Weight values are assigned to ICIM classes and instances in the weights.conf file.
Weights can be assigned to any class or instance by specifying one of the following keywords:
The syntax in the file is as follows:
ClassWeight <class_name> <value> InstanceNameWeight <class_name> <DisplayName> <value> InstanceNameWeight <class_name> <full_instance_name> <value> InstanceWeight <class_name> <instance_name> <value>
For the keyword InstanceNameWeight, business classes are specified by their DisplayName, without a prefix. For all other classes, you must specify the <full_instance_name>, or the complete name of the element, including the prefix of the element. For <instance_name>, you can specify the DisplayName or you can specify a wildcard pattern. The symbols for wildcards are listed and described in the weights.conf file.
When you assign weight values to elements, categorize the elements according to their importance within your environment. Then, assign greater values to the elements that are more important to your business.
ClassWeight ICIM_ManagedElement 1 InstanceNameWeight BusinessProcess Inventory 4000 InstanceNameWeight Application APP-Inventory Service 4000 InstanceWeight Router *[Gg][Ww]* 1000
Similarly, you can assign varying weights to service subscribers:
ClassWeight Organization 1000 ClassWeight BusinessUnit 1200 ClassWeight LOB 1400 ClassWeight Department 1600 ClassWeight Customer 1800
In Business Impact Manager’s calculations, the weight assigned to an instance takes precedence over the weight assigned to a class, and the weight assigned to a subclass takes precedence over the weight assigned to the parent class.
