Viewing a Controller’s CPU and Network Utilization
You can use Xsan Admin to view graphs of up to 7 days of overall CPU, IP network, and
Fibre Channel network utilization data for a controller.
To view utilization graphs:
1 Open Xsan Admin and connect to the controller.
2 Select the SAN in the SAN Components list and click Graphs.
3 Choose the type of data you want to graph from the Show pop-up menu and choose a
computer from the On pop-up menu. Use the slider at the bottom of the window to
adjust the time period displayed in the graph.
To turn off the mathematical smoothing of the graphs and see data points only, choose
Xsan Admin > Preferences and disable “Smooth graphs under 12 hours.”
