As a more general point:  The data-handling and data-display aspects of
MRTG have been separated out into a general purpose "rrdtool".  And within
that, the data-handling and data-display are themselves cleanly separated.
which also gives several examples of the sorts of data folk are collecting
and logging with rrdtool:

I, too, had trouble trying to hook "" onto MRTG.  And
coercing also "felt" intuitively flawed.  The "rrdtool"
interface feels better and cleaner.

Could I suggest that the MailScanner project (Julian Field and/or Nick
Phillips) consider replacing (perhaps in a phased manner) references to
MRTG by references to rrdtool?

Using "rrdtool" still requires a reasonable amount of "getting to grips"
work if starting from scratch.  But, as part of the above, general
guidelines for our MailScanner activities could be prepared for folk to

Hope that helps.
