# tWarn

Triggers a warning often caught by the tLogCatcher component for exhaustive log.

Both tDie and tWarn components are closely related to the tLogCatcher component. They generally make sense when used alongside a tLogCatcher in order for the log data collected to be encapsulated and passed on to the output defined.

This component provides a priority-rated message to the next component. It does not stop your Job in case of error. If you want to kill a Job in case of error, see the tDie documentation.
