How to add a valid Alert to eventstream?

To add a valid alert to an eventstream in Microsoft Fabric Real-Time Intelligence, use this flow:

1. Open the eventstream.
2. If the eventstream is in Edit mode, select Publish on the ribbon.
3. Confirm the eventstream is in Live mode.
4. Select Set alert on the ribbon.
5. In the Add rule pane:
   1. Enter a Rule name.
   2. In Condition, choose one of these options:
      • on each event
      • On each event when
      • On each event grouped by
   3. In Action, select the action to perform when the condition is met. Supported actions include Microsoft Teams messages, email, webhooks, or Power Automate.
   4. In Save location:
      • Select the Workspace.
      • For Item, either select an existing Activator item or Create a new item.
      • If creating a new item, enter the New item name.
6. Select Create.
7. In the Alert created pane, select Done or Open to open the Activator item.

A valid alert creates an Activator destination automatically in the eventstream.

If the UI looks different in the current Fabric trial version, the current documented path is still: Publish → confirm Live mode → Set alert → configure Add rule → Create.

After the alert is created, rules can be managed from the eventstream:

• Select the alert icon on the Activator destination.
• In the Rules pane, view rules, stop or start a rule, edit, delete, open it in Activator, or add more rules.

Example from the tutorial:

• Rule name: No bikes available in bike station
• Check: On each event when
• Grouping field: BikepointID
• When: No_Bikes
• Condition: Decreases to or below
• Value: 0
• Action: Message to individuals
• To: Teams account
