To shorten the resource kinds list, type all or part of the resource kind in the Search text box and click the
arrow next to the text box.
n
To use looping functions in array mode, type brackets to enclose the array and type commas between each
value.
n
Use values that are the same type, either single values or arrays.
Arrays are defined when you select a resource kind and attribute kind instead of a particular metric.
n
Select a resource kind and single metric only as part of the argument for a looping function.
If you select a resource kind, you must select an attribute kind.
n
To see the formula with resource and metric names instead of IDs, click the Show Formula Description
icon in the area beneath the formula line.
n
To select function names and formats and arithemetic operators, either type them directly on the formula
line or select them from the drop-down menus.
n
To use parentheses to specify the order of operations in the formula, either type them directly on the
formula line or select them from the Operators drop-down menu.
n
To clear the metrics or attribute kinds lists, click the Clear Selection icon in the Resources or Resources
kind pane at any time.
Add a Super Metric
You create a super metric when only a combination of metrics can let you know if your systems are behaving
normally.
When you add a super metric, you might find it helpful to open two vCenter Operations Manager browser
tabs. For example, you can create the super metric in one tab and view a dashboard that shows the Resource
Selector, Metric Selector, and Metric Graph widgets in the other tab. When you use two tabs, you can also see
the metric graph of a metric and verify that it is correct before you use it in a super metric.
Prerequisites
n
Design your super metric formula. See “Design a Super Metric,” on page 46.
n
Become familiar with the user interface for building super metric formulas. See “Build a Super Metric
Formula,” on page 49.
Procedure
1 Select Environment > Advanced > Super Metrics > Super Metric Editor.
2 Click the Add New Super Metric icon.
3 Type a name for the super metric in the Super Metric Name text box.
4 Define the formula for the super metric.
Select, in order, each function or operator to use and the metrics or attribute kinds to use in each function
or with each operator.
5 To verify the formula, display a metric graph that shows what its value was during a past time period.
a Click the Visualize Supermetric icon.
The metric graph pane replaces the Metrics and Attribute Kinds panes.
b If you are prompted to select a resource, select the resource to which to assign the super metric in the
Resources pane.
c Click the Data Controls icon and select the date range for the data.
