Here is a quick line of code you can throw in to your existing scripts if you want to do some validation based on the type of vcenter.
As more companies are moving to the vCenter appliance, MS Windows issues go away.   Until that time, it’s good to alert on disk space and CPU usage for the Windows vCenter.

The quick one-liner to check the vCenter OS:
if(($global:DefaultVIServer | %{$_.extensiondata.content.about.ostype}) -match “win”){ $windows}else{$Linux}

Here is a Windows vCenter “CPU and Disk space” check script:

$vcenter = “vcenter.pcli.me”
$localWindowsAccountUser = “user001″
$localWindowsAccountPass = “test”
## if you want to use a domain account then edit the “$pcstring” var below

Connect-VIServer $vcenter

if(($global:DefaultVIServer | %{$_.extensiondata.content.about.ostype}) -match “win”){
$report=@()
$pcstring = $vcenter+”\”+$localWindowsAccountUser
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $pcstring,(ConvertTo-SecureString -String $localWindowsAccountPass -AsPlainText -Force)
$temp = get-WmiObject win32_logicaldisk -Computername $vcenter -credential $Credential
foreach($b in ($temp | where {$_.drivetype -eq “3″})){
$reportrow = “” | select VMname, DriveLetter, VolumeName,CapacityGB, FreespaceGB,percentFree
$reportrow.vmname = $vcenter
$reportrow.driveletter = $b.DeviceID
$reportrow.VolumeName = $b.VolumeName
$reportrow.capacityGB = “{0:N3}” -f ($b.Size / 1073741824)
$reportrow.freespaceGB = “{0:N3}” -f ($b.FreeSpace / 1073741824)
$reportrow.percentfree = [System.Math]::floor(($b.FreeSpace / $b.Size)*100)
$report += $reportrow
}
$cpucheck = get-WmiObject win32_processor  -Computername $vcenter -credential $Credential | Measure-Object -property LoadPercentage -Average | Select Average
if(([int]($cpucheck.average)) -ge 90){
$smtpServer = “smtp.pcli.me”
$msg = new-object Net.Mail.MailMessage
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$msg.From = “Script@pcli.me”
$msg.To.Add(“Team@pcli.me”)
$sub = “vCenter HIGH CPU usage found for “+$vcenter
$msg.subject = $sub
$msg.Body = “”
$smtp.Send($msg)
}}
Disconnect-VIServer -Server $global:DefaultVIServers -Force -confirm:$False
