            Bug ID: 50728
           Summary: % CPU Utilization monitor/gauge/indicator not
                    functioning in VARA.exe (ham radio software)
           Product: Wine
           Version: 6.2
          Hardware: x86
                OS: Linux

Terminal output from running VARA (seeing CPU monitor bug) and then closing it.

When I run a ham radio program, called VARA, through Wine I'm noticing that the
program doesn't properly display CPU usage in its "CPU Gauge". It instead just
says "%CPU not available". (See this thread for an image:
https://groups.io/g/VARA-MODEM/message/1311)  I'm assuming it might be an
unimplemented function or missing library in Wine, but I don't know how to
track down what is missing.

This is with a fresh installation of wine-staging 6.2 and a fresh wineprefix. 
The bug doesn't occur when VARA is run on a Windows computer.  I've attached
terminal output of the program running (and then being closed).  I'm wondering
if this may be similar to bug 26785, though that one was fixed in 2016.

I'm wondering if the bug might be related to one of these warnings:
0024:fixme:advapi:RegisterEventSourceW ((null),L"PDH"): stub

error 2

I'm very new to debugging though and assume that this will take more than just
dropping in dll's and doing winecfg dll overrides (especially if ntdll is at
fault here). Does anybody have any insight into Wine's ability to query system
resources - or some ideas for commands I could try to track this bug down and
report it to the Wine team for possible request for implementation? There's a
whole community of hams who would love to have this program 100% operational
(even though this is a minor bug).



To reproduce this behavior, you can install VARA with these commands:

#### Configure our wineprefix
winetricks -q corefonts dotnet35sp1 vb6run win7 sound=alsa vcrun2015 pdh # run
pdh here just for the winecfg dll override

# Install an older pdh.dll (the pdh.dll from "winetricks pdh" is too new for
VARA)
sudo apt-get install zip -y
cd ~/Downloads && mkdir pdhNT40 && cd pdhNT40
wget
http://download.microsoft.com/download/winntsrv40/update/5.0.2195.2668/nt4/en-us/nt4pdhdll.exe
unzip -o nt4pdhdll.exe
cp pdh.dll ~/.wine/drive_c/windows/system32


####  Download/extract/install VARA HF (or newer)
[https://rosmodem.wordpress.com/]
sudo apt-get install p7zip-full -y
sudo apt-get install megatools -y

cd ~/Downloads
VARALINK=$(curl -s https://rosmodem.wordpress.com/ | grep -oP '(?<=<a
href=").*?(?=" target="_blank" rel="noopener noreferrer">VARA HF v)') # Find
the mega.nz link from the rosmodem website no matter its version, then store it
as a variable
megadl ${VARALINK}
7z x VARA*.zip -o"VARAInstaller" -y
wine ~/Downloads/VARAInstaller/VARA\ setup*.exe /SILENT


####  Configure VARA
# In winecfg, go to the Audio tab to set up your default in/out soundcards
wine winecfg

# In VARA, set up your soundcard input and output (go to Settings ...
Soundcard)
wine ~/.wine/drive_c/VARA/VARA.exe
