Hello,

I'm wanting to monitor zpool disks. I'm pushing for each zpool:
 - the size of the zpool.
 - the used size of each zfs into it.

So I'd like to get a graph per zpool showing this.

Can I have more than one graph per test.

How can I do to graph this plot ? Currently my data are grouped by zpool
in one rrd.

Regards
