(base) savilahao@bogon ~ % helm install prometheus prometheus-community/kube-prometheus-stack -n monitoring --create-namespace
NAME: prometheus
LAST DEPLOYED: Wed May 20 14:54:39 2026
NAMESPACE: monitoring
STATUS: deployed
REVISION: 1
DESCRIPTION: Install complete
TEST SUITE: None
NOTES:
kube-prometheus-stack has been installed. Check its status by running:
  kubectl --namespace monitoring get pods -l "release=prometheus"
  # ======================Grafana登陆与port转发教程===============
Get Grafana 'admin' user password by running:

  kubectl --namespace monitoring get secrets prometheus-grafana -o jsonpath="{.data.admin-password}" | base64 -d ; echo

Access Grafana local instance:
  export POD_NAME=$(kubectl --namespace monitoring get pod -l "app.kubernetes.io/name=grafana,app.kubernetes.io/instance=prometheus" -oname)

  kubectl --namespace monitoring port-forward $POD_NAME 3000

Get your grafana admin user password by running:

 
  kubectl get secret --namespace monitoring -l app.kubernetes.io/component=admin-secret -o jsonpath="{.items[0].data.admin-password}" | base64 --decode ; echo


Visit https://github.com/prometheus-operator/kube-prometheus for instructions on how to create & configure Alertmanager and Prometheus instances using the Operator.

如helm创建后指导所示看密码： kubectl get secret --namespace monitoring -l app.kubernetes.io/component=admin-secret -o jsonpath="{.items[0].data.admin-password}" | base64 --decode ; echo ^ebfc61

 prometheusEnabled: true
 prometheusServiceDiscovery: true

Q1:prometheusEnabled: true说明什么？在 Agones 中开启这个配置，它的实际意思是：Agones Controller 在代码层面启动了一个内置的 HTTP Server（通常是 8080 端口的 /metrics 路径），并且开始以 Prometheus 能看懂的纯文本格式往外“吐”数据（比如当前有多少个游戏服）。 Q2:prometheusServiceDiscovery: true 是干嘛的？简答：做服务发现—— 原生 Kubernetes 早期是用 Annotations（注解）来做服务发现的。开启这个，Agones 会给自己的 Pod 打上类似 prometheus.io/scrape: "true" 的标签。意思是：“嗨，如果有谁在收集监控数据，请来这里抓我。”
