cgdb is a lightweight curses (terminal-based) interface to the GNU Debugger (GDB). In addition to the standard gdb console, cgdb provides a split screen view that displays the source code as it executes. The keyboard interface is modeled after vim, so vim users should feel at home using cgdb.

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