  35                 <p>While the Eclipse plug-ins can run on the standard Eclipse platforms (Linux, Mac, Windows), the LTTng tracer and its accompanying tools run on Linux.</p>
  36                 <p>The tracer and tools have been available for download in Ubuntu since 12.04. They can easily be installed with the following command:</p>
  37                 <pre>
  38   &gt; sudo apt-get install lttng-tools
  39 </pre>
  40                 <p>For other distributions, older Ubuntu distributions, or the latest, bleeding edge LTTng tracer, please refer to the
  41                         <a href="http://lttng.org/download">LTTng website</a> for installation information.
  42                 </p>
  43                 <p>
  44                         <b>Note</b>: The LTTng tracer (and accompanying tools) is required only if you want to create your own traces (the usual case). If you intend to simply analyze existing traces then it is not necessary to install the tracer.

  47                 <p>The easiest way to install the LTTng plug-ins for Eclipse is through the Software Updates and Add-ons menu. For information on how to use this menu, refer to this
