<strong>How we cut our NLQ agent debugging time from hours to minutes with LLM Observability (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Datadog's Cloud Cost Management team significantly cut natural language query (NLQ) agent debugging time from hours to minutes—a roughly 20x reduction—by implementing LLM Observability. This was achieved through the use of curated datasets, component-level evaluators, and LLM traces to precisely identify root causes in their agent, which generates Datadog metrics queries.
