Creating a VLUNs IO Time and Size Distribution Report
The VLUNs IO Time and Size Distribution report displays two charts: I/O Time and I/O Size for
access counts over a time interval or at a specified time.
The I/O Time report displays the read, write, or combined read and write access count for service
times within the specified interval. Each service time is shown in a different color on the same chart.
The X-axis (category) represents time, and the Y-axis (value) indicates the access count.
The I/O Size report displays the read, write, or combined read and write access count for the I/O
sizes within the selected range. Each I/O size is shown in a different color on the same chart. The
X-axis (category) represents time, and the Y-axis (value) indicates the access count.
