"content": "The charts on this dashboard are intended to show Istio main components cost in terms of resources utilization under steady load.\n\n- **vCPU / 1k rps:** shows vCPU utilization by the main Istio components normalized by 1000 requests/second. When idle or low traffic, this chart will be blank. The curve for istio-proxy refers to the services sidecars only.\n- **vCPU:** vCPU utilization by Istio components, not normalized.\n- **Memory:** memory footprint for the components. Telemetry and policy are normalized by 1k rps, and no data is shown when there is no traffic. For ingress and istio-proxy, the data is per instance.\n- **Bytes transferred / sec:** shows the number of bytes flowing through each Istio component.\n\n\n",
