AWS Application Load Balancer now supports Health Check Logs

AWS Application Load Balancers (ALB) now supports Health Check Logs that allows you to send detailed target health check log data directly to your designated Amazon S3 bucket. This optional feature captures comprehensive target health check status, timestamp, target identification data, and failure reasons. Health Check Logs provide complete visibility into target health status with precise failure diagnostics, enabling faster troubleshooting without contacting AWS Support. You can analyze target’s health patterns over time, determine exactly why instances were marked unhealthy, and significantly reduce mean time to resolution for target health investigations. Logs are automatically delivered to your S3 bucket every 5 minutes with no additional charges beyond standard S3 storage costs. This feature is available in all AWS Commercial Regions, AWS GovCloud (US) Regions and AWS China Regions where Application Load Balancer is offered. You can enable Health Check Logs through the AWS Management Console, AWS CLI, or programmatically using the AWS SDK. Learn more about Health Check Logs for ALBs in the [AWS documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-monitoring.html).
