The answers we come up with can be useful to others. The version you provided here is the version of lttng-tools installed on your system, which is not relevant to investigate your issue. What is needed here is the version of lttng-modules: the Linux kernel modules implementing the kernel tracing feature of LTTng. Those are different packages altogether. May I recommend that you install the package containing the "modinfo" tool on your system to query the lttng-modules version ? An alternative to query the lttng-modules version, if you really cannot install modinfo, would be: strings /lib/modules/$(uname -r)/extra/lttng-tracer.ko | grep "^version=" Thank you, Mathieu > Thank You > with regards > G Madhan Mohan > On Tue, Mar 15, 2022 at 9:19 PM Mathieu Desnoyers < [ > mailto:mathieu.desnoy...@efficios.com | mathieu.desnoy...@efficios.com ] > > wrote: >> ----- On Mar 15, 2022, at 2:48 AM, lttng-dev [ >> mailto:lttng-dev@lists.lttng.org >> | lttng-dev@lists.lttng.org ] wrote: >> > Dear Sir/Madam, >> > I am Madhan , working as an embedded engineer in 5GTB.
