In a terminal type in, sudo yum install -y kernel-tools and hit enter. Type in your password if prompted. Now that we know it's installed, let's run it by typing in, sudo turbostat. Running turbostat with no arguments has a printout counter results every five seconds. Let this run for about 15 seconds and then press Control + C, so we can freeze the results. By default, it shows the processor core number, the Linux CPU logical processor number, the average clock speed over the course of the entire interval, the number of interrupt service by the CPU during the measurement interval, the number of System Management Interrupts or SMI, serviced by the CPU during the measurement interval, CPU%c1, CPU%c3, CPU%c6, and CPU%7. This is the percentage of the interval for which the CPU spent in each state. Pkg%pc2, is the…
