amazon-web-services - Grafana 中的 Kubernetes Pod 和节点没有数据点 - Prometheus Dashboard

Question

我将 Prometheus 作为服务运行:

admin1@POC-k8s-master:/tmp$ sudo systemctl status  prometheus
[sudo] password for admin1:
● prometheus.service - Prometheus Monitoring

Grafana 作为 K8s 对象:

请指导我解决这个问题!

由于 kube-system 中的 kube-state-metrics 未运行，数据现在即将到来!解决该问题后，它起作用了。感谢大家的帮助
