如何在稳定/普罗米修斯图表values.yaml中设置普罗米修斯规则？ [英] How to set prometheus rules in stable/prometheus chart values.yaml?

问题描述

使用官方普罗米修斯图表稳定/普罗米修斯。

自定义其 values.yaml 文件以设置 alertmanager.yml 文件和 serverFiles 区域。

Customized its values.yaml file to set alertmanager.yml file and serverFiles area.

在规则下：{} ：

https://github.com。 com / kubernetes / charts / blob / master / stable / prometheus / values.yaml＃L598

它是 {} 。

例如，我尝试过：

  serverFiles:
    alerts: {}
    rules:
    # Alert for any instance that is unreachable for >5 minutes.
    - alert: InstanceDown
      expr: up == 0
      for: 5m
      labels:
        severity: page
      annotations:
        summary: "Instance {{ $labels.instance }} down"
      description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minutes."

然后运行 $ helm install my_prometheus 。然后pod出现了此错误：

And ran $ helm install my_prometheus. Then pod got this error:

PersistentVolumeClaim is not bound: "sweet-terrier-prometheus-server"
Back-off restarting failed container
Error syncing pod

推荐答案

serverFiles:
  alerts:
    groups:
    - name: NodeAlerts
      rules:
      - alert: NodeCPUUsage
        expr: (100 - (avg(irate(node_cpu{mode="idle"}[5m])) BY (instance) * 100)) > 75
        for: 2m
        labels:
          severity: alert
        annotations:
          description: '{{$labels.instance}}: CPU usage is above 75% (current value is:
            {{ $value }})'
          summary: '{{$labels.instance}}: High CPU usage detect

规则用于记录规则，警报用于警报规则。

rules are for record rules, alert is for alert rules.
