If you’re already using the **Pangolin stack with Traefik as your reverse proxy**, you have powerful routing in place. But raw log files and scattered metrics make it difficult to truly understand traffic patterns.

The **Enhanced Traefik Log Dashboard** adds **real-time monitoring, OpenTelemetry support, and geolocation analytics**, giving you a full picture of your traffic.

## Features

* **OpenTelemetry OTLP Support**: Real-time traces from Traefik v3+
* **Hybrid Monitoring**: Combine OTLP traces with traditional log parsing
* **Geolocation**: MaxMind GeoIP integration with automatic updates
* **Analytics**: Live request rates, response times, error tracking
* **Production Ready**: Resource limits, health checks, optimized GC/memory

## Prerequisites

* Docker + Docker Compose
* Traefik v3.0+ (for OTLP) or v2.x (logs only)
* A working Pangolin stack

## Step 1: Configure Traefik

### For OTLP + Logs (Recommended)

Update `./config/traefik/traefik_config.yml`:

```yaml
log:
  level: INFO
  filePath: "/var/log/traefik/traefik.log"
  format: json

accessLog:
  filePath: "/var/log/traefik/access.log"
  format: json

tracing:
  otlp:
    http:
      endpoint: "http://log-dashboard-backend:4318/v1/traces"
  sampleRate: 0.1 # Adjust as needed - 0.1 for 10% sampling
  globalAttributes:
    environment: "production"
    service.version: "v3.0"
    deployment.environment: "pangolin"
```

### For Logs Only

```yaml
log:
  level: INFO
  filePath: "/var/log/traefik/traefik.log"

accessLog:
  filePath: "/var/log/traefik/access.log"
  format: json
```

## Step 2: Add Dashboard Services

Extend your existing `docker-compose.yml` with:

```yaml
  log-dashboard-backend:
    image: ghcr.io/hhftechnology/traefik-log-dashboard-backend:latest
    container_name: log-dashboard-backend
    restart: unless-stopped
    ports:
      - "4317:4317"   # OTLP gRPC
      - "4318:4318"   # OTLP HTTP
    volumes:
      - ./config/traefik/logs:/logs:ro
      - ./config/maxmind:/maxmind:ro
    environment:
      - PORT=3001
      - TRAEFIK_LOG_FILE=/logs/access.log
      - OTLP_ENABLED=true
      - OTLP_GRPC_PORT=4317
      - OTLP_HTTP_PORT=4318
      - USE_MAXMIND=true
      - MAXMIND_DB_PATH=/maxmind/GeoLite2-City.mmdb
      - MAXMIND_FALLBACK_ONLINE=true
      - GOGC=50
      - GOMEMLIMIT=500MiB

  log-dashboard-frontend:
    image: ghcr.io/hhftechnology/traefik-log-dashboard-frontend:latest
    container_name: log-dashboard-frontend
    restart: unless-stopped
    ports:
      - "3000:80"
    environment:
      - BACKEND_SERVICE=log-dashboard-backend
      - BACKEND_PORT=3001
    depends_on:
      - log-dashboard-backend
```

## Step 3: Setup MaxMind GeoIP (Optional but Recommended)

1. Create a free MaxMind account → [GeoLite2 signup](https://www.maxmind.com/en/geolite2/signup)
2. Generate a license key
3. Create directory:

```bash
mkdir -p ./config/maxmind
export MAXMIND_LICENSE_KEY=your_key_here
```

4. (Optional) Add updater service:

```yaml
  maxmind-updater:
    image: alpine:latest
    container_name: maxmind-db-updater
    volumes:
      - ./config/maxmind:/data
    environment:
      - MAXMIND_LICENSE_KEY=${MAXMIND_LICENSE_KEY}
    command: >
      sh -c "
        apk add --no-cache wget tar &&
        cd /data &&
        wget -O GeoLite2-City.tar.gz 'https://download.maxmind.com/app/geoip_download?edition_id=GeoLite2-City&license_key=$MAXMIND_LICENSE_KEY&suffix=tar.gz' &&
        tar -xzf GeoLite2-City.tar.gz --strip-components=1 '*/GeoLite2-City.mmdb' &&
        rm -f GeoLite2-City.tar.gz
      "
```

## Step 4: Launch Stack

```bash
docker compose up -d
docker compose ps
```

## Step 5: Access the Dashboard

* **Frontend UI** → [http://localhost:3000](http://localhost:3000)

## Key Features

* **Real-time statistics** (requests, response times, error rates)
* **Interactive world map** (request origins via MaxMind)
* **Service insights** (performance by router/service)
* **Hybrid monitoring** (OTLP + logs together)

## Performance Tuning

For production or high-traffic environments, you may want to adjust settings to optimize resource usage and throughput.

### Reduce OTLP Sampling
Lower sampling to avoid overwhelming storage and dashboards:

```yaml
tracing:
  sampleRate: 0.1  # 10% sampling in production
````

### Prefer gRPC over HTTP

For lower latency and higher throughput, enable gRPC instead of HTTP:

```yaml
tracing:
  otlp:
    grpc:
      endpoint: "log-dashboard-backend:4317"
      insecure: true
```

### Tune Backend Memory

Set environment variables in `log-dashboard-backend`:

```yaml
environment:
  - GOGC=20        # More aggressive garbage collection
  - GOMEMLIMIT=1GiB # Hard memory limit
```

### Resource Limits

Add CPU and memory constraints to containers:

```yaml
deploy:
  resources:
    limits:
      cpus: "1.0"
      memory: 512M
    reservations:
      cpus: "0.2"
      memory: 128M
```

These adjustments help keep the dashboard responsive while minimizing resource overhead.


## Troubleshooting

* **OTLP not showing** → Check Traefik `tracing` config + ports `4317/4318`
* **Logs not loading** → Ensure Traefik logs in JSON, volume mounted correctly
* **GeoIP errors** → Verify `MAXMIND_LICENSE_KEY` and DB path
* **Maxmind download errors** → Check license key validity by trying url with key directly in your browser
* **Docker logs for Traefik not showing** →  Use `docker exec -it traefik tail -f /var/log/traefik/traefik.log` instead of `docker logs traefik -f` to see real-time logs on the command line.
