The first stop -> stop0_lite stats and The second stop -> stop1_lite stats. cpupower monitor header prints the header list by getting the name of the idle stats. name (name description) snoo [T] -> snooze stop [T] -> stop0_lite stop [T] -> stop1_lite We can change the header to be more meaningful so user won't interpret it as 2 columns for stop. May be we need to change the code to print the header to use name description instead of name. . I will work on the patch and get it resolve. == Comment: #8 - PAVAMAN SUBRAMANIYAM <pavsu...@in.ibm.com> - 2017-06-30 03:42:01 == I have executed the command again with the fixed cpupower utility.
