Send Langfuse alerts to PagerDuty

Mark Salpeter

Page your on-call team from Langfuse. Receive alerts, project notifications, and prompt changes as PagerDuty events.

PagerDuty can receive alert, project notification, or prompt change events from the automation configuration page in Langfuse.

Paste the routing key from a PagerDuty service and Langfuse pages whoever is on call when your LLM application misbehaves:

• Trigger a critical PagerDuty alert when an alert on p95 latency, cost, or evaluator scores crosses its threshold. The PagerDuty alert resolves on its own when the Langfuse alert recovers.
• Open an incident when a scheduled blob storage export fails or Langfuse deactivates an evaluator, by adding PagerDuty under Project Settings → Notifications.
• View prompt releases in your service's change timeline.

Both US and EU PagerDuty accounts are supported.
