After some initial troubles, I have managed to upgrade three sentinel appliances from 8.2 to 8.5, but I seem to be missing some services on the sentinel server.
Perhaps some of you out there can help me locate them?
My collector manager is trying to send event to the sentinel server on port 61616. It seems this should be an ActiveMQ instance, but nothing is currently running there and I don't see a clear service to start it?
Could someone with a functioning system (8.5 is possible, but I guess any 8.x version will do) check what is responding on that port and see if they can locate the service and/or package that is responsible?
I think I might save a current snapshot and momentarily revert to before OS upgrade to see if I can find the files there, but any help would be appreciated.
There might be other services that should be running but are not. This is the most obvious one from the logs, though.
