The Event Viewer is a graphical interface showing tasks and task-switching events on a time scale. Task names and IDs are displayed on the left side of the window. The time scale is displayed on the bottom border of the window.
Open the window with the menu Debug - OS Support - Event Viewer.
Load... imports the tasks and task-switching history previously saved in a file (*.UVTSK). Data can be analyzed off-line.
Save... stores the tasks and task-switching history in a file (*.UVTSK) for future analysis.
The time fields show:
Zoom buttons change the time scale:
Code Show opens the disassembly or source code window at the code line that caused the task transition.
Trace Show opens the windows Trace Data and the Trace Navigation. The data get synchronized between the windows.
Update Screen buttons control the screen output.
Transition buttons snap the reference line to the next transition point. Highlight a task name and click:
