Observability & evaluation
LangSmith
Connect the workspace where you log runs, threads and feedback.
Before you start
In LangSmith, go to Settings → API Keys and create a key. Check whether your workspace is in the US, the EU, or self-hosted.
You’ll also need access to the Ollive account where you want to save this connection.
Connection fields
| Field | Requirement | What to enter |
|---|---|---|
| API key | Required | Your LangSmith API key (lsv2_…). |
| Host | Optional | Leave it empty for LangSmith Cloud in the US. For the EU, use https://eu.api.smith.langchain.com. For self-hosted, use your own address. |
Connect LangSmith
Sign in to Ollive and open Integrations. Select LangSmith.
Give the connection a recognizable name, especially if you connect multiple accounts or projects.
Enter the credential fields listed above.
Choose Test connection. Resolve any error, then select Connect to save the connection.
Verify your setup
When the test passes, Ollive can see your projects. Check that it is the workspace with the runs you expect.
Troubleshooting
- Authentication failed: check the values you entered, that they are for the right account or project, and that the key hasn’t expired or been revoked.
- Access denied: check that the key has permission to read the data Ollive needs.
- Could not reach provider: check any host or server URL you entered. For a private instance, check with your team that Ollive can reach it.
- Rate limited: wait before retrying the test.
Still stuck? Contact support with the provider name and error message. Keep API keys and secrets out of your message.
