Aggregated usage statistics (for training and translation) are visible to system administrators, and accessible through Administration > Usage statistics.
The displayed character counts are:
The source + target characters in all corpora in an engine (excluding stock corpora) for training
The source characters in translatable segments for translation
Only successfully finished training/translation jobs generate statistical entries. The month into which an entry gets logged to depends on the finishing date and time of the job, in UTC.
Statistics by month
The statistics dashboard shows all training and translation statistics up to now, with the current month highlighted.
By clicking on a month, you can access a detailed list of engines that were involved in either training or translation in the particular month.
Statistics by engine
If you are interested in which engines are used most, or in the usage history of a particular engine, go to the Engines tab. Here you will find the sum of characters trained and translated by all engines. By clicking on an engine, you can see the “activity” history of the particular engine over past months.
