Netdata collect informations

[thefiredragon]

Dear all, we're collection informations for netdata integration,
States if an pool is degraded, online or failed we found under:
/proc/spl/kstat/zfs//state

Now we would like to know if also the general pool stats are linked to a file which we see under zpool list.

$ zpool list
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
data1 1.81T 107G 1.71T - 3% 5% 1.00x ONLINE -
data2 5.44T 3.55T 1.88T - 38% 65% 1.00x ONLINE -
Any ideas where these metrics come from?

Also we would like to know what the metrics says under:

/proc/spl/kstat/zfs/
