The only way I can see this working is by recreating the same session<br>
configuration (with the same output destination) and using lttng<br>
enable-channel's -C (tracefile-size) and -W (tracefile-count) options<br>
to define an upper bound on each trace's size.<br>
<br>
Is this what you are looking for?<br>
