Is there an activity and active user log available?

Steps to reproduce
1. No steps necessary
2.
3.

Expected behaviour
Have a global activity and active user log.

Actual behaviour
As fas as I know there's only the Activity app that shows all activity for my account not all activity by all users and log all active sessions.

Server configuration
Operating system: CentOS 6.8
Web server: Apache 2.2
Database: MySQL
PHP version: 5.4
ownCloud version (see ownCloud admin page): 9.1.1

Moved to the feature requests category as no such global activity for all users is included in oC.

Thanks, it will be highly usable for admins to keep track of things.
