How do you calculate the % Processor Time on a Multi-Processor machine?
I have a Performance Counter Test that measures the % Processor Time for sqlservr. According to the Windows Performance Monitor the process is running about 140% (this is normal for some of our machines), but Host Monitor is only reporting 100%.
Is it possible that Host Monitor 3.40 is not calculating this correctly on a multi-processor machine? |

H'm, Performance Counter test does not calculate anything, it just inquires Windows and displays result...

What do you mean "log analyser show so bad display"? Does it display something wrong? Or you just don't want to have report with values over 100%?

I have sometimes results over 10000% on one server, you can imagine the result in the display with other values between 0 and 100%.
And yes, if value over 100% are wrong, they should not be displayed.

Could you try to use CPU Usage test instead of Performance Counter? CPU Usage test acesses to the same performance data but it does not use pdh.dll. May be it will show another results?

... just a short notice regarding this topic:
CPU monitoring by Performance Counter (mode: OneByOn) work on W2K and XP. You can even monitor single CPU- or 2,3 and 4 together!
On the other hand... the use of "CPU usage" directly does not show the "right" value in multiple CPU system (not here anyway).
Cheers,
Hans Mosegaard
