📊 MONITORING & HEALTH CHECKS

System Health Monitoring:

# Check overall system health
curl http://localhost:7860/api/status

# Response:
{
  "status": "healthy",
  "timestamp": "2025-11-11T12:00:00Z",
  "database": "connected",
  "total_providers": 40,
  "online_providers": 38,
  "degraded_providers": 2,
  "offline_providers": 0,
  "uptime_seconds": 3600
}

Provider Status:

# Check individual provider health
curl http://localhost:7860/api/providers

# Response includes:
{
  "providers": [
    {
      "name": "CoinGecko",
      "category": "market_data",
      "status": "online",
      "response_time_ms": 125,
      "success_rate": 99.5,
      "last_check": "2025-11-11T12:00:00Z"
    },
    ...
  ]
}

Database Metrics:

# Check data freshness
curl http://localhost:7860/api/freshness

# Response shows age of data per source
{
  "market_data": {
    "CoinGecko": {"staleness_minutes": 0.5, "status": "fresh"},
    "Binance": {"staleness_minutes": 1.2, "status": "fresh"}
  },
  "news": {
    "CryptoPanic": {"staleness_minutes": 8.5, "status": "fresh"}
  }
}

---

🔧 CONFIGURATION OPTIONS

Schedule Intervals (in app.py startup):

interval_map = {
    'market_data': 'every_1_min',        # BTC/ETH/BNB prices
    'blockchain_explorers': 'every_5_min', # Gas prices, network stats
    'news': 'every_10_min',              # News articles
    'sentiment': 'every_15_min',         # Fear & Greed Index
    'onchain_analytics': 'every_5_min',  # On-chain metrics
    'rpc_nodes': 'every_5_min',          # Block heights
}

To modify:

1. Edit the interval_map in app.py (lines 123-131)
2. Restart the application
3. Changes will be reflected in schedule compliance tracking

Rate Limits (in config.py):

Each provider has configured rate limits:

• CoinGecko: 50 calls/minute
• Etherscan: 5 calls/second
• CoinMarketCap: 100 calls/hour
• NewsAPI: 200 calls/day

Warning alerts trigger at 80% usage.

🗃️ DATABASE MANAGEMENT

Database Location:

data/api_monitor.db

Backup Strategy:

# Manual backup
cp data/api_monitor.db data/api_monitor_backup_$(date +%Y%m%d).db

# Automated daily backup (add to crontab)
0 2 * * * cp /home/user/crypto-dt-source/data/api_monitor.db \
  /home/user/crypto-dt-source/data/backups/api_monitor_$(date +\%Y\%m\%d).db

# Keep last 30 days
find /home/user/crypto-dt-source/data/backups/ -name "api_monitor_*.db" \
  -mtime +30 -delete

Database Size Expectations:

• Day 1: ~10-20 MB
• Week 1: ~50-100 MB
• Month 1: ~100-500 MB (depending on data retention)

Data Retention:

Current configuration retains all historical data indefinitely. To implement cleanup:

# Add to monitoring/scheduler.py
def cleanup_old_data():
    """Remove data older than 90 days"""
    cutoff = datetime.utcnow() - timedelta(days=90)

    # Clean old connection attempts
    db_manager.delete_old_attempts(cutoff)

    # Clean old system metrics
    db_manager.delete_old_metrics(cutoff)

🔒 SECURITY BEST PRACTICES

✅ Already Implemented:

1. API Keys: Loaded from environment variables
2. Key Masking: Sensitive data masked in logs
3. SQLAlchemy ORM: Protected against SQL injection
4. CORS: Configured for cross-origin requests
5. Input Validation: Pydantic models for request validation

⚠️ Production Hardening (Optional but Recommended):

1. Add Authentication (if exposing to internet):

# Install dependencies
pip install python-jose[cryptography] passlib[bcrypt]

# Implement JWT authentication
# See: https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/

2. Enable HTTPS:

# Using Let's Encrypt with Nginx reverse proxy
sudo apt install nginx certbot python3-certbot-nginx

# Configure Nginx
sudo nano /etc/nginx/sites-available/crypto-hub

# Nginx config:
server {
    listen 80;
    server_name your-domain.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name your-domain.com;

