Using turbostat to Review Detailed CPU Statistics

Use turbostat to review x86_64 processor frequency, power, and idle state statistics.

Before running the turbostat command, install the kernel-tools package. This prerequisite is the same regardless of whether Oracle Linux 8 runs on the Unbreakable Enterprise Kernel (UEK) or the Red Hat Compatible Kernel (RHCK).

To monitor CPU statistics and update the output every five seconds, run the following command:

turbostat

To remove hardware information at the start of the command output, add the --quiet option to the turbostat command: 

turbostat --quiet

To change the time output interval, use the -i option. For example, to see new turbostat output every ten seconds, run the following command: 

turbostat -i 10

For more information, see the turbostat(8) manual page.
