class VizkitInfoViewer

Graphical user interface displaying information of a Utilrb::EventLoop such as queued tasks and worker threads executing the tasks. The key information is the task's time consumption. Completed tasks are no longer displayed.

Periodical timers are listed, as well. You even have basic interactive possibilities such as cancelling the timer and setting the period.

This GUI is intended to help developers debug their own GUIs or other applications with asynchronous components by identifying 'hanging' tasks like network communication etc.
