About types of recorded events
For each type of event, you can set the logging level to Standard or Detail. If you are using the default usage logging extension, UsrActivityLoggingExt, the logging level does not affect how the file records the following types of events:
*Report viewing
*Report printing
*Report deletion
If you set the logging level for report generation or factory events to Detail, the usage log includes report parameters. Setting the logging level to Detail for report generation events decreases performance.
