Creating a Logical Disks Performance Statistics Report
The Logical Disks 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:

types.) Time

Number of write operations per second. Write IOPs/s
Total number of (read + write) operations per second. Total IOPs/s
Read bandwidth in kilobytes per second. Read KBytes/s
Write bandwidth in kilobytes per second. Write KBytes/s
Total (read + write) bandwidth in kilobytes per second. Total KBytes/s
Average read service time in milliseconds. Read Svct ms
Average write service time in milliseconds. Write Svct ms
Average total (read + write) service time in milliseconds. Total Svct ms
Average size of read operations, in kilobytes. Read I/O Size
