needs to manage just over 100 systems, a mix of routers, switches 
and servers.
