Format the results of a PowerShell script - powershell

Question

I'm trying to retrieve Azure service bus queues who has exceeded a specific message count, and the script is working well so far, but when it retrieves the values, it just does it in the following format:
The limit has been exceeded for the following queues:q1-monitoring-endpoint q1-monitoring-endpoint q2-monitoring-endpoint q3-monitoring-endpoint
I need to retrieve them in a better format.
Here is the script, I'm using:
$NS = Get-AzureRmServiceBusNamespace
foreach ($NS in $NS)
{
$Queue = Get-AzureRmServiceBusQueue -ResourceGroupName $NS.ResourceGroup -Namespace $NS.Name
if ($Queue.MessageCount -eq 0 )
{
"The limit has been exceeded for the following queues:" + $Queue.Name
}
}

Answer 1

I don't have access to an Azure subscription at the moment to test this, but consider doing something along these lines:
Get-AzureRmServiceBusNamespace |
ForEach-Object {
Get-AzureRmServiceBusQueue -ResourceGroupName $_.ResourceGroup -Namespace $_.Name |
ForEach-Object {
[PsCustomObject]#{
Queue = $_.Name
LimitExceeded = ($_.MessageCount -eq 0)
}
}
}
This will (hopefully) produce output similar to the following:
Queue LimitExceeded
------ -------------
Queue1 False
Queue2 True
Queue3 False
Not only is this a neater format than the original string output, it means you get some objects as output, which can be further manipulated.

You should explain "in a better format". However, your main issue is within your foreach loop where you try to iterate over $NS but assign the current object to $NS. You need to choose a different variable:
$NS = Get-AzureRmServiceBusNamespace
foreach ($N in $NS)
{
$Queue = Get-AzureRmServiceBusQueue -ResourceGroupName $N.ResourceGroup -Namespace $N.Name
if ($Queue.MessageCount -eq 0 )
{
"The limit has been exceeded for the following queues:" + $Queue.Name
}
}
Note: I would recommend to retrieve all empty queues and save it in a variable (which enables you to use it later):
$emptyQueue = Get-AzureRmServiceBusNamespace |
ForEach-Object {
Get-AzureRmServiceBusQueue -ResourceGroupName $_.ResourceGroup -Namespace $_.Name
} |
Where-Object MessageCount -eq 0
Finally, output it in your desired format:
Write-Host "The limit has been exceeded for the following queues: $($Queue.Name -join ',')"

You can try the Format commands available in powershell to get the output in a better format.
You can define your custom format as well with Format-Custom command.
