Synopsis

Calls the Application Auto Scaling DescribeScalingPolicies API operation.

Syntax

Get-AASScalingPolicy
-ServiceNamespace <ServiceNamespace>
-PolicyName <String[]>
-ResourceId <String>
-ScalableDimension <ScalableDimension>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonApplicationAutoScalingConfig>

Description

Describes the Application Auto Scaling scaling policies for the specified service namespace. You can filter the results using ResourceId, ScalableDimension, and PolicyNames. For more information, see Target tracking scaling policies and Step scaling policies in the Application Auto Scaling User Guide.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-ClientConfig <AmazonApplicationAutoScalingConfig>
Amazon.PowerShell.Cmdlets.AAS.AmazonApplicationAutoScalingClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxResult <Int32>
The maximum number of scalable targets. This value can be between 1 and 10. The default value is 10.If this parameter is used, the operation returns up to MaxResults results at a time, along with a NextToken value. To get the next set of results, include the NextToken value in a subsequent call. If this parameter is not used, the operation returns up to 10 results and a NextToken value, if applicable.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token for the next set of results.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
'NextToken' is only returned by the cmdlet when '-Select *' is specified. In order to manually control output pagination, set '-NextToken' to null for the first call then set the 'NextToken' using the same property output from the previous call for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the ServiceNamespace parameter. The -PassThru parameter is deprecated, use -Select '^ServiceNamespace' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PolicyName <String[]>
The names of the scaling policies to describe.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ApplicationAutoScaling.Model.DescribeScalingPoliciesResponse). Specifying the name of a property of type Amazon.ApplicationAutoScaling.Model.DescribeScalingPoliciesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
