Hello,
now its work!
i have download the new lttng-tools. (git pull)
the next problem:
with
sudo insmod
/lib/modules/3.8.0-29-generic/extra/addons/lttng-trace-events-sample.ko
and
lttng list -k
hurray! i see the new event!
now i start a lttng session and load the trace-events-sample.ko
(compiling the sample in the linux source code)
but i see not the event in the session. (looking in the eclipse viewer)
what i am doing wrong?
Regards,
Klaus

Aha! There is one crucial mistake in the ibm.com document: he
installs the packages in the wrong order. lttng-tools must be installed
AFTER lttng-modules and lttng-ust. lttng-modules can be installed before,
during or after lttng-ust, but userspace-rcu must be installed before
lttng-ust.
The problem is that the configure of lttng-tools detects the
presence or absence of lttng-modules and also detects the presence or
absence of lttng-ust, and adjusts to both. By installing lttng-tools before
lttng-modules, you've built an lttng-tools set that CANNOT be used to trace
the kernel.
So, try again from scratch, making sure to install lttng-tools last.
lttng-tools checks for kernel modules at run time, not at configure time.
You can safely install lttng-modules after lttng-tools and still use kernel
tracing.
Regards,
Jérémie
Dang, you're right. The build of lttng-tools reacts to the presence
or absence of lttng-ust, but is indifferent to the presence or absence of
lttng-modules. (Only liblttng-ctl.a is different, probably some internal
timestamps or some such)

Let's try to identify the module responsible. First, make sure
lttng-sessiond is NOT running. Then, do this in one shell:
$ sudo -H lttng-sessiond -vvv
It should fail after loading one of the modules.
You can also try:
$ sudo -H lttng-sessiond -vvv --no-kernel
In which case you should be able to do any lttng command except those
involving the kernel. For example, 'lttng list -u'.
here the output:
klaus@ubuntu:~$ sudo -H lttng-sessiond -vvv

Terminal 1 hangs now !!
in other terminal now no lttng call are work!
I can't reproduce this on a fresh Ubuntu 12.04 Server 64-bit install.
Are you sure you don't have files from prior versions of LTTng already
installed or that you are not skipping steps from the IBM guide?
The guide shows how to add your user to the "tracing" group. This
makes it unnecessary to invoke lttng as root. In your case, only the
session daemon needs to be started as root.
Jérémie
when i repeat the comand in other terminal:
