Hi Yves,

We try to stick to English on this mailing list so the questions and
answers remain easily searchable.

The example in the docs uses "time" without importing it, I have sent
a Pull Request to address that.
However, addressing the problem you are encountering, where does
"hello-logger" come from?

Can you post the code and versions of the components you are using?

Thanks,
Jérémie

Hi, i my script i just change "my-logger" by "hello-logger" (hello.py  
in attachment).
I try to figure out the probem by
		export LTTNG_UST_PYTHON_DEBUG=1
and i found this:

You can see 'bad server command' and 'exception' in the last lines.

The bad server command makes me wonder if you are using the official
LTTng 2.7.0 release.

Are you sure you don't have a stale UST or tools installation from master?
Also, the lttng-sessiond logs in verbose mode (-vvv) would be useful here.

Hi Yves,

We are currently looking a little bit more into it. It might be an error 
in the documentation.

The example report the same error without the 'import lttngust'. If you 
use python 3 it seems to work.

This seems related to the logging.basicConfig() which provide as basic 
configuration for the root handler. See [1] for more info.

For now you can simply add the logging.basicConfig() before everything.
I'm not sure if this is a workaround or simply how logging in python 
works in general.

Cheers!

Hi,
Adding "logging.basicConfig()" seems to work well. "lttng list -u -a"  
return the list of all python log
BUT
after enabling all event trace (lttng enable-event -u -a)
the trace contain only  "lttng_ust_statedump" event, and not a single  
event from the script (warning,error... )
THKs!
Yves

Hi Yves,

You might want to enable all the python events via
'lttng enable-event -p -a'.

Cheers!

Hi,
i finaly found the solution of my problem
First in the exemple of the documentation  
(https://lttng.org/docs/#doc-python-application),
	we must add "logging.basicConfig()" to handle the log (or other handler)
As lttng UST python doesn't work when installing from ppa repository
download bash script (from http://paste.ubuntu.com/10816886/) and  
replace (line 18) by "./configure --enable-python-agent" for lttng-ust  
compilation
install and enjoy
THKS.

j'ai un souci avec lltngust pour les application python
Pour l'exemple de la Doc
	https://lttng.org/docs/#doc-python-application
j'ai l'erreur:
	No handlers could be found for logger "hello-logger"

la commande "lttng list -u -a" me retourne bien la liste des trace point:

	PID: 5228 - Name: python
       lttng_python:event (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)

(type: tracepoint)
       lttng_ust_statedump:start (loglevel: TRACE_DEBUG_LINE (13))  
(type: tracepoint)

Mais pas de resultats dans le repertoire des evenements lorsque  
j'active le tracage lttng.

Resumé
	Probleme 1 :No handlers could be found for logger
		je croyais que "import lttngust" devait gerer cette situation

	Probleme 2: pas de resultats au tracage
Merci.
