Hi All,

I want to make this use case

[cid:image001.jpg at 01D31812.5F011220]

So I have used this Nagios config "/etc/vitrage/nagios_conf.yaml"

nagios:
- nagios_host: myhost
   type: nova.host
   name: hjtg2132-HP-ProDesk-600-G2-MT


And I have used this template "host_high_cpu_load_to_instance_cpu_suboptimal.yaml"

metadata:
    name: host_high_cpu_load_to_instance_cpu_suboptimal
    description: when there is high cpu on the host, show implications on the instances
definitions:
    entities:

        - entity:
            category: ALARM
            type: host_high_cpu_load
            template_id: host_alarm # some string
        - entity:
            category: ALARM
            type: instance_cpu_performance_problem
            template_id: instance_alarm
        - entity:
            category: RESOURCE
            type: nova.host
            template_id: host
        - entity:
           category: RESOURCE
            type: nova.instance
            template_id: instance
    relationships:
        - relationship:
            source: host_alarm  # source and target from entities section
            target: host
            relationship_type: on
            template_id : alarm_on_host
        - relationship:
            source: instance_alarm
            target: instance
            relationship_type: on
            template_id : alarm_on_instance
        - relationship:
            source: host
            target: instance
            relationship_type: contains
            template_id : host_contains_instance

scenarios:

- scenario:
    condition: alarm_on_host
    actions:
     - action:
        action_type: set_state
        action_target:
         target: host
        properties:
         state: ERROR
- scenario:
    condition: alarm_on_host and host_contains_instance
    actions:
     - action:
        action_type: raise_alarm
        action_target:
         target: instance
        properties:
         alarm_name: Instance cpu Consumption is suboptimal
         severity: critical
     - action:
        action_type: set_state
        action_target:
         target: instance
        properties:
         state: ERROR
- scenario:
    condition: alarm_on_host and host_contains_instance and alarm_on_instance
    actions:
     - action:
        action_type: add_causal_relationship
        action_target:
         source: host_alarm
         target: instance_alarm


I can see the alarm from Nagios on the host.
But I don't see the state changes and I don't see the alarms rises on instances so I don't see the root cause schema.
Please find attached pictures showing that.

I would appreciate if you can help me to solve this.

Thanking you + best regards,
Bader
