Logging Level
For the GWT preview, the setting made in Preferences is the lowest level of logging available in preview. For example, if the logging level is set to INFO in the Preferences, you cannot change it to DEBUG in the preview pane.
The available log levels (GWT) are:
- FATAL
- ERROR
- WARN
- INFO (The default logging level)
- DEBUG
- TRACE
The verbosity (detail) of logging increases with the logging level in cumulative fashion. For example, the
WARN level also shows all
ERROR and
FATAL messages;
INFO also shows
WARN messages; and so on.
You can choose the logging level in the preview pane using
context.form.log or
context.form.logger. The
logger API is available in all the script contexts and it allows the user to log at all logging levels. For details of
log and
logger APIs, see
API for Scripting. The logging level specified applies only to that specific preview session. Messages logged by user scripts are shown in the
DEBUG log level.
You can change the default logging level used in the preview tabs in the user preferences, under .
At runtime, when GWT Forms are used, you can enable logging by using a URL parameter
log_level. You need to set the value of the
log_level parameter to any logging level. The specified log level is enabled in that case. For example, if you access
TIBCO Cloud BPM Work Manager as:
http://<server>:<port>/apps/work-manager?log_level=INFO
You see
INFO,
WARN,
ERROR, and
FATAL messages in the log viewer.
