查看Prometheus 报错误：context deadline exceeded

加大各个node-exporter-5fkt7资源限制：
limits:
cpu: 200m
memory: 400Mi

在安装配置文件nodeExporter-daemonset.yaml中！

serviceMonitor/monitoring/node-exporter

https://172.16.192.227:9100/metrics
Get “https://172.16.192.227:9100/metrics”: context deadline exceeded

grep -rn “requests:” /root/kube-prometheus/manifests

加大资源限制：
[root@china ~]# vim /root/kube-prometheus/manifests/nodeExporter-daemonset.yaml

    resources:
      limits:
        cpu: 200m
        memory: 400Mi
      requests:
        cpu: 10m
        memory: 20Mi

从新配置：
[root@china manifests]# pwd
/root/kube-prometheus/manifests
[root@china manifests]# kubectl create -f .
