Table of Disks

In many cases, disk data is most effectively viewed as a table. In this example, the disk statistics have been formatted into a table as well as text. Tables can be sorted by either percent busy or average service time, so that the most critical data is presented at the beginning of the table.

The -dtoo switch has been used to format disk statistics into the following table.

Disk Device Statistics Results sorted by Average Percent Busy
Disk Device	Average Percent Busy	Peak Percent Busy	Queue Depth when occupied	Average Service Time
hdisk5	20.30	27.0	0.0	0.0
hdisk0	7.30	9.0	0.5	0.0
hdisk2	2.30	5.0	0.0	0.0
hdisk4	2.20	3.0	0.1	0.0
hdisk6	0.00	0.0	0.0	0.0
hdisk1	0.00	0.0	0.0	0.0
hdisk3	0.00	0.0	0.0	0.0
hdisk7	0.00	0.0	0.0	0.0

The following disk analysis has been sorted by the average percent of time the disk was busy.

The disk device hdisk5 was busy an average of 20.30 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk0 was busy an average of 7.30 percent of the time and had an average queue length of 0.5 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk2 was busy an average of 2.30 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk4 was busy an average of 2.20 percent of the time and had an average queue length of 0.1 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk6 was busy an average of 0.00 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk1 was busy an average of 0.00 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk3 was busy an average of 0.00 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.

The disk device hdisk7 was busy an average of 0.00 percent of the time and had an average queue length of 0.0 (when occupied). This indicates that the device is not a performance bottleneck.
