Anybody know of an open source network monitoring project that I can use to monitor the status of a vpn tunnel. I have a client with 30 L2L VPN tunnels on a 5510 and would like to incorporate some monitoring for them.
 
I would say any SNMP capable monitoring software (like Nagios). I'm sure you can check the VPN status via SNMP on a cisco. I know I can on a Netscreen...
 
Currently I monitor VPN by having a syslog server in place.

The configuration is a linux server Fedora with syslog-ng, Mysql, and php-syslogng-mysql.

Currently this model lets me know when contractor / consultants vpn in. THe syslog message from the pix tells me When howlong and how much.

Syslog-ng allows you to forward messages by filtered criteria (ASA/pix syslog seq numbers or textual syntax inthe message, to either email or MYSQL.

php-syslogng-mysql is a web guis that allows easy access to the log enteries in to MYsql.

isntallation is simply Yu the components, stopping syslog on linux and starting syslog-ng as it's replacement.
