From the iostat(8) man page:
SEE ALSO
fstat(1), netstat(1), nfsstat(1), ps(1), systat(1), pstat(8),
vmstat(8)
What information are you looking for specifically?
Have a look at systat(1). It presents the activity on your system
nicely, breaking it down into several descriptive categories which
are documented in the man page.
Try this:
$ systat -io
Hope that helps,
