示例1: ProfileCmd
// ProfileCmd runs forever, sending Go runtime statistics to StatsD.
func ProfileCmd(stats metrics.Scope) {
stats = stats.NewScope("Gostats")
var memoryStats runtime.MemStats
prevNumGC := int64(0)
c := time.Tick(1 * time.Second)
for range c {
runtime.ReadMemStats(&memoryStats)
// Gather goroutine count
stats.Gauge("Goroutines", int64(runtime.NumGoroutine()))
// Gather various heap metrics
stats.Gauge("Heap.Alloc", int64(memoryStats.HeapAlloc))
stats.Gauge("Heap.Objects", int64(memoryStats.HeapObjects))
stats.Gauge("Heap.Idle", int64(memoryStats.HeapIdle))
stats.Gauge("Heap.InUse", int64(memoryStats.HeapInuse))
stats.Gauge("Heap.Released", int64(memoryStats.HeapReleased))
// Gather various GC related metrics
if memoryStats.NumGC > 0 {
totalRecentGC := uint64(0)
realBufSize := uint32(256)
if memoryStats.NumGC < 256 {
realBufSize = memoryStats.NumGC
}
for _, pause := range memoryStats.PauseNs {
totalRecentGC += pause
}
gcPauseAvg := totalRecentGC / uint64(realBufSize)
lastGC := memoryStats.PauseNs[(memoryStats.NumGC+255)%256]
stats.Timing("Gc.PauseAvg", int64(gcPauseAvg))
stats.Gauge("Gc.LastPause", int64(lastGC))
}
stats.Gauge("Gc.NextAt", int64(memoryStats.NextGC))
// Send both a counter and a gauge here we can much more easily observe
// the GC rate (versus the raw number of GCs) in graphing tools that don't
// like deltas
stats.Gauge("Gc.Count", int64(memoryStats.NumGC))
gcInc := int64(memoryStats.NumGC) - prevNumGC
stats.Inc("Gc.Rate", gcInc)
prevNumGC += gcInc
