## Usage Examples

### Submit Events for Detection

```python
from mahavishnu.patterns.incident_response import (
    IncidentManager,
    IncidentEvent,
    IncidentSeverity,
)
from datetime import UTC, datetime

manager = IncidentManager(config)
await manager.start()

# Submit events
event = IncidentEvent(
    event_id="evt_001",
    timestamp=datetime.now(tz=UTC),
    event_type="error",
    source="api",
    severity=IncidentSeverity.HIGH,
    message="API error occurred",
)
await manager.submit_event(event)

# Check for incidents
incidents = await manager.check_for_incidents()
```

### Process Incident Through Workflow

```python
# Process incident automatically
result = await manager.process_incident(incident)
assert result.status == IncidentStatus.RESOLVED
```

### View Incident Statistics

```python
stats = manager.get_statistics()
print(f"Total incidents: {stats['total_incidents']}")
print(f"Active incidents: {stats['active_incidents']}")
print(f"By severity: {stats['by_severity']}")
```
