When I close Server Monitor, I get a pop-up with this message:
The action DLL is missing for the following monitors: [Core - Inventory Collector] on ... and it repeats this for every server.
I know how to fix this for other monitors, by configuring actions on the monitor or power template, but Core Inventory Collector doesn't have actions, so I'm not sure how to fix it here. This happened with 8.1, the first version I installed, and after I upgraded to 8.2.
