Overview

Package profiling allows accessing the pprof profiling data via the HTTP interface of the Go program. It provides an HTTP handler that can be registered to an HTTP router to expose pprof profiling data.

The tool pprof provides a way to analyze the performance of Go programs. It can be used to generate a profile of a Go program, display the profile in a web browser, and analyze the profile data.

For an example implementation, see the pkg/httpserver/config.go file.
