How to get free physical memory of remote computer using PowerShell

Question

I have this:

(Get-WMIObject Win32_logicaldisk -computername computer).TotalPhysicalMemory

to get size of physical memory installed on remote computer. How do I get the FREE memory of that computer?

I've tried

(Get-WMIObject Win32_logicaldisk -computername computer).FreePhysicalMemory

and some other variants, but with no effect. Is there some list of possible "filters"?

Whenever you want to see all of the properties of an object, pipe it to Format-List *.

Get-WmiObject Win32_LogicalDisk | format-list *
Get-WmiObject Win32_OperatingSystem | fl *

Or if you are looking for a particular propery, you can use wildcard search

Get-WmiObject Win32_OperatingSystem | fl *free*

As Aquinas says, you want the Win32_OperatingSystem class, FreePhysicalMemory property. Win32_LogicalDisk tracks hard disks, not RAM.

If he actually means diskspace, the properties would be `Size` and `FreeSpace`. – Ansgar Wiechers Sep 03 '12 at 17:55

You can also try the Get-Counter cmdlet:

(Get-Counter -Counter "\Memory\Available MBytes" -ComputerName computer).CounterSamples[0].CookedValue

You want Win32_OperatingSystem not Win32_logicaldisk I believe.

So putting together the other answers:

get-ciminstance Win32_OperatingSystem | % FreePhysicalMemory

Remotely:

invoke-command computer { get-ciminstance Win32_OperatingSystem | % FreePhysicalMemory }

I believe this should really be `Get-CimInstance Win32_OperatingSystem`. `Get-WmiObject` was deprecated since PowerShell 3.x and removed since PowerShell 6.x. – TheFreeman193 Mar 01 '21 at 22:52

Free memory of the local machine (use -computername foo for a remote one):

(Get-WMIObject Win32_OperatingSystem).FreePhysicalMemory  # in KB

19793740

(Get-WMIObject Win32_OperatingSystem).FreePhysicalMemory / 1MB  # in GB

18.8592491149902

Might seem weird to divide by 1MB to get GB, but the original number is just given in KB. The result is actually no different from writing * 1KB / 1GB (which you can also use).
