There was a requirement to get status and cpu / memory usage of some specific windows servers. I used below script:
This is an example of Windows Search Service.
$cpu = Get-WmiObject win32_processor
$search = get-service "WSearch"
if ($search.Status -eq 'Running')
{
$searchmem = Get-WmiObject Win32_Service -Filter "Name = 'WSearch'"
$searchid = $searchmem.ProcessID
$searchcpu1 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
Start-Sleep -Seconds 1
$searchcpu2 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
$searchp2p1 = $searchcpu2.PercentProcessorTime - $searchcpu1.PercentProcessorTime
$searcht2t1 = $searchcpu2.Timestamp_Sys100NS - $searchcpu1.Timestamp_Sys100NS
$searchcpu = [Math]::Round(($searchp2p1 / $searcht2t1 * 100) /$cpu.NumberOfLogicalProcessors, 1)
$searchmem = [Math]::Round($searchcpu1.WorkingSetPrivate / 1mb,1)
Write-Host 'Service is' $search.Status', Memory consumed: '$searchmem' MB, CPU Usage: '$searchcpu' %'
}
else
{
Write-Host Service is $search.Status -BackgroundColor Red
}
