*How to get (remote) performance metrics, like CPU, memory, disk and Networking
*get-counter
*get performance information from remote system
*get performance counter from remote system
*get CPU usage
*get memory usage
*get disk usage
*get network usage
*powershell
*learn powershell
*automation

Code :

#man Get-Counter

#Get-Counter -ListSet * | ogv
#Get-Counter -ListSet * | where countersetname -eq processor | select -ExpandProperty counter
$servername = "hv02"
#$cred = Get-Credential

while($true){
Invoke-Command -ComputerName $servername -ScriptBlock {
$cpu = Get-Counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 1 -MaxSamples 1
$mem = Get-Counter -Counter "\Memory\Committed Bytes" -SampleInterval 1 -MaxSamples 1
$nic = Get-Counter -Counter "\Network Interface(*)\Bytes Total/sec" -SampleInterval 1 -MaxSamples 1
$disk = Get-Counter -Counter "\PhysicalDisk(*)\Disk Bytes/sec" -SampleInterval 1 -MaxSamples 1
$prop = @{
#servername = $servername
cpu = $cpu.CounterSamples.CookedValue
mem = $mem.CounterSamples.CookedValue
nic = $nic.CounterSamples.CookedValue
disk = $disk.CounterSamples.CookedValue
}
New-Object psobject -Property $prop
} -Credential $cred

Start-Sleep -Seconds 2
}
