Synopsis

Calls the AWS Auto Scaling DescribeScalingActivities API operation.

Syntax

Get-ASScalingActivity
-AutoScalingGroupName <String>
-ActivityId <String[]>
-IncludeDeletedGroup <Boolean>
-MaxRecord <Int32>
-NextToken <String>
-Select <String>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonAutoScalingConfig>

Description

Gets information about the scaling activities in the account and Region. When scaling events occur, you see a record of the scaling activity in the scaling activities. For more information, see Verify a scaling activity for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide. If the scaling event succeeds, the value of the StatusCode element in the response is Successful. If an attempt to launch instances failed, the StatusCode value is Failed or Cancelled and the StatusMessage element in the response indicates the cause of the failure. For help interpreting the StatusMessage, see Troubleshooting Amazon EC2 Auto Scaling in the Amazon EC2 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

-ActivityId <String[]>
The activity IDs of the desired scaling activities. If you omit this property, all activities for the past six weeks are described. If unknown activities are requested, they are ignored with no error. If you specify an Auto Scaling group, the results are limited to that group.Array Members: Maximum number of 50 IDs. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

-AutoScalingGroupName <String>
The name of the Auto Scaling group.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-ClientConfig <AmazonAutoScalingConfig>
Amazon.PowerShell.Cmdlets.AS.AmazonAutoScalingClientCmdlet.ClientConfig
Required?False

Accept pipeline input?True (ByPropertyName)
-IncludeDeletedGroup <Boolean>
Indicates whether to include scaling activity from deleted Auto Scaling groups.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesIncludeDeletedGroups
-MaxRecord <Int32>
The maximum number of items to return with this call. The default value is 100 and the maximum value is 100.
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, MaxRecords
-NextToken <String>
The token for the next set of items to return. (You received this token from a previous call.)
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)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Activities'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.AutoScaling.Model.DescribeScalingActivitiesResponse). Specifying the name of a property of type Amazon.AutoScaling.Model.DescribeScalingActivitiesResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
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)
AliasesAK
-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 (ByValue, ByPropertyName)
-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. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-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
Position?Named
Accept pipeline input?True (ByValue, 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.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
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. 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

Accept pipeline input?True (ByPropertyName)
