View log data for CodeDeploy EC2/On-Premises deployments

You can view the log data created by a CodeDeploy deployment by setting up the Amazon CloudWatch agent to view aggregated data in the CloudWatch console or by logging into an individual instance to review the log file.

Note

Logs are not supported for Amazon Lambda or Amazon ECS deployments. They can be created for EC2/On-Premises deployments only.

View log file data in the Amazon CloudWatch console

When the Amazon CloudWatch agent is installed on an instance, deployment data for all deployments to that instance becomes available for viewing in the CloudWatch console. For simplicity, we recommend using CloudWatch to centrally monitor log files instead of viewing them instance by instance. For more information, see Send CodeDeploy agent logs to CloudWatch.

View log files on an instance

To view deployment log data for an individual instance, you can sign in to the instance and browse for information about errors or other deployment events.
