更新2：我可以使用grafana和InfluxDB获取统计信息。但是，我觉得这有点矫枉过正。我希望看到我的集群的当前状态，而不是看到历史趋势。基于链接的图像，应该可以使用预部署的Heapster和Kubernetes Dashboard
更新1： 使用下面的命令，我确实看到了资源信息。我想问题的其余部分是为什么它没有出现（或者我应该如何配置它以显示）在kubernetes仪表板中，如下图所示：https://docs.giantswarm.io/img/dashboard-ui.png
$ kubectl cluster-info
Kubernetes master is running at https://[hidden].uksouth.cloudapp.azure.com
Heapster is running at https://[hidden].uksouth.cloudapp.azure.com/api/v1/namespaces/kube-system/services/heapster/proxy
KubeDNS is running at https://[hidden].uksouth.cloudapp.azure.com/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
kubernetes-dashboard is running at https://[hidden].uksouth.cloudapp.azure.com/api/v1/namespaces/kube-system/services/kubernetes-dashboard/proxy
tiller-deploy is running at https://[hidden].uksouth.cloudapp.azure.com/api/v1/namespaces/kube-system/services/tiller-deploy:tiller/proxy
我正在尝试监控Azure Kubernetes部署中的性能。我注意到它默认运行Heapster。我没有发布这个，但是如果它存在的话，确实想要利用它。我的问题是：我如何访问它，或者它有什么问题？以下是我能想到的细节，如果您需要更多，请告诉我。
$ kubectl proxy
Starting to serve on 127.0.0.1:8001
我设置了一个代理：
localhost:8001/api/v1/namespaces/kube-system/services/kubernetes-dashboard/proxy/#!/workload?namespace=default
将浏览器指向
404 page not found
我看到了kubernetes仪表板，但请注意我没有看到https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/显示的性能图表。我也没有看到管理部分。
然后我将浏览器指向localhost：8001 / api / v1 / namespaces / kube-system / services / heapster / proxy并获取
kubectl get pods --namespace=kube-system

答案 0 :(得分：1)
我在过去看到，如果重新启动仪表板，它就会开始工作。你能快点尝试一下，让我知道吗？
