If you haven’t already, check out Arun Ulag’s hero blog “FabCon and SQLCon 2026: Unifying databases and Fabric on a single, complete platform” for a complete look at all of our FabCon and SQLCon announcements across both Fabric and our database offerings.
Customers use Eventstream in Microsoft Fabric to ingest and process streaming data at scale. They use Fabric Activator to monitor conditions and initiate actions when thresholds are met or specific patterns are detected. Now, we’re bringing these experiences closer together.
You have the ability to create and manage Activator rules directly within Eventstream in just few clicks, making it faster and simpler to turn events into action. Previously, setting up an alert required switching from Eventstream to Activator. While powerful, this meant moving between experiences to complete a single workflow. Now, alert creation is embedded directly into Eventstream. To learn more, refer to our Set alert on an eventstream with Activator destination documentation.
What’s new
- Create Activator rules directly inside Eventstream.
- Define rule conditions to specify the values you want to monitor in your events.
- Configure actions such as notifications or workflows.
- View and manage all rules associated with that Eventstream.
Why this matters
- Faster setup & reduced context switching - No more navigating between items. Create alerts while setting up your Eventstream.
- Full visibility - Easily see all rules tied to a specific Eventstream, improving operational clarity.
How it works - When building or editing your Eventstream, you can:
- Select the stream you want to monitor
- Choose Set Alert
- Define your condition (thresholds, aggregations, patterns)
- Configure the action
- Create the rule

Once you have the rule(s) created on your Eventstream, you can manage them by editing, deleting or opening in Activator.

By opening the rule in Activator:
- Manage the rule: View and manage all rules and actions created on your data, build additional business objects to validate hypothesis, and modify and delete them.
- Edit the rule: Tweak the settings and get an instant preview of how your edits affect the activations.
- Monitor and analyze the rule: View step-by-step how this rule is computed. Review its history of activations.
- Test/activate the rule: Send yourself a test alert and check your chat messages in Teams.
