The schema of the events in the Storage account

  • A blob container is created for each event type:

    The Event Hubs with resource ID2

  • The schema of each row in a blob is the following JSON:

    {
      "time": "<The time WDATP received the event>"
      "tenantId": "<Your tenant ID>"
      "category": "<The Advanced Hunting table name with 'AdvancedHunting-' prefix>"
      "properties": { <WDATP Advanced Hunting event as Json> }
    }
    
  • Each blob contains multiple rows.

  • Each row contains the event name, the time Defender for Endpoint received the event, the tenant it belongs (you get events only from your tenant), and the event in JSON format in a property called "properties".

  • For more information about the schema of Microsoft Defender for Endpoint events, see Advanced Hunting overview.

  • In Advanced Hunting, the DeviceInfo table has a column named MachineGroup which contains the group of the device. Here, every event is decorated with this column as well. For more information, see Device Groups.

    Note

    Device group creation is supported in Defender for Endpoint Plan 1 and Plan 2.
