How can I determine which SageMaker notebook instance made a particular API call if all the instances use the same IAM role?
"I have multiple Amazon SageMaker notebook instances. They all use the same AWS Identity and Access Management (IAM) role. The AWS CloudTrail event for each API action shows the same principalId (session name), no matter which notebook instance performed the action. How can I tell which notebook instance performed which API actions?"

How can I tell which notebook instance performed which API actions?Short descriptionWhen you have multiple SageMaker instances with the same IAM role, you can't determine which notebook instance performed a particular API action with the CloudTrail event.Example:{    "eventVersion": "1.05",    "userIdentity": {        "type": "AssumedRole",        "principalId": "AAAAAAAAAAAAAAAAAA:SageMaker",           "arn": "arn:aws:sts::111122223333:assumed-role/AmazonSageMaker-ExecutionRole/SageMaker",Resolution1.    Create an IAM execution role for the SageMaker notebook instance. Or, use an existing execution role. In the following steps, the Amazon Resource Name (ARN) for the execution role is arn:aws:iam::111122223333:role/service-role/AmazonSageMaker-ExecutionRole.2.    Attach an IAM policy that includes sts:AssumeRole to the execution role. The sts:AssumeRole action allows the execution role to assume itself using a different session name.Example:{    "Version": "2012-10-17",    "Statement": [        {            "Effect": "Allow",            "Action": "sts:AssumeRole",            "Resource": "arn:aws:iam::111122223333:role/service-role/AmazonSageMaker-ExecutionRole"        }    ]}3.    Create a Start notebook lifecycle configuration script similar to the following. This example script retrieves the notebook instance name and then uses the name as the session name.#Copyright Amazon.com, Inc. or its affiliates.

This restricts the user ec2-user from deleting or updating the config files.6.    To identify the notebook instance that performed an API action, check the CloudTrail event. Under the userIdentity object, the principalId and arn show the name of the notebook instance. For example, the following event detail shows that the SageMaker notebook instance test-2 made the API call.{    "eventVersion": "1.05",    "userIdentity": {        "type": "AssumedRole",        "principalId": "AAAAAAAAAAAAAAAAAAAA:test-2",        "arn": "arn:aws:sts::111122223333:assumed-role/AmazonSageMaker-ExecutionRole/test-2",        "accountId": "111122223333",        "accessKeyId": "AAAAAAAAAAAAAAAAAAAA",        "sessionContext": {            "sessionIssuer": {                "type": "Role",                "principalId": "AAAAAAAAAAAAAAAAAAAA",                "arn": "arn:aws:iam::111122223333:role/service-role/AmazonSageMaker-ExecutionRole",                "accountId": "111122223333",                "userName": "AmazonSageMaker-ExecutionRole"            },            "webIdFederationData": {},            "attributes": {                "mfaAuthenticated": "false",                "creationDate": "2020-09-12T00:45:04Z"            }        },        "invokedBy": "im.amazonaws.com"    },    "eventTime": "2020-09-12T00:49:04Z",    "eventSource": "sagemaker.amazonaws.com",    "eventName": "CreateEndpoint",    "awsRegion": "us-east-1",    "sourceIPAddress": "im.amazonaws.com",    "userAgent": "im.amazonaws.com",    "requestParameters": {        "endpointName": "sagemaker-mxnet-ep",        "endpointConfigName": "sagemaker-mxnet-epc",        "tags": []    },    "responseElements": {        "endpointArn": "arn:aws:sagemaker:us-east-1:111122223333:endpoint/sagemaker-mxnet-ep"    },    "requestID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",    "eventID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",    "eventType": "AwsApiCall",    "recipientAccountId": "111122223333"}Related informationSageMaker rolesFollow"
