Figure 2:3. Vitesse Log Window
In the upper list box, there is a log of:
-
Scripts started
-
Triggers executed
-
Vitesse functions called, with their name, input parameters, return values and any exceptions.
-
When reload is performed
In the lower list box, only exceptions are listed.
-
To position yourself in the top list on the function call that caused the exception, double click the exception in the lower list box.
This can be useful to find exceptions raised during lengthy executions.
There are also buttons to clear the contents of the log window and to close the window.
See also Vitesse Options for logging options.
It is also possible to issue debug messages from a Vitesse script which will be displayed in the log window. This can be done by using the kcs_ui.message_debug() function.
