Functions ¶

func ExampleHTTP ¶

func ExampleHTTP()

ExampleHTTP is an example of HTTP exposure of Go profiles. Read more in "Efficient Go"; Example 9-5.

func Write ¶

func Write(profileOutPath string) error

Write saves the profile of the currently open file descriptors in to file in pprof format.

Types ¶

type File ¶

type File struct {
	*os.File
}

File is a wrapper on os.File that tracks file descriptor lifetime.

func CreateTemp ¶

func CreateTemp(dir, pattern string) (*File, error)

func Open ¶

func Open(name string) (*File, error)

Open opens file and tracks it in the `fd` profile`. NOTE(bwplotka): We could use finalizers here, but explicit Close is more reliable and accurate. Unfortunately it also changes type which might be dropped accidentally.

func (*File) Close ¶

func (f *File) Close() error

Close closes files and updates profile.
