I am trying to monitor VPN tunnels up/down status. Can anyone tell me the best way to do this with the Solarwinds Product? We are trying to avoid just pinging a server on the far side of the VPN tunnel as it is a third party device and we do not particularly care if their server is up and running, only that the tunnel is up. I already have the Universal Pollers for the Cisco ASA that tells us the number of active tunnels, current connections, and the number of sessions.
If using the cikeGlobalActiveTunnels OID is a good way to monitor active VPN's, how can I configure alerting if a critical VPN is no longer active? The issue here is that not all of the VPN sessions are critical nor are they up all the time, so how can I differentiate the critical VPNs that should be up 24/7 from the ones that are only used periodically throughout the day?
I am aware of using the IP SLA Monitor option to ping an IP on the other end as well. I am thinking that this may be my best bet, but I wanted to pose this question to the community just to be sure.
Thanks.