    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;

    location / {
        proxy_pass http://localhost:7860;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

# Enable and test
sudo ln -s /etc/nginx/sites-available/crypto-hub /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

# Get certificate
sudo certbot --nginx -d your-domain.com

3. Firewall Configuration:

# Allow only necessary ports
sudo ufw allow 22/tcp    # SSH
sudo ufw allow 80/tcp    # HTTP
sudo ufw allow 443/tcp   # HTTPS
sudo ufw enable

4. Rate Limiting (Prevent abuse):

Add to app.py:

from slowapi import Limiter, _rate_limit_exceeded_handler
from slowapi.util import get_remote_address

limiter = Limiter(key_func=get_remote_address)
app.state.limiter = limiter
app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)

@app.get("/api/status")
@limiter.limit("10/minute")  # Max 10 requests per minute
async def get_status(request: Request):
    ...

---

📈 SCALING CONSIDERATIONS

Current Capacity:

• Concurrent WebSocket Connections: 50+ tested
• API Requests: ~500/minute (depending on provider rate limits)
• Database: SQLite handles ~100k records/month efficiently

When to Scale:

Migrate to PostgreSQL when:

• Database size > 1 GB
• Need multiple application instances
• Require advanced querying/analytics

# PostgreSQL setup
sudo apt install postgresql postgresql-contrib

# Update database/db.py connection string
DATABASE_URL = "postgresql://user:password@localhost/crypto_hub"

Add Redis Caching when:

• Response times > 500ms
• High read load on database
• Need distributed rate limiting

# Install Redis
sudo apt install redis-server

# Update config to use Redis for caching
pip install redis aioredis

Kubernetes Deployment for:

• High availability requirements
• Auto-scaling needs
• Multi-region deployment

🧪 TESTING YOUR DEPLOYMENT

1. Health Check:

curl http://localhost:7860/health

# Expected: {"status":"healthy","timestamp":"..."}

2. Database Verification:

# Check database exists
ls -lh data/api_monitor.db

# Query provider count
sqlite3 data/api_monitor.db "SELECT COUNT(*) FROM providers;"

# Expected: 40+ providers

3. API Functionality:

# Test market data
curl http://localhost:7860/api/status | jq

# Test provider health
curl http://localhost:7860/api/providers | jq

# Test WebSocket (using wscat)
npm install -g wscat
wscat -c ws://localhost:7860/ws/master

4. Data Collection Verification:

# Check recent data collections
sqlite3 data/api_monitor.db \
  "SELECT provider_id, category, actual_fetch_time FROM data_collections \
   ORDER BY actual_fetch_time DESC LIMIT 10;"

# Should show recent timestamps (last 1-15 minutes depending on schedule)

5. Scheduler Status:

curl http://localhost:7860/api/schedule | jq

# Check compliance:
# - on_time_count should be > 0
# - on_time_percentage should be > 80%

---

🐛 TROUBLESHOOTING

Common Issues:

1. "Database not found" error:

# Create data directory
mkdir -p data

# Restart application (database auto-initializes)
python app.py

2. "API key not configured" warnings:

# Check .env file exists
ls -la .env

# Verify API keys are set
grep -v "^#" .env | grep "KEY"

# Restart application to reload .env

3. High rate limit usage:

# Check current rate limits
curl http://localhost:7860/api/rate-limits

# If > 80%, reduce schedule frequency in app.py
# Change 'every_1_min' to 'every_5_min' for example

4. WebSocket connection fails:

# Check if port 7860 is open
netstat -tuln | grep 7860

# Check CORS settings in app.py
# Ensure your domain is allowed

5. Slow response times:

# Check database size
ls -lh data/api_monitor.db

# If > 500MB, implement data cleanup
# Add retention policy (see Database Management section)
