Runtime Observability ​

The Observer API reports immediate status for queues, the vector database, models, locks, retrieval, and the file system.

Observer API ​

The observer API provides detailed component-level monitoring.

observer.queue ​

2. Interface and Parameters ​

No parameters.

3. Usage Examples ​

GET /api/v1/observer/queue
bash
curl -X GET http://localhost:1933/api/v1/observer/queue \
  -H "X-API-Key: your-key"

print(client.observer.queue())
# Output:
# [queue] (healthy)
