Hi All,
thanks for all your help, I got a bit further 
Now I'm having the problem that I can't get any useful data out of my array^^
I use this command to fill the associative array ergs, but later I can't get any data out of it:
$ergs=(Get-Pool | Select Pool_id,@{N="desktops";E={$_ | Get-DesktopVM | Measure-Object | Select -ExpandProperty Count}},maximumcount | Format-Table -AutoSize -HideTableHeaders)
Similar if I use $ergs["VALUE"] or echo $ergs["VALUE"] or $ergs[VALUE] or $ergs['VALUE'] result is empty.
If I just use echo $ergs i can see the set Values.
Any suggestions on this?
thx

Actually I'm building scripts sequentially and as this function($ergs=(Get-Pool | Select Pool_id,@{N="vdesk";E={$_ | Get-DesktopVM | Measure-Object | Select -ExpandProperty Count}},maximumcount)) is the first real custom code, I haven't much to show yet.
Currently I have only:
<Adding View cmdlets>
$chk=0
$outfile="D:\outtmp.txt"
Connect-VIServer -Server server.domain.net -Force >>null
$ergs=(Get-Pool | Select Pool_id,@{N="vdesk";E={$_ | Get-DesktopVM | Measure-Object | Select -ExpandProperty Count}},maximumcount)
(below is just coded here to see the direction I want to go..(no idea if it works atm))
$lim=$ergs.count
for ($i=0;$i -lt $lim;$i++)
{
[int]$cur=$ergs[$i].maximumCount*0.05
$erg=$ergs[$i].maximumCount-$ergs[$i].vdesk
if ($erg -lt $cur)
{
echo "Pool $ergs[$i].Pool_id is reaching its limit, currently $ergs[$i].vdesk of $ergs[$i].maximumCount in use!" >> $outfile
$chk=1
}
}
(end of firstcode here)
function sendmail($body)
{
$SmtpClient = new-object system.net.mail.smtpClient
$MailMessage = New-Object system.net.mail.mailmessage
$SmtpClient.Host = "server_ip"
$SmtpClient.Port = 25
$mailmessage.from = "test@test.com"
$mailmessage.To.add("test2@test.com")
$mailmessage.Subject = “Pool monitoring”
$MailMessage.IsBodyHtml = $true
$mailmessage.Body = "$body"
$smtpclient.Send($mailmessage)
}
$body=(Get-Content $outfile) -join '<BR>'
if ($chk -eq 1)
{
sendmail $body
}
del null
del $outfile
exit
PS: how the hell can I use the code highlighting here?

Yes you are right.
Before I test this nice function:
If I understand it corrct it send for every pool a seperate message?
Atm I plan to let the script run once a day because users aren't added in masses to the pools.
Therefore I have some time to react before a pool reachs the limit and I don't want masses of mails in my inbox because of this
Yeah, I understood it right but explained it false in my words^^
Atm I struggling which method I should use, either sending 1 mail with infos or seperate ones.
In our enviroment we have several pools for testing which are permanently full or some has set 0 as maximum which leads the "/" to "Attempted to divide by zero." errors.
Not sure if it is good to implement filter functions here, could be more work than worth it.
Yes true, unfortunately I'm coming very slowly through the endless possibilities of PS :smileygrin:
Yep, creating a task should be no problem
