Powershell One Liners: Get current cpu utilization on all your Servers

There are couple pre-requisites to get the CPU usage on servers.

• You need to have the administrative rights on the servers
• PowerShell must be launched in elevated privileges mode

# Assuming you have list of servers in servers.txt, each server name in its own line

$ComputerNames = get-content servers.txt

# Method 1 - Using the Get-Counter cmdlet

# Notice that here you can also easily add the interval and max sample sizes, with the WMI  method shown next, you cannot

Get-Counter -Counter "\Processor(_Total)\% Processor Time" `

            -SampleInterval 1 `

            -MaxSamples 2 `

            -ComputerName $ComputerNames | 

          

            Export-Counter -path PercentageProcessorTime.csv `

                           -fileformat csv -force

# Method 2 - Using WMI Object

Get-WmiObject -Query "Select * from Win32_PerfFormattedData_PerfOS_Processor where name = '_Total'" `

              -ComputerName $ComputerNames | 

              sort PercentProcessorTime -descending | 

              ft -Property PSComputerName, name, PercentProcessorTime -autosize
