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 <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.
-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.
