Tracking Logs

This chapter provides reference information about the event data that is
delivered in data packages. Events are emitted by the server or the browser to
capture information about interactions with the courseware and the Instructor
Dashboard in the LMS, and are stored in JSON documents. In the data package,
event data is delivered in a log file.

The sections in this chapter describe:

* A :ref:`sample_events`.
* :ref:`common` that are included in the JSON document of every event.
* :ref:`Student_Event_Types` for interactions with the LMS outside of the
  Instructor Dashboard. 
* :ref:`Instructor_Event_Types` for interactions with the Instructor Dashboard
  in the LMS.

Student and instructor events are grouped into categories in this chapter. For
an alphabetical list of events, see the :ref:`event_list`.


.. _sample_events:

*************************
Sample Event
*************************

A sample event from an edX.log file follows. The JSON documents that include
event data are delivered in a compact, machine-readable format that can be
difficult to read at a glance.

This section describes the JSON fields that are common to the schema definitions
of all events.

=====================

**Type:** string

**Details:** Browser agent string of the user who triggered the event. 

.. _context:

===================

identify:

* The ``course_id`` of the course that generated the event.
* The ``org_id`` of the organization that lists the course. 
* The ``user_id`` of the individual who is performing the action. 
  
When included, ``course_user_tags`` contains a dictionary with the key(s) and
value(s) from the ``user_api_usercoursetag`` table for the user. See
:ref:`user_api_usercoursetag`.

The member fields are blank if values cannot be determined. The ``context``
field can also contain additional member fields that apply to specific events
only: see the description for each type of event.

.. _Student_Event_Types:

****************************************
Student Events
****************************************

This section lists the events that are logged for interactions with the LMS
outside the Instructor Dashboard.

* :ref:`enrollment`

* :ref:`navigational`

* :ref:`video`

* :ref:`pdf`

* :ref:`problem`

* :ref:`ora`

* :ref:`AB_Event_Types`

* :ref:`forum_events`

The descriptions that follow include what each event represents, the system
component it originates from, the history of any changes made to the event over
time, and any additional member fields that the ``context`` and ``event`` fields contain.

The value in the ``event_source`` field (see the :ref:`common` section above)
distinguishes between events that originate in the browser (in JavaScript) and
events that originate on the server (during the processing of a request).

.. _enrollment:

=========================
Enrollment Events
=========================

.. tracked_command.py

``edx.course.enrollment.activated`` and ``edx.course.enrollment.deactivated``
------------------------------------------------------------------------------

The server emits these events in response to course enrollment
activities completed by a student.

* When a student enrolls in a course, ``edx.course.enrollment.activated`` is
  emitted. On edx.org, this is typically the result of a student clicking
  **Register** for the course.

* When a student unenrolls from a course, ``edx.course.enrollment.deactivated``
  is emitted. On edx.org, this is typically the result of a student clicking
  **Unregister** for the course.

In addition, actions by instructors and course staff members also generate
enrollment events. For the actions that members of the course team complete that
result in these events, see :ref:`instructor_enrollment`.

**Event Source**: Server

**History**: These enrollment events were added on 03 Dec 2013.

       the :ref:`context`.
   * - ``user_id``
     - integer
     - Identifies the user who was enrolled or unenrolled.

   * - ``session``

     - The Django session ID, if available. Can be used to identify events for a
       specific user within a session. **History**: Added 07 May 2014.

.. _AB_Event_Types:

==========================
A/B Testing Events
==========================

Course authors can configure course content to present modules that contain
other modules. For example, a parent module can include two child modules with
content that differs in some way for comparison testing. When a student
navigates to a module that is set up for A/B testing in this way, the student is
randomly assigned to a group and shown only one of the child modules.

* Internally, a *partition* defines the type of experiment: comparing the
  effectiveness of video alone to text alone, for example. A course can include
  any number of modules with the same partition, or experiment type.

* For each partition, students are randomly assigned to a *group*. The group
  determines which content, either video or text in this example, is shown by
  every module with that partitioning.

The events that follow apply to modules that are set up to randomly assign
students to groups so that different content can be shown to the different
groups.

**History**: These events were added on 12 Mar 2014.

``assigned_user_to_partition``
----------------------------------

When a student views a module that is set up to test different child modules,
the server checks the ``user_api_usercoursetag`` table for the student's
assignment to the relevant partition, and to a group for that partition. 

* The partition ID is the ``user_api_usercoursetag.key``.

* The group ID is the ``user_api_usercoursetag.value``.

If the student does not yet have an assignment, the server emits an
``assigned_user_to_partition`` event and adds a row to the
``user_api_usercoursetag`` table for the student. See
:ref:`user_api_usercoursetag`.

.. note:: After this event is emitted, the common ``context`` field in all subsequent events includes a ``course_user_tags`` member field with the student's assigned partition and group.

``child_render``

the child module that was shown to the student.

.. _instructor_enrollment:

=============================
Instructor Enrollment Events
=============================

In addition to the enrollment events that are generated when students 
enroll in or unenroll from a course, actions by instructors and course staff
members also generate enrollment events.

* When a course author creates a course, his or her user account is enrolled in
  the course and the server emits an ``edx.course.enrollment.activated`` event.

* When a user with the Instructor or Course Staff role enrolls in a course, the
  server emits ``edx.course.enrollment.activated``. The server emits
  ``edx.course.enrollment.deactivated`` events when these users unenroll from a
  course.

* When a user with the Instructor or Course Staff role uses the **Batch
  Enrollment** feature to enroll students or other staff members in a course,
  the server emits an ``edx.course.enrollment.activated`` event for each
  enrollment. When this feature is used to unenroll students from a course, the
  server emits a ``edx.course.enrollment.deactivated`` for each unenrollment.

For details about the enrollment events, see :ref:`enrollment`.
