Creating Reports in a Complex Environment2
Independent Classes - Asset, Chargeback, Discovery details, and Tape Library are independent
classes. They do not interact with any other class, and the queries involving these classes cannot be
combined with other classes. For example, you cannot combine objects from the Asset class and
the Host class.
If you are interested in generating a report that contains independent classes, a different query must
be added to the same report. The output can be obtained in the same report on the same page, or
on a different tab.
For additional information, see ”Context Types” on page 16.
Class Categories - The names of the classes in the universe are self explanatory and describe what
the purpose of each class is. A few classes are repeated with additional text in the class name. The
purpose of the class or sub-class is defined by additional text within the class name. The following
table lists the categories and what they mean:

Category What it means Example
Dependency Use these classes and sub-classes
when you are interested in
dependency information.
For a full description of dependency
classes, see “Context Descriptions”
on page 16.
Host > HBA
This class lists all of the HBAs for the
given host.
Host > HBA for Dependency
This class lists only the HBAs that are
connected to fabric.
Capacity/
Performance
Statistics - Latest
Collectors periodically capture every
element statistic. The “Latest” class
of statistics always contains the most
recent values for the object.
Use this class if you want to find the
most recent value of the object.
Host > Host Capacity Statistics - Latest
Host > Host Performance Statistics >
CPU performance Statistics - Latest
Capacity/

Historical
Collectors periodically capture every
element statistic. These stats,
collected for every interval, are
represented in the “Historical”
statistics class.
Use this class if you are interested in
trending or change management.
