The Purge Profiler Data batch process purges profiler data at regularly specified intervals. This process uses the read-only ProfilerDataPurgeBatchProcess class to read the value of the ProfilerDataPurgeDaysOld parameter in config.xml. The process then uses the value of this parameter to determine how many days to retain profiler data before Purge Profiler Data batch process removes it.
