title: Difference between GaugeService and CounterService at Springboot Actuator
body: <p>I have an example project to use GaugeService and CounterService,</p>
  
  <p>I have realized that GaugeService keeps last value submitted, but I am expecting it will be calculated in a way of rolling append.</p>
  
  <p>So with this case GaugeService threads like CounterService.
  GaugeService  has only submit() method exposed no other configuration settings found. </p>
  
  <p>What is the difference between GaugeService and CounterService?</p>
