Analyze streams

To analyze a stream whose parent is an eventstream, do the following steps:

  1. Open the eventstream associated with the data stream in Real-Time hub.
  2. Add a KQL Database destination to the eventstream to send the data to a KQL table.
  3. Open KQL database and run queries against the KQL table.

The following sections provide more details about these steps.

Open eventstream

In Real-Time hub, when you get events from the supported sources, an eventstream is created for you. You can open the eventstream by using one of the following ways:

  • Get events experience:

    At the end of creating this stream, on the Review and create page, you see the Open eventstream link to open the eventstream associated with the stream in an editor. -All data streams page:

Add KQL Database destination to the eventstream

After you open an eventstream in the editor, you can add a KQL database destination. When data is output to a KQL table, you can run queries against the KQL table to analyze the data.

  1. After you open the eventstream, select Edit on the ribbon to enter into the edit mode.
