- 3Site reliability and observability owners folding agent traces into the backend they already run, where OpenTelemetry support decides the work involved
How to choose AI Agent Observability
Start with what you are trying to see. If the open question is "what did the agent do on run 4,812", you want an agent-native trace: AgentOps, Laminar, Judgment, HoneyHive and Opik all record every step and let you replay it. If the open question is "will this change make the agent worse", you want simulation instead, and Okareo, Coval, Scorecard, LangWatch and Maxim all run scripted scenarios at an agent and score what comes back. Next decide where agent traces have to live. Teams that already run Datadog or send OpenTelemetry spans to one backend usually gain more from attaching agent traces to the stack they already watch than from a second window; Datadog Agent Observability and Pydantic Logfire are built for exactly that. Teams with no existing backend are freer to pick on the agent features alone. Then check data residency early. Laminar, OpenLIT and Future AGI publish an Apache 2.0 build you can run yourself, which matters because a trace holds the full text of everything the agent read and wrote. Finally, model the bill on your real run volume rather than the headline price. A free tier capped at 40,000 spans a month, a 30 dollar plan with 3 gigabytes included, and a 199 dollar plan with 125 simulations are three different ceilings, and the one you hit first is the number that decides the cost.
