The main purpose of Vitrage is to provide insights about the state of the system on problems that are not directly monitored. An example of such a problem is a switch failure that causes a Nova host to become unreachable, while Nova is not aware of this problem.
The Nova notifier tries to solve this use case, by calling Nova force-down API to notify Nova that the host is down.
In order to support this use case, the user should perform the following:
[DEFAULT]
notifiers = nova
scenarios:
- scenario:
condition: host_down_alarm_on_host
actions:
action:
action_type : mark_down
action_target:
target: host
For more information about the mark-down action, see the Vitrage templates documentation: templates
