+OpenStack `Vitrage`_ is an RCA (Root Cause Analysis) service for organizing,
+analyzing and expanding OpenStack alarms & events. Vitrage implements Doctor
+Inspector, as it receives a notification that a host is down and calls Nova
+force-down API. In addition, it raises alarms on the instances running on this
+host.
+
+.. _Vitrage: https://wiki.openstack.org/wiki/Vitrage
+
+Vitrage is not deployed by OPNFV installers yet. It can be installed either on
+top of a devstack environment, or on top of a real OpenStack environment. See
+`Vitrage Installation`_

+
+Doctor SB API and a Doctor datasource were implemented in Vitrage in the Ocata
+release. The Doctor datasource is enabled by default.
+
+After Vitrage is installed and configured, there is a need to configure it to
+support the Doctor use case. This can be done in a few steps:
+
+1. Make sure that 'aodh' and 'doctor' are included in the list of datasource
+ types in /etc/vitrage/vitrage.conf:
+
+.. code-block:: bash
+
+ [datasources]
+ types = aodh,doctor,nova.host,nova.instance,nova.zone,static,cinder.volume,neutron.network,neutron.port,heat.stack
+
+2. Enable the Vitrage Nova notifier. Set the following line in
+ /etc/vitrage/vitrage.conf:
+
+.. code-block:: bash
+
+ [DEFAULT]
+ notifiers = nova
+
+3. Add a template that is responsible to call Nova force-down if Vitrage
+ receives a 'compute.host.down' alarm. Copy `template`_ and place it under
+ /etc/vitrage/templates
+
+.. _template: https://github.com/openstack/vitrage/blob/master/etc/vitrage/templates.sample/host_down_scenarios.yaml
+
+4. Restart the vitrage-graph and vitrage-notifier services
