### Per-bucket Metrics

Metrics with a `/bucket` component in the path return results for each specified bucket in the deployment. These endpoints **require** providing a list of buckets as a `bucket` query parameter.  The endpoint then returns only metrics for the given buckets, with the bucket name in a `bucket` label.
