iostat
iostat(1) General Commands Manual iostat(1)NAME
iostat - Reports I/O statistics
SYNOPSIS
iostat [drive...] [interval] [count]
OPERANDS
Forces iostat to display specific drives. If drive is not specified (or the specified drive does not exist on the system or cluster,
iostat displays the first two drives (even if more than two disk drives are configured in the system). Causes iostat to report once each
interval seconds. The first report is for all time since the system was last booted, and each subsequent report is for the last interval
only.The value must not be 0. Specifies the number of reports. For example, iostat 1 10 would produce 10 reports at 1-second intervals.
You cannot specify count without interval because the first numeric argument to iostat is assumed to be interval.
DESCRIPTION
The iostat command reports the following information: For terminals (collectively), the number of characters read and written per second.
For each disk, the number of transfers per second and bytes transferred per second (in kilobytes). For the system, the percentage of time
the system has spent in user mode, in user mode running low priority (nice) processes, in system mode, and idling.
To compute this information, iostat counts data transfer completions, the number of words transferred for each disk, and the collective
number of input and output characters for terminals. Also, each sixtieth of a second, iostat examines the state of each disk and makes a
tally if the disk is active.
When you issue an iostat command on a cluster member, it displays statistics only for those disks that are local to the member and that
member's usage of those shared disks that it has mounted. It displays 0 for other disks in the cluster (those it doesn't have mounted),
regardless of whether they are on the shared bus or are local to some other member.
EXAMPLES
The output from this example displays cpu, terminal, and disk statistics for the first two disks on the system providing 5 reports at 1
second intervals:
# iostat 1 5
tty floppy1 dsk9 cpu
tin tout bps tps bps tps us ni sy id
0 3 0 0 0 0 1 0 4 95
4 58 0 0 0 0 1 0 2 97
1 53 0 0 0 0 0 0 2 98
5 59 0 0 0 0 1 0 1 98
6 60 0 0 0 0 1 0 2 97
The second example specifies device names in the command:
# iostat dsk2 dsk3 cdrom2
tty dsk2 cdrom2 dsk3 cpu
tin tout bps tps bps tps bps tps us ni sy id
0 13 11 5 5 2 2427 1213 0 1 1 98
