Win32::Process::Info::WMI - Provide process information via WMI.
This package fetches process information on a given Windows machine, using Microsoft's Windows Management Implementation.
use Win32::Process::Info $pi = Win32::Process::Info->new (undef, 'WMI'); $pi->Set (elapsed_as_seconds => 0); # In clunks, not seconds. @pids = $pi->ListPids (); # Get all known PIDs @info = $pi->GetProcInfo (); # Get the max
This package is not intended to be used independently; instead, it is a subclass of Win32::Process::Info, and should only be called via that package.
This package implements the WMI-specific methods of Win32::Process::Info.
This package returns Windows process IDs, even under Cygwin.
The following methods should be considered public:
- @info = $pi->GetProcInfo ();
This method returns a list of anonymous hashes, each containing information on one process. If no arguments are passed, the list represents all processes in the system. You can pass a list of process IDs, and get out a list of the attributes of all such processes that actually exist. If you call this method in scalar context, you get a reference to the list.
What keys are available depend both on the variant in use and the setting of b<use_wmi_names>. Assuming use_wmi_names is TRUE, you can hope to get at least the following keys for a "normal" process (i.e. not the idle process, which is PID 0, nor the system, which is PID 8) to which you have access:
CSCreationClassName CSName (= machine name) Caption (seems to generally equal Name) CreationClassName CreationDate Description (seems to equal Caption) ExecutablePath KernelModeTime MaximumWorkingSetSize MinimumWorkingSetSize Name OSCreationClassName OSName OtherOperationCount OtherTransferCount Owner (*) OwnerSid (*) PageFaults ParentProcessId PeakWorkingSetSize ProcessId ReadOperationCount ReadTransferCount UserModeTime WindowsVersion WorkingSetSize WriteOperationCount WriteTransferCount
You may find other keys available as well.
* - Keys marked with an asterisk are computed, and may not always be present.
- @pids = $pi->ListPids ();
This method lists all known process IDs in the system. If called in scalar context, it returns a reference to the list of PIDs. If you pass in a list of pids, the return will be the intersection of the argument list and the actual PIDs in the system.
It should be obvious that this library must run under some flavor of Windows.
This library uses the following libraries:
Carp Time::Local Win32::OLE use Win32::OLE::Const; use Win32::OLE::Variant;
As of ActivePerl 630, none of the variant libraries use any libraries that are not included with ActivePerl. Your mileage may vary.
This module would not exist without the following people:
Jenda Krynicky, whose "How2 create a PPM distribution" (http://jenda.krynicky.cz/perl/PPM.html) gave me a leg up on both PPM and tar distributions.
