========= Issue ========= 'sar -m CPU <interval> <count>' command does not return valid CPU FREQ values on powerkvm. I have the result pasted below captured on powerkvm vs x86 fedora system. On PowerKVM: [root@c158f2u07os ~]# sar -m CPU 1 5 Linux 4.4.4-1.el7_1.pkvm3_1_1.1200.0.ppc64le (c158f2u07os.pok.stglabs.ibm.com) 06/17/2016 _ppc64le_ (160 CPU) 06:30:28 AM CPU MHz 06:30:36 AM all 0.00 06:30:44 AM all 0.00 06:30:53 AM all 0.00 06:31:01 AM all 0.00 06:31:09 AM all 0.00 Average: all 0.00 >>Though I have given 1 sec interval, the real interval seems to be different as shown above. And FREQ MHz is shown 0. Same run on fedora x86 server: [srikanth@bssrikanth-tp ~]$ sar -m CPU 1 5 Linux 4.3.4-300.fc23.x86_64 04/15/2016 _x86_64_ (4 CPU) 12:08:47 PM CPU MHz 12:08:48 PM all 1793.18 12:08:49 PM all 2214.71 12:08:50 PM all 2170.32 12:08:51 PM all 1758.41 12:08:52 PM all 2444.70 Average: all 2076.26 This is the commit id: commit 93662b1dbe3eed926d67d418cd4996ede9686679 Author: Breno Leitao <[email protected]> Date: Mon Oct 31 09:23:59 2016 -0400 sar: Improve cpuinfo read for POWER architecture Currently CPU frequency is not being read properly on POWER archicture. It shows the frequency as: # sar -m CPU 1 5 ... 06:30:28 AM CPU MHz 06:30:36 AM all 0.00 This is caused because /proc/cpuinfo is differently between Intel and POWER. This patch simply fix the parsing function (read_cpuinfo).
