AWS Lambda now publishes logs for Lambda Managed Instances capacity providers

AWS Lambda Managed Instances Logs

AWS Lambda now publishes logs for Lambda Managed Instances (LMI) capacity providers to Amazon CloudWatch Logs, providing visibility into scaling activity and instance lifecycle operations. This feature allows you to monitor, troubleshoot, and optimize managed EC2 instances, helping you quickly diagnose provisioning issues and understand scaling behavior.

Customers can use LMI to operate high-volume, predictable workloads with specialized compute configurations and achieve cost efficiency through EC2 pricing options like Savings Plans and Reserved Instances. Lambda automatically generates logs for compute resources managed by capacity providers and delivers them to CloudWatch Logs.

The capacity provider logs are available in all AWS Commercial Regions where LMI is available. The logs are enabled by default for all capacity providers. You can view your capacity provider logs by visiting the Lambda console's capacity provider page. You can use the Lambda API, Lambda console, AWS CLI, AWS SAM, or AWS CloudFormation to change capacity provider log configuration. Standard Amazon CloudWatch Logs charges apply.

What to do

• Monitor your capacity provider logs in the Lambda console.
• Use CloudWatch Logs filtering to identify failed operations and provisioning errors.
• Adjust log configuration using the Lambda API, Lambda console, AWS CLI, AWS SAM, or AWS CloudFormation.
