Logging options

Logging solutions allow you to display exchanges between components when a program executes.

Genero provides several build-in options to get debug information, as well as logging features:

Get the stack trace with base.Application.getStackTrace()
Display the GUI protocol exchange in stderr with FGLGUIDEBUG.
Display the SQL statements execution in stderr with FGLSQLDEBUG.
Display Web Services API calls in stderr with FGLWSDEBUG.
Produce function call stack trace, with fglrun --trace option.
Produce source code coverage info with fglrun --merge-cov / FGLCOV.
Log front-end protocol exchange with fglrun --start-guilog option.
Front-ends can add specific markers in the front-end protocol log with GUI log events.
Produce application log files in case of runtime error, with STARTLOG().

Important:

Sensitive and personal data may be written to the output. Make sure that the log output is written to files that can only be read by application administrators.
