Types

type ClientInterface

type ClientInterface interface {
	// Gauge measures the value of a metric at a particular time.
	Gauge(name string, value float64, tags []string, rate float64) error

	// Count tracks how many times something happened per second.
	Count(name string, value int64, tags []string, rate float64) error

	// Close the client connection.
	Close() error

	// import "github.com/udhos/groupcache_exporter/groupcache/modernprogram"
	// cache := ... // create groupcache group
	// groupStat := modernprogram.New(cache)
	//
	Groups []groupcache_exporter.GroupStatistics
