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

|
usage
|
|
-----
|
|
|
|
Enabling profiling in your application is as simple as one line at the top of your main function
|
|
|
|
```go
|
|
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.
|
|
|
|
```go
|
|
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](http://godoc.org/github.com/pkg/profile).
