我在使用配置监控模块时收到警报prometheus/kube-prometheus-stack 25.1.0。

警报

[FIRING:1] KubeProxyDown - critical\nAlert: Target disappeared from Prometheus target discovery. - critical\n Description: KubeProxy has disappeared from Prometheus target discovery.\n Details:\n  \xe2\x80\xa2 alertname: KubeProxyDown\n  \xe2\x80\xa2 prometheus: monitoring/prometheus-kube-prometheus-prometheus\n  \xe2\x80\xa2 severity: critical\n

我认为这是一个新的默认规则kube-prometheus-stack 25.x.x。它不存在于prometheus/kube-prometheus-stack 21.x.x.

EKS 和 minikube 中也发生了同样的问题。

KubeProxyDown规则
