Problem / User Need

As a developer and operator, I need a unified logging system that:

  • Provides consistent log levels across all 6 containers (Frontend, Backend, OCR, PostgreSQL, Redis, Traefik)
  • Is controlled by a single LOG_LEVEL environment variable set in CI/CD
  • Aggregates all logs to a searchable, centralized system
  • Supports request correlation across services
  • Replaces the current manual debug process documented in docs/UX-DEBUGGING.md

Currently, enabling debug logging requires manually modifying vite.config.ts Terser/ESBuild options and rebuilding. There is no unified log level control, no correlation IDs, and no centralized log aggregation.

Proposed Solution

Implement a unified logging system with:

  1. Single Control Variable: LOG_LEVEL (DEBUG, INFO, WARN, ERROR) set in CI/CD
  2. Config Generator: scripts/ci/generate-log-config.sh maps single variable to per-container settings
  3. Application Logging: Custom logger (Frontend), Pino (Backend/OCR) with correlation IDs
  4. Database Logging: PostgreSQL and Redis configured via mapped environment variables
  5. Log Aggregation: Self-hosted Promtail + Loki + Grafana stack
  6. Docker Rotation: Aggressive rotation (10m x 3 files) - Docker as buffer, Loki as retention

Unified LOG_LEVEL Mapping

LOG_LEVEL Frontend Backend OCR PostgreSQL Redis Traefik
DEBUG debug debug debug all queries, 0ms threshold debug DEBUG
INFO info info info DDL only, 500ms slow query verbose INFO
WARN warn warn warn errors + 1000ms slow query notice WARN
ERROR error error error errors only warning ERROR

Plan: Unified Debug Logging System

Phase: Planning | Agent: Orchestrator | Status: IN_PROGRESS


Codebase Analysis Summary

Current State Findings:

Component Status Details
Backend Logger Winston (not Pino) 79 files import logger.ts, hardcoded level: 'info'
Request IDs Missing No correlation ID propagation anywhere
Traefik Partial JSON access logs enabled, no X-Request-Id
Frontend Console only 242 console.log calls, no centralized logger
Docker Logging Default No log rotation, no aggregation
Container Count 6 (not 5) Traefik, Frontend, Backend, OCR, PostgreSQL, Redis

Key Gap: Issue assumes Pino, but backend uses Winston (79 files).


Architectural Decision: Winston vs Pino

Decision-Critic Verdict: REVISE - Migrate to Pino

Factor Winston (Current) Pino (Recommended)
Performance ~5K logs/sec ~30K logs/sec (6x faster)
Fastify Integration Manual Native (@fastify/pino)
Correlation IDs Must build manually Built-in request logging
Migration Cost Zero Low (wrapper pattern)
Maintenance Higher (custom integration) Lower (ecosystem maintained)

Decision: Migrate to Pino using a wrapper pattern in logger.ts that maintains API compatibility. This allows:

  • Zero changes to 79 importing files
  • Built-in correlation IDs via @fastify/pino
  • Long-term maintainability

Sub-Issue Breakdown

This feature is too large for a single AI context. Breaking into 7 smaller issues:

Sub-Issue Title Scope Dependencies
#80-A Config Generator Script scripts/ci/generate-log-config.sh None
#80-B Backend: Pino Migration + Correlation IDs backend/src/core/logging/, plugins #80-A
#80-C Traefik: X-Request-Id Middleware config/traefik/ None
#80-D Frontend Logger Module frontend/src/utils/logger.ts #80-A
#80-E Docker Logging + Rotation docker-compose.yml logging blocks None
#80-F Promtail + Loki + Grafana Stack New containers, configs #80-E
#80-G CI/CD Integration + Documentation Workflows, docs All above

Implementation Plan

Milestone 1: Foundation (Sub-issues #80-A, #80-C, #80-E)

Parallel execution possible

#80-A: Config Generator Script

  • Create scripts/ci/generate-log-config.sh
  • Accept LOG_LEVEL (DEBUG, INFO, WARN, ERROR)
  • Generate .env.logging with per-container mappings
  • Acceptance: Script runs, validates input, outputs correct mappings

