 I've been using the following tools for many network monitoring tasks 
 such as traffic analysis, statistics collection, triggers, alerts etc:

 Nagios - http://www.nagios.org
 Zabbix - http://www.zabbix.com
 Ntop   - http://www.ntop.org/news.php

 The last one is specially great for on-site network troubleshooting.
