Open edX Caliper Tracking can be used to transform the edX traditional event logs into Caliper Analytics Specifications provided by IMS Global. Generated logs can be consumed by any analytics application which is compatible with Caliper Standard.

To install openedx-caliper-tracking in your Open edX installation, please add the following line to your requirements file. (For most Open edX installations it should be located at edx-platform/requirements/edx/base.txt):

openedx-caliper-tracking==0.11.6

To enable and use openedx-caliper-tracking:

1. Add ENABLE_EVENT_CALIPERIZATION flag under FEATURES in the following files:

• /edx/app/edxapp/lms.env.json
• /edx/app/edxapp/cms.env.json

These files should be located at /edx/app/edxapp/ directory, see the example below:

"FEATURES": {
    ...

    "ENABLE_EVENT_CALIPERIZATION": true,

    ...
}

2. Add the following lines:

   if FEATURES.get('ENABLE_EVENT_CALIPERIZATION'):
       INSTALLED_APPS.insert(
           INSTALLED_APPS.index('eventtracking.django.apps.EventTrackingConfig'),
           'openedx_caliper_tracking'
       )
   

in the following files:

• lms/envs/aws.py (production.py for ironwood release)
• cms/envs/aws.py (production.py for ironwood release)

Transformed events are logged using 'logging.handlers.SysLogHandler' with 'facility: local2'.

We need to create output files manually and set appropriate permissions for syslog user. To do so, please follow the steps below:

1. Create a log file with read/write permissions given to syslog user e.g: /edx/var/log/caliper-analytics/caliper.log

2. Create a mapping for 'local2' in the configuration files present in /etc/rsyslog.d/

   local2.*                 /edx/var/log/caliper-analytics/caliper.log
   

Using the app, we can also send the transformed event logs to some third party broker API (e.g. kafka). To do this, we have to add the following configurations

Note: Set these settings only if you want to send the logs to some external consumer.

1. Add ENABLE_CALIPER_EVENTS_DELIVERY flag under FEATURES in the following files:

• /edx/app/edxapp/lms.env.json
• /edx/app/edxapp/cms.env.json

These files should be located at /edx/app/edxapp/ directory, see the example below:

"FEATURES": {
    ...

    "ENABLE_CALIPER_EVENTS_DELIVERY": true,

    ...
}

2. Add the key CALIPER_DELIVERY_ENDPOINT and its value in the lms.env.json and cms.env.json files.

3. Add the key CALIPER_DELIVERY_AUTH_TOKEN and its value in the lms.auth.json and cms.auth.json files.

4. Add the following lines:

   CALIPER_DELIVERY_ENDPOINT = ENV_TOKENS.get('CALIPER_DELIVERY_ENDPOINT')
   CALIPER_DELIVERY_AUTH_TOKEN = AUTH_TOKENS.get('CALIPER_DELIVERY_AUTH_TOKEN')
   

in the following files:

• lms/envs/aws.py (production.py for ironwood release)
• cms/envs/aws.py (production.py for ironwood release)
