RabbitMQ Web Interface - doesn't show queue until queue read? - rabbitmq

Question

I have a Powershell that sends a message to Rabbit-MQ. I've seen the same from BizTalk. The new queue name does not show up on the web interface until a message is retrieved from that queue at least one time. Is this the normal process? I don't understand why it wouldn't show up as soon as data was written to it.
Similar, I seem to be noticing that I can't store records in the queue until it is read once. I'm sending to an exchange with a routing key. If I write a program and send 5 messages there, the queue doesn't show up in RabbitMQ. But once I create a program to read/listen to that queue, from then on it shows up with the count of messages.
Sample Powershell Code:
Import-Module PSRabbitMQ
Set-RabbitMQConfig -ComputerName localhost
$User = "myuser"
#The second command uses the ConvertTo-SecureString cmdlet to create a secure string from a plain text password. The command uses the *AsPlainText* parameter to indicate that the string is plain text and the *Force* parameter to confirm that you understand the risks of using plain text.
$PWord = ConvertTo-SecureString -String "mypassword" -AsPlainText -Force
#The third command uses the New-Object cmdlet to create a **PSCredential** object from the values in the $User and $PWord variables.
$CredRabbit = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $User, $PWord
#Set some common parameters we will always use:
$Params = #{
Credential = $CredRabbit
}
$Exchange = "MyExchange"
$RoutingKey = "NealTest3"
$showDate = Get-Date -DisplayHint Date
$numMessagesPerRun = 5
for ($j=1; $j -le $numMessagesPerRun; $j++)
{
$message = "Hello at date/time= $showDate " + $j
Write-Host "Message = $message"
Send-RabbitMQMessage -Exchange $Exchange -Key $RoutingKey -InputObject $message -vhost base -Persistent #Params
}
$showDate = Get-Date -DisplayHint Date
Write-Host "Ended $showDate"
My Queue: NealTest3 will not show up when I do "rabbitmqctl list_queues -p base" until I run another Powershell to consume at least one message from that queue.
Code from second program to read the queue (left out the same logon info):
Start-RabbitMqListener -Exchange $Exchange `
-Key $QueueName `
-QueueName $QueueName `
-AutoDelete $false `
-vhost base `
#Params | % {
#$req = $_ | ConvertFrom-Json
$req = $_
$counter = $counter + 1
Write-Host $counter + " " + $req
}
It reads the 5 messages I put there, even though the queue in theory didn't exist, according to the list_queues.
