Functions ¶

func Gauge ¶

func Gauge(ctx context.Context, name string, value float32, rate float32, tags []string) error

func Histogram ¶

func Histogram(ctx context.Context, name string, value float32, rate float32, tags []string) error

func Inc ¶

func Inc(ctx context.Context, name string, value int64, rate float32, tags []string) error

func Runtime ¶

func Runtime(stats Stats)

Runtime enters into a loop, sampling and outputing the runtime stats periodically.

func SampleEvery ¶

func SampleEvery(stats Stats, t time.Duration)

SampleEvery enters a loop, sampling at the specified interval

func Timing ¶

func Timing(ctx context.Context, name string, value time.Duration, rate float32, tags []string) error

func WithStats ¶

func WithStats(ctx context.Context, stats Stats) context.Context

WithStats returns a new context.Context with the Stats implementation embedded.

func WithTags ¶

func WithTags(ctx context.Context, tags []string) context.Context

WithTags will return a context.Context where all metrics recorded with the embedded Stats implementation will include the given stats.

Types ¶

type Dogstatsd ¶

type Dogstatsd struct {
	*statsd.Client
}

Dogstatsd provides an implementation of the Stats interface backed by dogstatsd.

func NewDogstatsd ¶

func NewDogstatsd(addr string) (*Dogstatsd, error)

NewDogstatsd returns a new Dogstatsd instance that sends statsd metrics to addr.

func (*Dogstatsd) Gauge ¶

func (s *Dogstatsd) Gauge(name string, value float32, rate float32, tags []string) error

func (*Dogstatsd) Histogram ¶

func (s *Dogstatsd) Histogram(name string, value float32, rate float32, tags []string) error

func (*Dogstatsd) Inc ¶

func (s *Dogstatsd) Inc(name string, value int64, rate float32, tags []string) error

func (*Dogstatsd) Timing ¶

func (s *Dogstatsd) Timing(name string, value time.Duration, rate float32, tags []string) error

type Stats ¶

type Stats interface {
	Inc(name string, value int64, rate float32, tags []string) error
	Timing(name string, value time.Duration, rate float32, tags []string) error
	Gauge(name string, value float32, rate float32, tags []string) error
	Histogram(name string, value float32, rate float32, tags []string) error
}

Stats provides an interface for generating instruments, like guages and counts.

func FromContext ¶

func FromContext(ctx context.Context) (Stats, bool)

FromContext returns the Stats implementation that's embedded in the context.

type Statsd ¶

type Statsd struct {
	// contains filtered or unexported fields
}

Statsd is an implementation of the Stats interface backed by statsd.

func NewStatsd ¶

func NewStatsd(addr, prefix string) (*Statsd, error)

NewStatsd returns a new Statsd implementation that sends stats to addr.

func (*Statsd) Gauge ¶

func (s *Statsd) Gauge(name string, value float32, rate float32, tags []string) error

func (*Statsd) Histogram ¶

func (s *Statsd) Histogram(name string, value float32, rate float32, tags []string) error

func (*Statsd) Inc ¶

func (s *Statsd) Inc(name string, value int64, rate float32, tags []string) error

func (*Statsd) Timing ¶

func (s *Statsd) Timing(name string, value time.Duration, rate float32, tags []string) error
