Working with Derived Metrics
The vFoglight Management Server processes the derived metric calculation in the order
they are listed, starting with the first one. Changing their order affects the behavior of
the actions that are associated with the derived metric.
For example, if there are two calculations whose conditions evaluate to True, the first
calculation listed takes precedence, causing one or more actions that are associated with
that metric to be generated before the next one.
For detail information on how to scope a rule or derived metric to one or more topology
objects, see “Using the Query Language” on page 473.
To get started with adding calculations to a derived metric:
Note This procedure continues from “Getting started with derived metric definitions” on page 344
or “Viewing and editing derived metrics” on page 341.
