# System and Monitoring

OpenViking provides system health, observability, and debug APIs for monitoring component status.

## API Reference

### health()

Basic health check endpoint. No authentication required.

**Python SDK**

```python
import openviking as ov

client = ov.OpenViking(path="./data")
client.initialize()

# Check if system is healthy
if client.observer.is_healthy():
    print("System OK")

client.close()
```

**HTTP API**

```
GET /health
```

```bash
curl -X GET http://localhost:1933/health
```

```bash
openviking health
```

**Response**

```json
{
  "status": "ok"
}
```

---

### status()

Get system status including initialization state and user info.

**Python SDK**

```python
import openviking as ov

client = ov.OpenViking(path="./data")
client.initialize()

print(client.observer.system)

client.close()
