普罗米修斯规则不适用

Question

我在配置Prometheus规则时遇到了麻烦。

PrometheusRules.yml：

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  labels:
    prometheus: example
    role: alert-rules
  name: prometheus-example-rules
spec:
  groups:
    - name: example-rules
      rules:
        - alert: ExampleAlert
          expr: base_memory_usedHeap_bytes{quantile="0.5"} > 1

Prometheus.yml

apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  name: main
spec:
  serviceAccountName: prometheus
  replicas: 1
  serviceMonitorSelector:
    matchLabels:
      team: frontend
  ruleSelector:
    matchLabels:
      role: alert-rules
      prometheus: example
  resources:
    requests:
      memory: 400Mi

Prometheus无法加载规则。我想知道PrometheusRules配置是否有问题？现在，我只想有一个简单的“ hello word”规则。

谢谢！
