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.

Well, I see what is going on, and I don't want to try to explain it --

The vmstat rrd for all my AIX systems has the data elements defined in alpha sequence: cpu_b, cpu_csw, cpu_idl, cpu_int, cpu_r, cpu_syc, cpu_sys, cpu_usr, cpu_wait, mem_avm, mem_cy, mem_fr, mem_free, mem_pi, mem_po, mem_re, and mem_sr.

Hmm. Seems that the vmstat rrds for my two SuSE linux boxes are also in alpha sequence. I'm not real strong in perl, but I suspect this is the culprit: foreach $col ( sort keys %{$htovm{$bbhosttype}}) { push @ds,"DS:$col:GAUGE:600:0:U";

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.

Short term, I'm going to change do_vmstat.c, while I research writing some code to re-work the rrd xml (too many changes and too many rrds to try it by hand).

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

The disk patch is much appreciated; our primary R3 DB server should drop from 31 disk graphs down to three just by excluding '/oracle/PRD/sapdata*'.

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