Two handlers are added to admin API to enable profiling and disable
profiling of a server in a standalone mode, or all nodes in the
distributed mode.
/minio/admin/profiling/start/{cpu,block,mem}:
- Start profiling and return starting JSON results, e.g. one
node is offline.
/minio/admin/profiling/download:
- Stop the on-going profiling task
- Stream a zip file which contains all profiling files that can
be later inspected by go tool pprof

profile
Simple profiling support package for Go
installation
go get github.com/pkg/profile
usage
Enabling profiling in your application is as simple as one line at the top of your main function
import "github.com/pkg/profile"
func main() {
defer profile.Start().Stop()
...
}
options
What to profile is controlled by config value passed to profile.Start. By default CPU profiling is enabled.
import "github.com/pkg/profile"
func main() {
// p.Stop() must be called before the program exits to
// ensure profiling information is written to disk.
p := profile.Start(profile.MemProfile, profile.ProfilePath("."), profile.NoShutdownHook)
...
}
Several convenience package level values are provided for cpu, memory, and block (contention) profiling.
For more complex options, consult the documentation.
