The LTTng project aims at providing highly efficient tracing tools for Linux. Its tracers help track down performance issues and debugging problems involving multiple concurrent processes and threads. Tracing across multiple systems is also possible.
The Linux Trace Toolkit Viewer (LTTV) is the second generation of the visualization tool. It is based on a trace format (the files where the data is recorded on disk) written by the LTTng tracer.
This package contains the trace reading library and trace viewing tools for the new Linux Trace Toolkit trace format.
