pprof

README

This is a fork of net/http/pprof that doesn't use init side effects and doesn't use html/template (which ends up calling reflect.Value.MethodByName, which disables some linker deadcode optimizations).

Documentation

Overview

Package pprof serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool.

See Go's net/http/pprof for docs.

This is a fork of net/http/pprof that doesn't use init side effects and doesn't use html/template (which ends up calling reflect.Value.MethodByName, which disables some linker deadcode optimizations).

Functions

func AddHandlers

func AddHandlers(mux *http.ServeMux)

func Cmdline

func Cmdline(w http.ResponseWriter, r *http.Request)

Cmdline responds with the running program's command line, with arguments separated by NUL bytes. The package initialization registers it as /debug/pprof/cmdline.

func Handler

func Handler(name string) http.Handler

Handler returns an HTTP handler that serves the named profile.

func Index

func Index(w http.ResponseWriter, r *http.Request)

Index responds with the pprof-formatted profile named by the request. For example, "/debug/pprof/heap" serves the "heap" profile. Index responds to a request for "/debug/pprof/" with an HTML page listing the available profiles.

func Profile

func Profile(w http.ResponseWriter, r *http.Request)

Profile responds with the pprof-formatted cpu profile. Profiling lasts for duration specified in seconds GET parameter, or for 30 seconds if not specified. The package initialization registers it as /debug/pprof/profile.

func Symbol

func Symbol(w http.ResponseWriter, r *http.Request)

Symbol looks up the program counters listed in the request, responding with a table mapping program counters to function names. The package initialization registers it as /debug/pprof/symbol.

func Trace

func Trace(w http.ResponseWriter, r *http.Request)

Trace responds with the execution trace in binary form. Tracing lasts for duration specified in seconds GET parameter, or for 1 second if not specified. The package initialization registers it as /debug/pprof/trace.
