How to get CPU usage of Envoy (istio-proxy) container from another container in the POD

POD consist: my-app-container and envoy (istio-proxy) container

I want to get cpu_usage of envoy-container from may-app-container.

Info from: http://localhost:1500/stats and http://localhost:1500/stats/prometheus doesn't contain CPU_usage.

Thanks

Solution

  • Below are 2 ways I could find to get the information about istio-proxy cpu usage.

    You can use kubectl top.

    kubectl top pods -A --containers | grep istio-proxy | grep Mi
