INFO: informational messages that highlight the progress of the application (successful initialization, service or cluster start and stop, configuration assumptions, etc).
WARN: events that can potentially cause some problems in the application, such as exceptions, loss of connectivity, retrying some operations, etc. These events can be recovered and give hints to the users on potential subsequent errors.
ERROR: error events that prevent you to perform operations but might still allow the application to continue running (invalid syntax used in a processor, etc.). These errors are useful for users who want to intervene to investigate a problem, after a failure of a pipeline execution for example. For more information, see Using notifications and logs to debug a pipeline.
