A huge argument in I.T. is "practical experience" vs "lot's of study of official course material" and the ups and downs of an engineer with tons of practical experience but no certs and an engineer with a few certs but not much experience.
I personally think both are extremely important and make for a well rounded engineer, but I can't count the number of engineers I have met who while very cluey have totally dismissed the need for certification and official vendor material which I feel is a mistake.
Am I getting to a point here? Yes I am. Today I wanted to talk about a tool I would never have discovered or realised how incredibly useful it is had I not been pursuing my CCIE Voice, that tool is the Real time monitoring tool, I assume ofcourse we have all heard about this tool if you use CUCM on a daily basis. But what you might not know is how incredibly useful it actually is.
One of the things I love about CCME is that I can debug things so easily, quick debug commands, lots of nice show commands make it easy for me to tell what is going on in my system, for example, if i want to know about an active call on a phone:
show ephone register

How do i pull up such relevant info on CUCM? Well Some info I am afraid you can't, but simply knowing that a call is indeed active can be done with the performance monitor.
First you need to go to the Application - Plugin page for CUCM, download and install the real time monitoring tool and login. Once you do click on "Performance" and select your server, you will be presented with so many things you can track! You can track things like attempted Extension Mobility logins, calls on a device, hits to hunt lists, just about everything!
I hope this helps someone out there
