   查了下代码，每10s检测一下告警，但我更没有办法理解这里count的含义了。
   以默认告警配置为例：
   `  service_resp_time_rule:
       metrics-name: service_resp_time
       op: ">"
       threshold: 1000
       period: 10
       count: 3
       silence-period: 5
       message: Response time of service {name} is more than 1000ms in 3 minutes of last 10 minutes.`
   
   这里的count:3 为什么是指 响应时间在最近10分钟内有3分钟超过了1000ms，服务的吞吐比较高的话，每秒都有几十次请求，每个请求都有响应时间，这个3是如何对应到3分钟的呢？如果是指检测间隔的话，应该是30s才对吧
