Hmmmm this is weird because usually you would have "lttng-traces/<session-name>-<date>-<time>/...." so something is not working right.
Can you open a bug report on bugs.lttng.org and provide the "lttng -vvv" logs and "lttng-sessiond -vvv" logs also ? Thanks! David Amit Margalit: > Indeed the path is _not_ different.
