[ aws . cloudwatch ]



You can use the GetMetricWidgetImage API to retrieve a snapshot graph of one or more Amazon CloudWatch metrics as a bitmap image. You can then embed this image into your services and products, such as wiki pages, reports, and documents. You could also retrieve images regularly, such as every minute, and create your own custom live dashboard.

The graph you retrieve can include all CloudWatch metric graph features, including metric math and horizontal and vertical annotations.

There is a limit of 20 transactions per second for this API. Each GetMetricWidgetImage action has the following limits:

  • As many as 100 metrics in the graph.
  • Up to 100 KB uncompressed payload.

See 'aws help' for descriptions of global parameters.


--metric-widget <value>
[--output-format <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--metric-widget (string)

A JSON string that defines the bitmap graph to be retrieved. The string includes the metrics to include in the graph, statistics, annotations, title, axis limits, and so on. You can include only one MetricWidget parameter in each GetMetricWidgetImage call.

For more information about the syntax of MetricWidget see CloudWatch-Metric-Widget-Structure .

If any metric on the graph could not load all the requested data points, an orange triangle with an exclamation point appears next to the graph legend.

--output-format (string)

The format of the resulting image. Only PNG images are supported.

The default is png . If you specify png , the API returns an HTTP response with the content-type set to text/xml . The image data is in a MetricWidgetImage field. For example:

`` GetMetricWidgetImageResponse xmlns=URLstring``

`` GetMetricWidgetImageResult``

`` MetricWidgetImage``


`` /MetricWidgetImage``

`` /GetMetricWidgetImageResult``

`` ResponseMetadata``

`` RequestId6f0d4192-4d42-11e8-82c1-f539a07e0e3b/RequestId``

`` /ResponseMetadata``


The image/png setting is intended only for custom HTTP requests. For most use cases, and all actions using an AWS SDK, you should use png . If you specify image/png , the HTTP response has a content-type set to image/png , and the body of the response is a PNG image.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


MetricWidgetImage -> (blob)
