RE: Oh where has my disk space gone?

Oliver,

You've clearly identified the advantage of taking the 80/20 approach.  In
your case, you can watch 850 objects, out of 165,000.  You can track the
growth of these objects, over time, and "know thy enemy".  This is also an
exercise in the (probably out-of-fashion) view "know thy data", knowledge of
which helps solve a vast multitude of problems.

I learned the 80/20 rule the hard way, by working in Retail most of my IT
career.  In Retail, it's more like the 50/50 rule, because everything seems
to be done half-a'd.  It's an experimental approach, as opposed to
Manufacturing companies where the tendency (probably due to corporate
culture) is to spec out IT projects to a lot more detail.

</chit-chat>

The example above shows the value of both approaches.  You can keep a
watchful eye on 80% of the DASD by tracking about .5% of the objects.
