The following detection script accomplishes the following.

  • Determines if virtual memory is automatically managed. The desired configuration according to the script is that the pagefile should be managed manually (true can be changed to false if you want to go the automagic route).
  • If the pagefile is not automatically managed, the script determines if the size of the page file is at least double the amount of visible physical memory.

I’m working on a remediation script, but for now I figure’d I would share the love.

# This script simply checks to see if Windows is handling the page file
# automagically. Then if no, it verifies to make sure that the swap file
# is set at or over twice the available memory. 

$system = get-wmiobject -Class win32_ComputerSystem

if ($system.AutomaticManagedPagefile -eq $true) {
    write-host FALSE
    } else {  

    $mem = get-wmiobject -Class win32_OperatingSystem | select-object TotalVisibleMemorySize,TotalVirtualMemorySize

    [int64]$vismem = $mem.TotalVisibleMemorySize
    [int64]$vrtmem = $mem.TotalVirtualMemorySize

    if ($vrtmem -ge ($vismem * 2)) {
        write-host TRUE
        } else {
        write-host FALSE
    }
}

A while back I wrote a MS SQL query to gather vitals for a PC Fleet in SCCM 2012. I have now updated it to include some more information like Make and information for the system partition (size/free/% used). I’ve also changed some of the columns to use the more Appealing Giga units of measurement instead of Mega.

This is so that if anyone ever asks what you have out there,  you can run a quick query and say “HERE YOU GO!” Enjoy! Written in Microsoft SQL Server Management Studio 2012.

NOTE: Search and replace {domain\} with your domain name or the query will fail, just FYI. Also, when you copy and paste, the lines will remain intact.

select distinct

CS.Manufacturer0 [Make],
CS.Model0 [Model],
CS.Name0 [Hostname], 
replace(CS.UserName0,'{domain\}','') [Primary User],
OS.Caption0 [OS],
OS.InstallDate0 [Image Date],
cast(CPU.MaxClockSpeed0/1000.00 as decimal(10,2)) [Speed (MHz)],
CPU.Name0 [CPU],
CPU.NumberOfCores0 [Cores],
CPU.IsHyperthreadCapable0 [Hyperthread],
DSK.Caption0 [HDD],
cast(DSK.Size0/1000.00 as decimal(10,2)) [HDD Capacity (GB)],
cast(LDSK.Size0/1000.00 as decimal(10,2)) [C Size (GB)],
cast(LDSK.FreeSpace0/1000.00 as decimal(10,2)) [C Free (GB)],
cast((LDSK.FreeSpace0 * 100.00)/(LDSK.Size0 * 1.00) as decimal(10,2)) [C %Free],
cast(OS.TotalVirtualMemorySize0/1000.000 as decimal(10,3)) [Virtual Memory (GB)],

Here’s a nifty little query that will return the physical memory configuration of each computer registered in SCCM 2012. I’m excluding the System ROM (where layeth the BIOS) because we don’t really care about that here. We want the RAM! Written in SQL Server Management Studio 2012.

select 

v_GS_PHYSICAL_MEMORY.DeviceLocator0 as [Slot],
v_GS_PHYSICAL_MEMORY.Capacity0 as [Size],
v_GS_PHYSICAL_MEMORY.Manufacturer0 as [Manufacturer],
v_GS_PHYSICAL_MEMORY.PartNumber0 as [Part Number],
v_GS_Computer_System.Model0 as [Model],
v_GS_Computer_System.Name0 as [Hostname],
v_GS_Computer_System.UserName0 as [Username]

from v_GS_PHYSICAL_MEMORY

left join v_GS_COMPUTER_SYSTEM on v_GS_PHYSICAL_MEMORY.ResourceID=v_GS_COMPUTER_SYSTEM.ResourceID

/* We don't care about the system rom. */
where v_GS_PHYSICAL_MEMORY.DeviceLocator0 not like 'SYSTEM ROM'

/* Sort by hostname. */
order by v_GS_Computer_System.Name0
