There should be one such rule for each type of event to be pretty-printed (events which do not have formatting rules are ignored).</p> <p>A sample format file for Xen's predefined trace events is available in the file tools/xentrace/formats in the Xen source tree.</p> <p>Depending on your system and the rate at which trace data is produced, this script may not be able to keep up with the output of <b>xentrace</b> if it is piped directly. In these circumstances you should have <b>xentrace</b> output to a file for processing off-line.</p> <h1 id="AUTHOR">AUTHOR</h1> <p>Mark A.
