  • Monitor net savings and waste in real-time.
  • View Effective Savings Rate (ESR) to measure overall performance.
  • Compare on-demand equivalent costs against actual spending.

Multi-Dimensional Filtering

Access granular views of your reservations through customizable filters:

  • Date Range: Analyze historical trends or focus on specific periods.
  • Service: Filter by AWS Services to understand service cost distribution.
  • Region: Filter by AWS region to understand geographic cost distribution.
  • Linked Account: View utilization across organizational accounts.

Performance Graphs

Utilization Graph

The utilization graph displays the Daily/Monthly utilization percentage over time. and helps identify usage patterns and trends. Supports daily and monthly views.

  • Umbrella is using AWS GET RI Utilization API to retrieve the utilization data per all plans combined and per the plan.
  • Required permissions ce:GetReservationUtilization.

Coverage Graph

The coverage graph tracks coverage stability over time and shows the percentage of eligible usage covered by Reserved Insurance commitments.

  • Umbrella is using AWS GET RI Coverage API to retrieve the utilization data per all plans combined and per the plan.
  • Required permissions ce:GetReservationCoverage.

    • Start Date: When the plan became active

    • End Date: Plan expiration date

ChargeBack

The Chargeback view shows how a Reserved Instance commitment is consumed across your AWS resources. Each resource is charged based on its actual usage that benefited from the Reserved Instance.

With the Chargeback view, you can:

  • See which resources consumed the Reserved Instance.
  • Understand how much of the commitment was applied to each resource.
  • Accurately allocate discounted costs for chargeback or showback purposes.

Overview Charts

This view shows the utilization for the selected Reserved Instance commitment.

RI Flexibility

The list provides a breakdown of actual resource usage that consumed the Reserved Instance benefit, including:

  • Usage date when the RI was applied.
  • Resource ID and type (for example, EC2 or RDS instance types like r6g.xlarge).
  • Linked account where the benefit was used

Whether the RI was applied to a different resource than originally purchased, which demonstrates size or resource-level flexibility

In short, this view helps you validate RI flexibility behavior, understand where the reservation discount is applied, and identify whether flexible RIs are being effectively utilized across eligible resources and accounts.
