.SH ADD PERF COUNTER EXAMPLE

Here we limit turbostat to showing just the CPU number for cpu0 - cpu3.

We add a counter showing time spent in C1 core cstate,

labeling it with the column header, "pCPU%c1", and display it only once,

after the conclusion of 0.1 second sleep.

We also show CPU%c1 built-in counter that should show similar values.

.nf

sudo ./turbostat --quiet --cpu 0-3 --show CPU,CPU%c1 --add perf/cstate_core/c1-residency,cpu,delta,percent,pCPU%c1 sleep .1

0.102448 sec
