I have a Service Mesh with several GRPC services and I would like to gather some more context over the current metrics provided by Istio. I have not found the request method information among the metrics’ tags and such information would be really handy to have.
I have been doing some research but could not find a way to add this information to the metrics. The more promising piece of information I found was the manifest named ‘namespace-metrics’ at Istio / Telemetry which looks like it should be adding that information to the Istio metrics. However, adding that manifest to the istio-system namespace (aiming at enabling it for all the cluster) did not do anything.
Is there any way to get this information in the metrics?
I have installed Istio v1.13.3 through the Helm charts (base, istiod and gateway) in a Kubernetes cluster v1.21.12.
