Is there a good report to show the call manager stats for each node similar to the VOIP view?
What kind of UCM reports are you looking for? Something like these screenshots of a UC app?

What app is that? Nice stuff!
Yes what is that App?
It's made by a Cisco development partner, Variphy (pronounced like verify) - if you want, you can google them and ask them for a free software trial. I know they work with Call Managers (from CCM 4.x up to UCM 8.x), Unity, and Unity Connection. Also, I'm pretty sure the software comes with its own tomcat web server (so you don't have to install a client) and you can run it on a laptop, desktop, server, or in VM.
