Problem statement
Is there a way to retrieve the number of registered standard database users per tenant?
Solution
Under the usage reports one can view the number of monthly active users per tenant. These are divided into connection types:
To find this go to Reports > Usage in Support Center. The total number of users for password connections is shown per tenant. Keep in mind, however, that these are for all password users, including custom database users. Also, these are monthly active users rather than all registered users.
There is no way to only show the number of registered users across standard database connections per tenant. This would need to be retrieved using either the User Import / Export extension or the Management API.
