Thank you for any information.
Note that lttng-sessiond can be started with a specific group id for "control" purpose that allow only users of the group to control it. From there you could have a simple popen based custom application that run the cli client. There are multiple ways to achieve what you are looking for. We also expose an API/lib (liblttng-ctl) to talk to the sessiond [1]. The best documentation on how to use this API is the headers [1] and the command line client implementation [3].
