示例1: Meter

// Meter configures the database metrics collectors and
func (self *LDBDatabase) Meter(prefix string) {
	// Initialize all the metrics collector at the requested prefix
	self.getTimer = metrics.NewTimer(prefix + "user/gets")
	self.putTimer = metrics.NewTimer(prefix + "user/puts")
	self.delTimer = metrics.NewTimer(prefix + "user/dels")
	self.missMeter = metrics.NewMeter(prefix + "user/misses")
	self.readMeter = metrics.NewMeter(prefix + "user/reads")
	self.writeMeter = metrics.NewMeter(prefix + "user/writes")

	self.compReadMeter = metrics.NewMeter(prefix + "compact/input")
	self.compWriteMeter = metrics.NewMeter(prefix + "compact/output")

	// Create a quit channel for the periodic collector and run it
	self.quitLock.Lock()
	self.quitChan = make(chan chan error)
	self.quitLock.Unlock()

	go self.meter(3 * time.Second)
