Hi Wolfgang,

On session creation you can use -o to specify an output PATH.

Okai so just to be sure I tested the demo and everything work as 
expected let's see what is missing on your side.
Did you build from source or you got binary from a package manager ?

What do you mean by talk to it?

Looks fine so far.

Are you sure you got nothing ? Try lttng view if you have babeltrace 
installed.
Also did you start the daemon in verbose mode ? Otherwise it is expected 
to have no output.

Any particuliar reason to do an export LD_LIBRARY_PATH?

> row@cobra7:~/lttng_source/lttng-ust/doc/examples/demo$ ./demo-trace

If you want to have more time to test you might want to add a sleep() 
into the for loop in demo.c and put a higher loop threshold.
You will be able to test lttng list -u. Even if it looks like the events 
got registered, it is a good start to pinpoint the problem.
Also you can start the sessiond with -vvv for a more verbose mode as you 
probably know it.

Hi Jonathan,
 
as I'm struggling with the Internet style response I'll recap it here
 
> On session creation you can use -o to specify an output PATH.
Have tried to redirect to /tmp but no output there as well
 
> Did you build from source or you got binary from a package manager ?
yes, via git clone etc.
 
> What do you mean by talk to it?
I see daemon logs in response to the lttng commands. The exception is
that there is no reaction for the demo-trace run.
 
> Any particuliar reason to do an export LD_LIBRARY_PATH?
Ok, is no longer needed.
 
I've added the sleep but provider output is still like in my original post.
 
Below the steps I run again. Is it possible to get more info from the
demo-trace provider? Is the marked line ok?
 
thanks
Wolfgang R.

I see that UST debug tells us this:

"libust[5389/5391]: Info: sessiond not accepting connections to local apps
socket (in ust_listener_thread() at lttng-ust-comm.c:1221)"

and also for global apps socket.

So it means UST cannot talk to the session daemon.

Are you UST and sessiond versions compatible ? The output of
lttng-sessiond -vvv should help us understand why UST cannot
connect to it.

Thanks,

Mathieu

It looks like the UST application cannot talk to the session daemon
over the communication unix socket at all.

Normally, there would be activity in the session daemon when the

Please double-check that the ust and tools versions used are

Just right before the weekend I could repair it.
Seems that I had some trouble with the installed packages.

Here the steps working for me on Ubuntu 14 LTS

http://installion.co.uk/ubuntu/utopic/universe/l/lttng-tools/uninstall/index.html
sudo apt-get remove --auto-remove lttng-tools

https://launchpad.net/~lttng/+archive/ubuntu/ppa
sudo apt-add-repository ppa:lttng/ppa
sudo apt-get update
sudo apt-get install lttng-tools lttng-modules-dkms babeltrace liblttng-ust-dev python3-babeltrace

thanks for your investigations
Wolfgang R.

Alexandre, maintainer of the PPA packages, will be
back from vacation in 2 weeks.

Perhaps he could look into why you had to explicitly
uninstall packages before installing the PPA then.
Normally "conflicts with" should be taking care
of this kind of dependency.

Thanks,

Mathieu

Hi Mathieu,

weeks ago I did a different approach installing packages.
That one I can't recap.

Today I tried this one and simply started to get rid of existing things.

I would see this as a beginners confusion and not worth
to spend time here.

I'm quite happy to see the nice LTTng output ;)

Wolfgang R.

What I suspect happened here is that you installed some of the packages 
from source using "make install", which copies the libraries in 
/usr/local/lib/* .

*Then* you installed the packaged versions, which go in /usr/lib/*. But 
the tricky part is that on Ubuntu and many other (most?) distros, the 
ld.so.conf is configured to look in /usr/local/lib first for shared 
libraries. If it finds a useable one, it loads that one and stops there.

In such a case, /usr/bin/lttng, installed from packages, would end up 
using /usr/local/lib/liblttng-ust*.so, and so on. If both are not of the 
exact same version, it can cause obscure problems like the one you had.


This is a very common source of problems in fact. I don't know of any 
easy fix unfortunately, short of teaching people about library mangement 
;) or bumping the soname of lttng-tools and UST's shared libraries every 
release, to make sure non-compatible libraries are not loaded.

Cheers,
Alexandre

thanks Alexandre for investigating and it seems the way I did it

At least when I start working on the sources I should have better
tracked what make install is going to do.
