The events dataset contains one row for each event in a main ping. This dataset is derived from main_summary so any of main_summary's filters affect this dataset as well.

Data is currently available from 2017-01-05 on.


The events dataset is updated daily, shortly after main_summary is updated. The job is scheduled on Airflow. The DAG is here.

Firefox events

Firefox has an API to record events, which are then submitted through the main ping. The format and mechanism of event collection in Firefox is documented here.
