Establishes a threshold that, when reached, NetWitness generates a log message to help you resolve event flow issues. The Threshold is the size of the netflow event messages currently flowing from the event source to NetWitness .
Valid values are:
Caution: Only enable debugging (set this parameter to On or Verbose) if you have a problem with an event source and you need to investigate this problem. Enabling debugging will adversely affect the performance of the Log Collector .
Enables or disables debug logging for the event source.
Valid values are:
This parameter is designed to debug and monitor isolated event source collection issues. The debug logging is verbose, so limit the number of event sources to minimize performance impact.
