logging-best-practices

Structured logging formats log entries as JSON with rich context. The wide event pattern ensures a single log line contains all request details like request_id and duration_ms, enabling faster debugging and incident investigation.

To implement context enrichment, include essential fields like request_id, duration_ms, and status directly in your log entries. This approach provides dimensionality and allows you to filter logs to see the entire lifecycle of a problematic request.

Yes, this logging approach provides code patterns and examples in TypeScript, Ruby, and C#. It details best practices for JSON formatting, log levels, and robustness across these specific languages.

The best way to format logs for observability is using JSON formatting with the canonical log line approach. This ensures all requests generate a single, context-rich event for effective application monitoring.

Insufficient context in logs makes incident investigation difficult because it prevents correlation between events. Without structured fields like request_id, tracking the complete lifecycle of a problematic request is time-consuming and challenging.
