In the log file on your Snow License Manager application server, you can verify that the Cleanup Metering Service has executed the background processes according to schedule and see how long it took to complete.

note

  • The Cleanup Metering Service logs the background processes even when there is nothing to delete, for example, when no old data exists in the database or when the basic settings in Snow Management and Configuration Center are not enabled.

  • When you have enabled the basic settings in Snow Management and Configuration Center, the number of deleted rows and the processing time are logged.
