Use hunting livestream to create interactive sessions that let you test newly created queries as events occur, get notifications from the sessions when a match is found, and launch investigations if necessary. You can quickly create a livestream session using any Log Analytics query.

Important

Microsoft Sentinel is now generally available within the Microsoft unified security operations platform in the Microsoft Defender portal. For more information, see Microsoft Sentinel in the Microsoft Defender portal.

Create a livestream session

You can create a livestream session from an existing hunting query, or create your session from scratch.

  1. For Microsoft Sentinel in the Azure portal, under Threat management, select Hunting.
    For Microsoft Sentinel in the Defender portal, select Microsoft Sentinel > Threat management > Hunting.

  2. To create a livestream session from a hunting query:

    1. From the Queries tab, locate the hunting query to use.
    2. Right-click the query and select Add to livestream. For example:

  3. To create a livestream session from scratch:

    1. Select the Livestream tab.
    2. Select + New livestream.

  4. On the Livestream pane:

    • If you started livestream from a query, review the query and make any changes you want to make.
    • If you started livestream from scratch, create your query.

    Livestream supports cross-resource queries of data in Azure Data Explorer. Learn more about cross-resource queries.
