API Reference (API Version 2010-08-01)

PutMetricData

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 ListMetrics.

Each PutMetricData request 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.

You can use up to 10 dimensions per metric to further clarify what data the metric collects. For more information on specifying dimensions, see Publishing Metrics 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 GetMetricStatistics from the time they are submitted.
