In Storage Account, you can set diagnostic log to EventHub. However, did you ever wonder if you could have a centralized EventHub to take care of these logs? Instead of having multiple EventHubs across each Subscription within the same Management Group? In this article, it will explain to you how to centralize your EventHub.
I. What is the required Permission configuration?
Before reading through this article, be sure to have multiple subscriptions. As this will not explain the steps to add subscriptions to your Management Group. This article is based on the fact that you already have...
Scenario: PowerShell script to get the total number of partitions in Event Hub Namespace.
You must be wondering how to find out total number of partition count for any Event Hub namespace??
On the Azure portal you can only see partition count per Event Hub Entity level but not Namespace level. It’s tiresome job to manually sum up partition counts of all the entities especially when you have hundreds of event hub entities under the namespace.
Here is a simple way to find out total number of Partitions under Event Hub namespace using PowerShell script.
Solution:
Use below...
Few platform logs and metrics go missing when streaming them from Diagnostic Setting to Event Hub...
Issue: Few platform logs and metrics go missing when streaming them from Diagnostic Setting to Event Hub especially when Event Hub is Throttling.
Scenario: Using Diagnostic setting users route platform logs and metrics to Azure Event Hub (EH). These events are consumed by partner SIEM and Monitoring tools. At times users complain that events that occurred in the system or certain metrics\logs\traces has not reached the Event Hub.
Validation:
Validate if the event\metric\log has been generated by the platform\application. Also check if the Diagnostic setting is properly configured to...
Scenario: Calls to Service Bus and Event Hub failing with Server Error \ Internal Server Error \ HTTP Error 500 Errors.

The corresponding exception messages are something like this – “The server was unable to process the request due to an internal error”. The exception type and exception messages may vary somewhat based on the programming language of the SDK, SDK version, Wrappers, etc. There are a lot of frequently asked questions related to the Server Error and I...
Are you getting 50002 Error or 50008 Error return code in your EventHub? If that’s the case, you are in the right place.
In this documentation, we will go through what these two return codes are and how to prevent your EventHub to throttle.
[50002 Error - ServerBusyException]
Pre-requisite:
Are you getting 50002 Error from your EventHub? Is your Throughput appropriately configured? Is your load evenly distributed across all partitions? If so, keep on scrolling down, as you may find the answer to your problem.
I. What is a Throughput Unit?
The throughput capacity of Event Hubs is...
Case: In a situation, you observe your EventHub namespace is still incurring the cost, even though you are not doing any operations (read/write/management) on it and your EventHub namespace has no active EventHub instances present.
Root Cause of the behavior:
At the time of creating the Azure EventHub namespace (Basic/Standard/Premium/Dedicated tier), you may have to give pre-purchased units of capacity in terms of Throughput units/Processing units/Capacity units based on the tier you choose. These pre-purchased units of capacity controls throughput capacity of the EventHub...
