使用--count指定探测的次数，命令如下：

./mc ping local1 --count 5

探测5次后，自动停止，控制台的输出，如下：

  1: http://192.168.0.109:9000:9000   min=0.45ms     max=0.45ms     average=0.45ms     errors=0   roundtrip=0.45ms

  3: http://192.168.0.109:9000:9000   min=0.45ms     max=0.80ms     average=0.65ms     errors=0   roundtrip=0.80ms
  4: http://192.168.0.109:9000:9000   min=0.45ms     max=0.80ms     average=0.63ms     errors=0   roundtrip=0.58ms
  5: http://192.168.0.109:9000:9000   min=0.45ms     max=0.80ms     average=0.63ms     errors=0   roundtrip=0.63ms

使用--count指定探测的次数，同时使用--interval指定探测之间的时间间隔，命令如下：

./mc ping local1 --count 5 --interval 2

探测5次后，自动停止，控制台的输出，如下：

  1: http://192.168.0.109:9000:9000   min=0.55ms     max=0.55ms     average=0.55ms     errors=0   roundtrip=0.55ms

  3: http://192.168.0.109:9000:9000   min=0.55ms     max=0.74ms     average=0.65ms     errors=0   roundtrip=0.65ms
