kubernetes - 如何使用配置文件使 Prometheus Alertmanager 静音？

Question

我用的是官方stable/prometheus-operator chart 确实使用 helm 部署 Prometheus。

到目前为止，它运行良好，除了烦人的 CPUThrottlingHigh为许多 Pod(包括自己的 Prometheus 的 config-reloaders containers)触发的警报。此警报是 currently under discussion ，我想暂时关闭它的通知。

Alertmanager 有一个 silence feature ，但它是基于网络的:

Silences are a straightforward way to simply mute alerts for a given time. Silences are configured in the web interface of the Alertmanager.

有一种方法可以使来自 CPUThrottlingHigh 的通知静音使用配置文件？

Answer 1

一种选择是将您想要静音的警报路由到“空”接收器。在 alertmanager.yaml :

route:
  # Other settings...
  group_wait: 0s
  group_interval: 1m
  repeat_interval: 1h

  # Default receiver.
  receiver: "null"

  routes:
  # continue defaults to false, so the first match will end routing.
  - match:
      # This was previously named DeadMansSwitch
      alertname: Watchdog
    receiver: "null"
  - match:
      alertname: CPUThrottlingHigh
    receiver: "null"
  - receiver: "regular_alert_receiver"

receivers:
  - name: "null"
  - name: regular_alert_receiver
