NAME

6       lttng-crash - Recover and view LTTng 2 trace buffers in the event of a
7       crash
8

SYNOPSIS

10       lttng-crash [--extract=PATH | --viewer=VIEWER] [-v | -vv | -vvv]
11

DESCRIPTION

13       The Linux Trace Toolkit: next generation <https://lttng.org/> is an
14       open source software package used for correlated tracing of the Linux
15       kernel, user applications, and user libraries.
16
17       LTTng consists of Linux kernel modules (for Linux kernel tracing) and
18       dynamically loaded libraries (for user application and library
19       tracing).
20
21       The lttng-crash command-line tool is used to recover and view LTTng
22       trace buffers in the event of a system crash.
23

OPTIONS

25       -x PATH, --extract=PATH
26           Extract recovered traces to path PATH; do not execute the trace
27           viewer.
28
29       -v, --verbose
30           Increase verbosity.
31
32           Three levels of verbosity are available, which are triggered by
33           appending additional v letters to the option (that is, -vv and
34           -vvv).
35
36       -e VIEWER, --viewer=VIEWER
37           Use trace viewer VIEWER to view the trace buffers.  VIEWER is the
38           absolute path to the viewer command to use, and it can contain
39           command arguments as well. The trace directory paths are passed to
40           the VIEWER command as its last arguments.
41
42           Default: babeltrace.
