@Dilip Sasikumar - A subscription owner, or anyone with appropriate RBAC (Roles Based Access Control) permissions, can use Cost Analysis to track metered API consumption, as follows:
- Sign in to the Azure portal at https://portal.azure.com.
- Go to Cost Management + Billing > Cost Management > Cost analysis.
- For the filter near the top, select Service name: Microsoft Graph Servies.
- For the Group by dropdown menu near the right, select Meter.
This view offers a convenient way to observe API consumption per day over a period of time.
You can also use the pie charts near the bottom to further break down the costs for analysis, using the Resource and Meter filters.
For more details about cost management, see Cost Management + Billing documentation.
