| 5 | NAME | |
| 6 | ---- | |
| 7 | lttng-crash - Recover and view LTTng 2 trace buffers in the event of a crash | |
| 8 | ||
| 9 | ||
| 10 | SYNOPSIS | |
| 11 | -------- | |
| 12 | [verse] | |
| 13 | *lttng-crash* [option:--extract='PATH' | option:--viewer='VIEWER'] [option:-v | option:-vv | option:-vvv] | |
| 14 | ||
| 15 | ||
| 16 | DESCRIPTION | |
| 17 | ----------- | |
| 18 | The http://lttng.org/[_Linux Trace Toolkit: next generation_] is an open | |
| 19 | source software package used for correlated tracing of the Linux kernel, | |
| 20 | user applications, and user libraries. | |
| 21 | ||
| 22 | LTTng consists of Linux kernel modules (for Linux kernel tracing) and | |
| 23 | dynamically loaded libraries (for user application and library tracing). | |
| 24 | ||
| 25 | The _`lttng-crash`_ command-line tool is used to recover and view | |
| 26 | LTTng trace buffers in the event of a system crash. | |
| 27 | ||
| 28 | ||
| 29 | OPTIONS | |
| 30 | ------- | |
| 31 | option:-x, option:--extract='PATH':: | |
| 32 | Extract recovered traces to path 'PATH'; do not execute the trace | |
| 33 | viewer. | |
| 34 | ||
| 35 | option:-v, option:--verbose:: | |
| 36 | Increase verbosity. | |
| 37 | + | |
| 38 | Three levels of verbosity are available, which are triggered by | |
| 39 | appending additional `v` letters to the option | |
| 40 | (that is, `-vv` and `-vvv`). | |
| 41 | ||
| 42 | option:-e, option:--viewer='VIEWER':: | |
| 43 | Use trace viewer 'VIEWER' to view the trace buffers. 'VIEWER' is the | |
| 44 | absolute path to the viewer command to use, and it can contain | |
| 45 | command arguments as well. The trace directory paths are passed to | |
| 46 | the 'VIEWER' command as its last arguments. | |
| 47 | + | |
| 48 | Default: `babeltrace`. | |
