Hello,

I would like to understand how the evaluation process works.

For example, I have this rule:

openstack alarm create --name memory_use_test \
  --type gnocchi_resources_threshold \
  --metric memory.usage \
  --threshold 102 \
  --comparison-operator gt \
  --aggregation-method mean \
  --granularity 60 \
  --evaluation-periods 3 \
  --resource-id dca36039-c603-422c-8366-f6ba4e9539c3 \
  --resource-type instance

Does this mean that when the alarm-evaluator service is running per a period, it will check the last 3 data points, each aggregated over 60 seconds?

Thank you. Regards.
