NAME
lttng-crash - Recover and view LTTng 2 trace buffers in the event
of a crash
SYNOPSIS
lttng-crash [--extract=PATH | --viewer=VIEWER] [-v | -vv | -vvv]
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.
OPTIONS
-x PATH, --extract=PATH
Extract recovered traces to path PATH; do not execute the
trace viewer.
-v, --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).
-e VIEWER, --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.
Program information
-h, --help
Show help.
-V, --version
Show version.
