For a LangChain or LangGraph app, turning on LangSmith tracing takes two environment variables and no code changes.
Sampling and conditional tracing, tested 7. Sampling and conditional tracing, tested Sampling decides how many traces you send. LangSmith vs. Langfuse vs. OpenTelemetry: LangSmith is the shortest path if you are all-in on LangChain or LangGraph.
Key takeaways
- How much does LangSmith cost per trace?
- How long does LangSmith keep traces?
- Base traces are kept for 14 days.
Is LangSmith the only way to trace LangChain?
