Enable Debug Mode for Capturing the Detailed Level Logs (Custom DB)

Customer Managed Applies to customer-managed instances of Alation

Applies from version 2020.4

Enabling the Debug mode captures the details available in the Debug mode in the Taskserver logs. You can locate the taskserver.log file which has the Debug mode details at /opt/alation/site/logs/.


Debug mode generates more Taskserver logs with increased log size that might require additional disk space. Alation recommends using the DEBUG mode only when you want to perform detail level debugging.

Enable the debug mode in alation_conf:

  1. Enter the Alation shell:

    sudo /etc/init.d/alation shell
  2. Using alation_conf, set the alation.logging.adbc_log_level flag to DEBUG. By default, the flag is set to INFO.

    alation_conf alation.logging.adbc_log_level -s DEBUG
    alation.logging.adbc_log_level = DEBUG


    TRACE mode is not supported.

  3. Restart the Java processes:

    alation_supervisor restart java:*

Users can find the debug details of the following processes in the the Taskserver logs:

  • MDE

  • QLI
