Types

type M3Collector

type M3Collector struct {
	// contains filtered or unexported fields
}

M3Collector fulfills the metricCollector interface allowing users to ship circuit stats to a m3 backend. To use users must call InitializeM3Collector before circuits are started. Then register NewM3Collector with metricCollector.Registry.Register(NewM3Collector).

func (*M3Collector) Reset

func (g *M3Collector) Reset()

Reset is a noop operation in this collector.

func (*M3Collector) Update

Update is a callback by hystrix lib to relay the metrics to m3

type M3CollectorClient

type M3CollectorClient struct {
	// contains filtered or unexported fields
}

M3CollectorClient provides configuration that the m3 client will need.

func InitializeM3Collector

func InitializeM3Collector(scope tally.Scope) *M3CollectorClient

InitializeM3Collector creates the connection to the m3

func (*M3CollectorClient) NewM3Collector

func (m *M3CollectorClient) NewM3Collector(name string) metricCollector.MetricCollector

NewM3Collector creates a collector for a specific circuit. The prefix given to this circuit will be circuitbreaker.{metric}... Circuits with "/" in their names will have them replaced with ".".
