LTTNG-CRASH(1)                LTTng Manual                LTTNG-CRASH(1)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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.
