Useful for monitoring zpool health, zvolumes, and zfs filesystems which are not mounted

Also zfs-specific stats which can't be seen from node_filesystem metrics (e.g. compressratio)

For whatever it is worth, I use this to track the age of the latest snapshot:

        zfs list -Hp -t snapshot -o name,creation \
          | sed -e 's#@.*\s# #' \
          | awk '
              {
                if (last[$1] < $2) {
                  last[$1]=$2
                }
              }
              END {
                for (m in last) {
                  printf "zfs_snapshot_age_seconds{dataset=\"%s\"} %s\n", m, last[m];
                }
              }
