我有Prometheus运算符,它的按预期的方式工作
https://github.com/coreos/prometheus-operator

现在我想从头开始应用alert manager

阅读文档后,即时通讯就出现了这些Yaml。
但是问题是当我进入用户界面时
什么都没显示,我在这里想念什么吗?

http://localhost:9090/alerts
我使用端口转发...

这是all我已应用于我的k8s集群的配置文件
我只想做一些简单的测试,看看它是否有效,然后将其扩展到我们的需求...
alertmanger_main.yml

receivers:

  webhook_configs:

并创建我使用的 secret
kubectl create secret generic alertmanager-main --from-file=alertmanager.yaml
我需要的是K8S中的一些基本警报,我遵循了文档说明但没有找到任何循序渐进的好教程

当我点击浏览器
38.482.152.331:9093
38.482.152.331:30904

什么都没发生...

最佳答案

当您考虑使用AlertManager时,除了常规配置和应用警报规则外,AlertManager还需要与Prometheus服务器集成。然后,Prometheus实例可以跟踪任何传入的一系列事件,并且一旦检测到任何可识别的规则,就会向嵌套的alertmanager触发警报。

为了启用警报,可能有必要在Prometheus实例上附加以下配置:

alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - 'alertmanagerIP:9093'

具体来说,对于CoreOS中的AlertManager实现,您可以按照Alerting官方文档中描述的步骤进行操作;但是,下面您可以从上述指南中找到有关Prometheus Pod警报配置的示例:
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  name: example
spec:
  replicas: 2
  alerting:
    alertmanagers:
    - namespace: default
      name: alertmanager-example
      port: web
  serviceMonitorSelector:
    matchLabels:
      team: frontend
  resources:
    requests:
      memory: 400Mi
  ruleSelector:
    matchLabels:
      role: prometheus-rulefiles
      prometheus: example
