top

Display Resource (CPU/Memory) usage.

The top command allows you to see the resource consumption for nodes or pods.

This command requires Metrics Server to be correctly configured and working on the server.

$ kubectl top

node

Show metrics for all nodes

kubectl top node

Show metrics for a given node

kubectl top node NODE_NAME

Display resource (CPU/memory) usage of nodes.

The top-node command allows you to see the resource consumption of nodes.

$ kubectl top node [NAME | -l label]

Name	Shorthand	Default	Usage
no-headers		false	If present, print output without headers
selector	l		Selector (label query) to filter on, supports ‘=’, ‘==’, and ‘!=’.(e.g. -l key1=value1,key2=value2)
sort-by			If non-empty, sort nodes list using specified field. The field can be either ‘cpu’ or ‘memory’.
use-protocol-buffers		true	Enables using protocol-buffers to access Metrics API.

Show metrics for all pods in the default namespace

kubectl top pod

Show metrics for all pods in the given namespace

kubectl top pod --namespace=NAMESPACE

Show metrics for a given pod and its containers

kubectl top pod POD_NAME --containers

Show metrics for the pods defined by label name=myLabel

kubectl top pod -l name=myLabel

Display resource (CPU/memory) usage of pods.

The ‘top pod’ command allows you to see the resource consumption of pods.

Due to the metrics pipeline delay, they may be unavailable for a few minutes since pod creation.

$ kubectl top pod [NAME | -l label]

Name	Shorthand	Default	Usage
all-namespaces	A	false	If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with —namespace.
containers		false	If present, print usage of containers within a pod.
field-selector			Selector (field query) to filter on, supports ‘=’, ‘==’, and ‘!=’.(e.g. —field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type.
no-headers		false	If present, print output without headers.
selector	l		Selector (label query) to filter on, supports ‘=’, ‘==’, and ‘!=’.(e.g. -l key1=value1,key2=value2)
sort-by			If non-empty, sort pods list using specified field. The field can be either ‘cpu’ or ‘memory’.
use-protocol-buffers		true	Enables using protocol-buffers to access Metrics API.
