Collect metrics in development

We'll use a fully-fledged docker image with statsd, influxdb, grafana and sqlite in it.

Types ¶

type Dispatcher ¶

type Dispatcher interface {
	// Send will dispatch the metric.
	Send(Event) error

	// Close terminates potential persistent connections.
	Close() error
}

Dispatcher is the interface used by all metric implementations.

func NewNoopDispatcher ¶

func NewNoopDispatcher() Dispatcher

NewNoopDispatcher creates a new noop dispatcher instance.

func NewStatsdDispatcher ¶

func NewStatsdDispatcher(prefix, statsdAddr string) (Dispatcher, error)

NewStatsdDispatcher creates a new statsd dispatcher instance.

type Event ¶

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

Event represents a metric in the system.

func Count ¶

func Count(name string, value int, kvs ...KV) Event

Count generates a count metric representing a value in the system. Processed requests is an example of a counter.

func Gauge ¶

func Gauge(name string, value float64, kvs ...KV) Event

Gauge generates a gauge metric representing a measure at a given time. Request time or concurrent connections are examples of gauges.

type KV ¶

type KV struct {
	K string
	V interface{}
}

KV represents a tag for a particular metric.
