概要
This skill helps developers transition from traditional text-based logging to high-signal wide events, also known as canonical log lines. By consolidating all technical metadata, business context, and error details into a single structured event per request, it eliminates the need for complex multi-search debugging. It provides comprehensive implementation patterns for Node.js and Express, including intelligent tail sampling logic that retains 100% of errors and high-value traffic while sampling the noise to optimize observability costs.
