Upstream cluster metrics in sidecars

I’m trying to get visibility into connection stats from the sidecar to the local service. I expected that these would show up as a cluster under envoy stats, but the only upstream cluster that ever shows up in my envoy stats is the xds-grpc cluster. Am I looking in the wrong place or for the wrong metric name?

You need to enable more metrics through annotations, see

Ah yes! Exactly what I was looking for. I knew that istio telemetry wasn’t collecting all of the stats from envoy, but I didn’t realize that not all the stats were even enabled on envoy. Thank you!
