We have been using JFFNMS (http://www.jffnms.org) for the last 2 years and works just great. You can monitor almost anything you'd like to via SNMP (we currently use it to graph Traffic, Drops, Input Errors, RTT, Packet Loss, CPU, Memory, Temperature, TCP Connections, BGP, etc). And has email/paging capabilities. Try it out and let me know.

We are currently using WhatsUp Gold, and would like to move to something more flexible (and not running on a Windows platform). Something that has email/paging capabilities, and can process SNMP traps would be a plus for us as well. Recommendations? Thanks.
