- istio 1.8.5, installed via helm and enabled on a small subset of namespaces, labeled with istio.io/rev=1-8-5
→ Can’t use a newer version as our k8s clusters are still 1.16.x
- prometheus addon instance installed just for istio scraping
- Company-wide grafana 6.6.0, using the dashboards present on grafana.com
My doubt is regarding what I think may be “too much data” appearing on the Istio Mesh Dashboard. On the HTTP/gRPC Workloads table, grafana shows many workloads that aren’t “istio enabled” and end up showing up with NaN data. I even got a few “-” services.
Is this expected? Shouldn’t istio return only the services/workloads where it’s enabled?
Is there a way to restrict the scraping to the istio-enabled namespaces?
