type MetricsCollector ¶

type MetricsCollector interface {
	IncrementCounter(name string, labels ...string)
	RecordHistogram(name string, value float64, labels ...string)
	RecordGauge(name string, value float64, labels ...string)
	StartTimer(name string) Timer
}

MetricsCollector defines the interface for collecting metrics. This should match the server.MetricsCollector interface.

type NoOpMetricsCollector ¶

type NoOpMetricsCollector struct{}

NoOpMetricsCollector implements the server.MetricsCollector interface with no operations. It will be used in tests where metrics collection is not the focus. server.MetricsCollector expects:

IncrementCounter(name string, labels ...string)
RecordHistogram(name string, value float64, labels ...string)
RecordGauge(name string, value float64, labels ...string)
StartTimer(name string) server.Timer

func NewNoOpMetricsCollector() *NoOpMetricsCollector

func (c *NoOpMetricsCollector) IncrementCounter(name string, labels ...string)

func (c *NoOpMetricsCollector) RecordGauge(name string, value float64, labels ...string)

func (c *NoOpMetricsCollector) RecordHistogram(name string, value float64, labels ...string)

func (c *NoOpMetricsCollector) StartTimer(name string) server.Timer

type Timer ¶

type Timer interface {
	Stop() float64
}
