# Mistral Configuration

Vitrage can be configured to execute Mistral (the OpenStack Workflow service) workflows based on certain topology or alarm conditions.

## Enable Mistral Workflow Execution

To enable Mistral workflow execution, add mistral to the list of notifiers in /etc/vitrage/vitrage.conf file:

>     [DEFAULT]
>     notifiers = mistral

## Add execute_mistral action

To execute a Mistral workflow under a certain condition, add an ‘execute_mistral’ action to a template file:

>     scenarios:
>       - condition: host_down_alarm [on] host
>         actions:
>           - execute_mistral:
>              workflow: evacuate_host      # mandatory. The name of the workflow to be executed
>              input:
>                host_name: host1      # optional. A list of properties to be passed to the workflow
