[QUERY] Determine length (count of messages) in subscription

[lordarcy]

Query/Question
I have a program that is polling a subscription using a message receiver and the receive method to request new messages. Is there a way to monitor the length of the subscription so that a separate application can monitor the message count and see if everything is working.

Why is this not a Bug or a feature Request?
I don't know if the function already exists so I'm not making a feature request yet.

Setup (please complete the following information if applicable):

• OS: RHEL 8.x
• IDE : IntelliJ
• 3.5.1

@lordarcy Thank you for trying our library. Appreciate it.

You are using library 3.5.1 and you should be able to use ManagementClient.getSubscriptionRuntimeInfo() .

https://docs.microsoft.com/en-us/java/api/com.microsoft.azure.servicebus.management?view=azure-java-stable

https://docs.microsoft.com/en-us/java/api/com.microsoft.azure.servicebus.management.subscriptionruntimeinfo.getmessagecount?view=azure-java-stable#com_microsoft_azure_servicebus_management_SubscriptionRuntimeInfo_getMessageCount__

We also have new library v7.0.0 and if you upgrade to this , @ https://search.maven.org/artifact/com.azure/azure-messaging-servicebus
You can use ServiceBusAdministrationClient to get count of messages.

        // Create a administrator client using connection string.
        ServiceBusAdministrationClient client = new ServiceBusAdministrationClientBuilder()
            .connectionString(connectionString)
            .buildClient();

        SubscriptionRuntimeProperties properties = client.getSubscriptionRuntimeProperties("topicName", "subscriptionName");        
        System.out.printf("Total message count: [%d].%n", properties.getTotalMessageCount()));

ServiceBusAdministrationClient : This is normally used CRUD operation on the resources like subscriber/queue.
If you need additional information , please let us know.
