Here is my network model(injected):
client send requests --> ingressgateway --> service_A --> service_B -->service_C
When I search for the mertics "istio_requests_total" on prometheus, I can only see the data of service_A. I can only get empty query result when I filter destination_workload="service_C".
The data I want to get is the requests between service_B and service_C. I can see that the requests data I want is in the service_C istio proxy's log, but how do I add it to the metrics?
My istio version is 1.10.6.
