kubernetes - Prometheus - 路由中使用的未定义接收器\"null\"

Question

为什么我在路由中使用了 receiver null？注释掉与 null 相关的路由仍然会产生相同的错误。

知道如何解决这个问题吗？配置看起来正确吗？它昨天确实有效，但我删除了所有内容并尝试重新安装，但我收到此错误。

失败:提供 alertmanager 配置:无法解析来自 Secret 的基本配置:路由中使用了未定义的接收器\"null\"

另外，如何为每个警报设置单独的电子邮件？当它工作时，它通常会发送一个摸索警报。我可以只禁用路线部分并且只有接收器吗？那会单独发送警报吗？ group_by: ['...'] 还是分组发送..

  config:
    global:
      resolve_timeout: 5m
    route:
      group_by: ['job']
      group_wait: 30s
      group_interval: 5m
      repeat_interval: 30m
      receiver: 'null'
      routes:
      - match:
          alertname: Watchdog
        receiver: 'null'
    receivers:
    - name: 'null'
    route:
      group_by: ['...']
      receiver: 'email-alert'
    receivers:
    - name: 'email-alert'
      email_configs:
      - to: test@gmail.com
        from: test@gmail.com
        smarthost: postfix.test-internal:25
        require_tls: false

这是日志条目:

在 YAML 中，null 和 "null" 不是一回事。

• null:代表NULL值
• "null":表示等于"null"的字符串。

尝试删除引号:

      routes:
      - match:
          alertname: Watchdog
        receiver: null
    receivers:
    - name: null
