I have been looking for a way to do this, off and on, for a while.
With the help of some of the great community folks, I have been able to build a UDP table that I can map out my site-2-site tunnels. Basically, I created a UDP to poll
OID 1.3.6.1.4.1.9.9.392.1.3.21.1.2
I can display this nicely on our website.

My problem is, how do we create an alert to trip if/when one of these tunnels drop off?
since I have already had to manually create a mapping table in the UDP alert to show meaning full detail, I expected that I would also have to have some effort into the alert.
I asked support for assistance, and they simply pointed out the "Custom Node Table Poller" and sent me on my way.
My issue is - when we are polling a table via SNMP using UDP - is there an way to create a trigger to alert when one goes down, AND make it human readable?
I know I can do something like "Row ID is equal to 14.57.56.46.49.50.57.46.50.52.50.46.496.55.49.258650113", but that does no good if you don't know what that means. It would be better as "Row ID is equal to 12.12.18.78" or even (the map I created in UDP) "Row ID is equal to Site_2_Site_Cityname" or something.
Does anyone have any suggestions?
