Platform Plugin Aspects

Purpose
This repository holds various Aspects plugins for the Open edX platform.

Sinks
Sinks are components that listen for events and store them in ClickHouse. The
events are emitted by the Open edX platform via Open edX events or Django signals.

Available Sinks

CourseOverviewSink - Listens for the COURSE_PUBLISHED event and stores the
course structure data through XBlockSink in ClickHouse.
ExternalIdSink - Listens for the post_save Django signal on the ExternalId
model and stores the external id data in ClickHouse.
UserProfile - Listens for the post_save Django signal on the UserProfile
model and stores the user profile data in ClickHouse.
UserRetirementSink - Listen for the USER_RETIRE_LMS_MISC Django signal and
remove the user PII information from ClickHouse.
CourseEnrollmentSink - Listen for the ENROLL_STATUS_CHANGE event and stores
the course enrollment data.

Commands
In addition to being an event listener, this package provides the following commands:

dump_data_to_clickhouse - This command allows bulk export of the data from the Sinks.
Allows bootstrapping a new data platform or backfilling lost or missing data.

python manage.py cms dump_data_to_clickhouse

load_test_tracking_events - This command allows loading test tracking events into
ClickHouse. This is useful for testing the ClickHouse connection to measure the performance of the
different data pipelines such as Vector, Event Bus (Redis and Kafka), and Celery.
Do not use this command in production as it will generate a large amount of data
and will slow down the system.

python manage.py cms load_test_tracking_events

monitor_load_test_tracking - Monitors the load test tracking script and saves
output for later analysis.

python manage.py cms monitor_load_test_tracking

Instructor Dashboard Integration
Dashboards from Aspects are integrated into the Instructor Dashboard via Superset Embedded SDK.
See Configuration for more details.

Getting Started with Development
Please see the Open edX documentation for guidance on Python development in this repo.

Deploying
The Platform Plugin Aspects component is a django plugin which doesn’t
need independent deployment. Therefore, its setup is reasonably straightforward.
First, it needs to be added to your service requirements, and then it will be
installed alongside requirements of the service.

Configuration

Instructor Dashboard Configuration
The Instructor Dashboard integration uses the Open edX Filters. To learn more about
the filters, see the Open edX Filters documentation. Make sure to configure the
superset pipeline into the filter as follows:

OPEN_EDX_FILTERS_CONFIG = {
"org.openedx.learning.instructor.dashboard.render.started.v1": {
"fail_silently": False,
"pipeline": [
"platform_plugin_superset.extensions.filters.AddSupersetTab",
]
},
}

SUPERSET_CONFIG - This setting is used to configure the Superset Embedded SDK.
The configuration is a dictionary that contains the following keys:

internal_service_url - The URL of the Superset instance (useful in development, omit in production).
service_url - The URL of the Superset instance.
username - The username of the Superset user.
password - The password of the Superset user.

ASPECTS_INSTRUCTOR_DASHBOARDS - This setting is used to configure the dashboards
that will be displayed in the Instructor Dashboard. The configuration is a list of
dictionaries that contains the following keys:

name - The name of the dashboard.
slug - The slug of the dashboard.
uuid - The UUID of the dashboard.
allow_translations - A boolean value that determines if the dashboard
is translated in Aspects.

SUPERSET_EXTRA_FILTERS_FORMAT - This setting is used to configure the extra filters
that will be applied to the dashboards. The configuration is a list of strings that
can be formatted with the following variables:

user - The user object.
course - The course object.

SUPERSET_DASHBOARD_LOCALES - This setting is used to configure the available locales
for the dashboards. The configuration is a list of supported locales by Aspects.

Event Sink Configuration

EVENT_SINK_CLICKHOUSE_BACKEND_CONFIG - This setting is used to configure the ClickHouse
connection. The configuration is a dictionary that contains the following keys:

url - The host of the ClickHouse instance.
database - The database name.
username - The username of the ClickHouse user.
password - The password of the ClickHouse user.
timeout_secs - The timeout in seconds for the ClickHouse connection.

EVENT_SINK_CLICKHOUSE_PII_MODELS - This setting is used to configure the models that
contain PII information. The configuration is a list of strings that contain the
table names where the PII information is stored.
EVENT_SINK_CLICKHOUSE_MODEL_CONFIG - This setting is used to provide compatibility
with multiple Open edX models. The configuration is a dictionary that contains the
following a key per model that contains a dictionary with the following keys:

module - The module path of the model.
model - The model class name.

Event Sinks are disabled by default. To enable them, you need to enable the following
waffle flag: event_sink_clickhouse.{{model_name}}.enabled where model name is the name
of the model that you want to enable. Or, you can enable them via settings by setting
EVENT_SINK_CLICKHOUSE_{{model_name}}_ENABLED to True.
