Description
In BBB during a visio or at the end of it, it presents a learning analytics dashboard with the time spent by each participant and its interaction in the visio (https://support.bigbluebutton.org/hc/en-us/articles/19304662953751-Learning-Analytics-Dashboard)
This dash board can be accessed on a specific URL of BBB so we could have a icon in the action column of the bbb conference listing to access this Learning Analytics Dashboard (LAD). Some one did it in an external interface as described here (https://support.bigbluebutton.org/hc/en-us/articles/19304662953751-Learning-Analytics-Dashboard)
Another option even more interesting in Chamilo y to download all the information presented in the LAD as a json file and insert all the data in Chamilo to include those information in Chamilo's report.
It is indicated on bigbluebutton/bigbluebutton#13997 :
If your a developer, you an also use bbb-events to extract out a JSON file that forms the underlying data for the Learning Analytics Dashboard after each session finishes, in case you want to send the data to an external database, for example.
