+Currently, the information is collected only by two observers: the :ref:`mongo_observer` and the :ref:`file_observer`. For the Mongo Observer, metrics are stored in the ``metrics`` collection of MongoDB and are identified by their name (e.g. "training.loss") and the experiment run id they belong to. For the :ref:`file_observer`, metrics are stored in the file ``metrics.json`` in the run id's directory and are organized by metric name (e.g. "training.loss").
