While adding a profiler.cfg to an existing test case(Please refer 80-ND078-3 C to understand how to use profiler.cfg ), you might come across a point where the excell files generated by the test case are empty. This is because the default profiling sampling rate is set to 200000 in profiler.cfg
### Number of desired microseconds between profiling measurements (>=100000)
prof_sampling_period 200000
So the profiler will log output in excell files after every 200 msec. If the test case runs for a shorter duration than 200 msec, then the files will be blank.
As a solution you can do either of the two
1) Decrease prof_sampling_rate but make sure it's more than 100000
2) Increase the number of buffers in your test case, so that the test case duration increases.
