Since I didn't see any responses on the subject of CMDB and quite frankly it's not one of my favorite subjects anyway I've decided to write about something else...
I've recently been working with some WAN acceleration and/or optimization gear from Blue Coat, Cisco, and Riverbed. In working with this gear and with these vendors I have a need to compare the pre and post optimization traffic levels on a holistic level as well as per application, protocol, user group, destination, etc. This is completely doable with our current product set but required some manual manipulation of the data.
Having an easier way to do this analysis within the product would certainly help me and would be beneficial to the hardware vendors as it makes it easy to see the value that the appliances provides. But would it help you or is this a complete edge case?
