🐛 Troubleshooting

Common Issues

Service won't start:

# Check port conflicts
netstat -tulpn | grep :8001

# Check dependencies
docker ps | grep -E "(postgres|redis|influx)"

# Check logs
journalctl -u foxhunt-trading-engine

High latency:

# Check CPU affinity
taskset -c 0-3 cargo run --release --bin trading-engine

# Check system performance
htop
iostat 1

Market data issues:

# Test external connectivity
curl https://api.polygon.io/v2/aggs/ticker/AAPL/prev
ping fix.icmarkets.com

# Check WebSocket connections
ss -tuln | grep :8003

Log Locations

# Service logs (systemd)
/var/log/foxhunt/trading-engine.log
/var/log/foxhunt/risk-management.log

# Application logs (structured JSON)
tail -f logs/application.log | jq .

# Error logs
tail -f logs/error.log
