+========================
+Integration with Mistral
+========================
+
+launchpad blueprint:
+https://blueprints.launchpad.net/vitrage/+spec/integration-with-mistral
+
+Support executing Mistral workflows from Vitrage.
+
+Problem description
+===================
+
+Vitrage provides insights about the state of the cloud, but is not meant to be
+a policy engine. In order to take corrective actions, for example, we need to
+integrate an external engine like Mistral - the OpenStack workflow engine.
+
+Proposed change
+===============
+
+It will be possible to define in Vitrage templates that under certain
+conditions, a Mistral workflow should be executed. This gives the user the
+power to decide, for example, that different corrective actions should be taken
+based on the root cause of the problem (as identified by Vitrage).
+
+Note that this blueprint is based on the external-actions blueprint, that
+handles the more general case.
+
+Examples
+--------
+
+.. code-block:: yaml
+
+ - scenario:
+    condition: host_down_alarm_on_host
+    actions:
+     - action:
+        action_type: execute_mistral
+        properties:
+         workflow: wf1
+
+
+Alternatives
+------------
+Discussed in the external-actions blueprint.
