    :depth: 3

Summary
^^^^^^^
The EELF feature provides backwards compatibility with R0 logging functionality. It supports the use of EELF/Common Framework style logging at the same time as traditional logging.

.. seealso:: Additional information for EELF logging can be found at `EELF wiki`_.

.. _EELF wiki: https://github.com/att/EELF/wiki


Usage
^^^^^

To utilize the eelf logging capabilities, first stop policy engine and then enable the feature using the "*features*" command.

    .. code-block:: bash
       :caption: Enabling EELF Feature

        policy@hyperion-4:/opt/app/policy$ policy stop
        [drools-pdp-controllers]
         L []: Stopping Policy Management... Policy Management (pid=354) is stopping... Policy Management has stopped.
        policy@hyperion-4:/opt/app/policy$ features enable eelf
        name                      version         status
        ----                      -------         ------
        controlloop-utils         1.1.0-SNAPSHOT  disabled
        healthcheck               1.1.0-SNAPSHOT  disabled
        test-transaction          1.1.0-SNAPSHOT  disabled
        eelf                      1.1.0-SNAPSHOT  enabled
        state-management          1.1.0-SNAPSHOT  disabled
        active-standby-management 1.1.0-SNAPSHOT  disabled
        session-persistence       1.1.0-SNAPSHOT  disabled

The output of the enable command will indicate whether or not the feature was enabled successfully.

Policy engine can then be started as usual.
