i like vCheck to daily report my virtual environment status. But a lot of our guest systems are not in my responsibility, so the VM Tools are not uptodate or aren’t installed.

i wroted this plugin for vCheck:

$Title = "VMs by VM Tools status"
$Header = "VMs by VM Tools status : $($VMToolsVersions.count)"
$Comments = "The following Operating Systems are in use in this vCenter."
$Display = "Table"
$Author = "Josh Burkard"
$Version = 1.0

# Start of Settings
# —- VM Guest OS Pivot Table —-

$VMTools = get-vm | % { get-view $_.ID } | select Name, @{ Name="hostName"; Expression={$_.guest.hostName}}, @{ Name="ToolsStatus"; Expression={$_.guest.toolsstatus}}, @{ Name="ToolsVersion"; Expression={$_.config.tools.toolsVersion}} | sort-object ToolsVersion

$VMToolsVersions = $VMTools | Where { $_.ToolsStatus -ne "toolsOk" } | sort ToolsVersion -desc

If (($VMToolsVersions | Measure-Object).count -gt 0 -or $ShowAllHeaders) 
{
	$MyReport += Get-CustomHeader "VMs by VM Tools status : $($VMToolsVersions.count)" "The following VM Tools Status are not OK or old."
	$MyReport += Get-HTMLTable $VMToolsVersions
	$MyReport += Get-CustomHeaderClose
}
