Fabric and Azure events support event-driven scenarios like real-time alerting and triggering downstream actions. Publishers like Azure Storage or Fabric Workspaces emit events that are received by consumers like Activator or Eventstreams to enable you to monitor and react to events by triggering actions or workflows.
Note
In this article, Fabric events refer to both events generated within Fabric and also Azure events.
When you use a Fabric capacity, your usage charges appear in the Azure portal under your subscription in Microsoft Cost Management. To understand your Fabric billing, visit Understand your Azure bill on a Fabric capacity.
Fabric and Azure events usage is defined by two operation types, which are described in the following table. The table provides information about Fabric and Azure events operations shown in the Fabric Capacity Metrics app and their Fabric consumption rates. For more information about the app, see Microsoft Fabric Capacity Metrics app.
Operation in Capacity Metrics App | Description | Operation unit of measure | Fabric consumption rate |
---|---|---|---|
Event operations | Publish, delivery, and filtering operations | Per event operationNote 1 | 0.000011111 CU Hour |
Event listener | Uptime of the event listener | Per hour | 0.0222 CU Hour |
Event operations represent operations for publish, filtering, and delivery of events. For Fabric and Azure events generated in Fabric, the publish operation charge doesn’t kick in until a consumer is established for these events. The publish operations are charged to the publisher’s capacity, while the filtering and delivery operations are charged to the consumer’s capacity.
For example, when a Fabric Activator trigger is created to take an action on a workspace item event, the source workspace’s capacity is charged for the publish operations, and the Activator’s capacity is charged for the filtering and delivery operations.
The following operations are the different types of Event Operations:
This meter kicks in when a consumer is created for Fabric and Azure events and is charged to the consumer’s capacity. For example when an Activator trigger is created to act on an event, this meter is charged per hour during the existence of this trigger.
The Microsoft Fabric Capacity Metrics app is designed to provide monitoring capabilities for Microsoft Fabric capacities. Use the app to monitor your capacity consumption and make informed decisions on how to use your capacity resources. For example, the app can help identify when to scale up your capacity or when to turn on autoscale.
In the app, the event operations show the metadata of the publisher for the publish operations and the metadata of the consumer for the delivery and filtering operations. For example, when an Eventstream source is created to consume an event, the Event Operations for delivery and filtering as well as the Event Listener operation shows the metadata of the Eventstream artifact.
Note
When an Activator trigger is created to take an action on an event, the Event Operations for delivery and filtering as well as the Event Listener operation show the metadata of the Activator artifact, under the ReflexProject Item Kind.
In some cases, the publisher or the consumer can be nonartifacts. For example, for workspace events, the publisher is the workspace. In these cases, the publish operations shows:
FabricEvents-"<event category>
, and for workspace item events, the Item kind is FabricEvents-WorkspaceItemEvents
.Consumption rates are subject to change at any time. Microsoft uses reasonable efforts to provide notice via email or through in-product notification. Changes shall be effective on the date stated in Microsoft’s Release Notes or Microsoft Fabric Blog. If any change to a Microsoft Fabric Workload Consumption Rate materially increases the Capacity Units (CU) required to use a particular workload, you can use the cancellation options available for the chosen payment method.
