```bash
# Blockchain health
curl http://localhost:8080/health

# Coordinator health
curl http://localhost:8011/health

# Marketplace health
curl http://localhost:8102/health
```

### Monitoring Script

```bash
#!/bin/bash
# health-check.sh

services=("blockchain:8080" "coordinator:8011" "marketplace:8102")

for service in "${services[@]}"; do
    name="${service%%:*}"
    port="${service##*:}"
    
    if curl -f "http://localhost:$port/health" > /dev/null 2>&1; then
        echo "✓ $name is healthy"
    else
        echo "✗ $name is unhealthy"
        # Send alert
    fi
done
```

### Systemd Health Monitoring

## Troubleshooting

### Common Issues

#### Service Won't Start

```bash
# Check logs
sudo journalctl -u aitbc-coordinator-api -n 50

# Check port conflicts
sudo netstat -tulpn | grep -E '8080|8011|8102'

# Check permissions
sudo -u aitbc ls -la /opt/aitbc
```

#### Database Connection Failed

```bash
# Check PostgreSQL status
sudo systemctl status postgresql

# Check connection
psql -h localhost -U aitbc -d aitbc

# Check firewall
sudo ufw status
```

#### GPU Not Detected

```bash
# Check GPU
nvidia-smi

# Check CUDA
nvcc --version

# Check driver
sudo dmesg | grep -i nvidia
```

### Performance Issues

#### High CPU Usage

```bash
# Check process CPU
top -p $(pgrep -f coordinator-api)

# Profile with cProfile
python -m cProfile -o profile.stats apps/coordinator_api/main.py
```

#### High Memory Usage

```bash
# Check memory
free -h

# Check process memory
ps aux | grep coordinator-api

# Check for memory leaks
valgrind --leak-check=full python apps/coordinator_api/main.py
```

### Network Issues

#### Connection Refused

```bash
