Assigning a Business Cost to a Application
The management server lets you assign a business cost to an application, including virtual applications. This information is used in Event Manager for ranking events from elements. Event Manager determines the rank of an event by taking into account the business cost of the application and the severity of the event. You can sort events by rank in Event Manager by clicking the Rank column.
For example, assume you assigned a business cost of $40 to one application and a business cost of $30 to another application. If an event occurs with the same severity level occurs from both applications. The $40 application has a higher rank because it has a higher "business cost."
The events from the elements in the path of the applications also inherit a business cost from the applications that use it. For example, assume a host has an application assigned a cost of $30. The host would have a business cost of $30. If the host has two applications (both valued at $30), the host would be valued at $60 because the two applications are using it. Likewise the switch connected to the host would also have a value of $60 because the two $30 applications use it. If a switch has a $40 application on one host and two $30 applications on another host, the switch has a value of $100, see the following figure.
The cost of the storage system is determined by the applications in its path. Two storage systems connected to a switch can have different business costs based on the applications in their path. For
