Debugging OpenStack services
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Since Pike release, TripleO now offers an easy way to enable per-service debug
without relying on knowledge of the puppet interfaces.
Each OpenStack service has now its own Debug parameter.
* Operators who want to enable Debug everywhere will set ``Debug`` to ``true``.
* Operators who want to disable Debug everywhere will set ``Debug`` to ``false``.
* Operators who want to disable Debug everywhere except for Glance will set ``Debug`` to
``false`` and ``GlanceDebug`` to ``true``.
* Operators who want to enable Debug everywhere except for Glance will set ``Debug`` to
``true`` and ``GlanceDebug`` to ``false``.
Glance was an example, but all OpenStack services are supported. You can find their Debug
in the TripleO Heat Templates composable services.
