wmic cpu get loadpercentage returns 100% load for the 2nd CPU

Question

_{Friday, January 8, 2016 2:07 PM}

hi all,

has anyone a solution for this?

on certain systems the command line returns
C:\wmic cpu get loadpercentage
LoadPercentage
10
100

the load for the 2nd CPU is retuned always with a value of 100%, even if the system is idle

thanks in advance
andy

Hi Andy,

I tested on my Server 2012 R2 and Server 2008 R2, and the percentage seems to be correct, not always 100 on one CPU.

Are you using Server 2016 technical preview? If yes, update to the latest version and try again. If not, it is recommended to post in the dedicated forum for your OS version since this forum is for Server TP.

Besides, the output of the command is transient. If you want to observer and analyze the CPU usage, you could use performance monitor or resource monitor.   

Best Regards,

Leo

Hi Leo,

yes - it is on Server 2016 TP4, as well as on 2012R2 systems.

I opened this for 2016TP4 - for 2012 R2 I already contacted the HW vendor as well as Microsoft technical support.

But not all systems are affected - I currently have no idea whether the problem is bound to any of:

- a certain CPU type (seen XEON cores - I have no multicore AMD systems here)

• number of CPUs (seen it on 32 and 48 core systems - with hyperThreading enabled)
• a certain brand (seen it on HP servers, but not on a Fujitsu dual CPU system with 32 cores)

AnDi - I can confirm that I have duplicated this issue on TP4.  I know of no fix at this time.  Wait for the next release and test again.

Hi Tolli,

btw. also 2012R2 machines are affected, therefore waiting for the next TP makes no sense

can you  please drop the hw configuration of the machine,

make and name

cpu type and number of cpu's

thanks

andy

my machine:
HP ProLiant DL380 Gen9
2*Intel E5-2640 V3   with HT enabled => 2*8*2 = 32 cores

Hello Andreas,

What was the solution for this problem? i am having the same problem on two clusters now...

Jan,

there is no solution right now - the bug within WMIC is addressed with Microsoft, but not scheduled to be fixed.

in case it is an HP server, and the total core count is <= 64, go into the BIOS and switch
from 'Clustered' to 'Flat'

Hello Andreas,

Thank you for answering so fast! I am having the problem with Dell R730 servers.

We do have 2 18-core CPU's with Hyperthreading enabled > 64 Cores (72). I will check the BIOS Settings of the Dell servers for some similar settings.

Jan,

in this case you are lost - going back to 'Flat' mode means to have all cores in a single CPU-group.

This is possible, only, if the core count is <=64.
If you have more than 64 cores in the machine you have to use CPU-grouping, because the affinity mask interfaces are dealing with a longlong for machines without CPU grouping.

and the 'wmic cpu get loadpercentage' will show 100% load for every group if group# > 0
