Viewing Capacity Charts
Capacity Manager provides a graphical representation of the capacity history of an element, such
as port summary information for switches.
You can manipulate the charts, so they show a different reporting period and frequency. For
example, you could show the capacity of a host over the past 24 hours with an hourly monitoring
frequency.
Keep in mind the following:
• Verify the performance collector for the element is enabled (Optimize > Storage Essentials >
Performance Data Collection
). See ” Managing Performance Collection ” on page 193 for
more information about enabling performance collectors.
• Switches and storage systems display data from the last time Discovery Data Collection/Get
Details was performed. See ” Step 1 - Discover Switches ” on page 31 for more information.
• If you see “There is not enough data to produce a chart [chart_title] at this time.” message,
lessen the frequency option, so that the amount of time listed in the Frequency drop-down menu
has passed before you view the chart again. For example, if the Frequency menu displays
hourly, you need to wait an hour for data to appear in the chart.
To find the performance of an element:
1. Access Capacity Manager as described in ” Accessing Capacity Manager ” on page 517.

when you click the chart and moving the mouse.
