Fabric Capacity Events in Real-Time Hub (Preview)
This highly requested feature is designed to give organizations real-time visibility and control over their Microsoft Fabric capacity resources to take the actions necessary to keep their capacities running.
Capacity overview events include two event types:
- Capacity Summary: These events provide a high-level understanding of capacity, including helping administrators monitor overall health and utilization. These events are smoothed and emitted every 30 seconds.
- Capacity State: These focus on the current state of the capacity (e.g., is it paused or is it overloaded due to throttling) and are emitted as events occur.
As part of this, there has been a community effort to build an accelerator that has out of the box templates, configurations, and other goodness to reduce time-to-value and maximize the impact of these features.

Example scenarios
With access to real-time capacity information through capacity overview events in Real-Time Hub, customers can monitor capacities and respond appropriately to events. This can be accomplished by utilizing Activator to take action or by leveraging Eventstream and Eventhouse to consume and process the data.
For instance, consider the following scenario:
‘As a Capacity Administrator, I would like to receive a notification in Teams if the interactive delay capacity percentage approaches 95%‘.
To implement this, users can simply navigate to the Real-Time Hub and configure an Activator to listen for events where the property ‘interactiveDelayThresholdPercentage’ exceeds 95. When this threshold is reached, the system will automatically send a message to the designated team.
Let’s consider another scenario:
‘As a Capacity Administrator, I want to extract, perform complex operations on, and store all events occurring within my capacity, while maintaining a comprehensive history of these events‘.
In this case, an Eventstream would be configured to receive data from one or more capacities, subsequently storing the information in an Eventhouse for advanced analysis or long-term retention.
