Hi,
In order to trace the kernel, you need the LTTng kernel modules available in
the package "lttng-modules-dkms". So make sure you have these three packages
installed:
# sudo apt-get install lttng-tools lttng-modules-dkms babeltrace
The error message you got indicates that there is simply no LTTng modules
loaded. Please make sure they are loaded and if the problem persist, let us know!
Thanks!
David
