These vmstat rrds are from back on larrd 42; just after the change to
accumulate cpu wait. So I'm trying the vmstat recreate to see if the
definitions I've got are severely non-standard (I'd almost bet on it)
If so, I'll see what I need to hack to keep my current data . . .
On the disk space rrds -- this is a lot of wasted activity for us; we
have about 8 filesystems we care about, and my production R3 DB server
currently has 95 filesystems that have been 100% full since creation --
and we add another 10 every 13 months (150 GB -- SAP just *eats* disk).
If I can't suppress the creation, I'd at least like to suppress the
display of the graphs -- they're meaningless noise in our shop.
Not a showstopper for going live Monday, though -- If I can figure out
the vmstat issue.

I've looked over the AIX setup for vmstat, and it should parse this
output from the bottomfeeder OK.
Is this RRD file one that you have copied over from the BB/LARRD setup ?
If yes, do the graphs make more sense if you delete the file from
~hobbit/data/rrd/HOSTNAME/vmstat.rrd and have Hobbit re-create the file
(it does that automatically) ?
I'd like to have a look at that vmstat.rrd file to see if the problem is
one of different data-set definitions in the Hobbit vs. LARRD version.
I know the vmstat definitions are different on some systems, but I
cannot remember if I changed them for AIX also.

The data for them are being tracked, but by default only one vmstat
graph is shown. Add
"LARRD:*,vmstat:vmstat|vmstat0|vmstat2|vmstat3|vmstat8" to the entries
in the bb-hosts where you want these.

There's no way to turn off tracking of the data for disk reports (unless
you configure the client not to send them, of course).
