 This experiment causes CPU resource consumption on specified application containers by starting one or more md5sum calculation process on the special file /dev/zero. It Can test the application's resilience to potential slowness/unavailability of some replicas due to high CPU load. Check <a href="https://docs.litmuschaos.io/docs/pod-cpu-hog/">pod cpu hog docs</a> for more info.
