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"?

Answer 1

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.

Answer 2

You can also try the Get-Counter cmdlet:

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