Project Observability Analyzer

Analyze project structure and recommend observability strategy for applications.

Workflow

1. Scan Project Structure (files, dependencies, framework)
2. Detect Framework (Express, Next.js, FastAPI, Spring Boot, etc.)
3. Identify Existing Logging (Winston, Pino, Python logging, etc.)
4. Detect Existing Observability (Prometheus exporters, OTEL, APM agents)
5. Analyze API Endpoints (if web framework detected)
6. Generate Recommendations:

- OTEL instrumentation points - Logging library configurations - Prometheus metrics to add - Docker compose integration

1. Generate Integration Files:

- Updated docker-compose.yml (app + observability) - OTEL instrumentation code - Logger configuration - README with setup instructions

Example Output

## Project: Express.js REST API

**Framework**: Express.js 4.18.2
**Logging**: Winston (JSON format) ✅
**Observability**: None ❌

**Recommendations**:
1. Add express-prom-bundle for Prometheus metrics
2. Configure Winston → Loki (via Alloy)
3. Add OTEL auto-instrumentation for tracing
4. Integrate with LGTM stack

**Files Generated**:
- docker-compose-with-app.yml
- otel-instrumentation.js
- winston-loki-config.js

Framework Templates

• Express.js integration
• Next.js integration
• FastAPI integration
• Spring Boot integration
