By default the <EXTRA_DATA TITLE> is the same as the metric name. However if
you add a Title="blah" to any Metric{} block in gmond.conf file, that title is
reflected in the <EXTRA_DATA TITLE> tag. This way the user is able to name
their own graphs and constant metrics anything they want (provided the web
frontend is refactored to use the TITLE rather than the NAME attribute). You
aren't seeing any difference now because I haven't added any titles to the
gmond.conf file. But all of the functionality is there and works. The web
frontend just needs to support it.
