Representing a statistic aggregate by operators

Parameters:
  • resource_id – id of resource to list statistics for.
  • meter_name – meter name of which we want the statistics.
  • period – Period in seconds over which to group samples.
  • granularity – frequency of marking metric point, in seconds.
  • dimensions – dimensions (dict). This param isn’t used in Gnocchi datasource.
  • aggregation – Should be chosen in accordance with policy aggregations.
  • group_by – list of columns to group the metrics to be returned. This param isn’t used in Gnocchi datasource.
Returns:

value of aggregated metric
