Description

Creates an export task so that you can efficiently export data from a log group to an Amazon S3 bucket. When you perform a CreateExportTask operation, you must use credentials that have permission to write to the S3 bucket that you specify as the destination. Exporting log data to S3 buckets that are encrypted by KMS is supported. Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled with a retention period is also supported. Exporting to S3 buckets that are encrypted with AES-256 is supported. This is an asynchronous call. If all the required information is provided, this operation initiates an export task and responds with the ID of the task. After the task has started, you can use DescribeExportTasks to get the status of the export task. Each account can only have one active (RUNNING or PENDING) export task at a time. To cancel an export task, use CancelExportTask. You can export logs from multiple log groups or multiple time ranges to the same S3 bucket. To separate log data for each export task, specify a prefix to be used as the Amazon S3 key prefix for all exported objects. We recommend that you don't regularly export to Amazon S3 as a way to continuously archive your logs. For that use case, we instaed recommend that you use subscriptions. For more information about subscriptions, see Real-time processing of log data with subscriptions. Time-based sorting on chunks of log data inside an exported file is not guaranteed. You can sort the exported log field data by using Linux utilities.

Parameters

-ClientConfig <AmazonCloudWatchLogsConfig>
Amazon.PowerShell.Cmdlets.CWL.AmazonCloudWatchLogsClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Destination <String>
The name of S3 bucket for the exported log data. The bucket must be in the same Amazon Web Services Region.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-DestinationPrefix <String>
The prefix used as the start of the key for every object exported. If you don't specify a value, the default is exportedlogs.The length of this parameter must comply with the S3 object key name length limits. The object key name is a sequence of Unicode characters with UTF-8 encoding, and can be up to 1,024 bytes.
Required?False
Position?Named
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)
-From <Int64>
The start time of the range for the request, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. Events with a timestamp earlier than this time are not exported.
Required?True
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)
-LogStreamNamePrefix <String>
Export only log streams that match the provided prefix. If you don't specify a value, no prefix filter is applied.
Required?False
Position?Named
Accept pipeline input?True (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)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'TaskId'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatchLogs.Model.CreateExportTaskResponse). Specifying the name of a property of type Amazon.CloudWatchLogs.Model.CreateExportTaskResponse 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)
-TaskName <String>
The name of the export task.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-To <Int64>
The end time of the range for the request, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. Events with a timestamp later than this time are not exported.You must specify a time that is not earlier than when this log group was created.
Required?True
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
