What is the recommended approach to have an external process notified that a trace session rotation has completed on the lttng-relayd end?
I'm trying out the trace rotation functionality available in 2.11 (pre-release) and will be running a trace session inside a Linux container (userspace tracepoints only), and running lttng-relayd on the container host. I would then like to have a third process, a "collector"-like process, that will also be running on the container host and will have the responsibility of collecting completeted trace chunks (i.e. rotated chunks) and push them further along into a trace analysis pipeline. So far I've looked at using inotify to watch the lttng-traces/ directory, and the idea would be to infer a trace rotation based on that the destination directories post rotation are named on the format "%Y%m%dT%H%M%S%z-%Y%m%dT%H%M%S%z-<seqno>". But I'm not entirely satisifed with that approach. Ideally I would be able to be notified more explicitly that a rotation completed. Any thoughts and recommendations are most welcome.
