# Grafana Integration Guide
This guide shows how to visualize your application metrics with Grafana using **real Prometheus**.
## Why Prometheus?
We've replaced custom tracking with actual Prometheus because:
-**Industry standard** - Battle-tested metrics collection
-**Rich ecosystem** - Thousands of existing dashboards
-**Better performance** - Optimized time-series storage
-**Less code** - No custom database or API endpoints
-**Standard metrics** - HTTP requests, response times, etc.
## Available Metrics
### Automatic Metrics (from echo-contrib/prometheus)
- `http_requests_total` - Total HTTP requests by method/status/endpoint
- `http_request_duration_seconds` - Request duration histogram
- `http_request_size_bytes` - Request size histogram
- `http_response_size_bytes` - Response size histogram
### Custom Application Metrics
- `knet_page_views_total{route="/"}` - Page views by route
- `knet_page_views_total{route="/draw"}` - Draw page views
- `knet_box_clicks_total{position="1"}` - Box clicks by position
- `knet_websocket_connections` - Active WebSocket connections
## Authentication
The `/metrics` endpoint uses **Basic Authentication** in production:
- **Username:** `api` (or set via `API_USERNAME` environment variable)
- **Password:** Your API token (set via `API_TOKEN` environment variable)
**Example:**
```bash
curl -u api:your-api-token http://your-server:54321/metrics
```
## Grafana Setup
### Prometheus Data Source (Recommended)
1. **Add Prometheus Data Source** in Grafana
2. **Set URL** to: `http://your-server:54321`
3. **Set Basic Auth**: Username: `api`, Password: `your-api-token`
4. **Set Scrape Interval**: 15s (Prometheus scrapes our `/metrics` endpoint)
That's it! Grafana will automatically discover all available metrics.
### Sample Dashboard Queries
**Traffic Overview:**
```promql
# Total requests per minute
rate(http_requests_total[1m]) * 60
# Page views
knet_page_views_total
# Request duration 95th percentile
histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))
# Error rate
rate(http_requests_total{status=~"4.."}[5m]) / rate(http_requests_total[5m]) * 100
```
**Application Metrics:**
```promql
# Box interactions
rate(knet_box_clicks_total[5m])
# Active WebSocket connections
knet_websocket_connections
# Most popular pages
topk(10, rate(knet_page_views_total[1h]))
```
## Dashboard Examples
### 1. HTTP Overview Panel
- **Metric:** `rate(http_requests_total[1m]) * 60`
- **Type:** Graph
- **Title:** "Requests per Minute"
### 2. Response Time Panel
- **Metric:** `histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))`
- **Type:** Single Stat
- **Title:** "95th Percentile Response Time"
### 3. Page Views Panel
- **Metric:** `knet_page_views_total`
- **Type:** Graph
- **Title:** "Page Views by Route"
### 4. Box Clicks Heatmap
- **Metric:** `rate(knet_box_clicks_total[5m])`
- **Type:** Graph
- **Title:** "Box Clicks per Second"
## Environment Variables
Set these for production:
```bash
export API_TOKEN="your-secure-api-token"
export API_USERNAME="api" # Optional, defaults to "api"
export BUILD_NUMBER="prod-v1.0" # Enables production mode
```
## Benefits of This Approach
1. **Standard Prometheus** - Works with all Grafana features
2. **Rich Metrics** - HTTP performance + custom business metrics
3. **No Database** - Prometheus handles storage and retention
4. **Better Performance** - Optimized time-series queries
5. **Alerting Ready** - Use Prometheus AlertManager
6. **Ecosystem** - Tons of existing dashboards and tools
## Persistent Storage Setup
### Option 1: Docker Compose (Recommended)
For persistent metrics storage, run a Prometheus server alongside your app:
```bash
# 1. Copy your API token to .env
cp .env.example .env
# Edit .env and set your API_TOKEN
# 2. Start the full monitoring stack
docker-compose up -d
# 3. Access services
# - Your app: http://localhost:54321
# - Prometheus: http://localhost:9090
# - Grafana: http://localhost:3000 (admin/admin)
```
**What this gives you:**
-**Persistent metrics** - Data survives restarts
-**30-day retention** - Configurable in docker-compose.yml
-**Grafana pre-configured** - Points to Prometheus automatically
-**Production ready** - Proper volumes and networking
### Option 2: Standalone Prometheus
If you prefer to run Prometheus separately:
```bash
# 1. Update prometheus.yml with your API token
# 2. Start Prometheus
prometheus --config.file=prometheus.yml --storage.tsdb.path=./prometheus_data
# 3. Configure Grafana to point to http://localhost:9090
```
### Grafana Data Source Configuration
With persistent Prometheus:
1. **Add Prometheus Data Source** in Grafana
2. **Set URL** to: `http://prometheus:9090` (Docker) or `http://localhost:9090` (standalone)
3. **No authentication needed** - Prometheus handles the API token
4. **Query retention**: Up to 30 days of historical data
## Quick Start
1. **Start your server:** `./tmp/main`
2. **Test metrics:** `curl -u api:your-token http://localhost:54321/metrics`
3. **Add Prometheus data source** in Grafana: `http://localhost:54321`
4. **Create dashboard** with queries like `http_requests_total`
5. **Enjoy real-time metrics!** 📊
Your analytics are now powered by industry-standard Prometheus! <20>

# Tracking API Documentation
The tracking service provides analytics about endpoint usage with time-based filtering.
