-- | The metric policy that is associated with the container. A metric policy
-- allows AWS Elemental MediaStore to send metrics to Amazon CloudWatch. In
-- the policy, you must indicate whether you want MediaStore to send
-- container-level metrics. You can also include rules to define groups of
-- objects that you want MediaStore to send object-level metrics for.
--
-- To view examples of how to construct a metric policy for your use case,
-- see
-- <https://docs.aws.amazon.com/mediastore/latest/ug/policies-metric-examples.html Example Metric Policies>.
