Event Tracer


Event Tracer

The Event Tracer monitors and visualizes events occuring in the UBIK® system environment immediately, while the event data is also written by the logging mechanism in the background. This enables the user to watch events as they happen without the need to open log files. These events can be errors and warnings as well as messages generated out of the customizing code for debugging purposes (see logging category types).

Logging list

The list shows all events that occured since the start of the Studio session. Every entry has an information header shown in the list, consisting of the type and the time it occured as well as the time that elapsed, which is updated frequently. Every entry then can be expanded to show the full information included in this event.

Message Types

UBIK® Event Tracer is able to show the following event types:

Icon Type Content
IC EventTracer Error.png Error events the user should pay high attention to because the system is in a vulnerable state (marked with red error symbol); if the error message also provides a stack trace, the stacktrace will be shown on the right of the list box
IC EventTracer Warning.png Warning events that have to be investigated because they are potentially important to the productive use of the system (marked with yellow warning symbol)
IC EventTracer Message.png Message events that support the user in debugging or finding problems in general (marked with blue message symbol)
