PS Core | Disconnect VI Session

Steps to Disconnect VI Session with PowerCLI on PowerShell Core

1. Login to vCenter with valid Username & Password

#PowerCLI - PowerShell Core on Windows 10
#First Time Only
Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
Set-PowerCLIConfiguration -ParticipateInCeip $true

#Import VMware Module
Import-Module VMware.VimAutomation.Core

#Connect to vCenter
$VC = "10.3.3.15"
$Username = "[email protected]"
$PAssword = "P@ssw0rd01"

Connect-VIServer -Server $VC -User $Username -Password $PAssword -WarningAction SilentlyContinue

2. List the Active Session

#List PowerCLI Session
$svcRef = new-object VMware.Vim.ManagedObjectReference
$svcRef.Type = "ServiceInstance"
$svcRef.Value = "ServiceInstance"
$ServiceInstance = get-view $svcRef
$SessionManager = get-view $ServiceInstance.Content.SessionManager
foreach ($Session in $SessionManager.SessionList) {
    #Filter the VI Session for VPXd, and only list with valid users' login
    if ($Session.UserName -notlike "*vpxd*") {
        #if (($sess.LastActiveTime).addminutes(60) -lt (Get-Date)){
        Write-Output "$($Session.IpAddress) $($Session.UserName) $($Session.LoginTime) $($Session.UserAgent) $($Session.Key) "
    }
}

Output of the above script with Username, IPAdress, LoginTime, UserAgent and Key show

3. Search the session based on IP, Username, LoginTime, UserAgent or Key and kill it

#Search the sessions that are idle for 12 Hours and kill it
$IdleTime = "12"
$SessionManager.SessionList | ? {$_.LastActiveTime -lt (Get-Date).AddHours(-$IdleTime)} |% {$SessionManager.TerminateSession($_.Key)}

#Search the session that are from IP Address of 10.3.3.12 and kill them
$SessionManager.SessionList | ? {$_.IpAddress -like "10.3.3.12"} |% {$SessionManager.TerminateSession($_.Key)}

4. You can also Terminate the Active Session via vCenter Web GUI
