## Services Managed

### 1. Neuromorphic Security Service
- **Script**: `commsops/neuromorphic_security.py`
- **Description**: Real-time spiking neural network anomaly detection
- **Monitoring**: Specialized event listener for security context

### 2. DataOps Integration Service  
- **Script**: `commsops/dataops_integration.py`
- **Description**: Cross-domain integration with Atlas' DataOps infrastructure
- **Dependencies**: DragonFlyDB (port 18000)

### 3. NATS-Pulsar Bridge Service
- **Script**: `commsops/nats_pulsar_bridge.py`
- **Description**: Bidirectional messaging bridge between NATS and Apache Pulsar
- **Dependencies**: NATS (port 4222), Pulsar (port 6650)

## Usage

### Starting Services
```bash
# Start supervisord
supervisord -c /data/adaptai/platform/signalcore/ops/supervisor/supervisord.conf

# Control services using wrapper
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh status
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh restart neuromorphic-security

# Tail logs
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh logs neuromorphic-security
```

### Service Management
```bash
# Enhanced status view
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh status

# Restart all services
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh restart-all

# Individual service control
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh start neuromorphic-security
/data/adaptai/platform/signalcore/ops/supervisor/bin/supervisorctl_wrapper.sh stop dataops-integration
```

### Log Management
- Logs rotate daily with 30-day retention for service logs
- Error logs have 15-day retention
- Logs are compressed and managed by logrotate
- Custom event listeners provide enhanced monitoring

## Configuration Details

### Supervisord Features
- **Socket-based communication**: `/tmp/supervisor.sock`
- **Event listeners**: Process state monitoring and 60-second ticks
- **Log management**: Structured logging with rotation
- **Service recovery**: Automatic restart with backoff

### Service Configuration
- **Autostart**: All services start automatically
- **Autorestart**: Services restart on failure
- **Stop timeout**: Graceful shutdown periods configured
- **Log capture**: Stdout/stderr captured with rotation

### Security Considerations
- Services run as root (container environment)
- Log files have appropriate permissions
- Event listeners provide security context awareness
- No external network exposure required

## Integration with Container Environment

This infrastructure is designed for deployment in a container environment on vast.a1 (India-1xH200) with:
- **No systemd**: Uses supervisord for process management
- **Bare metal compatibility**: No Docker/K8s dependencies
- **Resource awareness**: Memory and CPU constraints considered
- **Network isolation**: Localhost-only service binding

## Monitoring and Events

### Event Types Handled
- `PROCESS_STATE`: Service state changes (start, stop, crash)
- `TICK_60`: Periodic 60-second events for maintenance

### Custom Event Listeners
- **General listener**: `event_listener.py` for all services
- **Neuromorphic monitor**: Specialized security context handling
- **Extensible**: Additional listeners can be added for specific services

## Log Rotation

### Service Logs
- **Rotation**: Daily or 100MB size limit
- **Retention**: 30 days for service logs, 15 days for error logs
- **Compression**: Enabled with delay
- **Post-rotation**: Custom handler for notifications

### Supervisor Logs  
- **Rotation**: Daily or 20MB size limit
- **Retention**: 15 days
- **Management**: Separate from service logs

## Troubleshooting

### Common Issues
1. **Socket not found**: Ensure supervisord is running with correct config
2. **Service not starting**: Check Python script existence and permissions
3. **Log rotation issues**: Verify logrotate configuration and permissions

### Debug Commands
```bash
# Check supervisor status
supervisorctl -c /data/adaptai/platform/signalcore/ops/supervisor/supervisord.conf status

# Check logs directly
tail -f /data/adaptai/platform/signalcore/ops/supervisor/logs/services/neuromorphic-security.log

# Test service scripts directly
python3 /data/adaptai/platform/signalcore/commsops/neuromorphic_security.py
```

## Maintenance

### Regular Tasks
- Monitor log file sizes and rotation
- Review event listener outputs
- Verify service health through wrapper commands
- Update configurations as services evolve

### Backup Considerations
- Supervisor configurations should be included in backups
- Log retention policies should align with backup strategies
- Service scripts are versioned in main repository
