It can be used to obtain accurate and up to date information on the performance of a number of systems. <p>Currently the "suite" consists of these parts:</p> <ul> <li><dfn>symon</dfn> - lightweight system monitor. Can be run with privleges equivalent to <em>nobody</em> on the monitored host. Offers no functionality but monitoring and forwarding of measured data.</li> <li><dfn>symux</dfn> - persists data. Incoming symon streams are stored on disk in <a href="http://www.google.com/search?q=rrdtool&btnI=1">rrd files</a>. symux offers systems statistics as they come in to 3rd party clients.</li> <li><dfn>syweb</dfn> - draws rrdtool pictures of the stored data. syweb is a php script that can deal with chrooted apaches. It can show all systems that are monitored in one go, or be configured to only show a set of graphs. </li> <li><dfn>sylcd</dfn> - symux client that drives <a href="http://www.crystalfontz.com">CrystalFontz</a> and HD44780 lcds. sylcd shows current network load on a specific host.</li> <li><dfn>SymuxClient.pm</dfn> - generic perl symux client. Could, for instance, be used to get the hourly amount of data that was transmitted on a particular interface.</li> </ul> </div> <div class="line"></div> <div class="copyright">Copyright © 2001-2022 <a href="mailto:wpd@xs4all.nl">Willem Dijkstra</a></div> </body> </html>
