Open Stack

This situation can be caused by a lot of different things.

   - "gnocchi resource-type list" will show you the resource-types
   configured. Make sure you have configured the resource types that
   Ceilometer is pushing resources to
   - Make sure you have enabled metrics to be collected via polling.yml file
   - Make sure you have configured the "gnocchi_resources.yaml" file, and
   that the link between metrics, resources, and attributes to be pushed are
   correctly created
   - If want to generate metrics based on events, you then need to check :
   meters.yaml file, to see if everything is fine there
   - Make sure Ceilometer is pushing metrics and resource attributes to
   gnocchi. When the push is executed you will see the following DEBUG log
   messages:
      - Processing sample [%s] for resource ID [%s]
      - %d measures posted against %d metrics through %d resources
      - metric %s is not handled by Gnocchi (this one will appear if the
      metric is not configured to be pushed in the "gnocchi_resources.yaml")
