E2E Correlation

Explore APM in Splunk

In this step, you will review what the full APM end-to-end correlation looks like in Splunk Observability Cloud.

Verify in Splunk APM #

Explore Trace #

1. From RUM session - Open the trace linked from RUM OR (paste the trace ID from the traceparent header or completed purchase request in the UI)

You will see a RUM correlation hyperlink that will take you to the RUM session from previous step.

Explore Service Map #

1. Navigate to APM → Service Map
2. Filter environment: workshop-$INSTANCE
3. Confirm all services appear with traffic edges:
   • frontend-api → catalog-api
   • frontend-api → order-api (via gateway)
   • frontend-api → payment-gateway → payment-api
   • payment-api → fulfillment-worker (via RabbitMQ)

This shows the expected E2E correlation across all the service and infrastructure layers.
