  76 >&#13;Linux Trace Toolkit (LTT) is a tracing tool that permits to get all the possible
  77 execution information from the Linux Kernel. It is based on kernel
  78 instrumentation and a high-speed relay file system to copy the information from
  79 the kernel space to the user space.

  82 >&#13;Linux Trace Toolkit Viewer (LTTV) is the second generation of visualization
  83 tool. It is
  84 based on a trace format (the files where the data is recorded on disk) slightly
  85 different from LTT. As for now, November 29, 2004, the implementation of the new
  86 trace format in LTT is still not done, we must use a conversion tool to
  87 transform the original LTT traces to the new format.

  90 >&#13;This document explains all the steps that are necessary in order to record a
  91 trace with LTT and view it with LTTV.
