The allocatable diff tool iterates through your list of currently deployed nodes and compares them to Karpenter's expectation of the capacity and allocatable on these nodes. It outputs a CSV file that can be used for further analysis to compare the values like expected capacity and allocatable capacity to determine values like vmMemoryOverheadPercent in the AWS cloudprovider.
