Quick Usage

To use PowerJoular, just run the command powerjoular. On PC/servers, PowerJoular uses Intel's RAPL through the Linux powercap sysfs, and therefore requires root/sudo access on the latest Linux kernels (5.10 and newer): sudo powerjoular.

By default, the software will show the power consumption of the CPU and its utilization. The difference (increase or decrease) of power consumption from last metric will also be shown.

To monitor a specific application, just run PowerJoular with the -a appName parameter. PowerJoular is a powerful tool with many functionalities that can be accessed using specific parameters. Check the Command Line Options page for the detailed list.
