Worked on enhancing the log collection capabilities in the buildkite/elastic-ci-stack-for-aws repository, focusing on direct AWS log retrieval from EC2 instances and Lambda functions. Developed a more versatile CLI in Bash and Python, introducing options for stack name, instance ID, output format, AWS region, and time range. Improved error summarization and reporting, implemented stricter EC2 ID validation, and enabled recursive discovery of Lambda log groups within nested CloudFormation stacks. Added support for Windows log groups and strengthened error handling throughout the data collection process. Updated documentation in Markdown to reflect these changes, improving reliability and observability for AWS-based deployments.
June 2026 focused on delivering a robust Log Collector enhancement for the AWS EC2 and Lambda log pipelines in buildkite/elastic-ci-stack-for-aws. Delivered direct AWS log collection from EC2 instances and Lambda functions, with a expanded CLI (options include stack name, instance ID, output format, AWS region, and days) and a new error summarisation feature to provide actionable failure insights. Implemented robustness improvements across the data collection path (safer Lambda command piping, stricter EC2 ID validation) and enabled recursion into nested CloudFormation stacks to discover Lambda log groups. Added Windows log group handling and tightened error handling, with comprehensive README/docs updates. This set of changes improves reliability, reduces manual troubleshooting, and broadens coverage of log sources, driving faster incident response and better observability for AWS-based deployments.
