[mrtg] Re: Two Questions (scale and archives)

[Shane Hickey]

First off, thanks to everyone for the info on these questions.  I've decided 
to use the Unscaled but set the MaxBytes to something more reasonable 
(because when I graphed ethernet traffic, you couldn't really see a lot of 
the graphs)  Then I used AbsMax so that if my "reasonable" max was exceeded I 
couldn't lose graph data.  Thanks to Paul Williamson for this idea.

As far as the archives idea.  I ended up setting up MRTG to generate rrd 
logfiles.  Then I'm using 14all.cgi for my basic viewing and a modified 
version to look at the archives.

Thanks much,

Shane
