# Subscribe to critical events
def handle_critical(event):
    print(f"ALERT: {event.description}")

watchdog_manager.subscribe_to_events(
    callback=handle_critical,
    event_filter=EventFilter(severities=[Severity.CRITICAL])
)

# Monitor health
health = watchdog_manager.get_health()
status = watchdog_manager.get_status()

# Graceful shutdown
await watchdog_manager.stop()
