Langfuse
Connect a Langfuse project so Tensile can import selected traces for workflow discovery and review.
Connect an existing Langfuse project when your agent traces are already stored there. Tensile reads traces and observations through the Langfuse API and maps them into sessions and events for the workspace. It does not require you to re-instrument the same agent just to import those records.
Connect a project
- In Langfuse, create an API key pair for the project. Copy the public key, secret key, and the host for your Langfuse instance.
- In Tensile, open Settings → Connections → Langfuse. An organization owner or admin can manage connections.
- Enter the Host, Public key, and Secret key. For an existing connection, leave the secret field blank to keep the saved key.
- Optionally set the Customer-id metadata key (default
customer_id) and Backfill from date. Leave the date blank to request all available history. - Select Connect or Update and use the connection status in Settings to follow synchronization.
The secret key is used by the server-side connector. Keep it out of source control, browser code, and support messages. Use credentials with only the access needed to read the selected project.
What is imported
Tensile maps Langfuse traces into sessions and observations into events. Trace and observation identifiers are retained as source references where available; the configured customer-id metadata key can be used to associate a downstream customer. Exact fields depend on the data present in the Langfuse project.
Imported traces can support workflow discovery and evidence review. Connecting Langfuse does not approve a pack or activate evaluator-pack scoring. See Evaluator packs for the review and validation gates.
