Under trace & log central -> Collect files: What setting should select to see changes made on the system by an administrator on CM Administration?
Getting down to what was actually done and piecing all the parts together is a more than convuluted process. My short answer to you would be No. The real answer is Yes but you are going to spend A LOT of time pulling data from various DB tables, Tomcat logs, and you also need to be quite proficient with leveraging AXL/SOAP to query data from the CUCM. Then you need to parse the data and put it all back together to get to exact info you need. Our practice lead has done this in the past for a customer but it is a tedious task (which is probably an understatement).
