WMI value

Kris · Post by **Kris** » Tue Oct 15, 2013 1:22 am

Hi,

I'm running the following query on one of our servers to get average latency:
select AvgDiskSecPerTransfer from Win32_PerfFormattedData_PerfDisk_PhysicalDisk where Name = '1 D:'

In windows perfmon it shows values somewhere between 0,000 and 0,025, which is to be expected.

However, in HM it just shows 0.

Am I doing something wrong here?

Thanks!

You are trying to compare results from two different sources:
WMI and Performance counters
You may setup "Performance counter" test (instead of WMI) and select same performance counter like in Windows perfmon.
E.g.

Code: Select all

\PhysicalDisk(1 D:)\Avg. Disk sec/Transfer

Why WMI and Perfmon givers different data?
Sorry we don't know. May be WMI returns only integer values.

Thanks!

Looks promising.
However, the performance counter only returns a 2-decimal value.
Is that all there is, or can I somehow get the 3-decimal value?

We can implement this option in next version

If you are using version 9.58, there is update at www.ks-soft.net/download/hm959.zip
Unzip files and replace hostmon.exe, rcc.exe and webservice.exe modules then add DigitsAfterDotStat=3 line into [Environ] section of hostmon.ini file and start HostMonitor.
