C-0133 - Ensure that the API Server --audit-log-maxsize argument is set to 100 or as appropriate


Run Kubescape with host sensor (see here)

If you have set file size of 100 MB and the number of old log files to keep as 10, you would approximate have 1 GB of log data that you could potentially use for your analysis.
