Explore your kube resource usage and allocation.
-
Display historical statistical resource usage from StackDriver.
-
List resource QoS allocation to pods in a cluster. Inspired by:
-namespace- Limit the query to the specified namespace (defaults to all)-sort- Field to sort by-reverse- Reserve the sort order-historical- Display historical resource data-cpu- Show historical cpu data-mem- Show historical memory data-duration- The duration to use for historical data (default to 4h)-project- The GCloud project id (required for historical)-workers- Number of workers to run for historical-csv- Export results to CSV file
To use the historical functionality you must set the
GOOGLE_APPLICATION_CREDENTIALS environment variable. See below for more

Show aggregate resource requests and limits. This is the same information
displayed by kubectl describe nodes but in a easier to view format.

Display historical statistical resource usage from StackDriver. This will evaluate the TimeSeries data from StackDriver and show the latest value (the most current data point), minimum value, maximum value and the average or the mode in the requested duration per container. The average is displayed when cpu is requested. For memory the mode is displayed (mode is the most common occurring value in the set).
