>&#13;Linux Trace Toolkit (LTT) is a tracing tool that permits to get all the possible
execution information from the Linux Kernel. It is based on kernel
instrumentation and a high-speed relay file system to copy the information from
the kernel space to the user space.
</P
><P
>&#13;Linux Trace Toolkit Viewer (LTTV) is the second generation of visualization
tool. It is 
based on a trace format (the files where the data is recorded on disk) slightly
different from LTT. As for now, November 29, 2004, the implementation of the new
trace format in LTT is still not done, we must use a conversion tool to
transform the original LTT traces to the new format.
</P

>&#13;This document explains all the steps that are necessary in order to record a
trace with LTT and view it with LTTV.
