Are the switches grouped by -A on AIX different than on Linux? Sorry, but I don't get exactly what the problem is. If they are different, maybe put the needed switches together one by one. Or use vmstat, iostat,...

Hi All,
I am trying to run sar on a Redhat server during a test I am performing for a couple of hours. I would like to get the sar metrics for every second (instead of the regularly set up 10 minute interval in the cron). What is the most efficient way to do this?
Thanks,

IOSTAT(1) General Commands Manual IOSTAT(1)
NAME
iostat - report I/O statistics
SYNOPSIS
iostat [ drives ] [ interval [ count ] ]
DESCRIPTION
Iostat iteratively reports the number of characters read and written to terminals per second, and, for each disk, the number of transfers
per second, kilobytes transferred per second, and the milliseconds per average seek. It also gives the percentage of time the system has
spent in user mode, in user mode running low priority (niced) processes, in system mode, and idling.
To compute this information, for each disk, seeks and data transfer completions and number of words transferred are counted; for terminals
collectively, the number of input and output characters are counted. Also, each sixtieth of a second, the state of each disk is examined
and a tally is made if the disk is active. From these numbers and given the transfer rates of the devices it is possible to determine
average seek times for each device.
The optional interval argument causes iostat to report once each interval seconds. The first report is for all time since a reboot and
each subsequent report is for the last interval only.
The optional count argument restricts the number of reports.
If more than 4 disk drives are configured in the system, iostat displays only the first 4 drives, with priority given to Massbus disk
drives (i.e. if both Unibus and Massbus drives are present and the total number of drives exceeds 4, then some number of Unibus drives will
not be displayed in favor of the Massbus drives). To force iostat to display specific drives, their names may be supplied on the command
line.
