how can I define a "tracing"group , so I no longer need the sudo command?
$ sudo addgroup --system tracing
$ sudo adduser username tracing

You must log off and back on for group membership to be activated.

You may also want to add lttng-sessiond as a service:

$ sudo ln --symbolic /lib/init/upstart-job /etc/init.d/lttng-sessiond

And create /etc/init/lttng-sessiond.conf containing:

description "LTTng central tracing registry session daemon"
author "Stéphane Graber <[email protected]>"
start on local-filesystems
stop on runlevel [06]
respawn
exec lttng-sessiond

You can then start the session daemon with 'sudo service lttng-sessiond start' 
(stop it with 'stop', restart with 'restart').
Thanks, now it works
but when i
$ lttng create
$ lttng enable-event -k -a
$ lttng start
so, the function does not return!
only 'strg c' terminated the fuktion.

the same by
$ lttng stop
and
$ lttng destroy

but
$ lttng create
$ lttng enable-event -u -a
$ lttng start
$ lttng stop
$ lttng destroy
-> works

how can i remove all installed lttng_modules,
so that I can start again from the beginning?

Thanks
Klaus
sorry, i am a linux beginner
