// PutMetricDataRequest returns a request value for making API operation for
// Amazon CloudWatch.
//
// Publishes metric data points to Amazon CloudWatch. CloudWatch associates
// the data points with the specified metric. If the specified metric does not
// exist, CloudWatch creates the metric. When CloudWatch creates a metric, it
// can take up to fifteen minutes for the metric to appear in calls to ListMetrics
// (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_ListMetrics.html).
//
// You can publish either individual data points in the Value field, or arrays
// of values and the number of times each value occurred during the period by
// using the Values and Counts fields in the MetricDatum structure. Using the
// Values and Counts method enables you to publish up to 150 values per metric
// with one PutMetricData request, and supports retrieving percentile statistics
// on this data.
//
// Each PutMetricData request is limited to 40 KB in size for HTTP POST requests.
// You can send a payload compressed by gzip. Each request is also limited to
// no more than 20 different metrics.
//
// Although the Value parameter accepts numbers of type Double, CloudWatch rejects
// values that are either too small or too large. Values must be in the range
// of -2^360 to 2^360. In addition, special values (for example, NaN, +Infinity,
// -Infinity) are not supported.
//
// You can use up to 10 dimensions per metric to further clarify what data the
// metric collects. Each dimension consists of a Name and Value pair. For more
// information about specifying dimensions, see Publishing Metrics (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html)
// in the Amazon CloudWatch User Guide.
//
// Data points with time stamps from 24 hours ago or longer can take at least
// 48 hours to become available for GetMetricData (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html)
// or GetMetricStatistics (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricStatistics.html)
// from the time they are submitted. Data points with time stamps between 3
// and 24 hours ago can take as much as 2 hours to become available for for
// GetMetricData (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html)
// or GetMetricStatistics (https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricStatistics.html).
//
// CloudWatch needs raw data points to calculate percentile statistics. If you
// publish data using a statistic set instead, you can only retrieve percentile
// statistics for this data if one of the following conditions is true:
//
//    * The SampleCount value of the statistic set is 1 and Min, Max, and Sum
//    are all equal.
//
//    * The Min and Max are equal, and Sum is equal to Min multiplied by SampleCount.
//
//    // Example sending a request using PutMetricDataRequest.
//    req := client.PutMetricDataRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
//    }
