在 prometheus alertmanager 通知中提及 slack 用户

【中文标题】在 prometheus alertmanager 通知中提及 slack 用户

【英文标题】：mention slack users in prometheus alertmanager notification

【发布时间】：2021-11-25 04:37:28

【问题描述】：

所以我有一个通用标签opsteam，一旦 alertmanager 被解雇，它应该会让 DM 陷入松弛状态。但是在 slack 中，我得到的用户名是纯文本，没有突出显示，这些用户也没有收到任何消息。

nodeSelector: 
  prometheus: "true"
enabled: true
retention: "30d"
extraFlags:
  - web.enable-lifecycle
  - web.enable-admin-api
strategy:
  type: RollingUpdate
global:
  scrape_interval: 30s
  external_labels:
    env: prod
    client: client
    cluster: project-prod-eks
    opsteam: "@U0325FRAD @U01GN7KJHU"

如果我将opsteam: "@U0325FRAD @U01GN7KJHU" 更改为opsteam: "@john @jim"，它也没有任何效果。

这是我的自定义 slack 通知

      range .Alerts

          - end -
       else -

是的，我的消息只是松弛的文本。

在 Slack 中嵌入用户名有一种给定的格式。https://api.slack.com/reference/surfaces/formatting#mentioning-users
