We've been working with one of our end customers to setup a WAN alert suppression for each of their locations. We have each of their edge routers at each of their site locations as the dependency and the other devices at each location as the group so that they will only receive one alert rather than hundreds when a site goes down. We were trying to run a test with this yesterday to make sure that everything was working as intended, however, when our customer took down the two WAN interfaces, their Orion server only showed that all of those devices at that site had 100% packet loss and were in a warning state instead of down. We had the WAN links disconnected for at least 30 minutes with no change in results. My understanding is that if the Orion server is not able to reach a device via ICMP, it's supposed to mark it as down. Our customer recently changed their Orion server to version 12 so I'm not sure if something changed from version 11 to 12. Let me know what your thoughts are and as always, your assistance is greatly appreciated.
