iostat -k in Solaris (SunOS 5.10)

Question

In Linux iostat -k displays kB_read kB_wrtn fields, which are total data read/written during the measured interval.

#iostat -k
Device:            tps    kB_read/s    kB_wrtn/s    kB_read    kB_wrtn
sda               0.59         3.69        10.46   12418161   35236147

Is there any possibility to display the same in Solaris?

Answer 1

try iostat -xn... I think the output is similar to Linux.

Answer 2

iostat -sndx 1 will produce this output:

The 1 argument specifies emitting an output set once per second. Add a second numerical value to specify how many sets of output are emitted. The first set out output is the I/O statistics since the counters were last reset, probably at boot.

Add -z to suppress rows with all zeros.

Add -p to see per-partition statistics.

Add -I to see raw counts instead of rate numbers. (Might only be Solaris 11)
