 In cluster billing mode, the combined 2 TB of Log Analytics usage adds the extra 1 TB of unused usage and is billed to the cluster resource. The Commitment tier detail shows the price equals to 3 TB multiplied by the Log Analytics effective per GB (per day) price of the Commitment tier. The price is also expressed as 0.6 units of the commitment tier per day rate. Workspace C is the Microsoft Sentinel enabled workspace that ingested 2 TB of data. Its commitment tier detail shows the price equals 2 TB multiplied by the Microsoft Sentinel effective per GB (per day) price of the Commitment tier. The price is also expressed as 0.4 units of the commitment tier per day rate.
