Usage

Eric Paris Jan 2015

Overview

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.

Options

-A, --all-namespaces=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.

-l, --selector=""
Selector (label query) to filter on, supports '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints.

--show-swap=false
Print pod resources related to swap memory.

--sort-by=""
If non-empty, sort pods list using specified field. The field can be either 'cpu' or 'memory'.

--sum=false
Print the sum of the resource usage

--use-protocol-buffers=true
Enables using protocol-buffers to access Metrics API.

--as-uid=""
