Hello every boby!
I am a high school student and it is now about one month that i decided to
interest on lttng projet because i was searching about some metric tools for
unix systems.
The goal of my research is to develop a tool which would work as a "fligth
recover " for a unix system running on a power PC hardward support.
i decided to work for the first time on an intel processor and after, i will
make a croos compilation for my target which is a power PC processor
I have already built a linux kernel with the lttng patch and i have install all
the need tool to have a lttv analyser
Because i would like to trace some programm running on userspace, i have
install usttrace tool.
After this i wrote a short application with a marker inside as i see in the
usttrace tutorial available on website.
When i run this with command $usttrace ./testprogramm , i have in the promt the
name of directory where trace are logged and i can use lttv to analyze it. here
i can see well my event "myevent" on the wiever.
But when i activated kernel trace with command $ lttctl -C -w /tmp/trace1
trace1, and run my userspace programm with command $ ./testprogramm, i am
not able to get the myevent.
so that, i want to know how tu run lttctl tools and userspace programm to get
and analyze simultaneous on the lttv-gui ,kernel event and userspace event.
thank you all for your help.
Patrick
