-- Creates or updates a metric filter and associates it with the specified
-- log group. Metric filters allow you to configure rules to extract metric
-- data from log events ingested through 'PutLogEvents' requests.
--
-- The maximum number of metric filters that can be associated with a log
-- group is 100.
