LTI Usage Plugin for Moodle

Overview

The LTI Usage plugin is a Moodle local plugin that provides administrators and managers with a comprehensive report on Learning Tools Interoperability (LTI) activities across the entire site. This plugin helps institutions track and manage their LTI tool usage effectively.

Features

LTI Activity Reporting

• Comprehensive Scanning: Scans all courses on the site to identify LTI activities
• Tool Type Organization: Groups LTI activities by tool type (pre-configured tools vs. manual/custom LTIs)
• Detailed Information: Displays course name, activity name, visibility status, and direct links to activities
• Real-time Data: Always shows current LTI usage across the site

Administrative Controls

• Delete Functionality: Site administrators can delete LTI activities directly from the report
• Access Control: Delete links are only visible to site administrators
• Confirmation Dialogs: Safe deletion with confirmation prompts

Installation

1. Download the plugin files
2. Extract to local directory in your Moodle installation
3. Visit Site Administration → Notifications to complete installation
4. Configure capabilities as needed

Configuration

Capabilities

• local/ltiusage:viewltiusage - View the LTI usage report (assigned to managers by default)
• local/ltiusage:manage - Manage plugin settings (assigned to managers by default)

Usage

Viewing LTI Usage

1. Access the plugin through:
   • Site Administration → Plugins → Local → LTI Usage
2. View organized tables of LTI activities by tool type
3. Use pagination controls to navigate through large datasets

Managing LTI Activities

• For Administrators: Delete links appear in the table for direct LTI activity removal
• For Managers: View-only access to monitor LTI usage across courses

Technical Details

Requirements

• Moodle 4.5 or later
• PHP 8.0 or higher
• Database access for LTI tables

Database Tables Accessed

• lti - LTI activity instances
• lti_types - Pre-configured LTI tool types
• course_modules - Course module information
• course - Course information

AJAX Implementation

The plugin uses Moodle's AMD (Asynchronous Module Definition) system for smooth pagination: - Prevents page refreshes during navigation - Maintains scroll position at table top - Handles multiple paginated tables independently - Provides loading feedback during AJAX requests

Security Considerations

• Capability Checks: All access is controlled through Moodle capabilities
• Context Validation: Operations require appropriate system context
• Input Sanitization: All user inputs are properly sanitized
• Admin-only Actions: Delete functionality restricted to site administrators

Troubleshooting

Common Issues

Pagination Not Working - Check browser console for JavaScript errors - Ensure AMD modules are properly built - Verify AJAX requests are not blocked

Delete Links Not Showing - Confirm user is a site administrator - Check capability assignments - Verify Moodle version compatibility

Plugin Not Appearing in Navigation - Clear Moodle caches - Check navigation settings - Verify plugin installation completed successfully
