Introducing the Item History Page in Microsoft Fabric Capacity Metrics App (Preview)
We’re thrilled to announce the Preview of the Item History page in the latest version of the Microsoft Fabric Capacity Metrics App. The Item History page provides a 30-day compute usage analysis through dynamic visuals and slicers, enabling users to explore both high-level consumption trends and granular item-level metrics. This page helps you understand how individual items and operations contribute to overall capacity usage.
Key Features
- Slicers: Filter by ‘capacity name’, ‘workspace’, ‘experience’, ‘operation’, ‘run by’ and ‘billing type’.
- Aggregate Compute Consumption
- CU(s) by workspace: Filter which workspaces are consuming the most capacity units.
- CU(s) by item: Filter which items are consuming the most capacity units.
- Smoothed CU% over time: Filter background vs. interactive operations and identify overloads with the CU % limit line.
- Workspace details: Indicates aggregated workspace-level usage metrics such as operations pass rate, number of operations and % compute consumed.
- Item History
- Scheduling Frequency: Indicates the number of operations by date.
- % breakdown by status: Indicates the percentage distribution of operations based on their completion status.
- CU(s) by date: Displays CUs by date.
- Item details: Find detailed item-level usage data such as date scheduled, % compute consumed, status and number of seconds of throttling applied.
These visuals empower users to pinpoint bottlenecks, optimize workloads, and plan capacity upgrades with confidence.
Example: How the Item History Page appears.

Use Cases
- Capacity Planning: Identify items that consistently consume high CU and forecast future needs.
- Usage Trends: Identify usage trends for items and workspaces to understand their impact on CU usage over time.
The release of the Item History page is another step in our journey towards transparent, real-time, and actionable capacity monitoring. We’d like to encourage everyone to explore the new page and share feedback to help shape its evolution.
