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
