Hi~ I wrote a Babeltrace Plugin myself, it's sink component class. It mainly obtains the readable log data of lttng from babeltrace, and I wrap the data into a format that I customize,then prints it out (I print the data into the socket, and send the data to other hosts through the socket). And I would like to ask what Open Source License does this plugin need to follow? Looking forward to your reply! thanks, Yuhua