## Authentication
In production, all tracking endpoints require Bearer token authentication:
```
Authorization: Bearer <your-api-token>
```
## Endpoints
### GET /api/tracking/stats
Get endpoint statistics with optional time period filtering.
**Query Parameters:**
- `period` (optional): `day`, `week`, `month`, `year`, `all` (default: `all`)
**Examples:**
```bash
# Get all-time stats
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/stats
# Get last week's stats
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/stats?period=week
# Get last 30 days
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/stats?period=month
```
**Response:**
```json
{
"stats": [
{
"endpoint": "/",
"method": "GET",
"hit_count": 245,
"unique_users": 89,
"last_access": "2025-08-13T10:30:00Z",
"first_access": "2025-08-06T14:22:00Z"
}
],
"period": "week",
"total_endpoints": 8
}
```
### GET /api/tracking/summary
Get overall tracking summary for a time period.
**Query Parameters:**
- `period` (optional): `day`, `week`, `month`, `year`, `all` (default: `all`)
**Examples:**
```bash
# Get today's summary
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/summary?period=day

"total_endpoints": 12,
"total_unique_users": 234,
"oldest_visit": "2025-08-13T00:15:00Z",
"newest_visit": "2025-08-13T23:45:00Z",
"tracking_active": true
}
```
### GET /api/tracking/trends
Get visit trends over time with configurable granularity.
**Query Parameters:**
- `granularity` (optional): `hour`, `day`, `week`, `month` (default: `day`)
- `period` (optional): `24h`, `7d`, `30d`, `1y` (default: `7d`)
**Examples:**
```bash
# Hourly trends for last 24 hours
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/trends?granularity=hour&period=24h
# Daily trends for last 30 days
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/trends?granularity=day&period=30d
# Weekly trends for last year
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/trends?granularity=week&period=1y
```
**Response:**
```json
{
"trends": [
{
"time_bucket": "2025-08-13",
"hits": 567,
"unique_users": 123,
"unique_endpoints": 8
},
{
"time_bucket": "2025-08-12",
"hits": 445,
"unique_users": 98,
"unique_endpoints": 7
}
],
"granularity": "day",
"period": "7d"
}
```
### GET /api/tracking/visits
Get recent individual visits with optional filtering.
**Query Parameters:**
- `limit` (optional): Number of visits to return (default: `50`)
**Example:**
```bash
curl -H "Authorization: Bearer $API_TOKEN" /api/tracking/visits?limit=20
```
**Response:**
```json
{
"visits": [
{
"user_hash": "a1b2c3d4e5f6...",
"endpoint": "/boxes",
"method": "GET",
"ip_address": "192.168.1.100",
"user_agent": "Mozilla/5.0...",
"referer": "https://google.com",
"timestamp": "2025-08-13T15:30:00Z"
}
],
"count": 20
}
```
## Benefits of This Approach
1. **No Duplication**: Single source of truth in `user_visits` table
2. **Flexible Querying**: Any time period can be queried on-demand
3. **Rich Analytics**: Detailed trends and user behavior insights
4. **Efficient Storage**: Only raw visits stored, stats calculated in real-time
5. **Historical Analysis**: Can analyze any historical period without pre-aggregation
## Performance Considerations
- Indexes are created on `timestamp`, `endpoint`, and `user_hash` for fast queries
- For very high traffic, consider adding materialized views for common time periods
- The SQLite database handles thousands of requests efficiently with proper indexing
