[lttng-dev] Probleme with live session on LTTng 2.7.0

[BADEUIL Thierry]

And last answer, here is the exact error message :
tmxv3 at tmxv3-ThinkPad-T530:~$ sudo babeltrace -i lttng-live net://localhost/host/\(none\)/test -v

Please give us the output of the following when everything else is setup:

babeltrace -i lttng-live net://localhost

Base on this output you seem to be "opening" the "net://..." path? Not sure why.

Perfect regarding Babeltrace but I would recommend that you upgrade lttng to the latest stable (2.10).
