Key strengths
- Datadog APM gives our team clear, actionable insights into application performance, helping us pinpoint bottlenecks and resolve issues faster—so we're always ahead of the curve.
- With powerful end-to-end tracing and intuitive dashboards, Datadog simplifies complex performance data, letting administrators identify root causes of problems quickly and accurately.
- As an analyst, I appreciate how smoothly Datadog integrates with our existing infrastructure. It reduces setup time significantly and lets us monitor everything from one centralized place.
- Debug LLM Failures Fast: Full call traces with inputs, outputs, latency, and token counts for every LLM call — no more guessing why an AI chain failed.
- Prevent Prompt Regressions: Automated evaluation runs on datasets catch quality regressions when prompts change, before they reach users.
- Monitor Production AI Quality: Real-time dashboards track LLM latency, error rates, and output quality — the same visibility layer backend engineers expect for APIs.
