[Hyperic-hq-discuss] ZFS filesystem support with sigar iostat

[sberthol <sig...@hy...>]

Hi,

Trying to get io statistics with sigar iostat (jar version with latest 1.7.0 from git repository) on a ZFS filesystem (on solaris 10 64b), I always the following error:

sigar> iostat /local
Filesystem      Mounted on           Reads     Writes R-bytes W-bytes Queue Svctm
local           /local                  -1         -1       -       -     -     -

while iostat works without any problem with an UFS fielsystem on the same host:
sigar> iostat /
Filesystem      Mounted on           Reads     Writes R-bytes W-bytes Queue Svctm
/dev/dsk/c0t0d0s0 /                    18065      18856    168M     32M  0.00  0.00


Is it an already known issue ? Or is there a way to get the actual R/W numbers from a zfs filesystem ?

Thanks and regards,
Seb
