Need help with Azure VM reboot which checks users logged in.

[newtotechcom-J]

Hi guys,

I have been looking for methods to restart AVD using runbooks and automation.
I have info on how to restart VMS, but I want to restart the VMs such that it checks if any users are logged in and if the users are logged in. It won't restart.

This is the script that I found to restart from linkedin: https://www.linkedin.com/pulse/scheduling-reboot-azure-virtual-machines-using-automation-rabea/:

workflow demo
{
    InlineScript
    {
        Connect-AzAccount -Identity
Restart-AzVM -ResourceGroupName "Resource Group name" -Name "VM1 name"
Restart-AzVM -ResourceGroupName "Resource Group name" -Name "VM2 name"
Restart-AzVM -ResourceGroupName "Resource Group name" -Name "VM3 name"
    }
}

Thanks, I'll try it out.

Do they have explanations. I prefer that where I can take a sample exam and then read the explanation. Are the exams updated frequently?

I created this script and tested it in Runbook. But getting an error.

The script:
workflow Restart-AVDVMsIfNoUser {
param (
[Parameter(Mandatory = $true)]
[string] $ResourceGroupName,

[Parameter(Mandatory = $true)]
[string[]] $VMNames,

[Parameter(Mandatory = $true)]
[string] $HostPoolName
)

InlineScript {
# Authenticate to Azure
Connect-AzAccount -Identity

# Loop through each VM name
foreach ($VMName in $using:VMNames) {
# Retrieve active user sessions on the VM
$userSessions = Get-AzWvdUserSession -ResourceGroupName $using:ResourceGroupName -HostPoolName $using:HostPoolName -Name $VMName

# Check if there are any active user sessions
if ($userSessions.Count -eq 0) {
# No users are logged in, restart the VM
Write-Output "Restarting VM: $VMName as no users are logged in"
Restart-AzVM -ResourceGroupName $using:ResourceGroupName -Name $VMName
}
else {
# Users are logged in, do not restart the VM
Write-Output "Not restarting VM: $VMName as users are logged in"
}
}
}
}

# Example usage of the workflow
Restart-AVDVMsIfNoUser -ResourceGroupName "YourResourceGroupName" -VMNames @("VM1Name", "VM2Name", "VM3Name") -HostPoolName "YourHostPoolName"
