Enable Envoy Debugging

I’m using Istio 1.4.8. I would like to know how I can enable debugging for the Envoy proxy for Istio 1.4.8. I do not want to have to completely re-install the product, but just set a configuration that enables the debugging. Are the debugging messages written to the istio-proxy container and in any particular directory and file?

Do something like this:

kubectl exec -n <> <<pod_with_proxy>> – curl -X POST http://localhost:15000/logging?level=debug

Then get the logs from the istio-proxy pod:

kubectl logs -n <> <<pod_with_proxy>> istio-proxy -f

Thank you, Scott. That enabled all of the debugging. I appreciate it.
