LTTNG-CRASH(1) LTTng Manual LTTNG-CRASH(1)
lttng-crash - Recover and view LTTng 2 trace buffers in the event of
a crash
lttng-crash [--extract=PATH | --viewer=VIEWER] [-v | -vv | -vvv]
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.
-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.
