  - Type: GetMetricStatisticsResult

Errors :

• InternalService

  - Indicates that the request processing has failed due to some unknown error, exception, or failure.
  - HttpResponseCode: 500

ListMetrics

Description :

  - Returns a list of valid metrics stored for the AWS account owner. Returned metrics can be used with GetMetricStatistics to obtain statistical data for a given metric.
  - Note: Up to 500 results are returned for any one call. To retrieve further results, use returned NextToken values with subsequent ListMetrics operations.
  - Note: If you create a metric with the PutMetricData action, allow up to fifteen minutes for the metric to appear in calls to the ListMetrics action. Statistics about the metric, however, are available sooner using GetMetricStatistics.

PutMetricData

Request Parameters : Will Support :

Description

  - Publishes metric data points, which are associated specified metric. If the specified metric does not exist, it is created.
