Overview ¶
Go port of Coda Hale's Metrics library
<https://github.com/msaf1980/go-metrics>
Coda Hale's original work: <https://github.com/codahale/metrics>
Example ¶
c := NewCounter() Register("money", c) c.Add(17) // Threadsafe registration // t := GetOrRegisterTimer("db.get.latency", nil) // t.Time(func() {}) // t.Update(1) fmt.Println(c.Count()) // fmt.Println(t.Min())

Variables ¶
var ErrUnsortedWeights = errors.New("unsorted weights")
var ( RuntimeNames struct { MemStats struct { Alloc string BuckHashSys string Frees string HeapAlloc string HeapIdle string HeapInUse string HeapObjects string HeapReleased string HeapSys string LastGC string Lookups string Mallocs string MCacheInUse string MCacheSys string MSpanInuse string MSpanSys string NextGC string NumGC string GCCPUFraction string // PauseNs Histogram PauseTotalNs string StackInUse string StackSys string Sys string TotalAlloc string } NumCgoCall string NumGoroutine string NumThread string } )
var UseNilMetrics bool = false
UseNilMetrics is checked by the constructor functions for all of the standard metrics. If it is true, the metric returned is a stub.
This global kill-switch helps quantify the observer effect and makes for less cluttered pprof profiles.
Functions ¶
func CaptureRuntimeMemStats ¶
Capture new values for the Go runtime statistics exported in runtime.MemStats. This is designed to be called as a goroutine.
func CaptureRuntimeMemStatsOnce ¶
func CaptureRuntimeMemStatsOnce()
Capture new values for the Go runtime statistics exported in runtime.MemStats. This is designed to be called in a background goroutine. Giving a registry which has not been given to RegisterRuntimeMemStats will panic.
Be very careful with this because runtime.ReadMemStats calls the C functions runtime·semacquire(&runtime·worldsema) and runtime·stoptheworld() and that last one does what it says on the tin.
func Each ¶
func Each(f func(name, tags string, tagsMap map[string]string, i interface{}) error, minLock bool) error
Call the given function for each registered metric.
func Get ¶
func Get(name string) interface{}
