Analyzer capacity license is a consumption-based licensing model introduced in Qlik Sense February 2019 which allows a pool of user to consume apps by unit of time (unit is 6 minutes) without the need of having a license assigned to a user (named user).
When a user from the pool logs in the hub and opens an app he/she will consume 1 unit after 6 minutes and extra unit will be consumed thereafter in increments. For example: If the user stays in for 15 minutes, 3 units will be consumed (18 minutes) as a unit started is marked as a unit consumed. No consumption is registered if the user is logged in but idle (not opening apps, sheets,...).
When all analyzer units have been consumed, no users from the pool can access Qlik Sense, until the monthly reset occurs. To avoid lockout, coverage can be added to the subscription. Coverage is a function that allows to buy minutes packages automatically when consumed, it can either be unlimited or with a defined ceiling. For more information see Page 2 B.
