I see you're putting all of the stuff into one CFG file. I think
this is bad as you'll probably get name conflicts which is what I
think is causing your duplicate graphs. also, a big CFG takes ages
to run, I much prefer to be able to run them sequentially, or
parallel them at my choice.
I use indexmaker to create an index for each cfg, and then use some
PHP on the server to find and list the indexes available.
The indexmaker call inserts the PHP, something like
indexmaker --title="Main Stats" --columns=2 \
--pagetop="Generated: `date`<br><?PHP include('head.inc'); ?>" \
iwr.cfg > /usr/local/www/data/mrtg/index.html
'head.inc' contains php to find and list any file named
that is NOT 'index.html'
So this cfg is the main one, and all others are sub pages.
Sub pages get a slightly different header, it just has a 'back' link
to the index.html file
You are welcome to the php,
see it in action here http://iwr.ru.ac.za/mrtg
Also, if you're going to do separate cfg's you should maybe delete
all old data so you know you are starting fresh.
oh, have you checked how many rrd files you've got and whether they
all get updated or not? if you have as many files as you've got
targets in the CFG, then they may be updating correctly but the index
is wrong causing incorrect displays. if some of the rrd's don't
exist or don't get updated, the problem lies outside of indexmaker.
