15.0 Using Algorithms to Calculate Element State

By default, an element’s state is calculated simply by inheriting the condition of it’s most critical child element.

Optionally, alternate algorithms are used to apply a sequence of calculations to control state propagations and update with conditions that more accurately reflect the overall status of the Business Service View in which the element resides.

For example, if two Web servers support a Web store application, but only one is necessary to run it correctly, then an algorithm can be applied to the parent of the two servers allowing the state of the WebStore application to show as available as long as at least one Web server is running normally.

The following sections describe how to use algorithms to calculate element conditions:
