Pool Host "Needs Attention"

Great tip Moses!  I'll mention this one to our support team as well!

Hi Moses,

This "Needs Assistance" status indicates that the VM failed one of the following non-fatal health checks: the Geneva Monitoring Agent health check, the Azure Instance Metadata Service (IMDS) health check, or the URL health check.

It sounds like it was related to the Geneva agent in your case, but the following Microsoft guidance can be referenced for troubleshooting hosts in this status: Error: Session hosts are stuck in the Needs Assistance state

Furthermore, if you navigate to the VM status in the Azure Portal (Azure Portal > Azure Virtual Desktop > Host Pools > Session Hosts > yoursessionhostname) you can check on all of the session host Health checks and see which checks are successful/failing. This is useful for if the hosts report an "Unavailable" status as well.:

Very cool find, Moses Hull!

If someone was adventurous enough (a.k.a. had more PowerShell skills than me 😅), they could write a Scripted Action (PowerShell Script) to scan the directory, get the file name, run the installer and then pause for 3-5 minutes. From there, the scripted action could be added to the Run scripted actions after restart attempts of the Auto-Heal Broken Hosts section of the Auto-Scale Settings. 

$path = "C:\program files\Microsoft RDInfra\Microsoft.RDInfra.Geneva.Installer*"
$msifile = Get-childitem $path | select -ExpandProperty Name
$program = '"C:\program files\Microsoft RDInfra\'+ $msifile + '"'
start-process -WAIT -FilePath $program  -ArgumentList "/qn"

So speedy!

Found a bug in the script. Give me a minute to correct it.

corrected.
