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 <http://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.
