Discrepancy between Azure cost analysis and OptScale cost explorer

[valent]

Describe the bug
I have two Azure subscriptions: one for production and one for development. OptScale successfully retrieves all resources and their associated costs but fails to include charges that are not directly tied to a specific subscription. For example, costs related to Reserved Instances (RIs) or Savings Plans for VMs and managed databases are missing.

To Reproduce
Steps to reproduce the behavior:

1. Add one or more Azure subscriptions to OptScale.
2. Ensure there are additional charges, such as Reserved Instances or Savings Plans for VMs and managed databases.
3. Compare the total cost displayed in Azure with the cost reported in OptScale.
4. Notice that some charges are missing in OptScale.

Expected behavior
All resources and associated costs under each subscription should be accurately listed in OptScale. Additionally, any other charges, such as Reserved Instances, Savings Plans, and other compute-related commitments, should be included to reflect the total cost as seen in Azure.

Hi @valent, please tell me which Expense import scheme you use. You may find this information in OptScale on Azure data source details page on "Details" tab:
