Could anyone help me to understand in session enabled queue/topic, how to recognize session start and end when sending/receiving messages? And is it always compulsory to start/end sessions?

How to enable Azure Event Grid Webhook to Azure VM
We're using Azure Event Grid Webhooks (https://docs.microsoft.com/en-us/azure/event-grid/receive-events) with the endpoint configured as a server running in an azure virtual machine.
The VM is running with a security group that only enables known addresses. The problem is that the source of these events, (somewhere in Azure is not known. Therefore we currently have to disable the security group, sniff the source of the events, and <g class="gr_ gr_10 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del" data-gr-id="10" id="10">reenable</g> the security group with allowing the source IP. Is there a better way to go about this then doing this for all possible sources?
If not, is there a means of getting the source addresses of these events somehow?

Unit test BrokeredMessage
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.

Inspect server errors from storage account
I have configured several event hubs. I connect to these hubs using the Spark event hub connector.
After successfully processing numerous of messages I encountered problems now. My Spark app does not consume any messages anymore (without any exceptions) but in the Event hub portal view I see some server errors in the charts.
I configured to output logging to storage account (in the diagnostic settings), but when I try to view the logs in my storage account (using the Storage Explorer) I do not see any logging (only some general metrics).
How can I view the reported server errors from my storage account?

Load balancing consumer with Azure Topics
I want to know how i can achieve below behavior using Azure Service Bus Topics.
Sender sends different message (say A1, B1, C1, A2, B2, C2). Service1 should process messages of type A , Service 2 should process messages of type B and so on.
But if i have 2 instances of Service1, how can i ensure that a message of type A is received by only one of them. I need two instances of Service1 as this task is resource-intensive and huge requests are expected for this.

Avoid Converting DateTimeOffset to UTC time in Azure EventGrid
I've been testing out Azure's EventGrid and one of the things I'm trying to do is send an event where part of the PayLoad is a DateTimeOffset field. I'm publishing the event using the standard EventGridClient:
using (var client = new EventGridClient(topicCredentials))
{
await client.PublishEventsAsync(topicHostname, eventGridEvents).ConfigureAwait(false);
}I've fired up Fiddler and verified that the date portion is getting serialized as I would expect: "CheckInDate": "2018-12-26T14:47:42.8-08:00"
But when my subscribed Azure Functions listener receives the HttpTrigger and reads the message's content, the same item has somehow been formatted as UTC: "CheckInDate": "2018-12-26T22:47:42.8+00:00".
Is there a setting or something I need to enable to get it to preserve the original offset?

Azure Service Bus: single producer and multiple consumers scenario for Service Fabric applications
I am new to Azure Service Bus and having a difficult time wrapping my mind around a few concepts, so any help is greatly appreciated!
I have distributed (Service Fabric) applications, say A and B where each consists of instances running on different nodes (say A1, A2, B1, and B2). There are two scenarios that I need to support:
- a producer publishes a single message and EVERY consumer receives it (A1, A2, B1, B2)
- a producer publishes a single message and a single instance per application receives (say A2 and B1)
Should I be publishing a message to a queue and then forward it to another set of queues?
Thank you in advance and my apologies if I didn’t ask this in the right forum.

Problems with AZURE SERVICE BUS QUEUES
Hello everybody!
I am developing a JAVA Service that requires two different processes, one is the REST service, an the other one the WORKER SERVICE. There is a QUEUE between both services. The REST service sends messages with info to the worker, and the worker processes those messages that arrive in the queue.
I would like to know if it is possible that once the message is treated, we can update it in the queue, and that it is accessed through the REST services again with the message identifier in the queue. And finally to be able to eliminate this message once treated and recovered.
So my question is that if once the message is taken from the queue, this message is deleted or can we return it to the queue to access the final result?

Integrating with Salesforce Platform Events
Is there anything in the roadmap which will support utilizing Service Bus, Logic Apps in order to integrate with Salesforce Platform Events?
I'm happy with the features available in Logic Apps and Service Hub which lets me integrate with Outbound Messaging in Salesforce. But, Outbound messaging has its own flaws and messages may go missing without a way to track success - whereas Platform Event subscriptions have the status and retries.

I have tried on Windows 10 and Windows Server 2016. All I want to do is set up a hybrid connection relay"
The conclusion the agent came to was that Server 2016 is not supported but this doesn't sound right to me. Could I be missing some pre-requisites on the server?

Service Bus Disaster swap exception type and how to do a drill
Hello,
We are integrating disaster recovery to our solution based on service bus. Following the Active-Passive pattern as implemented in this repo: https://github.com/Azure/azure-service-bus/blob/master/samples/DotNet/Microsoft.ServiceBus.Messaging/GeoReplication/SenderPassiveReplication/Program.cs#L59
Our question is, what type of exception should be the condition to perform the swap?
Is there a way that we can simulate the outage to test the solution?
Thank you.

Messages transferred automatically from "active message" to "dead letter queue"
Hi,
I would like to understand the behaviour of service bus regarding the dead letter queue.
We are using service bus premium.
I send message to a queue in order to reach the queue size limit.
When the queue is full, let's say I have 20k messages in the "active message count" and 0% free space.
When the queue is full, I stop sending new messages.
The next morning, I can see that all my 20k messages are now in the dead letter queue and my queue is still at 0 % free space.
If I read the message in the dead letter queue, I can notice that the reason is : 'MaxDeliveryCountExceeded': 'Message could not be consumed after 10 delivery attempts.'
Can anyone explains this behavior ?
Thanks
