Logs and Insights

CloudWatch Logs Insights helps you analyze, filter, and visualize logs from AWS services. Using structured JSON logs makes querying and aggregation much easier. Lambda Powertools and Middy are recommended for structured logging and middleware in Lambda functions. You can use features like log retention, masking sensitive data, and Live Tail for real-time log monitoring. Logs Insights supports SQL-like queries, visualizations, and sharing queries with your team for easier debugging and monitoring.