#80-C: Traefik X-Request-Id

  • Add x-request-id middleware to config/traefik/dynamic/middleware.yml
  • Configure header generation if missing, forwarding if present
  • Add to api-chain, platform-chain middleware stacks
  • Acceptance: Requests have X-Request-Id header in access logs

#80-E: Docker Logging Configuration

  • Add logging: block to all 6 services in docker-compose.yml
  • Configure json-file driver with 10m max-size, 3 max-file
  • Acceptance: Log rotation working, no unbounded growth

Milestone 2: Backend Logging (Sub-issue #80-B)

Depends on #80-A

#80-B: Pino Migration + Correlation IDs

Files to modify:

  1. backend/src/core/logging/logger.ts - Replace Winston with Pino wrapper
  2. backend/src/core/plugins/logging.plugin.ts - Use @fastify/pino
  3. backend/package.json - Add pino, @fastify/pino; remove winston

Implementation:

// logger.ts - Pino wrapper maintaining Winston API
import pino from 'pino';

const pinoLogger = pino({
  level: process.env.LOG_LEVEL?.toLowerCase() || 'info',
  formatters: { level: (label) => ({ level: label }) },
});

// Wrapper maintains logger.info(msg, meta) API
export const logger = {
  info: (msg: string, meta?: object) => pinoLogger.info(meta || {}, msg),
  warn: (msg: string, meta?: object) => pinoLogger.warn(meta || {}, msg),
  error: (msg: string, meta?: object) => pinoLogger.error(meta || {}, msg),
  debug: (msg: string, meta?: object) => pinoLogger.debug(meta || {}, msg),
  child: (bindings: object) => {
    const childPino = pinoLogger.child(bindings);
    return {
      info: (msg: string, meta?: object) => childPino.info(meta || {}, msg),
      // ... same pattern
    };
  },
};

Correlation ID middleware:

  • Use @fastify/pino's built-in request logging
  • Extract X-Request-Id from headers or generate UUID
  • Store in AsyncLocalStorage for child logger access

Acceptance:

  • LOG_LEVEL env var controls verbosity
  • All logs include requestId
  • 79 importing files unchanged

Milestone 3: Frontend Logging (Sub-issue #80-D)

Depends on #80-A

#80-D: Frontend Logger Module

Create frontend/src/utils/logger.ts:

const LOG_LEVEL = import.meta.env.VITE_LOG_LEVEL || 'info';
const LEVELS = { debug: 0, info: 1, warn: 2, error: 3 };

const shouldLog = (level: keyof typeof LEVELS) => 
  LEVELS[level] >= LEVELS[LOG_LEVEL as keyof typeof LEVELS];

export const logger = {
  debug: (msg: string, meta?: object) => 
    shouldLog('debug') && console.debug(`[DEBUG] ${msg}`, meta),
  info: (msg: string, meta?: object) => 
    shouldLog('info') && console.log(`[INFO] ${msg}`, meta),
  warn: (msg: string, meta?: object) => 
    shouldLog('warn') && console.warn(`[WARN] ${msg}`, meta),
  error: (msg: string, meta?: object) => 
    shouldLog('error') && console.error(`[ERROR] ${msg}`, meta),
};

Modify frontend/vite.config.ts:

  • Add VITE_LOG_LEVEL to define() if not present
  • Keep drop_console: false (intentional per current config)

Update API client to include requestId in logs for correlation.

