Hi Allen

Out of curiosity, the 2) isnt the total filespace capacity right, but the used 
amount on each filespace? Or are you looking at some other number?

Regards

Daniel

I'm doing this, crudely, right now as I try to characterize our
hosting customers behavior, to identify outliers.

Here's what I'm doing:


1: sum "Yesterday's" sessions, per-node.  This is from the actlogs.

2: total filespace capacity, per-node.

3: Divide 1 by 2.

4: Discard outliers.  I have some zeroes, and I have some 100+ %: the
    latter tend to be database backups and erroenous reads on capacity
    (like a nas filespace which is technically terabytes large, but
    looks small on a 'q filespace').

5: Do (elementary) statistics on the results.
