In my application all the events are getting stored in Azure service Bus queue, and another component reads that queue and process the events.We are using Azure-servicebus java sdk version 0.9.2.

After processing few thousand events we are getting below Service Bus error.

Caused by: com.microsoft.windowsazure.exception.ServiceException: WRAP server returned error acquiring access_token
Response Body: ACS90055: The server has terminated the request (tenant exceeded rate limit). Please wait a few seconds and try again.

It slows down my application. Also I am loosing lot of events.

How to get pass this error ?

How to fetch messages in a batch, Instead of fetching individual call for single message ?

Do we have Batch Receive support for Azure service bus Java SDK ? If no what other way we should follow for Java Application using Azure Service bus.

How to increase the rate limit for my tenant ?

Thanks, Abhi

I am trying to use an EventHubSender to send messages to an EventHub from within a cloud service.

My send code works in a unit test environment, but throws the following exception when exercised in the cloud service.

Any ideas?

Hi,

We are designing project now, our devices send data's to cloud frequently ( per second 10 request to cloud via multi thread )

Minimum 10000 devices going to use in live, so we are expecting request based on this 

Per Second = 100000 

1 Min =6000000

Per 1 hour = 360000000

Per Day = 8640000000

Plan to use Iot hub concept but like to know which one will be good to this case web api , iot hub , event hub or any other better option to handle these moare requests at same time also Iot& web api have any limitations ( Can able to handle this work load or not & which on is better )   Please provide some good idea on this .

Thanks,

Kumar

The issue is actually a more basic PowerShell / .NET 4.5 compatibility issue.  I believe all of the ServiceBus assemblies are dependent on .NET 4.5 runtime.

If I'm corresponding creating a PowerShell cmdlet configured in Visual Studio to use .NET 3.4, how to I get this to run inside the PowerShell shell?

e.g. calls like 

Microsoft.ServiceBus.Messaging.EventHubClient client = 
Microsoft.ServiceBus.Messaging.EventHubClient.EventHubClient.Create(eventHub);

Starting Sunday afternoon (April 17, PDT) I noticed a huge slowdown across all of my WebJobs. I let it go until yesterday, hoping it was a temporary problem. Yesterday I dug into the problem and narrowed it down to our Service Bus calls. They're taking at least one order of magnitude longer than before. This is most noticeable when completing messages (message.CompleteAsync()) but receiving messages is also quite a bit slower than before. Completing just one message takes between 5 and 20 seconds!

I'm on the US West region. The Azure status page shows no problems for Service Bus, but I'm wondering if something's been missed. Can someone check and verify there are no problems? I don't believe this is on my end. I have two Service Bus namespaces, one for test and one for production, and only the production one seems to be affected.

I followed some advice from someone experiencing a similar problem last year (http://stackoverflow.com/questions/29425653/azure-service-bus-queue-extremely-slow) and recreated all of the queues. This hasn't resolved the problem. We're not using partitioned queues, but our throughput isn't that huge (~3 messages per second across each queue).

We're hoping this can be looked into without having to pay for 6 months of support, since I believe this isn't on our end. I'd be happy to provide more info if needed...just let me know. Thanks much for your time!

No sure if this is the forum but we have been having "Exception=Microsoft.ServiceBus.Messaging.MessagingCommunicationException: The X.509 certificate CN=

I created an Event Hub about 300 hours ago (~10 days) and pushed about 700 events into the hub.  Today when I fired up Service Bus Explorer (i.e. 10 days later), I was very surprised to see the original events were still in the Event Hub.  The Retention Period was set for 1 day. ...so I expected by now that the partitions on my Event Hub would be empty (no events).

What's up? What are Event Hub Retention Periods supposed to do?  Are they working?

Hello,

Is there any plan on supporting Event Hub on Azure Pack?

Thanks

When I push a message trough the Service Bus and I want to fetch it with the REST API (trough the PHP SDK for example), a 500 Internal Server Error is thrown when the Message contains a Message Property with a key that contains a colon or a slash.

I store the message by using the Service Bus Explorer, and clicking on "send message" on a queue.

Under Message Properties, fill in xxx/yyy as key, with any value (type = string)

Hit [ Start ].

