How open edx stores course content data in mongo database?

Question

I am working on online course ware website which is similar to open edx.

Course ware data is stored in mongo database, I want to find out amount of disk space taken by each course.

The database is edxapp which contains following collections: 1. modulestore 2. fs.files 3. fs.chunks

Recently, the Open edX modulestore was split into three sections.

use edxapp

To see the courses:

db.modulestore.active_versions.find().pretty()

To see the course structure which contains the course itself, sections, subsections, and units as blocks:

db.modulestore.structures.find().pretty()

Finally, to see the course definitions which contain the actual HTML content of the units:

db.modulestore.definitions.find().pretty()

In order to check the size of any of those collections, simply run:

db.<collection.name>.stats()

This will output the storageSize of the collection.
