At least one group type must be selected.

You can group chart reports by one or more of the following attributes: Port Type (default),
Port Node, Port Slot, Port Number, and GBITPS (gigabits per second).

c.

In the Show Charts group box, select the checkboxes for one or more charts to display:
IO Time and IO Size. At least one chart type must be selected.

d.

In the Display Metric group box, select how you want to display the access count: Number
or Percentage.

e.

Select how you want to display read/write requests: Combined read/write, Separate
read, or Separate write.

f.

Select the range for the I/O Time Columns: 0.008 to 32768 milliseconds. The default
range is 0.50 ms to 256 ms.

g.

Select the range for the number of I/O operations (I/O Size Columns): 512 bytes to 16

Creating a Ports Performance Statistics Report

The Port Performance Statistics report displays read, write, and total read/write counts in various
service time buckets. Charts can be generated for values over a time interval or at a specified time.
Each access type is shown in a different color on the same chart. The X-axis (category) represents
time, and the Y-axis (value) indicates an access count or access time, depending on the type of
chart.

Y-Axis Units

Chart Type

I/O operations per second.

IOPs

Kilobytes per second.

Bandwidth

Milliseconds.

Service Time

Kilobytes per second.

I/O Size

The number of outstanding I/O requests at the time the sample was collected.

Queue Length

The percentage of time the object is busy.

Average Busy

A table below the charts displays the following statistics:
