Entity-based (per device, user, etc.) total license usage counts the total number of unique entity licenses used during the time period (one month). This differs from local CommCell usage and the License Summary report in that the entity-based total license usage includes entities that might have been deleted or deconfigured throughout the month.
For example, if within the month (in this example, a 30-day period) a Service Provider sees the following number of clients:
Number of Clients
A, B, C
In this example, the billed entity usage for the month is 4, despite the fact that no more than 3 licenses were used simultaneously at a given time. Per our licensing agreements, the billed usage is 4 because total usage is based on the highest count of unique entities (that is A,B, C, and D) used during the time period. The number of entities used simultaneously is not part of the total calculation. The same calculation applies for user-based licenses such as with SaaS protection (also O365, GSuite, and others).
