So, I want the ability to monitor and alert for the ammount of EIGRP neighbors on more than 1 router. I have 3 routers(being load balanced) that service as tunnel endpoints. Tunnels aren't exactly reliable for monitoring, so i've chosen to monitor EIGRP relationships instead. So far, i've set up a universal device poller using OID 1.3.6.1.4.1.9.9.449.1.2.1.1.2 (cEigrpNbrCount) and assigned it to the 3 devices. I was able to create a chart in the NPM WebUI using 'Multiple Universal Device Pollers Chart' and telling it to view sum only for that poller.
Now....I want to set up email alerting on the sum of all EIGRP neighbors between the 3 devices, but i'm having issues. Here's what I currently have setup in advanced alerting:
The problem is, whenever I set the alert with those conditions, it will generate hundreds of email every minute with very small ammounts. Is there some better way I can be doing this? How do I accomplish this?
