Sorry for the confusion - if I run "iostat" I get this:
[root at foo root]# iostat
Linux 2.4.18-3 (foo) 09/24/2002
avg-cpu: %user %nice %sys %idle
16.79 0.00 26.39 56.82
Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn

dev8-1 11.80 1.67 184.95 403090 44609586
if I run iostat 1 it loops every second, so the results (for the first
16 seconds) are:
[root at foo root]# iostat 1 16

Is that enough or should I post more? iostat -V reports sysstat
version 4.0.3
thanks
