Help with powershell script

Question

I have an powershell commando that pulls all my machines of xenapp 7.6 that are registered.
But i want my script to show me output when an machine is unregistered. Can any one help me out with the if and else statement.
This is for registered machines:
Get-BrokerMachine | select MachineName, RegistrationState | Where { $_.RegistrationState -eq 'Registered' }
Th is for Unregistered servers:
Get-BrokerMachine | select MachineName, RegistrationState | Where { $_.RegistrationState -eq 'UnRegistered' }
Output is like this:
MachineName                                                                                          
RegistrationState
XXX\wsgrswxa01                                                                                               
Registered
XXX\wsgrswxa02                                                                                               
Registered
XXX\wsgrswxa03                                                                                               
Registered
I tried a little bit with if and else statement. But i don't know how to do it.
(example):
if(?)
echo “OK status – All XenApp machines or OK”
exit 0 #Return OK status
else
echo “CRITICAL status – These Machines(xxxx,xxxx) are Unregistered”
exit 2 #returns critical status
Can anyone help me out?

Answer 1

Hi,
you do that by 1) saving the query for unregistered machines, 2) Checking whether there are any unregistered Machines from that variable and 3) Writing down the names (again from the variables).
Cheers,

oh, ok, here you go :)
$Machines = Get-BrokerMachine | Where { $_.RegistrationState -eq 'UnRegistered' }
if (($Machines | Measure-Object).Count -gt 0)
Write-Output "CRITICAL status – These Machines ($(($Machines | Select-Object -ExpandProperty MachineName) -join ",")) are Unregistered"
exit 2
else
Write-Output "OK status – All XenApp machines or OK"
exit 0
There's no place like 127.0.0.1
