If you are responsible for monitoring and managing a Cisco CallManager system, you sometimes have to extract, merge, and sort individual trace files to facilitate problem solving. This task may require manual logins to several different Cisco CallManager servers in a single cluster. The Cisco CallManager Trace Gathering Tool uses a web-browser-based interface to help automate this process.