Acceptance:

  • VITE_LOG_LEVEL controls frontend verbosity
  • API calls logged with requestId
  • Sensitive data sanitized

Milestone 4: Log Aggregation Stack (Sub-issue #80-F)

Depends on #80-E

#80-F: Promtail + Loki + Grafana

Add to docker-compose.yml:

  • mvp-promtail: Scrapes Docker logs, forwards to Loki
  • mvp-loki: Log storage with 30-day retention
  • mvp-grafana: Visualization with Loki datasource

Create configs:

  • config/promtail/config.yml - Docker log scraping
  • config/loki/config.yml - Storage, retention, index

Container count: 6 → 9

Acceptance:

  • All 6 service logs visible in Grafana
  • Query by requestId, container, level
  • 30-day retention working

Milestone 5: CI/CD + Documentation (Sub-issue #80-G)

Depends on all above

#80-G: CI/CD Integration

Modify workflows:

  • .gitea/workflows/staging.yaml: Run generate-log-config.sh DEBUG
  • .gitea/workflows/production.yaml: Run generate-log-config.sh INFO
  • Source .env.logging before docker-compose up

Update documentation:

  • Replace docs/UX-DEBUGGING.md with new logging system docs
  • Update README.md container count (6 → 9)
  • Document Grafana access and LogQL queries

Acceptance:

  • Staging deploys with DEBUG
  • Production deploys with INFO
  • Documentation accurate and complete

