Описание (Description)
The Linux Trace Toolkit: next generation <https://lttng.org/> is
an open source software package used for correlated tracing of
the Linux kernel, user applications, and user libraries.
LTTng consists of Linux kernel modules (for Linux kernel tracing)
and dynamically loaded libraries (for user application and
library tracing).
The lttng-crash
command-line tool is used to recover and view
LTTng trace buffers in the event of a system crash.
Параметры (Options)

Extract recovered traces to path PATH; do not execute the
trace viewer.

Three levels of verbosity are available, which are triggered
by appending additional v

Use trace viewer VIEWER to view the trace buffers. VIEWER is

are passed to the VIEWER command as its last arguments.
