Log Viewer

Interactive log viewing and analysis for the Moodle development environment.

Ask the user which logs to view:

Use the AskUserQuestion tool to ask:

• Question: "Which logs would you like to view?"
• Options:
  1. Nginx access logs (all instances)
  2. Nginx error logs (all instances)
  3. PHP-FPM error logs (all pools)
  4. Moodle debug logs
  5. Docker container logs
  6. Database logs
  7. All recent errors (aggregated)

Then ask for details:

• Time range: Last 10 lines, 50 lines, 100 lines, or custom
• Filter pattern (optional): Search for specific errors or patterns
• Follow mode: Yes/No (tail -f)
