[hobbit] iostat

[Everett, Vernon]

Hi Henrik

Ok, let's say I was daft enough to give this a go.
I want to generate graphs of my disks.
On linux, I have sda and sdb
On Solaris, c0t0d0, c0t1d0 and c0t2d0
Not a problem.
I generate output, configure my graphs, get the rrd files to auto-generate, and life is good.
But now I add another disk!

The only solution I can see is to have a separate rrd file per disk, the way you handle disk capacity.
How do I tell the ncv module to put each disk into a different rrd file, instead of dumping it all into one, like it seems to like doing?

Cheers
    V

Don't think so. The standard Hobbit client doesn't collect these data, and there's nothing on the server that knows how to parse it anyway.

(I agree it would be nice to collect those stats - and mpstat as well).
