Module: Graph

This module collects statistics from the Linux Traffic Control system. It currently supports gathering statistics from HTB and HFSC. The collected data from the traffic classes are stored in some RRDtool data files. This makes our graph module a RRDtool backend. We highly recommend the RRDtool frontend drraw for displaying the RRDtool graphs. Graphs created with this graph module and drraw are shown in the thesis in Chapter 6 and Chapter 10. The module almost detects everything itself and even creates missing (RRDtool) data collection files. The graph module is fairly independent and could just as well be distributed as a separate tool for collecting traffic statistics from the Linux Traffic Control system.
