Weighted Severity

WorldView calculates the weighted severity of an object by multiplying an object's numeric severity by the object’s weight.

Note: The weighted severity component of CA NSM uses only the following severity to status mappings:

0=Normal

1=Unknown

2=Warning

3=Minor

4=Major

5=Critical

Example: Calculate Weighted Severity

The default weight assigned to the router class is 60. When you discover all of the routers in your network, each router inherits a weight of 60. However, you have one router (Router A) that is more valuable to your network, so you change the weight of that router to 80.

When an object below Router A changes state, for example, a server is low on disk space and goes critical, that critical severity is propagated to Router A. The propagated severity of Router A is then critical. Because you assigned a weight of 80 to the router, the propagated weighted severity is 400.

If an object below another router (for example, Router B, which has the inherited weight of 60) also changes to a critical state, the propagated weighted severity of Router B is 300. These values are used in the algorithm to derive importance.
