based on the metric category to which they belong. Select a metric to view the corresponding
performance graph in the Chart Work Area. You can also click the Metric check box to view
performance graphs for all the metrics listed.

The related metrics are displayed in the Available Metrics Choose Metric Category list, if you select
a homogeneous set of components, where the selected components belong to the same component
type within or across the XP and the P9000 disk arrays. The related metrics can belong to different
metric categories. For example, only the LDEV related metrics are displayed, if you choose Physical
LDEVs under Back-end > RAID Groups.

IMPORTANT:

For a component type, the metrics are displayed for selection only if the corresponding
components are supported or configured in the XP and the P9000 disk arrays.

For example, if the configuration collection is not yet performed for an XP disk array, the CLPR
partition data is not available. Hence, clicking Cache in the component selection tree does
not result in any metrics and the Available Metrics Choose Metric Category list is disabled.
The same logic applies for other components in the XP and the P9000 disk arrays. For virtual
volumes like the ThP and the snapshot pools, the respective component type is displayed if
the selected XP or the P9000 disk array supports that particular component configuration.

If a particular component is not supported in an XP or a P9000 disk array, the related metrics
are not displayed in the Available Metrics Choose Metric Category list. For example, as CLPRs
do not exist in an XP1024 Disk Array, the Cache related metrics are not supported for that
disk array.

If the selected metrics belong to the same metric category, the performance graphs of
components are plotted in the same chart window.

For example, if you selected port CL1E, LDEV 0:06, and the metrics as Avg Port IOPS and
Total LDEV IO – Frontend, the respective performance graphs are plotted in the same chart
window, as both the selected metrics belong to the Frontend IO Metrics category.

If the metrics belong to different metric categories, the performance graphs are automatically
plotted in different chart windows.

For example, if you selected port CL1E and the metrics as Avg Port IOPS and Avg CHA MP
Util (%), the respective performance graphs are plotted in two separate chart windows, as the
metrics selected belong to different metric categories. The Avg Port IOPS belongs to the
Frontend IO Metrics category and the Avg CHA MP Util (%) belongs to the Utilization Metrics
category.

If you select a metric for a component type, the performance graphs are displayed for all the
associated components in the same chart window. For example, if you select the Overall RAID
Group Utilization metric for the Back-end > RG(s) component type, the performance graphs
of all the associated RAID groups are displayed in a single chart window.

You can add performance graphs of components for similar metrics to the same chart window
only if the chart selection is retained in the Chart Work Area. If the existing chart window is
not active, a new chart window is added to the Chart Work Area.

For example, the performance graph of port CL1E is already plotted for the metric Avg Port
IOPS and you choose to plot performance graph of another port CL1F for the same metric.
The performance graph of CL1F is automatically added to the existing chart window that
already has performance graph plotted for CL1E. If the existing chart window is not active,
the performance graph for CL1F is plotted in a new chart window.
