Here is a script on VMware via Powershell. As long as you have installed the PowerCLI module, you can run this via the standard Powershell. I have taken the script and created a PS1 file to run through the list and email it to you. This will help in the cases whereby an application or service is not cluster aware and a migration takes place. Or if a Hosts reboots and the VM comes up but for some reason, it is not able to auto-connect. Now all your resources may not have access to VCenter or may not know how to check. This email will help to notify the team.

$smtpsettings = @{
To = “user@domain.co.za”
From = “support@domain.co.za”
Subject = “VMware PoweredOn Systems with Disconnected NICs”
SmtpServer = “<smtp server”
}
$objs = @()
$emailBody = “<table border=’1’><tr><th>Parent</th><th>NetworkName</th><th>ConnectionState</th><th>”
$csvs = Get-VM | Where-Object {$_.Powerstate -eq “PoweredOn”} | Get-NetworkAdapter | Where-Object {$_.
ConnectionState -match “NotConnected”} | select Parent,NetworkName,ConnectionState
foreach ( $csv in $csvs )
{
$emailBody = $emailBody + “<tr><td>” + $csv.Parent + “</td><td>” + $csv.NetworkName + “</td><td>” + $csv.ConnectionState + “</td></tr>”
}
$emailBody = $emailBody + “</table>”
Send-MailMessage @smtpsettings -Body $emailBody -BodyAsHtml -Encoding ([System.Text.Encoding]::UTF8)
Add the above on to a text document. Then save it as a .ps1 file. When you run it, it will run in Powershell and email you. You can run this manually or create a task scheduler to run.
