We're currently trying to configure monitoring of Call Manager, Unity Connection, UCCX and CUPS. We are running into 3 issues and I thought I'd lump them into one topic but I can open 3 separate discussions if needed.
1) This works on my 11.5 lab. I don't recall having to download a WSDL first to make it work, but it's likely I did that as a first step anyway on first testing it. Perhaps check under Unity Connection Serviceability/Tools/Service Management and see if there are any suspect services not enabled (e.g. Connection Realtime Monitoring APIs).
