Powershell makes it easy to get information from remote servers.
Below is the query to "calculate RAM using powershell" of all the remote servers you are connected with-
Step1- Create the list of all the servers in a notepad with name "serverlist.txt". I have saved this file on location "D:\Powershell" you can change it with your own location.
Step2- Execute below script-
$servers = Get-Content "D:\PSScripts\bstServerlist.txt"
$SystemInfo = "D:\PSScripts\bstSystemInfo.txt"
$ErrorInfo = "D:\PSScripts\bstErrorInfo.txt"
FOREACH($server in $servers)
$System = gwmi -computer $server -class win32_computersystem -ErrorVariable MyError -ErrorAction Silentlycontinue
$Ram = [math]::round($System.Totalphysicalmemory/(1024*1024*1024),2)
write-output "$server - $Ram " | out-file -filepath $SystemInfo -append
You can also save the script in a notepad and save it with extension ".ps1". When you will execute the file RAM information for all the servers in the server list will store in the RAMInformation file.
