Find Publishers of an Event Hub

Hello - Is there a way, from the Event Hub page on the Azure portal, to find which publishers are sending events to this Event Hub. The only way I can acheive this is to go on each publisher and look which Event Hub it is using (which is not very optimal when the number of publishers is high). Thank you.

Azure Service Bus SLA Interaction Between Message Lock and SLA

March 15, 2019, 9:51 am
$

My interpretation of the SLA, from the SLA documentation and this link:

https://social.msdn.microsoft.com/Forums/azure/en-US/9a95dcd6-ba25-4b2d-9f13-d3896261d8ac/service-bus-sla-what-does-it-really-mean?forum=servbus

Is that Azure Service bus considers outages or lack of communication of <1minute to be within SLA.  Does this same SLA apply to lock refreshes?  We currently refresh locks with 30 seconds remaining on the lock, but occasionally get large batch failures.  My interpretation would be that this is in line with Azure Service Bus losing communication for >30s, leading to locks expiring.

Is this a valid interpretation?  If this is a valid interpretation, I am assuming then that if I have a long running process, that I will be required to refresh earlier than with 30 seconds remaining on the lock?

Thanks!

Hi,

The farm creation was also successful but not the step when the Services are started. First it took a Long time for processing. Finally this error message was shown:

Access Message Content (Or Correlation ID) In Notify Exception in Message Handler

Hello,

We are using Service Bus to act as the producer for a compute intensive consumer.  We occasionally receive message lock loss, which is acceptable as it is at low frequency even on long running jobs.  However, in order to maintain accurate logs we want to correlate message lock losses consistently with the entity that is being processed so that we can determine if there is a correlation between message lock loss and message content.

Thanks,

I am using Apache Flink, and trying to connect to Azure eventhub by using Apache Kafka protocol to receive messages from it. I manage to connect to Azure eventhub and receive messages, but I can't use flink feature "setStartFromTimestamp(...)" as described in Apache Flink documentation. When I am trying to get some messages from timestamp, Kafka said that the message format on the broker side is before 0.10.0. Is anybody faced with this? Apache Kafka client version is 2.0.1 Apache Flink version is 1.7.2

Tried to use Azure-Event-Hub quickstart examples in consumer package added code to get offset with timestamp, it returns null as expected if message version under 0.10.0 kafka version.

List<PartitionInfo> partitionInfos = consumer.partitionsFor(TOPIC);
        List<TopicPartition> topicPartitions = partitionInfos.stream().map(pi -> new TopicPartition(pi.topic(), pi.partition())).collect(Collectors.toList());
        Map<TopicPartition, Long> topicPartitionToTimestampMap = topicPartitions.stream().collect(Collectors.toMap(tp -> tp, tp -> 0L));
        Map<TopicPartition, OffsetAndTimestamp> offsetAndTimestamp = consumer.offsetsForTimes(topicPartitionToTimestampMap);

I am trying to deploy two service bus namespaces in two different regions including an alias to pair them together. I am using an arm template to deploy. First time I deploy, when the resources doesn't yet exist it goes OK and the resources are created. Trying again with same template I get following response after 10 min:

{"code": "DeploymentFailed","message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.","details": [
    {"code": "RequestTimeout","message": "{\r\n  \"error\": {\r\n    \"code\": \"ResourceDeploymentFailure\",\r\n    \"message\": \"The resource provision operation did not complete within the allowed timeout period. Please see https://aka.ms/arm-deploy for usage details.\"\r\n  }\r\n}"
    }
  ]
}
I get the RequestTimeout when creating the Microsoft.ServiceBus/namespaces/disasterRecoveryConfigs.

      ]

The template is according to 101-servicebus-create-namespace-geo-recoveryconfiguration from azure-quickstart-templates

Hello,

I was wondering if anyone has had this issue kind of issue before with Azure Service Bus and what would cause these random unwanted "Requests" to show up?

I create a new Service Bus and within a few minutes of it being created I was receiving "Requests". This was confusing for me because I had yet to create a queue or even setup an application to use the Service Bus.

