Azure Kubernetes 部署中缺少 Kubernetes 仪表板中的性能指标
Performance metrics in Kubernetes Dashboard missing in Azure Kubernetes deployment
更新 2：我能够使用 grafana 和 influxDB 获取统计信息。但是，我觉得这太过分了。我想查看集群的当前状态，而不是查看历史趋势。根据链接的图像，应该可以通过使用预部署的 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显示（或者我应该如何配置它显示）在 kubernetes 仪表板中，如下图所示：https://docs.giantswarm.io/img/dashboard-ui.png
$ kubectl top node
NAME CPU(cores) CPU% MEMORY(bytes) MEMORY%
k8s-agentpool0-41204139-0 36m 1% 682Mi 9%
k8s-agentpool0-41204139-1 33m 1% 732Mi 10%
k8s-agentpool0-41204139-10 36m 1% 690Mi 10%

我正在尝试监控我的 Azure Kubernetes 部署的性能。我注意到它默认有 Heapster 运行。我没有推出这个，但如果它在那里，我想利用它。我的问题是：我怎样才能访问它，或者它有什么问题？这是我能想到的详细信息，如果您需要更多，请告诉我。

将我的浏览器指向

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/ 处显示的性能图表。我也没有看到管理部分。
