Configuring Event Correlations: Correlation Expression Components

Correlation Expression Components
The following illustrates a basic expression configuration:
Figure 14-1 Correlation Expression Example
A Term in a correlation expression is used to test the current state of an originator.
The Term consists collectively of the following elements:

Originator Type, which is one of the Remote RMX-3200 event originator types.
The type can also be
correlation
, which refers to other event correlations.
 Instance value, which is one of the valid instances for the specified type, for
example,
0/1
,
2
.

State, which is a valid state for the originator. In the case of a measurement, the
state may be a relational operator and a numeric value (for example,
< 48
or
>
95
).
Originator Types and States
Table 14-1 lists the types of originators that are valid for the correlation expressions,
the associated events that are valid as a state comparison and those originators that
can be used as multi-originators. Multi-originators must have either an
any
or an
all
operator before the multiple instance token. See Operators on page 14-4 for details.
