Statistics in OLAT are implemented in a pluggable way. This means that you can create additional kinds of statistics or exclude some of the existing ones if you so wish.
There are two areas which are pluggable:
GUI: There is now a new tool for a course called 'Statistics'. In there you can plug in additional statistics.
Updater: Each statistic plugin needs a way to update its table with data from new logging actions. This part is bundled into a updater.
