 XML parsing is done using the following; | 
 
 
 
 
 
 | 6 | 
   | 
   | 
  | 
 
 
 
 
 
 | 7 | 
   | 
   | 
 XML::Parser perl module |

   | 
   | 
 Both of those need to be installed first. | 
 
 
 
 
 
 | 14 | 
   | 
   | 
  | 
 
 
 
 
 
 | 15 | 
   | 
   | 
 Finally, rrdtool is needed for graphing. It can be found here; |

   | 
   | 
  | 
 
 
 
 
 
 | 17 | 
   | 
   | 
 RRDTool | 
 
 
 
 
 
 | 18 | 
   | 
   |

 | 19 | 
   | 
   | 
  |

   | 
   | 
 With that lot installed, start watch.pl; | 
 
 
 
 
 
 | 21 | 
   | 
   | 
  | 
 
 
 
 
 
 | 22 | 
   | 
   | 
 ./watch.pl iscreamserver.domain.com 4510 | 
 
 
 
 
 
 | 23 | 
   | 
   | 
  | 
 
 
 
 
 
 | 24 | 
   | 
   | 
 This will generate the rrdtool databases from the live data the i-scream server provides. | 
 
 
 
 
 
 | 25 | 
   | 
   | 
  | 
 
 
 
 
 
 | 26 | 
   | 
   | 
 ./graph.pl | 
 
 
 
 
 
 | 27 | 
   | 
   | 
  | 
 
 
 
 
 
 | 28 | 
   | 
   | 
 This will generate the graphs. This is best run on a cron job. |
