2.alertmanager配置变更
参考URL：https://prometheus.io/docs/alerting/latest/configuration/#webhook_config
# vi /root/alertmanager/alertmanager.yml
global:
resolve_timeout: 5m
http_config: 代理环境，所以需要该全局配置；也可以设置在具体receivers下面
proxy_url: 'http://192.168.13.190:7777'
route:
group_by: ['alertname']
group_wait: 10s
group_interval: 10s
repeat_interval: 1m
receiver: 'rocketchat'
receivers:
- name: 'rocketchat'
webhook_configs:
- url: 'http://211.149.224.155:3000/hooks/ZanvEXd5t2Qaoycvm/Wwff7ndDeCq8DqFnaGhi4gdGWHpXJnaWyQoQzESypwwBvApJ'
send_resolved: true
主要配置的作用：
global: 全局配置，包括报警解决后的超时时间、SMTP 相关配置、各种渠道通知的 API 地址等等。
route: 用来设置报警的分发策略，它是一个树状结构，按照深度优先从左向右的顺序进行匹配。
receivers: 配置告警消息接受者信息，例如常用的 email、wechat、slack、webhook 等消息通知方式。