The REST API will throw an error like this when fetching this message.

Error: Fail:
Code: 500
Value: Internal Server Error
details (if any): <Error><Code>500</Code><Detail>The server was unable to process the request; please retry the operation. If the problem persists, please contact your Service Bus administrator and provide the tracking id. TrackingId:19476ab0-066a-4a47-8a56-a2d8614146d5_G5,TimeStamp:4/26/2016 1:03:27 PM</Detail></Error>.

I've stumbled on this bug when integrating with Microsoft Dynamics CRM, what pushes messages on the Service Bus with message properties that are all URLs in the keys.

I have a requirement of reading the value using client side application (javascript) and send it to the azure bus queue.

As this is completely client based application, I would like to use java script to write value to the queue.

Reason for avoid node.js was the installation part, which is not possible on all client machine (correct me if i am wrong).

if there is any alternative ways like Rest API...which does not require any installation kindly suggest.

as i am new to azure, i would appreciate complete code with example.

Hello,

Does anyone have any insight on whether the on premise version of the service bus will be supported in the foreseeable future? It seems that it hasn't been updated since 2013, even though a yearly update was promised. This gives me the impression this product will overcome the same fate as other on premise products such as App Fabric, i.e. will be discontinued. Would it be smart to use this product for new development? Is there any road map?

Hi,

One of my customer is having a web application developed in Python and hosted on Azure. The application helps users to take backups to azure storage from individual folders, virtual machines images and outlook mail and so on. Customer is planning to release this tool on Marketplace as a SaaS solution.

I remember back in days of Windows Azure training Kit (WATK), had a lab to configure applications on Azure Marketplace wherein step by step guide was mentioned to configure application as SaaS on Azure Marketplace. The high level steps were –

1.      Understanding SaaS subscription scenario
2.      Modifying application to support Azure Marketplace subscriptions
3.      Register application in Marketplace and Test subscription with Dev playground.
4.      And so on.

Do we have any such a lab existing today with latest changes and steps? Also the older lab was focusing on asp.net MVC application. Do we have similar stuff done for Python based application or Python web applications cannot be on Marketplace?

Please help.

Thanks, Manthan Upadhyay

hello, i created the IoT Hub in Azure and follow the tutorial in this link ( I code 100% like this)

https://azure.microsoft.com    /en-gb/documentation/articles/iot-hub-csharp-csharp-process-d2c/

I'm generating a SAS key by ruby. It generates some token, which seems correct but wrong. When I use this token, it returns '404 No value' Could someone help me to figure out what's wrong with the code?

Thank you in advance :)

Hi!

I have troubles writing unit tests of methods that uses BrokeredMessage, since I do not know how to set the state of the message. For example, I have message.Complete() inside a method that I want to test, but it throws exceptions since the message is not in the correct state. Any ideas of how to fix this?

This is the exception I get: System.InvalidOperationException : Operation is not valid due to the current state of the object.

Hi,

When trying to uninstall Service Bus i get this error:

"This computer is part of a farm. To uninstall, first leave the farm either using 'Leave from Farm' option in Service Bus Configuration tool or Remove-SBHost cmd-let in PowerShell."

When trying the Remove-SBHost powershell command I get this error:

"Remove-SBHost : Certificate requested with thumbprint EC808B911009F8A8E21FE73DE5216E6B596527F4 not found in the certificate store LocalMachine\My."

When trying to open the configuration tool it just craches with this information in the eventlog:

Application: Microsoft.ServiceBus.ConfigWizard.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Windows.Markup.XamlParseException

How can I uninstall the Service Bus?

Hi,

I want to use the ServiceBus queues/topics to control the flow of messages.

What I need is to do is to send messages to queues and I want these messages to be consumed by applications but I want to control the flow. For example, if I have 100 messages in the queue, I don't want the consumer to be able to receive more than 10 messages per seconds for example.

Is it possible with Service Bus?

Thanks.

I have encountered a strange error where messages directly get into dead letter queue without even processing. The QueueClient.Send() method directly inserts queue messages into dead letter queue.  Is this glitch?

However, I am inserting messages into  queue in a parallel.Foreach loop.

Hi all , I am trying to connect a intel Edison to IOT hub as to documentation on Azure at Git
