Enable HTTP log to capture the requestbody and headers in the log

[buddhinh]

I'm trying to enable headers and request body in linkerd-proxy HTTP log.

By default, LINKERD2_PROXY_LOG environmental variable in workload application linkerd-proxy container set as following, disabling headers and request body.

LINKERD2_PROXY_LOG: warn,linkerd=info,hickory=error,[{headers}]=off,[{request}]=off

I have tried to enable that by changing linkerd-config configmap.

Default parametes of linkerd-config configmap:

logHTTPHeaders: "off"
logLevel: warn,linkerd=info,hickory=error

Applied configmap parameters

logHTTPHeaders: "on"
logLevel: warn,linkerd=info,hickory=error

However, I have failed to loh headers and request body.

Is it possible to capture the requestbody and headers? What is the correct way to do that?
