AWS Parallel Computing Service now supports scaling logs

AWS PCS Scaling Logs Now Available

AWS Parallel Computing Service (AWS PCS) now supports scaling logs, which record how AWS PCS scales the compute node groups in your cluster. Each log entry records one state transition for one compute node—for example, an instance launch, a node registration, a scale-down, or a launch failure with its reason. Using scaling logs, you can more easily troubleshoot scaling issues. For example, you can determine why a compute node group did not reach its target size, which launches failed for capacity reasons, and when a specific node started or stopped. Scaling log delivery is opt-in, and you can configure AWS PCS to emit scaling logs to Amazon CloudWatch Logs, Amazon S3, and Amazon Data Firehose.

What to do

• Enable scaling logs in your AWS PCS cluster settings.
• Configure log delivery to your preferred destination: Amazon CloudWatch Logs, Amazon S3, or Amazon Data Firehose.
• Review scaling logs to troubleshoot and optimize your cluster scaling.
