Description

Cairn, the analytics tool for Open edX, provides a comprehensive platform to assess the performance of your online courses. By collecting, storing, and exposing crucial data, Cairn simplifies the analytics process, offering a user-centric experience to educators, administrators, and learners alike.

Cairn Analytics Plugin is your go-to solution for gaining insights into online course performance. From efficient data collection using Vector to real-time visibility through Clickhouse and Superset, Cairn unlocks unparalleled analytics capabilities for you.

Designed with you in mind, Cairn Analytics Plugin is ideal for educators, administrators, and learners like you who seek in-depth analytics on Open edX courses. Unlock a unified platform for effortless data exploration.

How Does Cairn Analytics Plugin Work?

Cairn works in a simple way, following the collect/store/expose approach. Here’s how:

  1. Collection: Vector, a powerful log collector, efficiently gathers tracking logs on the server side
  2. Storage: The collected tracking log events find their home in a Clickhouse table, a fundamental component of Cairn. Clickhouse not only stores tracking logs but also exposes MySQL data through live and materialized views. This unique feature enables integration of event and MySQL data.
  3. Exposure: The data stored in Clickhouse becomes visible to end-users through an Apache Superset frontend. In other words, Cairn makes it easier for you to access and explore your data.
