The Work Queue Instrumentation Purge batch process purges instrumentation data for work queues. This process uses Gosu class WorkQueueInstrumentationPurge to read the value of the InstrumentedWorkerInfoPurgeDaysOld parameter in config.xml. The process then uses this value to determine how long to retain work queue instrumentation data. The default value of InstrumentedWorkerInfoPurgeDaysOld is 45 (business) days.
