Trace LangGraph application using LangSmith

Tracing LangGraph using the native LangSmith is best if you want a quick and simple setup focused solely on LangSmith's observability features, with no additional code changes required.

Perform the following steps on the same machine as the Secure Agent.

1Navigate to the latest AIAgentRuntime package path:

<Secure Agent installation directory>/downloads/package-AIAgentRuntime.<latest version>/package

2Locate and edit startup.sh to add the following environment variables:

export LANGSMITH_TRACING=true
export LANGSMITH_API_KEY=<your-api-key>
export LANGSMITH_ENDPOINT="https://api.smith.langchain.com"
export LANGSMITH_PROJECT=<project name>

Note: If you didn't create a custom project, you can omit the "export LANGSMITH_PROJECT=<project name>" line. LangSmith will then use the default project named "default".

Your startup.sh file should look like the following image:

3Restart the Secure Agent.
