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/
