The Event Viewer displays thread and exception execution over time. To display the timing information it uses trace information generated by Cortex-M3, M4, M7, M23, and M33 devices and requires a suitable debug adapter.
Prerequisites for using the Event Viewer
In order to view the thread execution over time, configure the target as described in:
Using the Trace Configuration dialog of these adapters you should configure the following:
ULINKpro and ULINKplus allow you to display interrupts and exceptions. In this dialog, enable Trace Events - EXCTRC: Exception Tracing to see the exception execution over time.
ULINK2 and J-Link do not offer exception tracing due to limited SWO trace bandwidth.
Using Event Viewer
Open the window with Debug - OS Support - Event Viewer.
Load... imports the thread- and exception-switching history previously saved in a file (*.UVTSK). Data can be analyzed off-line.
Save... stores the thread- and exception-switching history in a file (*.UVTSK) for future analysis.

All Threads graph
The All Threads graph shows event-switching occurrences with a blue X.
Blue opening brackets < (left red circle in the picture) indicate event-switching occurrences that cannot be resolved on the graphical scale. You can zoom-in at those points to view detailed event switches.
The red opening bracket < (right red circle in the picture) indicates event-switching occurrences that cannot be resolved on the graphical and time scale. Zooming in at those points will not deliver details on the time scale. The events are shown as if occurred at the same time. This is due to lack of timing information. Select a smaller number for Timestamps Prescaler in Options for Target - Debug - Settings - Trace.
