DESCRIPTION

The LTTng project aims at providing highly efficient tracing tools for Linux. Its tracers help track down performance issues and debug problems involving multiple concurrent processes and threads. Tracing across multiple systems is also possible.

The lttng-crash command line tool, part of the lttng-tools package, is used to view or recover trace buffers in the event of a crash.

-h, --help

-v, --verbose
