Creating a Physical Disk Performance Statistics Report
The Physical Disk 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:
