Description

Creates or updates a subscription filter and associates it with the specified log group. With subscription filters, you can subscribe to a real-time stream of log events ingested through PutLogEvents and have them delivered to a specific destination. When log events are sent to the receiving service, they are Base64 encoded and compressed with the GZIP format. The following destinations are supported for subscription filters:
  • An Amazon Kinesis data stream belonging to the same account as the subscription filter, for same-account delivery.
  • A logical destination created with PutDestination that belongs to a different account, for cross-account delivery. We currently support Kinesis Data Streams and Firehose as logical destinations.
  • An Amazon Kinesis Data Firehose delivery stream that belongs to the same account as the subscription filter, for same-account delivery.
  • An Lambda function that belongs to the same account as the subscription filter, for same-account delivery.
Each log group can have up to two subscription filters associated with it. If you are updating an existing filter, you must specify the correct name in filterName. Using regular expressions to create subscription filters is supported. For these filters, there is a quotas of quota of two regular expression patterns within a single filter pattern. There is also a quota of five regular expression patterns per log group. For more information about using regular expressions in subscription filters, see Filter pattern syntax for metric filters, subscription filters, filter log events, and Live Tail. To perform a PutSubscriptionFilter operation for any destination except a Lambda function, you must also have the iam:PassRole permission.

Parameters

-ClientConfig <AmazonCloudWatchLogsConfig>
Amazon.PowerShell.Cmdlets.CWL.AmazonCloudWatchLogsClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-DestinationArn <String>
The ARN of the destination to deliver matching log events to. Currently, the supported destinations are:
  • An Amazon Kinesis stream belonging to the same account as the subscription filter, for same-account delivery.
  • A logical destination (specified using an ARN) belonging to a different account, for cross-account delivery.If you're setting up a cross-account subscription, the destination must have an IAM policy associated with it. The IAM policy must allow the sender to send logs to the destination. For more information, see PutDestinationPolicy.
  • A Kinesis Data Firehose delivery stream belonging to the same account as the subscription filter, for same-account delivery.
  • A Lambda function belonging to the same account as the subscription filter, for same-account delivery.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Distribution <Distribution>
The method used to distribute log data to the destination. By default, log data is grouped by log stream, but the grouping can be set to random for a more even distribution. This property is only applicable when the destination is an Amazon Kinesis data stream.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FilterName <String>
A name for the subscription filter. If you are updating an existing filter, you must specify the correct name in filterName. To find the name of the filter currently associated with a log group, use DescribeSubscriptionFilters.
Required?True
Position?2
Accept pipeline input?True (ByPropertyName)
-FilterPattern <String>
A filter pattern for subscribing to a filtered stream of log events.
Required?True
Position?3
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-LogGroupName <String>
The name of the log group.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the LogGroupName parameter. The -PassThru parameter is deprecated, use -Select '^LogGroupName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RoleArn <String>
The ARN of an IAM role that grants CloudWatch Logs permissions to deliver ingested log events to the destination stream. You don't need to provide the ARN when you are working with a logical destination for cross-account delivery.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The cmdlet doesn't have a return value by default. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatchLogs.Model.PutSubscriptionFilterResponse). 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
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False

-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
