Determining how many messages are on the Azure Service Bus Queue

Question

I know there is a way to determine the number of messages (or approximate number) in the Azure Queue (Store Account); however is there a way to query for the number of pendi

Answer 1

I've spent good 2 hours digging through docs to get that and for people using .net core and Microsoft.Azure.ServiceBus nuget package, code looks like that:

var managementClient = new ManagementClient("queue connection string"));
var runtimeInfo = await managementClient.GetQueueRuntimeInfoAsync("queueName");

var messagesInQueueCount = runtimeInfo.MessageCountDetails.ActiveMessageCount;

Aparently you get the information about all Counts(including deadletter, active, etc.) from QueueRuntimeInfo object instead of old QueueDescription object.

Answer 2

have you looked at the Queue Description API? There's a property called MessageCount.

Here's the .NET SDK reference documentation page as well.

Answer 3

As per the recommendation by Microsoft, it is recommended to use Microsoft.Azure.ServiceBus in which you can easily fetch the message count by

var managementClient = new ManagementClient("connection string for queue");
var queue = await managementClient.GetQueueRuntimeInfoAsync("queue name");
var messages = queue.MessageCount;

Answer 4

It is called MessagesCountDetails.ActiveMessageCount. It returns the number of the Active Messages in the Queue. You probably have some Dead letter messages:

var msg = Microsoft.ServiceBus.NamespaceManager.CreateFromConnectionString(Settings.Default.ConnectionString);
numofmessages.Text = msg.GetQueue(QueueName).MessageCountDetails.ActiveMessageCount.ToString();

Answer 5

Here's a PowerShell example to continually eyeball the queue length as used in Azure Portal Cloud Shell

cd "Azure:\<MySubscription>\"
while (1) {(Get-AzureRmServiceBusQueue -ResourceGroup <myRG> -NamespaceName <myNS> -QueueName <myQueueName>).CountDetails | Select -expand ActiveMessageCount}

Answer 6

var nsmgr = Microsoft.ServiceBus.NamespaceManager.CreateFromConnectionString(connectionString);
long count = nsmgr.GetQueue(queueName).MessageCount;
