To perform kernel tracing, lttng-sessiond daemon MUST be run as root since it must load kernel modules. Now to interact with and control a kernel tracing session one must be part of the "tracing" group or be root. > if it is can u let me know how to become tracing group member. Again, from the doc [1]: "The default tracing group name is *tracing*; you can set it to something else with the --group option when you start the root session daemon." [1] https://lttng.org/docs/v2.10/#doc-start-sessiond At this point you can google: how to create group on linux? how to add user to a group on linux? Cheers. -- Jonathan Rajotte-Julien EfficiOS
