Independent Study Spring 2019/Logging

Abstract

This independent study, Support for logging & data-mining peer-assessment behavior in Spring 2019, is about logging, which is convenient for the administrator or instructor to gather valuable usage of Expertiza from students and do some studies. This study can be divided into 2 parts, refactor of views/versions page and setup of ELK Stack.

views/versions

The previous version of views/versions page doesn't work well, so we need some refactoring to make it better.

• Before

• After

What needs to be done?

• current UI needs to record the username.
• All fields of event records need to have info buttons describing what they do.
• Search form needs to be changed.
• More models need to be tracked by PaperTrail.
• The order of log attributes needs to be changed.
• We need to add a column for the title (assignment name, course name, rubric name, etc.)
• User ID should be the username of the user, not the user’s row number in the users table.
• Figure out a way to show data in local timezone, but the time stored in database is in UTC by default.
