Not directly. You could probably work something out by parsing the output of babeltrace in "live" mode. Look at the --log-level option of the lttng enable-event command in the lttng(1) man page to only record events of certain log levels. Be aware that LTTng can drop events under heavy loads; make sure that is not a problem in your particular scenario. > 2) is there a way to stdout the logs of lttng.
