groupings
The grouping applied to the metrics that are returned. For example, when results are grouped by queue, the metrics returned are grouped by queue. The values that are returned apply to the metrics for each queue. They are not aggregated for all queues.
If no grouping is specified, a summary of all metrics is returned.
