We're currently using wmic to get the CPU and memory usage for the "Servers" card on Windows (this was introduced in #165)

@wilianmaique or @kohenkatz are you aware of any alternative ways of getting this information without wmic?

Note that it's possible to customize how CPU and memory usage are determined with the following:

\Laravel\Pulse\Recorders\Servers::detectCpuUsing(fn () => /* CPU percentage as an integer */);

\Laravel\Pulse\Recorders\Servers::detectMemoryUsing(fn () => [
    'total' => /* Total memory in megabytes as an integer */,
    'used' => /* Used memory in megabytes as an integer */
]);

'used' => / Used memory in megabytes as an integer */
]);

I used COM and it worked correctly:

$wmi = new \COM("WinMgmts://");
    $cpus = $wmi->ExecQuery("SELECT LoadPercentage FROM Win32_Processor");

    [$totalCpuLoad, $cpuCount] = 0;

    foreach ($cpus as $cpu) {
      $totalCpuLoad += $cpu->LoadPercentage;
      $cpuCount++;
    }

    $averageCpuLoad = $cpuCount > 0 ? $totalCpuLoad / $cpuCount : 0;

    $memory = $wmi->ExecQuery("SELECT TotalVisibleMemorySize, FreePhysicalMemory FROM Win32_OperatingSystem");
    $mem = $memory->ItemIndex(0);

    $totalMemory = $mem->TotalVisibleMemorySize * 1024;
    $freeMemory = $mem->FreePhysicalMemory * 1024;
    $usedMemory = $totalMemory - $freeMemory;
    $usedPercentage = ($usedMemory / $totalMemory) * 100;

    echo '<pre>';
    print_r([
      'CPU Load (%)' => $averageCpuLoad,
      'Total Memory' => Number::fileSize($totalMemory, precision: 2),
      'Free Memory' => Number::fileSize($freeMemory, precision: 2),
      'Used Memory' => Number::fileSize($usedMemory, precision: 2),
      'Used Memory Percentage (%)' => Number::percentage($usedPercentage, precision: 2)
    ]);
    echo '</pre>';

out:

Array
(
    [CPU Load (%)] => 14
    [Total Memory] => 31.87 GB
    [Free Memory] => 16.19 GB
    [Used Memory] => 15.68 GB
    [Used Memory Percentage (%)] => 49.19%
)

note, you need to enable: extension=com_dotnet in php.ini (this extension is already included)

[kohenkatz]

wmic isn't actually removed from Windows 11, just the executable is disabled by default. You can re-enable it like this (as admin):

DISM /Online /Add-Capability /CapabilityName:WMIC~~~~

That said, switching to the com_dotnet extension is probably a better way forward. I don't have time to do a PR myself at the moment, but it looks like a fairly simple change.
