 The configured Prometheus add-on scrapes the following endpoints:
 
-1. *istio-mesh* (`istio-telemetry.istio-system:42422`): all Mixer-generated mesh
-   metrics.
-1. *istio-telemetry* (`istio-telemetry.istio-system:9093`): all Mixer-specific metrics. Used
-   to monitor Mixer itself.
-1. *envoy-stats* (`istio-proxy:15090`): raw stats generated by Envoy. Prometheus is configured to look for pods with the `envoy-prom` endpoint exposed. The add-on configuration filters out a large number of envoy metrics during collection in an attempt to limit the scale of data processed by the add-on.
-1. *pilot* (`istio-pilot.istio-system:9093`): all pilot metrics.
-1. *galley* (`istio-galley.istio-system:9093`): all galley metrics.
-1. *istio-policy* (`istio-policy.istio-system:9093`): all policy metrics.
