I like to have interfaces and description, not one or the other. So I do this. Use your favorite editor to open indexmaker: vi /usr/bin/indexmaker

Find this part:

for ($$opt{section}) {
# ...Skip ahead to descr...
/^descr(iption)?$/ &&
do{
$section = "No Description for $item";
$$rcfg{setenv}{$item} =~ /MRTG_INT_DESCR="(.+?)"/ #"
and $section = $1;
$$rcfg{pagetop}{$item} =~
m,<td>Description:</td>\s*<td>\Q$section\E\s*([^< ][^>]+?)

,i
and $section = $1;
last;
};


The first “and $section = $1;” is a catch all to assign the interface name if there’s no description. The second one overwrites it, replacing the int name if it does find a description. So all you need to do is modify the second instance of “and $section = $1;” to:

and $section = $section . " - " . $1;

And your MRTG index is infinitely improved!
