karmadactl top node
Display resource (CPU/memory) usage of nodes
Synopsis
Display resource (CPU/memory) usage of nodes in member clusters.
The top-node command allows you to see the resource consumption of nodes.
karmadactl top node [NAME | -l label]
Examples
# Show metrics for all nodes in the default namespace
karmadactl top node
# Show metrics for all nodes in the default namespace in member1 cluster
karmadactl top node --clusters=member1
# Show metrics for all nodes in the default namespace in member1 and member2 cluster
karmadactl top node --clusters=member1,member2
# Show metrics for all nodes in the given namespace
karmadactl top node --namespace=NAMESPACE
# Show metrics for the nodes defined by label name=myLabel
karmadactl top node -l name=myLabel
Options
--clusters strings Used to specify target member clusters, for example: --clusters=member1,member2
-h, --help help for node
--karmada-context string The name of the kubeconfig context to use
--kubeconfig string Path to the kubeconfig file to use for CLI requests.
--no-headers If present, print output without headers
-l, --selector string Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching objects must satisfy all of the specified label constraints.
--show-capacity Print node resources based on Capacity instead of Allocatable(default) of the nodes.
--sort-by string If non-empty, sort nodes list using specified field. The field can be either 'cpu' or 'memory'.
--use-protocol-buffers Enables using protocol-buffers to access Metrics API. (default true)
Options inherited from parent commands
--add-dir-header If true, adds the file directory to the header of the log messages
--alsologtostderr log to standard error as well as files (no effect when -logtostderr=true)
--log-backtrace-at traceLocation when logging hits line file:N, emit a stack trace (default :0)
--log-dir string If non-empty, write log files in this directory (no effect when -logtostderr=true)
--log-file string If non-empty, use this log file (no effect when -logtostderr=true)
--log-file-max-size uint Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
--logtostderr log to standard error instead of files (default true)
--one-output If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
--skip-headers If true, avoid header prefixes in the log messages
--skip-log-headers If true, avoid headers when opening log files (no effect when -logtostderr=true)
--stderrthreshold severity logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=true) (default 2)
-v, --v Level number for the log level verbosity
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
