Analyzing Traffic Statistics The traffic statistics reveal the number of I/Os that have been made via ports
from HBAs. They also reveal the amount of data that have been transferred
between ports and HBAs. You must analyze the traffic statistics to determine
upper limit values that should be applied to I/O rates or transfer rates for low-
priority HBAs.
The following is the procedure for using the Server Priority Manager window
to analyze traffic statistics. You can also use the Performance Management
window to analyze traffic statistics. Performance Monitor can display a line
graph that indicates changes in traffic (For details, see Viewing I/O Rates for
Disks and Viewing Transfer Rates for Disks).
To analyze traffic statistics:
1. Start Server Priority Manager.
The Server Priority Manager window is displayed.
2. Select the WWN tab.
3. Select All from the list at the top right corner of the window.
4. Do one of the following:
– To analyze I/O rates, select IOPS from the list at the upper left corner.
– To analyze transfer rates, select MB/s from the list at the upper left
corner of the list.
