<p>
The granularity, in seconds, to be used for the metric. For metrics with regular resolution, a period can be as
short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at
intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution
metrics are those metrics stored by a <code>PutMetricData</code> call that includes a
<code>StorageResolution</code> of 1 second.
