Create, view, and manage Event Grid system topics in the Azure portal

  • Article

This article shows you how to create and manage system topics using the Azure portal. For an overview of system topics, see System topics.

Create a system topic

You can create a system topic for an Azure resource (Storage account, Event Hubs namespace, etc.) in two ways:

  • Using the Events page of a resource, for example, Storage Account or Event Hubs Namespace. Event Grid automatically creates a system topic for you in this case.

    When you use the Events page in the Azure portal to create an event subscription for an event raised by an Azure source (for example: Azure Storage account), the portal creates a system topic for the Azure resource and then creates a subscription for the system topic. You specify the name of the system topic if you're creating an event subscription on the Azure resource for the first time. From the second time onwards, the system topic name is displayed for you in the read-only mode. See Quickstart: Route Blob storage events to web endpoint with the Azure portal for detailed steps.

  • Using the Event Grid System Topics page. You create a system topic manually in this case by using the following steps.

    1. Sign in to Azure portal.

    2. In the search box at the top, type Event Grid System Topics, and then press ENTER.

      2. Select the Azure subscription that has your storage account resource.

      5. Enter a name for the system topic to be created.

        Note

        You can use this system topic name to search metrics and diagnostic logs.

      6. Select Review + create.
