VPN tunnel monitoring

Anand Narayana · ‎08-16-2008

I have multiple vpn tunnels configured, I wanted to configure a monitoring in such a way that, If one particular vpn tunnel is down, I should be alerted or something like whatsupgold software. All I should be knowing the information what time the tunnel went down & came back up.

Anand,

I am not aware of any specific software, I personally use SNMP. I log all traps in my syslog server, then filter per messgage type based on:-

Device name, IP address, syslog ID, key words

Then in my syslog server I have a script that alerts me to the specific alerts I want to know about.

I use Linux, and syslog-ng.

Advantage of VPNTTG over other SNMP based monitoring software’s is following: Other (commonly used) software’s are working with static OID numbers, i.e. whenever tunnel disconnects and reconnects, it gets assigned a new OID number. This means that the historical data, gathered on the connection, is lost each time. However, VPNTTG works with VPN peer’s IP address and it stores for each VPN tunnel historical monitoring data into the SQL server and into the RRD (Round Robin Database) file.