Breaking into 7 smaller issues: | Sub-Issue | Title | Scope | Dependencies | |-----------|-------|-------|--------------| | #80-A | Config Generator Script | `scripts/ci/generate-log-config.sh` | None | | #80-B | Backend: Pino Migration + Correlation IDs | `backend/src/core/logging/`, plugins | #80-A | | #80-C | Traefik: X-Request-Id Middleware | `config/traefik/` | None | | #80-D | Frontend Logger Module | `frontend/src/utils/logger.ts` | #80-A | | #80-E | Docker Logging + Rotation | `docker-compose.yml` logging blocks | None | | #80-F | Promtail + Loki + Grafana Stack | New containers, configs | #80-E | | #80-G | CI/CD Integration + Documentation | Workflows, docs | All above | --- ### Implementation Plan #### Milestone 1: Foundation (Sub-issues #80-A, #80-C, #80-E) **Parallel execution possible** **#80-A: Config Generator Script** - Create `scripts/ci/generate-log-config.sh` - Accept LOG_LEVEL (DEBUG, INFO, WARN, ERROR) - Generate `.env.logging` with per-container mappings - Acceptance: Script runs, validates input, outputs correct mappings **#80-C: Traefik X-Request-Id** - Add `x-request-id` middleware to `config/traefik/dynamic/middleware.yml` - Configure header generation if missing, forwarding if present - Add to api-chain, platform-chain middleware stacks - Acceptance: Requests have X-Request-Id header in access logs **#80-E: Docker Logging Configuration** - Add `logging:` block to all 6 services in docker-compose.yml - Configure json-file driver with 10m max-size, 3 max-file - Acceptance: Log rotation working, no unbounded growth --- #### Milestone 2: Backend Logging (Sub-issue #80-B) **Depends on #80-A** **#80-B: Pino Migration + Correlation IDs** Files to modify: 1. `backend/src/core/logging/logger.ts` - Replace Winston with Pino wrapper 2. `backend/src/core/plugins/logging.plugin.ts` - Use @fastify/pino 3. `backend/package.json` - Add pino, @fastify/pino; remove winston Implementation: ```typescript // logger.ts - Pino wrapper maintaining Winston API import pino from 'pino'; const pinoLogger = pino({ level: process.env.LOG_LEVEL?.toLowerCase() || 'info', formatters: { level: (label) => ({ level: label }) }, }); // Wrapper maintains logger.info(msg, meta) API export const logger = { info: (msg: string, meta?: object) => pinoLogger.info(meta || {}, msg), warn: (msg: string, meta?: object) => pinoLogger.warn(meta || {}, msg), error: (msg: string, meta?: object) => pinoLogger.error(meta || {}, msg), debug: (msg: string, meta?: object) => pinoLogger.debug(meta || {}, msg), child: (bindings: object) => { const childPino = pinoLogger.child(bindings); return { info: (msg: string, meta?: object) => childPino.info(meta || {}, msg), // ... same pattern }; }, }; ``` Correlation ID middleware: - Use @fastify/pino's built-in request logging - Extract X-Request-Id from headers or generate UUID - Store in AsyncLocalStorage for child logger access Acceptance: - LOG_LEVEL env var controls verbosity - All logs include requestId - 79 importing files unchanged --- #### Milestone 3: Frontend Logging (Sub-issue #80-D) **Depends on #80-A** **#80-D: Frontend Logger Module** Create `frontend/src/utils/logger.ts`: ```typescript const LOG_LEVEL = import.meta.env.VITE_LOG_LEVEL || 'info'; const LEVELS = { debug: 0, info: 1, warn: 2, error: 3 }; const shouldLog = (level: keyof typeof LEVELS) => LEVELS[level] >= LEVELS[LOG_LEVEL as keyof typeof LEVELS]; export const logger = { debug: (msg: string, meta?: object) => shouldLog('debug') && console.debug(`[DEBUG] ${msg}`, meta), info: (msg: string, meta?: object) => shouldLog('info') && console.log(`[INFO] ${msg}`, meta), warn: (msg: string, meta?: object) => shouldLog('warn') && console.warn(`[WARN] ${msg}`, meta), error: (msg: string, meta?: object) => shouldLog('error') && console.error(`[ERROR] ${msg}`, meta), }; ``` Modify `frontend/vite.config.ts`: - Add VITE_LOG_LEVEL to define() if not present - Keep drop_console: false (intentional per current config) Update API client to include requestId in logs for correlation. Acceptance: - VITE_LOG_LEVEL controls frontend verbosity - API calls logged with requestId - Sensitive data sanitized --- #### Milestone 4: Log Aggregation Stack (Sub-issue #80-F) **Depends on #80-E** **#80-F: Promtail + Loki + Grafana** Add to docker-compose.yml: - `mvp-promtail`: Scrapes Docker logs, forwards to Loki - `mvp-loki`: Log storage with 30-day retention - `mvp-grafana`: Visualization with Loki datasource Create configs: - `config/promtail/config.yml` - Docker log scraping - `config/loki/config.yml` - Storage, retention, index Container count: 6 → 9 Acceptance: - All 6 service logs visible in Grafana - Query by requestId, container, level - 30-day retention working --- #### Milestone 5: CI/CD + Documentation (Sub-issue #80-G) **Depends on all above** **#80-G: CI/CD Integration** Modify workflows: - `.gitea/workflows/staging.yaml`: Run `generate-log-config.sh DEBUG` - `.gitea/workflows/production.yaml`: Run `generate-log-config.sh INFO` - Source `.env.logging` before docker-compose up Update documentation: - Replace `docs/UX-DEBUGGING.md` with new logging system docs - Update README.md container count (6 → 9) - Document Grafana access and LogQL queries Acceptance: - Staging deploys with DEBUG - Production deploys with INFO - Documentation accurate and complete --- ### Quality Gates | Gate | Criteria | |------|----------| | Plan-Completeness | All sub-issues defined, dependencies clear | | Plan-Code | RULE 0/1/2 compliance assessed | | Plan-Docs | Documentation updates specified | | Post-Implementation | Per-milestone QR review | | Final Review | Quality Agent validates all rules | --- ### Test Plan **Unit Tests:** - Config generator produces correct mappings for each LOG_LEVEL - Logger wrapper maintains API compatibility - Frontend logger respects VITE_LOG_LEVEL **Integration Tests:** - Request with X-Request-Id flows through Traefik → Backend → logs - Logs appear in Loki with correct labels - Log rotation creates new files at 10MB **Manual Tests:** - Set LOG_LEVEL=DEBUG, verify all containers log at debug - Set LOG_LEVEL=ERROR, verify only errors logged - Query Grafana by requestId across containers --- *Verdict*: AWAITING_REVIEW | *Next*: QR plan-completeness review

TW Review: Plan Revisions

Phase: Plan-Review | Agent: Technical Writer | Status: COMPLETE

Following QR plan-completeness review, the following additions are incorporated:


