企业微信对接 Alertmanager

Alertmanager 将告警信息推送到微信群，主要涉及到如下几方面的配置：

  1. 企业微信后台的配置，包括新建告警部门和应用；
  2. Alertmanager 的主配置文件配置和告警模板配置；
  3. Prometheus 主配置文件的配置以及告警规则的配置；

配置

官方文档：https://prometheus.io/docs/alerting/latest/configuration/#wechat_config

获取企业微信信息

  • 企业 ID
  • 然后在通讯录中，添加一个子部门，用于接收告警信息，获取部门 ID
  • 告警 AgentId 和 Secret 获取是需要在企业微信后台，【应用管理】中，自建应用才能够获得的
