pprof

README

Use the pprof tool

Then use the pprof tool to look at the heap profile:

go tool pprof http://localhost:9999/debug/pprof/heap

Or to look at a 30-second CPU profile:

go tool pprof http://localhost:9999/debug/pprof/profile

Or to look at the goroutine blocking profile, after calling runtime.SetBlockProfileRate in your program:

go tool pprof http://localhost:9999/debug/pprof/block

Or to collect a 5-second execution trace:

wget http://localhost:9999/debug/pprof/trace?seconds=5
