+
+## <20><> Service Management Commands
+
+### Basic Operations
+```bash
+# List all AITBC services
+systemctl list-units --all | grep aitbc
+
+# Check service status
+systemctl status aitbc-coordinator-api.service
+
+# Start a service
+systemctl start aitbc-coordinator-api.service
+
+# Stop a service
+systemctl stop aitbc-coordinator-api.service
+
+# Restart a service
+systemctl restart aitbc-coordinator-api.service
+
+# Enable auto-start
+systemctl enable aitbc-coordinator-api.service
+
+# Disable auto-start
+systemctl disable aitbc-coordinator-api.service
+```
+
+### Bulk Operations
+```bash
+# Start all core services
+systemctl start aitbc-coordinator-api aitbc-blockchain-node aitbc-exchange-api aitbc-wallet
+
+# Restart all agent services
+systemctl restart aitbc-agent-* aitbc-ai-service
+
+# Check all services status
+systemctl status aitbc-*
+```
+
+## 📊 Service Monitoring
+
+### Health Checks
+```bash
+# Real-time monitoring
+watch -n 5 'systemctl status aitbc-* --no-pager'
+
+# Service failures
+journalctl -u aitbc-coordinator-api.service --since "1 hour ago" -p err
+
+# All service logs
+journalctl -f | grep aitbc
+```
+
+### Performance Monitoring
+```bash
+# Resource usage
+systemctl status aitbc-* | grep -E "(CPU|Memory)"
+
+# Service start times
+systemctl show aitbc-coordinator-api.service --property=ActiveEnterTimestamp
+
+# Dependency failures
+systemctl list-dependencies aitbc-coordinator-api.service
+```
+
+## 🔍 Troubleshooting
+
+### Common Issues
+
+#### Service Not Starting
+```bash
+# Check recent logs
+journalctl -u aitbc-service-name.service -n 20
+
+# Check for missing files
+systemctl cat aitbc-service-name.service | grep ExecStart
+
+# Verify working directory
+ls -la /path/to/working/directory
+```
+
+#### Python Module Errors
+```bash
+# Check PYTHONPATH
+systemctl cat aitbc-service-name.service | grep PYTHONPATH
+
+# Verify module exists
+python3 -c "import module.name"
+
+# Install missing dependencies
+pip3 install missing-package
+```
+
+#### Permission Issues
+```bash
+# Check file permissions
+ls -la /var/lib/aitbc/keystore/
+
+# Fix keystore permissions
+chmod 700 /var/lib/aitbc/keystore/
+chown root:root /var/lib/aitbc/keystore/
+```
+
+### Service-Specific Fixes
+
+#### Coordinator API
+```bash
+# Check environment files
+ls -la /home/oib/aitbc/apps/coordinator-api/.env
+
+# Verify Python path
+python3 -c "import sys; print(sys.path)"
+
+# Test manual startup
+cd /home/oib/aitbc/apps/coordinator-api
+PYTHONPATH=/home/oib/aitbc/apps/coordinator-api/src python3 -m uvicorn app.main:app --host 0.0.0.0 --port 8000
+```
+
+#### Blockchain Node
+```bash
+# Check data directory
+ls -la /var/lib/aitbc/data/
+
+# Verify configuration
+cat /opt/aitbc/apps/blockchain-node/.env.production
+
+# Test blockchain module
