在 prometheus alertmanager 通知中提及 slack 用户

Question

所以我有一个通用标签 opsteam，一旦 alertmanager 被解雇，它应该让 DM 处于松弛状态。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。

所以这是我的自定义松弛通知

是的，我的消息只是 slack 中的文本。
