PVS Info to Environment Variables / Event Log Refreshed

In my old post I presented a Powershell startup script to grab some info from the PVS image and pump it into the eventlogs and environment variables for consumption.   I refreshed this for the VHDX disks and "Cache in Ram with overflow" cache type.  

Start by creating the event log from an elevated poweshell session by issuing the command:

New-EventLog -LogName Application -Source "Xenapp_Custom"

I run the script below in the local startup scripts on the PVS images.

------------PVS_Personality.ps1------------------------
$disk="ID not found"
$file="c:\personality.ini"

IF(Test-Path $File){
  $data=get-content $file
  Foreach ($line in $data) {
    if ($line.Contains("DiskName")){$iname=$line.replace("$","").replace("DiskName=","").replace(".vhdx","").replace(".vhd","")}
    if ($line.Contains("WriteCacheType")){$wc=$line.replace("$","").replace("WriteCacheType=","")}
    }


  switch ($wc)
  { 
  "0" {$wc1="PV"}
  "4" {$wc1="CD"}
  "6" {$wc1="CR"}
  "9" {$wc1="CRO"}
  "1" {$wc1="Server";Write-EventLog -LogName Application -Source "XenApp_Custom" -EntryType Error -EventID 911 -Message "PVS ALERT. VDisk is set to Cache on server.  Immediate action is required to prevent an outage if this is a PROD image. Image: $iname"}
default {$wc1="OTHER";Write-EventLog -LogName Application -Source "XenApp_Custom" -EntryType Warning -EventID 911 -Message "PVS ALERT. Nonstandard VDisk configuration has been detected. Image: $iname"}
}
  $disk=$iname+"_"+$wc1
  } 


ELSE 
  {$disk=$env:computername + "_Local"}

[Environment]::SetEnvironmentVariable("PVS_Disk",$disk,"Machine")
