We have at least one alert set that since upgrading to 10 are no longer activating.
The setups have not changed, I have verified the configs are valid, and I can test fire the alerts just fine and receive the messages. It acts like the part of NPM that monitors the stats isnt seeing the correct data.
The alerts in question detect % utilization on a backup T1 to alert us that the primary fiber line has gone down. when utilization hits 7%, it pages us to let us know data is flowing across the wire. when it drops below 3% it sends another alert to notify us that it has returned to an idle state. It worked fine for months prior to upgrading.
While writing this post, I did a little more research and ran some tests. I setup an alert to email when an interface goes down, and selected one that is currently down. after waiting a few minutes it is still not alerting us to an interface down condition that is present on the network summary page.
Any ideas where to check first?
