Active Roles logging is disabled by default. It should only be enabled during troubleshooting scenarios as the logs may grow quite large in a very short period of time.
By default, Active Roles is installed on the C: drive and the log is located here:
C:\Program Files\One Identity\Active Roles\7.4\Service
TO ENABLE LOGGING
1. Open the Active Roles Configuration Center and navigate to the Logging tab.
2. Select Administration Service.
3. Select Modify
4. Select Turn on diagnostic log, then Verbose and click Ok.
To disable logging, select Modify and Turn off diagnostic log.
