Enabling Amazon CloudWatch Logs for a Neptune notebook

CloudWatch Logs for Neptune notebooks are disabled by default. Follow these steps to enable them, for debugging or other purposes:

Using the AWS Management Console to enable CloudWatch Logs for a Neptune notebook

1. Open the Amazon SageMaker console at https://console.aws.amazon.com/sagemaker/.

2. On the navigation pane on the left, choose Notebook, then Notebook Instances. Look for the name of the Neptune notebook for which you would like to enable logs.

3. Go to the details page by choosing the name of the notebook instance mentioned in the above step.

4. If the notebook instance is running, select the Stop button, at the top right of the notebook details page.

5. Under Permissions and encryption there is a field for IAM role ARN. Select the link in this field to go to the IAM role for this notebook.

6. Create the following policy:

   {
     "Version": "2012-10-17",
     "Statement": [
       {
         "Effect": "Allow",
         "Action": [
           "logs:CreateLogDelivery", 
           "logs:CreateLogGroup", 
           "logs:CreateLogStream", 
           "logs:DeleteLogDelivery", 
           "logs:Describe*", 
           "logs:GetLogDelivery", 
           "logs:GetLogEvents", 
           "logs:ListLogDeliveries", 
           "logs:PutLogEvents", 
           "logs:PutResourcePolicy", 
           "logs:UpdateLogDelivery"
         ],
         "Resource": "*"
       }
     ]
   }

7. Save this new policy, and attach it to the IAM role in step 4.

8. Select Start at the top right of the SageMaker notebook instance details page.

9. Once logs start flowing, you should see a View Logs link underneath the field labeled Lifecycle configuration near the bottom left of the Notebook instance settings section of the details page.

If your notebook fails to start there will be a message in the notebook details page on the SageMaker console stating that the notebook instance took more than 5 minutes to start. The CloudWatch Logs relevant to this issue can be found under the name: (your-notebook-name)/LifecycleConfigOnStart.

See Log Amazon SageMaker Events with Amazon CloudWatch for more details, if necessary.
