Operations
Health Checks
# Check all components
kubectl get pods -n ai-hub
# Check vLLM
curl http://vllm.ai-hub.svc:8000/health
# Check Milvus
kubectl exec -it milvus-proxy-0 -n ai-hub -- curl localhost:9091/healthz
Troubleshooting
| Issue |
Cause |
Resolution |
| OOM on vLLM |
Model too large |
Increase GPU memory or use quantization |
| Slow retrieval |
Index not optimized |
Rebuild Milvus index |
| Empty responses |
No relevant chunks |
Check embedding quality |
| GPU not detected |
Driver issue |
Verify NVIDIA device plugin |
| Prompt injection |
Guardrails not configured |
Review NeMo Guardrails rules |
