Dear Lttng community. I tried to profile the example code, as described in the documentation @ https://lttng.org/docs/v2.10 and I could not get any satisfactory result.
I am using - lttng (LTTng Trace Control) 2.10.2 - KeKriek - Ubuntu 18.04.2 I created the files hello-tp.c hello-tp.h hello.c as described in the documentation The code succesfully compiles. Kernel modules are loaded. lttng-sessiond --daemonize runs with not acknowledgement. nevertheless, lttng create session command returns an error I am unable to justify: lttng create test Session test created. Traces will be written in /home/luis/lttng-traces/test-20190416-173219 Error: Unable to create config file Error: Command error - Do I need any extra setup step that is no documented in the web? - Is the package at ubuntu repos working correctly? - are there known conflicts with any other software? cheers. Luis Ayuso
