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 = nova,mistral

Add execute_mistral action

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

- scenario:
    condition: host_down_alarm_on_host
    actions:
        action:
            action_type: execute_mistral
            properties:
                workflow: evacuate_host      # mandatory. The name of the workflow to be executed
                hostname: host1              # optional. A list of properties to be passed to the workflow
