   * Setting up the graphite monitoring engine
   * Configuring to feed xAP
+===== Introduction =====
+Where as cacti uses a __pull__ mechanism to reach out and gather statistics which requires something to cache previous values until the cacti back-end is ready to get them.  Graphite on the other hand uses a __push__ mechanism which is much simpler.  It also means that as new xAP data elements are created they are automatically fed into your charts with zero additional work, unlike cacti which requires lots of extra effort for each new item you want to store and graph.
+Its the preferred charting solution for xAP data.

-The sample applet that can feed data to a Carbon data aggregator is called graphiteApplet.lua and can be found in the plugboard samples directory.
+The sample applet that can feed data to a Carbon data aggregator is called [[http://code.google.com/p/livebox-hah/source/browse/branches/portable/userapps/hah/xap-plugboard/samples/graphiteApplet.lua|graphiteApplet.lua]] and can be found in the plugboard samples directory.
-The only change require is to adjust the IP address in the sample to that of your server.

 graphite={port=2003,host="192.168.4.46"}
 </code>
+Copy the sample to the /etc/plugboard directory, edit, then restart the plugboard engine
+<code>
+/etc/init.d/xap restart plugboard
+</code>
+By default the applet will feed all xAPBSC.event data items to the back-end for recording and charting, along with the [[http://www.xapautomation.org/index.php?title=xAP_Weather_Schema|weather.data]] schema.   Adjust the code to suit your environment.
