Last updated: October 26, 2023

This guide walks you through the steps to create an Event Hub within an existing Event Hubs namespace using the Azure portal.

Prerequisites

• An Azure subscription. If you don't have one, create a free account.
• An existing Azure Event Hubs namespace.

Steps to Create an Event Hub

Using the Azure Portal

1. Navigate to your Event Hubs Namespace:

   Sign in to the Azure portal. In the search bar at the top, type "Event Hubs namespaces" and select it from the results. Select your existing namespace from the list.

   
2. Open the Event Hubs section:

   In the left-hand menu of your namespace, under "Event Hubs", select Event Hubs.

3. Create a new Event Hub:

   Click the + Create button at the top of the Event Hubs list.

   
4. Configure Event Hub settings:

   In the "Create Event Hub" pane that appears, you'll need to provide the following information:

   • Name: Enter a unique name for your Event Hub. Event Hub names must be between 1 and 256 characters and can contain only letters, numbers, hyphens, and underscores.
   • Partition Count: (Optional) Specify the number of partitions. Partitions are ordered, immutable sequences of events. The default is 2.
   • Message Retention: (Optional) Set the retention period for messages. This is the duration for which the Event Hub stores events. The default is 1 day.
   
5. Create the Event Hub:

   Click the Create button at the bottom of the pane.

You will see a notification indicating that the Event Hub is being created. Once successful, your new Event Hub will appear in the list of Event Hubs within your namespace.
