The .log file is missing from JazzTeamServer .metadata directory

In most client-side Eclipse applications, the workspace/.metadata/.log file is created automatically by the Eclipse framework when necessary. If the Eclipse framework doesn't need to log anything, then the file is never created.
I am not very familiar with how logging works on a Jazz server. I don't know if your server didn't log anything through the Eclipse framework, or if all log messages are sent somewhere else.
