The session daemon is responsible for managing tracing sessions and
what they logically contain (channel properties, enabled/disabled
-events, etc.). By communicating locally with instrumented applications
-(using LTTng-UST) and with the LTTng Linux kernel modules
+events, and the rest). By communicating locally with instrumented
+applications (using LTTng-UST) and with the LTTng Linux kernel modules
(LTTng-modules), it oversees all tracing activities.
One of the many things that `lttng-sessiond` does is to keep
so that they are initialized, enable/disable specific probes based on
enabled/disabled events by the user, send event filters information to
LTTng tracers so that filtering actually happens at the tracer site,
-start/stop tracing a specific application or the Linux kernel, etc.
+start/stop tracing a specific application or the Linux kernel, and more.
The session daemon is not useful without some user controlling it,
because it's only a sophisticated control interchange and thus
instances of `lttng-sessiond` may run simultaneously, each belonging
to a different user and each operating independently of the others.
Only `root`'s session daemon, however, may control LTTng kernel modules
-(i.e. the kernel tracer). With that in mind, if a user has no root
+(that is, the kernel tracer). With that in mind, if a user has no root
access on the target system, he cannot trace the system's kernel, but
should still be able to trace its own instrumented applications.