I can see the "Requests" on the Overview screen where there are two line graphs showing "Requests" and "Messages".

How to TTL behave on Azure Service Bus Topic Subscriptions

We have a Service bus Topic which has a Message time to live (default) set to 14 days.

We have several subscriptions to this topic which have their own default TTL which is set to a value different than that's on the Topic. None of them exceed 14 days.

I have been looking for documentation around the behavior here with different TTLs. Does the TTL on the Subscription take priority over the Topic?

Will the message TTL irrespective of if there is a listener listening on one of the Subscription? i.e. if one of the Subscription (with TTL 5 min), has no listener currently connected to it and consuming messages. Will all messages TTL there after 5mins?

Alert Conditions Can No Longer Be Set

Hello!

I was creating alert rules for my service bus namespace recently, and ran into an unusual issue.  I defined a "Count of dead-lettered messages in a Queue/Topic" signal; and after that I couldn't specify the list of entities (queues) in Dimension Values section. Each time I try to check something from the droplist, it just collapses without checking anything, so I can't pick any queues from the list. It started happening suddenly and everything worked the way it should just a couple of minutes before and never since.

It appears to be some kind of a bug.

I tried clearing caches, different browsers and different accounts, checking checkboxes with page source, to no avail.

Could you please explain what could cause this issue? Maybe there is a way to set alert rules with the cloud shell?

Integrate TomEE with Azure Service Bus for JMS

I want to switch the JMS implementation from ActiveMQ to Azure's Service Bus. Currently, we are using ActiveMQ but want to explore the option of switching to Azure Service Bus. However, I'm getting exceptions when deploying my simple JMS application.

I'm using TomEE [8.5.32 (7.1.0)]. I include the AMQP 1.0 JMS client library jars to the lib directory of TomEE. (See: https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-java-how-to-use-jms-api-amqp)

    ResourceAdapter = amqpsRA</Resource><Resource id="MyQueue" type="javax.jms.Queue"/><Resource id="MyTopic" type="javax.jms.Topic"/>

Unfortunately, when I deploy my JMS application I get the following exception:

Unable to create activation spec: connectionFactory is mandatory

Has  anyone been able to get TomEE to work with Azure Service Bus?

Thanks!

Service Bus Message Can Be Peeked But Not Received From One Specific Computer

I have a C# dotnet application that sends and receives messages through service bus topics+subscriptions using Microsoft's messaging client SDK v3.  On one customer's server I can execute a Peek command on a topic subscription and see there is a message available to receive.  However, when attempting to Receive the message, the operation returns null after timing out, as if there is no message available.  

I've written a test app to reproduce this and can verify the Receive executes successfully from my a different computer in the customer's office but will *not* Receive from this one specific system.

I would greatly appreciate any guidance you can provide on what I might look for to explain this isolated behavior and things I might try to resolve the problem?

Azure Service Bus Topic multiple listeners receive same message

Hi Team,

I have a situation where i am trying to implement pub/sub pattern.

Using Azure i am publishing message and coming to client if two clients are subscribed to same topic & subscription only one of it is getting message other client is not getting.

To put it simple:

I am broadcasting message and two persons are subscribed to my Topic. When i broadcast message only one person is getting that message other doesn't get. Below is sample code.

 subscriptionClient = new SubscriptionClient(sbConnectionString, sbTopic, sbSubscription);

                var messageHandlerOptions = new MessageHandlerOptions(ExceptionReceivedHandler)
                {
                    MaxConcurrentCalls = 100000,
                    AutoComplete = false,
                };
                subscriptionClient.RegisterMessageHandler(ReceiveMessagesAsync, messageHandlerOptions);
static async Task ReceiveMessagesAsync(Message message, CancellationToken token)
        {
            Console.WriteLine($"Subscribed message: {Encoding.UTF8.GetString(message.Body)}");

            //await subscriptionClient.CompleteAsync(message.SystemProperties.LockToken);
        }

Please let me know if i am missing anything or Azure Service topic is wrong option in this case.
