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
|
|
|
|
```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)
|
|
...
|
|
// You can enable different kinds of memory profiling, either Heap or Allocs where Heap
|
|
// profiling is the default with profile.MemProfile.
|
|
p := profile.Start(profile.MemProfileAllocs, 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).
