Functions ¶

func InMicroseconds ¶

func InMicroseconds(d time.Duration) float64

Types ¶

type Adder ¶

type Adder func(float64, ...string)

func (Adder) Int ¶

func (a Adder) Int(x int, s ...string)

Int adds the value of `x`; convenience func for adding integers.

type Counter ¶

type Counter func(...string)

type Harness ¶

type Harness func(func() error, ...string) error

Harness funcs execute the given func and record metrics concerning the execution. The error returned from the harness is the same error returned from the execution of the func param.

func NewHarness ¶

func NewHarness(counts, errors Counter, timed Watcher, clock func() time.Time) Harness

NewHarness generates and returns an execution harness that records metrics. `counts` and `errors` are required; `timed` and `clock` must either both be nil, or both be non-nil.

type Watcher ¶

type Watcher func(float64, ...string)

func (Watcher) Since ¶

func (w Watcher) Since(t time.Time, s ...string)

Since records an observation of time.Now().Sub(t) in microseconds
