Description

The gateway still sends OTLP telemetry through www.braintrust.dev/api/pulse/otel, because the chart builds OTLP_HTTP_ENDPOINT from aiGateway.braintrustAppUrl. The API and Brainstore already send directly to pulse.braintrust.dev since image v2.20.0.

With the default app URL (https://www.braintrust.dev, with or without a trailing slash), the gateway now uses https://pulse.braintrust.dev/otel. A custom app URL keeps {appUrl}/api/pulse/otel, the same rule the code default uses. An empty global.controlPlaneTelemetry still sets no endpoint.

Testing

  • ./test.sh: passes (420 unit tests, rendering for all clouds, lint).
  • helm template with default, custom and empty values renders the endpoints above.

When aiGateway.braintrustAppUrl is the default https://www.braintrust.dev,
point OTLP_HTTP_ENDPOINT at https://pulse.braintrust.dev/otel instead of
going through www. Custom app URLs keep {appUrl}/api/pulse/otel.
