--
-- 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. When Amazon
-- CloudWatch creates a metric, it can take up to fifteen minutes for the
-- metric to appear in calls to the < ListMetrics> action.
--
-- Each 'PutMetricData' request is limited to 8 KB in size for HTTP GET
-- requests and is limited to 40 KB in size for HTTP POST requests.
--
-- Although the 'Value' parameter accepts numbers of type 'Double', Amazon
-- CloudWatch rejects values that are either too small or too large. Values
-- must be in the range of 8.515920e-109 to 1.174271e+108 (Base 10) or
-- 2e-360 to 2e360 (Base 2). In addition, special values (e.g., NaN,
-- +Infinity, -Infinity) are not supported.
--
-- 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'.
