Monitor Retrieval and Grounding Health
Watch retrieval latency, hit quality, and grounding-related failures that degrade GenAI answer quality.
WHAT
Monitor retrieval performance and grounding-related health for RAG and cached GenAI paths.
HOW
- Track vector query latency and error rates.
- Monitor semantic cache hit ratio.
- Correlate poor grounding / user quality with retrieval empty results.
Key points
- Retrieval latency metrics
- Cache hit vs miss
- Grounding / relevance signals
- Vector search health
- Quality regressions from retrieval
Exam focus
Retrieval and cache health are first-class ops signals — slow or empty retrieval shows up as quality and latency regressions.
