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
