出现问题:时间不一致（如下类似）
Warning! Detected 457.83 seconds time difference between your browser and the server. Prometheus relies on accurate time and time drift might cause unexpected query results.
解决办法：
我自己吧服务器时间同步至 time1.aliyun.com
ntpdate time1.aliyun.com
然后把电脑的时间也同步至time1.aliyun.com 即可解决
l global：全局配置
l alerting：告警配置
l rule_files：告警规则
