-- Publishes metric data points to Amazon CloudWatch. Amazon Cloudwatch
-- associates the data points with the specified metric. If the specified
-- metric does not exist, Amazon CloudWatch creates the metric. It can take
-- up to fifteen minutes for a new metric to appear in calls to the
-- ListMetrics action.
--
-- The size of a PutMetricData request is limited to 8 KB for HTTP GET
-- requests and 40 KB for HTTP POST requests.
--
-- Although the 'Value' parameter accepts numbers of type 'Double', Amazon
-- CloudWatch truncates values with very large exponents. Values with
-- base-10 exponents greater than 126 (1 x 10^126) are truncated. Likewise,
-- values with base-10 exponents less than -130 (1 x 10^-130) are also
-- truncated.
--
-- Data that is timestamped 24 hours or more in the past may take in excess
-- of 48 hours to become available from submission time using
-- 'GetMetricStatistics'.
