AmazonCloudWatchClient.PutMetricData Method (PutMetricDataRequest)

Publishes metric data to Amazon CloudWatch. CloudWatch associates the data 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.

You can publish metrics with associated entity data (so that related telemetry can be found and viewed together), or publish metric data by itself. To send entity data with your metrics, use the EntityMetricData parameter. To send metrics without entity data, use the MetricData parameter. The EntityMetricData structure includes MetricData structures for the metric data.

You can publish either individual values 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 MetricData 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 1 MB in size for HTTP POST requests. You can send a payload compressed by gzip. Each request is also limited to no more than 1000 different metrics (across both the MetricData and EntityMetricData properties).

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 30 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 in the Amazon CloudWatch User Guide.

You specify the time stamp to be associated with each data point. You can specify time stamps that are as much as two weeks before the current date, and as much as 2 hours after the current day and time.

Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for GetMetricData or GetMetricStatistics 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 GetMetricData or GetMetricStatistics.

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.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to PutMetricDataAsync.

Examples

This example shows how to publish a set of metric data points.

Publish metric data points example

var client = new AmazonCloudWatchClient();

var dimension = new Dimension
{
  Name = "Desktop Machine Metrics",
  Value = "Virtual Desktop Machine Usage"
};

var metric1 = new MetricDatum
{
  Dimensions = new List<Dimension>() { dimension },
  MetricName = "Desktop Machines Online",
  StatisticValues = new StatisticSet(),
  Timestamp = DateTime.Today,
  Unit = StandardUnit.Count,
  Value = 14
};

var metric2 = new MetricDatum
{
  Dimensions = new List<Dimension>() { dimension },
  MetricName = "Desktop Machines Offline",
  StatisticValues = new StatisticSet(),
  Timestamp = DateTime.Today,
  Unit = StandardUnit.Count,
  Value = 7
};

var metric3 = new MetricDatum
{
  Dimensions = new List<Dimension>() { dimension },
  MetricName = "Desktop Machines Online",
  StatisticValues = new StatisticSet(),
  Timestamp = DateTime.Today,
  Unit = StandardUnit.Count,
  Value = 12
};

var metric4 = new MetricDatum
{
  Dimensions = new List<Dimension>() { dimension },
  MetricName = "Desktop Machines Offline",
  StatisticValues = new StatisticSet(),
  Timestamp = DateTime.Today,
  Unit = StandardUnit.Count,
  Value = 9
};

var request = new PutMetricDataRequest
{
  MetricData = new List<MetricDatum>() { metric1, metric2, 
    metric3, metric4 },
  Namespace = "Example.com Custom Metrics"
};

client.PutMetricData(request);
