NAME
----
lttng-crash - Recover and view LTTng 2 trace buffers in the event of a crash


SYNOPSIS
--------
[verse]
*lttng-crash* [option:--extract='PATH' | option:--viewer='VIEWER'] [option:-v | option:-vv | option:-vvv]


DESCRIPTION
-----------
The https://lttng.org/[_Linux Trace Toolkit: next generation_] 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.


OPTIONS
-------
option:-x 'PATH', option:--extract='PATH'::
    Extract recovered traces to path 'PATH'; do not execute the trace
    viewer.

option:-v, option:--verbose::
    Increase verbosity.
+
Three levels of verbosity are available, which are triggered by
appending additional `v` letters to the option
(that is, `-vv` and `-vvv`).

option:-e 'VIEWER', option:--viewer='VIEWER'::
    Use trace viewer 'VIEWER' to view the trace buffers. 'VIEWER' is the
    absolute path to the viewer command to use, and it can contain
    command arguments as well. The trace directory paths are passed to
    the 'VIEWER' command as its last arguments.
+
Default: `babeltrace`.
