Hello

some of the things you mention are possible, some others are not (or require new plugins to be tracked)

user login -> yes, this is tracked.
article creation / edition -> yes, this is tracked.
Jevents events added/edited -> no, we don't have a plugin for Jevents.
sobipro ->we have a plugin for sobipro, but maybe some things you need it to track need to be developed as well because are not available on the plugin as-is.

Ok I think it's better than no tracking at all.

I now got the component (Extended), some modules and plugins. I installed them all but where is the data displayed :-) ?

If I click the component in backend, there's no data displayed. When I click on GO nothing happens.
I installed these 4 modules, but only Content Statistics (EVOLUTION IN TIME) is shown in my module manager
mod_content_statistics_compare_1.5.0_2.5_admin.zip
mod_content_statistics_1.3.1_1.6_admin.zip
mod_content_statistics_individual_1.5.0_2.5_admin.zip
mod_content_statistics_individual_1.5.0_2.5.zip

How do I get Information displayed in the backend now?
How do I need to set up the component?

Hello there!

did you follow our installation instructions? http://www.joomlathat.com/documentation/content-statistics/installation

it looks like you installed all the modules.. but not the main thing, which are the plugins! have you installed and enabled them? is that the problem?

I installed and activated the following plugins:
Content Statistics - Users
Content Statistics - SOBI Pro
Content Statistics - Login (backend)
Content Statistics - JomSocial
Content Statistics - Joomla articles (content)

Do I miss any that are necessary?

I now see activities for community, content, login and sobipro in the comoponentview in my backend.
But I have only 1 module "Content Statistics (EVOLUTION IN TIME)" that I can display. I installed 4 alltogether but they arn't shown in the module manager :-(

they aren't?? did you install the front-end ones? or the admin ones?
