Elevated Powershell using Zabbix Agent

[frater]

This is my first powershell script I wrote.
I much prefer bash, but with the help of Google I was able to finish this... ;-)
After finding out that one of the servers we're monitoring had a harddisk that wasn't being back-uped I wanted a way to monitor this.

The powershell script is working, but it needs to be run as administrator.
I haven't even tried to run it from Zabbix as I know the first command would fail.

I have this now in zabbix_agentd.conf

UserParameter=reg.info[*],%systemroot%\system32\cscript.exe /nologo /T:10 "C:\Program Files (x86)\Zabbix Agent\reginfo.vbs" "$1" "$2" $3 "$4"
UserParameter=net.ping[*], ping -n 1 -w 1 "$1" 2>null | find  /i "TTL=" /c
UserParameter=vfs.files.exists[*], dir "$1" 2>null | find /c "bytes "
UserParameter=vfs.files.countsuffix[*], dir "$2\*.$1" 2>null | find /c /i ".$1"
UserParameter=system.notbackuped,powershell -File "C:\Program Files (x86)\Zabbix Agent\NotBackuped.ps1"

It's the last line...
What is needed to run that file using administrator privileges?
Hopefully this can be done with a minimal impact on general security.

Here's the script for those interested:

add-pssnapin windows.serverbackup 

# Get Harddisks with a driveletter
$harddisks = GET-WMIOBJECT -query "SELECT * from win32_logicaldisk where Size > 49999999999 and DriveType = 3"  | Where-Object {$_.VolumeName -NotMatch 'Back'} | ForEach-Object {$_.DeviceID}

# Extract only the driveletters
# $harddisks = select-string -pattern "DeviceID" WMI_LOGICALDISKS | foreach { $_.ToString().split(" ")[6] }

# Get Windows Backup Policy
Get-WBPolicy >WBPolicy

# Extract the line containing only the backuped items
select-string -pattern "VolumesToBackup" WBPolicy | foreach { $_.ToString().split("{")[1] } >BACKUPED

$notbackuped = ""

# Parse file with driveletters and check if they exist in the current backup-set
foreach ($line in $harddisks)
{
  $isbackuped = select-string -pattern $line BACKUPED
  if (!$isbackuped) {
    $notbackuped = "$notbackuped $line"
  }
}

# Write a dot for a system that has all harddisks backuped or the missing harddisks
if ($notbackuped) {
  Write-Host $notbackuped
}
else
{
  Write-Host "."
}

Somehow it just works.
No need to run it from an elevated command.
I didn't expect it to run because I needed to run powershell as administrator otherwise I couldn't even execute the first command (the snap-in).

But I was trying my Zabbix installer and noticed it just worked....

So... No questions.
Maybe move this thread to cookbook???

Now I need to install the new agent on all these Windows Machines....

Edit: It doesn't work in Windows 2008R2, I'm not really interested in why. These 2 clients are postponing that upgrade already too long... (not to mention 2 clients with 2003)
