Amazon Elastic Compute Cloud: New-EC2FlowLog Cmdlet

Synopsis

Calls the Amazon Elastic Compute Cloud CreateFlowLogs API operation.

Syntax

-ClientToken <String>

-LogDestination <String>
-LogDestinationType <LogDestinationType>
-ResourceId <String[]>
-ResourceType <FlowLogsResourceType>
-TrafficType <TrafficType>

Description

Creates one or more flow logs to capture information about IP traffic for a specific network interface, subnet, or VPC. Flow log data for a monitored network interface is recorded as flow log records, which are log events consisting of fields that describe the traffic flow. For more information, see Flow Log Records in the Amazon Virtual Private Cloud User Guide. When publishing to CloudWatch Logs, flow log records are published to a log group, and each network interface has a unique log stream in the log group. When publishing to Amazon S3, flow log records for all of the monitored network interfaces are published to a single log file object that is stored in the specified bucket. For more information, see VPC Flow Logs in the Amazon Virtual Private Cloud User Guide.

Note: For scripts written against earlier versions of this module this cmdlet can also be invoked with the alias, New-EC2FlowLogs.

Parameters

-ClientToken <String>

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see How to Ensure Idempotency.

Required?	False
Position?	Named
Accept pipeline input?	False

-DeliverLogsPermissionArn <String>

The ARN for the IAM role that's used to post flow logs to a log group.

Required?	False
Position?	Named
Accept pipeline input?	False

-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?	False

-LogDestination <String>

Specifies the destination to which the flow log data is to be published. Flow log data can be published to an CloudWatch Logs log group or an Amazon S3 bucket. The value specified for this parameter depends on the value specified for LogDestinationType.If LogDestinationType is not specified or cloud-watch-logs, specify the Amazon Resource Name (ARN) of the CloudWatch Logs log group.If LogDestinationType is s3, specify the ARN of the Amazon S3 bucket. You can also specify a subfolder in the bucket. To specify a subfolder in the bucket, use the following ARN format: bucket_ARN/subfolder_name/. For example, to specify a subfolder named my-logs in a bucket named my-bucket, use the following ARN: arn:aws:s3:::my-bucket/my-logs/.

Required?	False
Position?	Named
Accept pipeline input?	False

-LogDestinationType <LogDestinationType>

Specifies the type of destination to which the flow log data is to be published. Flow log data can be published to CloudWatch Logs or Amazon S3. To publish flow log data to CloudWatch Logs, specify cloud-watch-logs. To publish flow log data to Amazon S3, specify s3.Default: cloud-watch-logs

Required?	False
Position?	Named
Accept pipeline input?	False

-LogGroupName <String>

The name of the log group.

Required?	False
Position?	1
Accept pipeline input?	True (ByValue, )

-ResourceId <String[]>

One or more subnet, network interface, or VPC IDs.Constraints: Maximum of 1000 resources

Required?	False
Position?	Named
Accept pipeline input?	True (ByPropertyName)

-ResourceType <FlowLogsResourceType>

The type of resource on which to create the flow log.

Required?	False
Position?	Named
Accept pipeline input?	False

-TrafficType <TrafficType>

The type of traffic to log.

Required?	False
Position?	Named
Accept pipeline input?	False

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?	False

-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?	False

-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
Position?	Named
Accept pipeline input?	False

-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?	False

-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?	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.

Required?	False
Position?	Named
Accept pipeline input?	False

-SessionToken <String>

The session token if the access and secret keys are temporary session-based credentials.

Required?	False
Position?	Named
Accept pipeline input?	False

-Region <String>

The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.

Required?	False
Position?	Named
Accept pipeline input?	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. 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?	False

Inputs

System.String

You can pipe a String object to this cmdlet for the LogGroupName parameter.

Outputs

Amazon.EC2.Model.CreateFlowLogsResponse

This cmdlet returns a Amazon.EC2.Model.CreateFlowLogsResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Supported Version

AWS Tools for PowerShell: 2.x.y.z
