Overview ¶
Package pprof serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool. For more information about pprof, see http://code.google.com/p/google-perftools/.
The package is typically only imported for the side effect of registering its HTTP handlers. The handled paths all begin with /debug/pprof/.
To use pprof, link this package into your program:
import _ "net/http/pprof"
Then use the pprof tool to look at the heap profile:
go tool pprof http://localhost:6060/debug/pprof/heap
Or to look at a 30-second CPU profile:
go tool pprof http://localhost:6060/debug/pprof/profile
Or to view all available profiles:
go tool pprof http://localhost:6060/debug/pprof/

Functions ¶
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 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.
