Logging Module

A Logging Module captures application events, errors, and metrics in structured formats, forwarding to sinks like ELK or Splunk for analysis and alerting.

It supports levels (debug, info, error) and context enrichment.

Integrate Logging when:

• Debugging production issues post-deploy.
• Auditing user actions for compliance.
• Monitoring application health in real-time.
• Correlating events across microservices.

Note: Use Winston or Pino for Node.js.

Enrich with request IDs for tracing.

Rotate logs to manage disk usage.
