Aggregation Usage Data Maintenance

If usage data maintenance is enabled, the data cleanup service—which deletes the usage data—will be invoked in the following instances:

  • At reporting server startup.
  • When aggregation is finished.
  • When a change is made to a Usage Data Maintenance setting and saved.

After the data cleanup service is invoked, it checks whether usage data exists for deletion and then sequentially deletes:

  1. Hourly usage data
  2. Daily usage data
  3. Monthly usage data

For every type of usage data cleanup, one week’s worth data is deleted as one “chunk” and the data cleanup service continues deleting data until it deletes the data prior to the setting configured.
