Describe the solution that you would like.

I found that mux doesn't have the ability to integrate tracing and metrics by default and there doesn't seem to be a best practice in the documentation on how to monitor mux applications. Our project(https://github.com/alibaba/opentelemetry-go-auto-instrumentation) allows tracing and metrics(will be supported later) to be collected and reported on the mux app without making changes to user code. I was wondering if it would be possible for me to add an observable subsection to the official documentation for this project that describes best practices for observing the mux application. Thanks!
