During multiple test runs, the Reset Trace button should be clicked in order to flush the prior trace data and prepare the trace files for a new run.

 

Note that the active setting for Log File Folder controls where the trace files reside on the server.  If you would like to save a particular set of trace files, you need to save a copy of the FlyHL.log and FlyServ.log files.  To view them in the future, copy to the active log files folder.
