Synopsis

Calls the Amazon CloudWatch GetMetricWidgetImage API operation.

Syntax

Get-CWMetricWidgetImage
-MetricWidget <String>
-OutputFormat <String>
-Select <String>

Description

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.

Parameters

-MetricWidget <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.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-OutputFormat <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> 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 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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'MetricWidgetImage'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatch.Model.GetMetricWidgetImageResponse). Specifying the name of a property of type Amazon.CloudWatch.Model.GetMetricWidgetImageResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False

Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False

Aliases AWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information.

You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfileName, StoredCredentials
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False

-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage.
