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.

Something is quite wrong, and I'm not sure what to look at.
Here's what the vmstat bottom feeder ships out:
aix 1 3 2342710 511 0 1 1 2249 14879 0 1964 11870 4215 15 11 31 42
so cpu_usr is 15, cpu_sys is 11, cpu_idl is 31, and cpu_wait is 42.
But the vmstat graph is giving me a system of 0.0, user 1670.0, and idle of 2347945.2.
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.
Also -- I only get the vmstat graph for AIX - I'm missing vmstat0, vmstat2, vmstat3, and vmstat8. Where do I enable the graphing for these?
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.
And while I'm at it -- I need to disable the tracking and displaying of disk filesystem usage data -- virtually all my filesystems contain Oracle tablespaces and they are 100% full at the OS level shortly after creation -- so I can't see any reason to track them.
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).
