From the pod label name=cpu-user，find pods running high CPU workloads and write the name of the pod consuming most CPU to the file /opt/KUTR00401/KUTR00401.txt （which already exists）.
| kubectl top [flags] [options] | 显示资源（CPU/内存/存储）的使用情况。 |
#查看cpu使用率
$ kubectl config use-context k8s
$ kubectl top pod -l name=cpu-user -A
NAMAESPACE NAME CPU MEM
delault cpu-user-1 45m 6Mi
delault cpu-user-2 38m 6Mi
delault cpu-user-3 35m 7Mi
delault cpu-user-4 32m 10Mi
$ echo 'cpu-user-1' >>/opt/KUTR00401/KUTR00401.txt
#或者使用筛选
$ for i in `kubectl top pod -l name=cpu-user -A |awk '{if (NR > 1){print $1}}'|sort |uniq `;do echo $i >>/opt/KUTR00401/KUTR00401.txt;done
