SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Centralizes and hardens application logging by converting ad-hoc console output into structured JSON logs with correlation IDs and PII-aware redaction so incidents are diagnosable, searchable, and compliant.

Core Features & Use Cases

  • Structured JSON output for consistent parsing, search, and schema enforcement across services.
  • Correlation and tracing: inject, propagate, and log requestId/traceId/spanId to correlate logs with traces.
  • PII redaction and policies to prevent sensitive data leakage and meet compliance requirements.
  • Aggregation & retention: guidance for ELK, Loki, and CloudWatch pipelines with environment-based retention tiers.
  • Performance and reliability: async logging, sampling, max-line-size guards, and verification checklists for production readiness.
  • Use case: migrate a Node/Go/Python service from console logs to pino/slog/structlog with propagated request IDs and ELK ingestion.

Quick Start

Run the logging audit and migration to enable JSON logs with correlation IDs, PII redaction, and ELK or Loki ingestion for your service.

FAQPage Schema
How do I convert console output to structured JSON logs in Node.js or Python?

Convert application console output into structured JSON logs by migrating to loggers like pino or structlog, ensuring consistent schema enforcement and reliable parsing across backend services. This enables searchable, centralized observability for distributed systems.

How does correlation ID propagation work for distributed system logging?

Correlation ID propagation works by injecting and logging requestId, traceId, and spanId through middleware that passes X-Request-Id and X-Trace-Id headers. This correlates logs with traces across distributed services for accurate incident diagnosis.

What is the best way to redact PII from application logs for compliance?

Redact PII from application logs by applying PII-aware redaction policies during structured JSON logging output. This prevents sensitive data leakage and satisfies compliance requirements in staging and production environments.

Can I use this logging migration approach with ELK, Loki, or CloudWatch?

This logging migration approach supports aggregation and retention pipelines like ELK, Loki, and CloudWatch. It provides environment-based retention tiers and ingestion guidance to ensure structured JSON logs are searchable and compliant.

Does structured logging support async writers and performance sampling?

Structured logging supports async writers, sampling, and max-line-size guards to maintain performance and reliability. These production readiness features prevent logging bottlenecks during high-throughput API platform operations.

Why do I need structured logging instead of plain console output?

Structured logging is needed because plain console output lacks consistent parsing, searchability, and schema enforcement. Converting to structured JSON logs with correlation IDs and PII redaction ensures incidents are diagnosable, searchable, and compliant.
