Observability & evaluation
Langfuse
Connect the project that captures your agent traces and sessions.
Before you start
Open the settings for the Langfuse project you want to connect and obtain its public and secret API keys. Use keys from the same project.
You’ll also need access to the Ollive account where you want to save this connection.
Connection fields
| Field | Requirement | What to enter |
|---|---|---|
| Public key | Required | Your project public key (pk-lf-…). |
| Secret key | Required | The matching project secret key (sk-lf-…). |
| Host | Optional | The base URL of your Langfuse instance. For regional or self-hosted instances, enter the host used by your project. |
Connect Langfuse
Sign in to Ollive and open Integrations. Select Langfuse.
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
A successful test confirms access to the project. Review the agents discovered from its trace data. If no agents appear, confirm that the project has recent agent traces, then refresh its assets.
Troubleshooting
- Authentication failed: check the credential values, account or project, and whether the key has expired or been revoked.
- Access denied: confirm that the key has permission to access the provider data used by the connection.
- Could not reach provider: check any host or server URL you entered. For private instances, confirm network access with your team.
- 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.
