Configuring LUM License Servers to Log Events

The default configuration for IBM LUM license servers does not gather or retain enough information to be useful in reporting usage. By default, each LUM license server retains only 200 KB of log data. You must increase the log data limit to retain enough data to ensure that log data is not overwritten before the data is imported into FlexNet Manager for Engineering Applications.

By default, LUM license servers log only errors and do not log normal license usage data. In addition to logging errors, the LUM license servers need to log the following events:

  • Grant events
  • Release events
  • Timeout events

To minimize the size of the log files (and the event reports), it is recommended that you do not log Checkin events. LUM Checkin events are not the same as FlexNet licensing check-in events. LUM Checkin events are heartbeat events where the client must “check in” or make contact with the license server periodically.
