Learning Management System Log Analysis Toolkit

Create an advanced Bash toolkit for analyzing LMS server logs, focusing on performance metrics, user engagement, and potential security incidents. The script should parse complex log files from popular LMS platforms like Moodle or Canvas, extract key metrics such as concurrent user sessions, course access patterns, and potential unauthorized access attempts. Implement real-time monitoring capabilities, generate daily/weekly reports, and create alert mechanisms for suspicious activities. Include functionality to compress and archive historical log data efficiently.
