[ 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.

--metric-widget <value>

[--cli-input-json | --cli-input-yaml]
[--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 eachGetMetricWidgetImage
call.For more information about the syntax of
MetricWidget
see GetMetricWidgetImage: Metric Widget Structure and Syntax .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 specifypng
, the API returns an HTTP response with the content-type set totext/xml
. The image data is in aMetricWidgetImage
field. For example:
<GetMetricWidgetImageResponse xmlns=<URLstring>>
<GetMetricWidgetImageResult>
<MetricWidgetImage>
iVBORw0KGgoAAAANSUhEUgAAAlgAAAGQEAYAAAAip...
</MetricWidgetImage>
</GetMetricWidgetImageResult>
<ResponseMetadata>
<RequestId>6f0d4192-4d42-11e8-82c1-f539a07e0e3b</RequestId>
</ResponseMetadata>
</GetMetricWidgetImageResponse>
The
image/png
setting is intended only for custom HTTP requests. For most use cases, and all actions using an AWS SDK, you should usepng
. If you specifyimage/png
, the HTTP response has a content-type set toimage/png
, and the body of the response is a PNG image.
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml
.
--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
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. 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)
The image of the graph, in the output format specified. The output is base64-encoded.
