Hi, I want to trigger an alert when a value from a custom poller has changed.
Specifically this is to alert when the EIGRP neighbor count (cEigrpNbrCount) changes on Cisco routers. The value will vary by router, so I cannot use a 'not equal' to a set figure to trigger an alert. The 'has changed' comparison would be useful, but I understand that this only applies to a limited number of settings and will not work for my application.
I am not that good at SQL, but I am happy to experiment if someone can give me a starting point. Something like a comparison to the value returned by the previous poll should do it.
Thanks in advance for your help.