Revision A: Environment Defaults

Environment LOG_LEVEL Purpose
Development (.env.local) DEBUG Full debugging locally
Test (.env.test) ERROR Suppress noise in tests
Staging DEBUG Full debugging in staging
Production INFO Standard production logging

Revision B: Loki Failure Behavior

Failure Resilience:

  • Promtail retries with exponential backoff (10s to 1m)
  • Docker logs buffer locally with 10-minute rotation (3 files = ~30 min retention)
  • If Loki recovery fails, logs older than 30 min are lost
  • Mitigation: Loki container must be kept running; no graceful degradation
  • Acceptable Risk: Single-tenant app; operator can restart Loki during outage

Revision C: Implementation Risks

Risk Severity Impact Mitigation
Winston->Pino migration breaks API HIGH 79 files depend on logger.ts Wrapper maintains logger.info(msg, meta) API; regression testing
Traefik misses X-Request-Id on startup MEDIUM Early requests lack correlation Generate UUID if header missing (acceptable)
Loki unavailability MEDIUM Logs lost after 30-min buffer Keep Loki running; future: persistent queue
Container count increase (6->9) LOW Resource footprint <500MB combined for logging stack
Configuration complexity MEDIUM More env vars Single LOG_LEVEL + generate-log-config.sh automates

Revision D: Container Count Clarification

Current: 6 application containers (Traefik, Frontend, Backend, OCR, PostgreSQL, Redis)
After: 9 total (6 application + 3 logging: Promtail, Loki, Grafana)

Note: Logging containers optional for local development; mandatory for staging/production.


Revision E: PostgreSQL/Redis Assignment

Added to Sub-issue #80-B acceptance criteria:

PostgreSQL Logging:

  • Modify docker-compose.yml postgres environment with POSTGRES_LOG_CONFIG
  • Map LOG_LEVEL to log_statement: DEBUG=all, INFO=ddl, WARN=none, ERROR=none
  • Logs to Docker stdout/stderr

Redis Logging:

  • Modify docker-compose.yml redis environment with REDIS_LOGLEVEL
  • Map LOG_LEVEL: DEBUG=debug, INFO=verbose, WARN=notice, ERROR=warning
  • Logs to Docker stdout/stderr

Review Summary

Gate Verdict Key Findings
QR plan-completeness PASS_WITH_CONCERNS Missing dev defaults, Loki failure policy, risks
TW plan-scrub READY_WITH_REVISIONS Added Revisions A-E (see comment #892)
QR plan-code PASS_WITH_CONCERNS Add LOG_LEVEL validation, error handling
QR plan-docs NEEDS_CHANGES Container count clarification needed

Outstanding Items Addressed

QR plan-docs concerns resolved:

  1. Container Count Clarification:

    • Current: 6 containers (Traefik, Frontend, Backend, OCR, PostgreSQL, Redis)
    • After #80: 9 containers (+Promtail, +Loki, +Grafana)
    • README.md currently says "5-container" - this is a pre-existing error (OCR was added later)
    • Documentation update scope: 5→6 (current), then 6→9 (post-implementation)
  2. UX-DEBUGGING.md Scope:

    • Current content: Frontend Vite console config (out of sync)
    • Plan: REPLACE entirely with unified logging system docs
    • New doc covers: LOG_LEVEL per container, correlation IDs, Grafana access
    • Frontend debugging becomes a section within the new doc
  3. Documentation Acceptance Criteria (clarified):

    • LOG_LEVEL values: DEBUG, INFO, WARN, ERROR
    • Supported containers: All 6 application + OCR
    • Correlation ID field: requestId (UUID v4)
    • Grafana access: https://logs.motovaultpro.com or internal :3000

QR plan-code Fixes (incorporated into implementation)

  1. LOG_LEVEL Validation: Add validation with warning on invalid values
  2. Error Handling: Wrap frontend console calls in try-catch
  3. Type Safety: Use TypeScript string literal types for log levels

Final Plan Verdict

APPROVED FOR EXECUTION

All concerns have been addressed or have clear resolution paths during implementation. The plan is complete with:

  • 7 sub-issues with clear scope and dependencies
