I am installing Istio on my cluster, but I want to use my existing Prometheus and Grafana installations. I used the Helm chart from istio-installer, and I am seeing some strange behavior.
- I can install the dashboards–the
- If I install them to
istio-system, my grafana can’t pick them up. If I install them to
kube-system(where my prometheus is) Grafana can pick them up, but it can’t see any Istio metrics–the Istio Service Dashboard can’t read any of the namespaces on the cluster and none of my services show up in the menu.
What do I need to do to get these dashboards working in my existing Grafana?
