Step 2: Update the existing destination access policy - Amazon CloudWatch Logs
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Step 2: Update the existing destination access policy

After you have updated the subscription filters in all of the sender accounts, you can update the destination access policy in the recipient account.

In the following examples, the recipient account is 999999999999 and the destination is named testDestination.

The update enables all accounts that are part of the organization with ID o-1234567890 to send logs to the recipient account. Only the accounts that have subscription filters created will actually send logs to the recipient account.

To update the destination access policy in the recipient account to start using an organization ID for permissions

  1. In the recipient account, use a text editor to create a ~/AccessPolicy.json file with the following contents.

    { 
    "Version" : "2012-10-17", 
    "Statement" : [ 
        { 
            "Sid" : "", 
            "Effect" : "Allow",
            "Principal" : "*",
            "Action" : "logs:PutSubscriptionFilter", 
            "Resource" : "arn:aws:logs:region:999999999999:destination:testDestination",
            "Condition": {
               "StringEquals" : {
                   "aws:PrincipalOrgID" : ["o-1234567890"]
                }
            }
        } 
    ] 
}

  2. Enter the following command to attach the policy that you just created to the existing destination. To update a destination to use an access policy with an organization ID instead of an access policy that lists specific Amazon account IDs, include the force parameter.

    Warning

    If you are working with logs sent by an Amazon service listed in Enabling logging from Amazon services, then before doing this step, you must have first updated the subscription filters in all the sender accounts as explained in Step 1: Update the subscription filters.

    aws logs put-destination-policy 
    \ --destination-name "testDestination" 
    \ --access-policy file://~/AccessPolicy.json
    \ --force
