Response Structure

  • (dict) --

    • deliveryDestinations (list) --

      An array of structures. Each structure contains information about one delivery destination in the account.

      • (dict) --

        This structure contains information about one delivery destination in your account. A delivery destination is an Amazon Web Services resource that represents an Amazon Web Services service that logs can be sent to. CloudWatch Logs, Amazon S3, Firehose, and X-Ray are supported as delivery destinations.

        To configure logs delivery between a supported Amazon Web Services service and a destination, you must do the following:

        • Create a delivery source, which is a logical object that represents the resource that is actually sending the logs. For more information, see PutDeliverySource.

        • Create a delivery destination, which is a logical object that represents the actual delivery destination.

        • If you are delivering logs cross-account, you must use PutDeliveryDestinationPolicy in the destination account to assign an IAM policy to the destination. This policy allows delivery to that destination.

        • Create a delivery by pairing exactly one delivery source and one delivery destination. For more information, see CreateDelivery.

        You can configure a single delivery source to send logs to multiple destinations by creating multiple deliveries. You can also create multiple deliveries to configure multiple delivery sources to send logs to the same delivery destination.

          The name of this delivery destination.

        • deliveryDestinationConfiguration (dict) --

          A structure that contains the ARN of the Amazon Web Services resource that will receive the logs.

          • destinationResourceArn (string) --

            The ARN of the Amazon Web Services destination that this delivery destination represents. That Amazon Web Services destination can be a log group in CloudWatch Logs, an Amazon S3 bucket, or a delivery stream in Firehose.

        • roleArn (string) --

          The ARN of the IAM role that CloudWatch Logs assumes to deliver to this delivery destination. This field is present only for X-Ray trace delivery destinations that were created with a role.

PutDeliveryDestination (updated) Link ¶
Changes (request, response)
Request
{'roleArn': 'string'}
Response
{'deliveryDestination': {'roleArn': 'string'}}

Creates or updates a logical delivery destination. A delivery destination is an Amazon Web Services resource that represents an Amazon Web Services service that logs can be sent to. CloudWatch Logs, Amazon S3, and Firehose are supported as logs delivery destinations and X-Ray as the trace delivery destination.

To configure logs delivery between a supported Amazon Web Services service and a destination, you must do the following:

  • Create a delivery source, which is a logical object that represents the resource that is actually sending the logs. For more information, see PutDeliverySource.

  • Use PutDeliveryDestination to create a delivery destination in the same account of the actual delivery destination. The delivery destination that you create is a logical object that represents the actual delivery destination.

  • If you are delivering logs cross-account, you must use PutDeliveryDestinationPolicy in the destination account to assign an IAM policy to the destination. This policy allows delivery to that destination.

  • Use CreateDelivery to create a delivery by pairing exactly one delivery source and one delivery destination. For more information, see CreateDelivery.

You can configure a single delivery source to send logs to multiple destinations by creating multiple deliveries. You can also create multiple deliveries to configure multiple delivery sources to send logs to the same delivery destination.

Only some Amazon Web Services services support being configured as a delivery source. These services are listed as Supported [V2 Permissions] in the table at Enabling logging from Amazon Web Services services.

If you use this operation to update an existing delivery destination, all the current delivery destination parameters are overwritten with the new parameter values that you specify.
