We are running NPM 9.5.1 and have installed the Orion management pack on our SCOM server. The problem I am running into is every time maintenance is performed on the NPM server, SCOM shots out an alert for every single interface and node going down. Additionally, there are a number of concerns I have with when these alerts are being recieved by SCOM. We recently rebooted the NPM server and prior to doing so we put all network elements into maintenance mode (on SCOM). This reboot took place at 4:30 PM. We did not see alerts in SCOM until 7:55 PM and that was only half of the elements. The rest came through at 8:00 AM the next morning.
We have Adavanced alerts and basic alerts turned off for all intensive purposes. I spoke with support on several occasions related to these problems, but I can't seem to get a clear understanding of how NPM is notifying SCOM of problems.
NPM, our DB, and SCOM are all on different servers
