76 | > 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. |
80 | </P |
81 | ><P |
82 | > 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 | > This document explains all the steps that are necessary in order to record a |
91 | trace with LTT and view it with LTTV. |
