From the uname -a output I can see that you are running a PREEMPT RT Linux kernel as you probably know because your hostname is realtimepi.

When you are running a kernel that was not packaged by your distribution you can't simply install the lttng-modules kernel modules as the Linux kernel header files installed on your machine would not match the ones expected by the modules package.

To use the lttng-modules, you will need to compile them from source. Have a look at the documentation on that subject: https://lttng.org/docs/v2.10/#doc-building-from-source. In your case, i believe you only need to build the modules from source.

Make sure you uninstall the lttng-modules-dkms package and then restart the lttng-sessiond process before trying again.

Install lttng-tools

If you have the LTTng‑tools Git source, run:.
If you have the LTTng‑tools Git source, run: $ ./bootstrap This script creates the configure script.
Configure the build: $ ./configure If you want the liblttng‑ctl Python bindings, use the ‑‑enable‑python‑bindings option. See also the PYTHON and PYTHON_CONFIG environment variables in ./configure ‑‑help. If you don’t want to build the manual pages, use the ‑‑disable‑man‑pages option. If you want to embed the manual pages into the lttng, lttng‑sessiond, lttng‑relayd, and lttng‑crash programs so that you don’t need man to view them, use the ‑‑enable‑embedded‑help option. If your Linux kernel is older than 2.6.27, use the ‑‑disable‑epoll option. This build configuration script finds LTTng‑UST with pkg‑config: set the PKG_CONFIG_PATH environment variable accordingly if pkg‑config cannot find the lttng‑ust package information. See ./configure ‑‑help for the complete list of options.
Build the project: $ make
Install the project: $ sudo make install $ sudo ldconfig
