Computing the Private Working Memory of a Set from WMI Class Methods
I am using the following perl program which uses the WMI Win32_Process class to determine the memory usage of a process
use strict;
use warnings;
use Win32::OLE qw/in/;
sub memory_usage()
{
my $objWMI = Win32::OLE->GetObject('winmgmts:\\\\.\\root\\cimv2');
my $processes = $objWMI->ExecQuery("select * from Win32_Process where Name=\'notepad.exe\'");
my $memory = 0;
foreach my $proc (in($processes))
{
$memory = $memory + $proc->{WorkingSetSize};
}
return $memory;
}
print 'Memory usage: ', memory_usage(), "\n";
The WMI Win32_Process class and its properties are listed on MSDN here
The problem is that it calculates the set working memory and I want to calculate the set private working memory for which the property is not defined in the linked page
Is there a way that I can compute the private working memory of a set from this class?

Change Win32_Process
to Win32_PerfRawData_PerfProc_Process
and property WorkingSetSize
to WorkingSetPrivate
. This will give you a private working set.
