Hi,
I have just managed to poll s2s vpn stats from ASA. However can't get my head round creating an alert for when a VPN connection drops.
can you please help me with this?
I am using NPM 11.5.1 and ncm 7.4.1.
thanks in advance.

Hi Qasim
I guess that either you are using a custom poller (OID) to monitor VPN status or you are monitoring the tunnel as an interface. In case you are using a custom poller, normally you get the status based on a number, ie 0 = down, 1 = up (this may be different in your OID). If this is the case, just create an alert based on custom node table poller with two statements:
1. Unique name = name of the custom poller
2. current numeric value = (here you enter the number that means that the VPN is down)
If you are monitoring the VPN based like it was an interface, what you can do is monitor the interface traffic and when it is 0 for 1 hour (for example) that could mean that the VPN is down. In this case, this alert would require some fine tuning in order to configure the optimal values. Maybe it requires more than one hour, maybe it requires to monitor Rx and Tx being less than 1kbps....In this case the alert would be for interfaces with two statements (or more in case you need so):
1. Full name = name of the interface
2. Group (OR conditions)
2.1. Received bps = 0
2.2. Transmitted bps = 0
Conditions must exist for more than 60 minutes.
