Parse the edX event log, convert the events to xAPI format, and publish them to an LRS.

$ git clone https://github.com/adlnet/edx-xapi-bridge.git
$ cd edx-xapi-bridge
$ virtualenv env
$ source env/bin/activate
(env)$ pip install -r requirements.txt
(env)$ deactivate
$ 

Rename the file xapi-bridge/settings-dist.py to settings.py and change the properties to match your environment. There are several properties you will want to customize, and they are documented below.

• PUBLISH_MAX_PAYLOAD and PUBLISH_MAX_WAIT_TIME

  To save bandwidth and server time, the xAPI Bridge will publish edX events in batches of variable size, depending on the configuration. It will wait to publish a batch until either PUBLISH_MAX_PAYLOAD number of events have accumulated, or PUBLISH_MAX_WAIT_TIME seconds have elapsed since the oldest event was queued for publishing. You should tune these values based on the expected usage of the edX LMS and the performance of the LRS.

  Reasonable default values are 10 and 60, respectively.

• LRS_ENDPOINT, LRS_USERNAME, and LRS_PASSWORD

  The URL and login credentials of the LRS to which you want to publish edX events. The endpoint URL should end in a slash, e.g. http://mydoma.in/xAPI/.

There is no process management yet, so just run the module directly:

$ source env/bin/activate
(env)$ python xapi-bridge [watchfile]
(env)$ deactivate
$

The program can optionally take one argument, which is the file path to the log to be watched. If omitted, it is assumed to be the default location in the edX Development Stack, /edx/var/log/tracking.log.

NOTE: The tracking log typically has very strict permissions on it, so make sure the user account running the xAPI-Bridge has permissions to read the log file.
