Enterprise-grade monitoring for AI agents and LLM applications built on Datadog's infrastructure platform. Provides end-to-end tracing, cost tracking, quality evaluations, and security detection across multi-agent workflows.
Datadog LLM Observability extends the established Datadog monitoring platform to cover AI agents and LLM applications. It provides end-to-end tracing across multi-agent workflows, token-level cost tracking, built-in quality and security evaluations, and cross-correlation with traditional infrastructure metrics — all within the same Datadog dashboard teams already use for APM and infrastructure monitoring.
The core capability is LLM span tracing. Every LLM call in your application generates a span that captures the prompt, completion, token counts, latency, model parameters, and estimated cost. These spans integrate with Datadog's existing APM traces, so you can see exactly how an LLM call fits into a broader request flow — from the user's HTTP request through your application logic, into the LLM call, and back. For multi-agent systems, this means full visibility into how requests flow through different agents, which agent made which LLM calls, and where bottlenecks occur.
