  • kubectl top查看k8s pod的cpu , memory使用率情况

    To see the pods that use the most cpu and memory you can use the kubectl top command but it doesn’t sort yet and is also missing the quota limits and requests per pod. You only see the current usage:

    $ kubectl top pod --all-namespaces
    NAMESPACE NAME CPU(cores) MEMORY(bytes)
    kube-system kube-proxy-gke-rel3170-default-pool-3459fe6a 2m 12Mi
    kube-system kube-proxy-gke-rel3170-default-pool-3459fe6a 2m 12Mi
    kube-system fluentd-gcp-v2.0.9-5t9q6 8m 85Mi
    kube-system fluentd-gcp-v2.0.9-pd4s9 10m 84Mi
    kube-system kube-dns-3468831164-v2gqr 1m 26Mi
    kube-system event-exporter-v0.1.7-1642279337-180db 0m 13Mi
    kube-system kube-proxy-gke-rel3170-default-pool-3459fe6a 1m 12Mi
    kube-system l7-default-backend-3623108927-tjm9z 0m 1Mi
    kube-system kube-dns-3468831164-cln0p 1m 25Mi
    kube-system fluentd-gcp-v2.0.9-sj3rh 9m 84Mi
    kube-system kube-dns-autoscaler-244676396-00btn 0m 7Mi
    kube-system kubernetes-dashboard-1265873680-8prcm 0m 18Mi
    kube-system heapster-v1.4.3-3980146296-33tmw 0m 42Mi

    Because of these limitations, but also because you want to gather and store this resource usage information on an ongoing basis, a monitoring tool comes in handy. This allows you to analyze resource usage both in real time and historically, and also lets you alert on capacity bottlenecks.

    实际示例:

    [root@]:~# kubectl top  pod   -n taobao-spider 
    NAME                                                      CPU(cores)   MEMORY(bytes)
