RE: Win32::AdminMisc::GetMemoryInfo reporting unrealistic data

Title: RE: Win32::AdminMisc::GetMemoryInfo reporting unrealistic data

The AdminMisc function probably uses the GlobalMemoryStatus() Win32 API call,

which stores memory values as bytes in a 32-bit integer.  Unfortunately, any values

4 GB or greater will overflow this value.  The GlobalMemoryStatusEx() function

should be used instead, but I'm not aware of any perl modules that use it.  For my

own use, I wrote a small exe in C which reports the size correctly using

GlobalMemoryStatusEx() and I just system() that from perl.

 

I don't think the registry routine below works either, on my machine it reports 16 MB

when I actually have 512.

You could use Win32::TieRegistry, for testing...

use Win32::TieRegistry( Delimiter=>"\\", ArrayValues=>0 );

$machine="\\\\COMPUTERNAMEGOESHERE";   # leave all 4 slashes, please.

$regstr="$machine\\HKEY_LOCAL_MACHINE\\HARDWARE\\RESOURCEMAP\\System Resources\\Physical Memory\\";
$regobj=$Registry->{$regstr};
$memstr=$regobj->Win32::TieRegistry::GetValue("\.Translated");
$last=unpack(C,substr($memstr,(length($memstr)-1),1));
$memtot=(16*($last+1));
print "Mem on $machin = $memtot Megs\n";

Try that one on for size and see what it reports...

Subject: Win32::AdminMisc::GetMemoryInfo reporting unrealistic data

Hi all,

   I've got a Dell server on hands and a Perl app which reports on the
status of certain servers on my network.

the following is the perl script:

use Win32::AdminMisc;

%Mem = Win32::AdminMisc::GetMemoryInfo();

%Processor = Win32::AdminMisc::GetProcessorInfo();

foreach (sort keys %Mem) {
   print "$_: $Mem{$_}\n";
}
foreach (sort keys %Processor) {
   print "$_: $Processor{$_}\n";
}

And this is what it reports:

Load: 80
PageAvail: 1701429248
PageTotal: -1
RAMAvail: 1603432448
RAMTotal: 2147483647
VirtAvail: 2115244032
VirtTotal: 2147352576
MMX: 1
OEMID: 0
PageSize: 4096
ProcessorLevel: 15
ProcessorNum: 8
ProcessorRevision: 257
ProcessorSpeed: 1932
ProcessorType: 586
Win32ProcessorSpeed: 1393

Uh....  Well...  Most of the data reported is correct, except for RAMTotal.
Its being reported as a 2GB server, while in fact it is a server with 8GB
of RAM.

This might have been reported before. So I hope someone might help me out
on this.
Also, the Perl -v reports as 5.6.1, build 630.

Any info would be greatly appreciated..

Thanks,

/LG
