[hobbit] some larrd issues on hobbit 4.0.3 rc1

[Kauffman, Tom]

IIRC, the vmstat graphs were among the very first items to be set up in
larrd, and he was learning rrd at the time. Now don't hold your breath,
but I will pass the conversion tool along to you whenever I get it
working. It's just not going to be all that high on my list. This is the
year we swap out virtually every AIX system we've got because the lease
is up, and the fun starts early next month.

Perl is definitely not my strong side either - one more reason why I
abaondoned the LARRD perl-scripts.

I looked at the one remaining BB server I have, and it seems you're
right - LARRD really does sort the datasets alphabetically by name when
it sets up the vmstat RRD file. It seems it does this only for the
vmstat data.

If you do come up with a tool for this, I would appreciate it if I may
distribute it with Hobbit.

Dont forget that this is a regexp - I think you meant
'/oracle/PRD/sapdata.*'  
with a dot before the asterisk.
