I have Network Performance Monitor installed in my network. I monitor everything in my local network, servers, routers, switches and the like. I also monitor my remote sites via an MPLS network that we take care of as well.
The problem that I am seeing is that a few times a day I will get a notification letting me know that 'This Server has come online' or 'This Switch has come online'. The odd thing is that I never got a notification that this node had gone offline and checking the statistics on the node it doesn't show any downtime either. I check the logs of the node and it didn't reboot or go offline.
The only thing I can add that might help is that I recently moved the NPM installation from one server to another. The only nodes that I get these notifications from are on the WAN, nothing internally. I have tried to increase timeouts and the such, but I still get them.
Does anyone know what is causing the stray notification, and more importantly, how do I stop it?
