[Power BI] Cost Allocation of Shared Log Analytics Workspace

📝 Scenario

As a FinOps Practitioner i want to be able to take advantage of Log analytics commitment discounts as well as participate in Microsoft best practices for centralized log analytics. In order to do this i need to easily be able to showback and chargeback my log analytics costs to teams that are using this workspace. (Reference: https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/how-to-allocate-azure-monitor-logs-ingestion-costs-by-resource/ba-p/3813322)

💎 Solution

Using the workspace referenced in the scenario, We're able to understand how much each tag value is charged per day. Using the Cost Summary PowerBI i would like to be able to visualize the costs per tag in my FinOps Toolkit reports so that teams are aware of what they're spending in Log Analytics without having to go to the workbook.
