Are there any Asterisk Monitoring Tools out there?

Good Day everyone,
While I really like the FOP for small installations, I have a rather large installation (600 users) that I would like to monitor real time.
There are several ways I could do this but what I am most interested in is a console that shows registered stations and trunks along with any alerts that come out of the system. I found Glass Console and that would be perfect for what I need but it is way too buggy and it looks like no development has been done to it in about 4 years.

Does anyone know of a good Asterisk Monitoring Solution that would fit the needs I just mentioned?

I certainly appreciate any suggestions.

Thanks,
Perry

By the way…
There are some good ones here:

I am just looking to see if anyone else has found an undiscovered diamond out there…

Thanks,
