Working with vFoglight Rules and Registry 265

Working with Rules

In the Condition tab, use the Condition area to write the conditional expression.

You can type the condition directly into the Condition box, or use the operator

controls and the Condition Editor to add logical operators, registry variables,

metrics, or Groovy functions. For complete information about inserting operators

or using the Condition editor, see “Specifying a Rule Condition or Derived Metric

Expression” on page 481.

Caution If you change the metrics, registry variables, or topology object properties that are

referenced in the condition, ensure that the new items are available for the

topology type or object(s) to which the rule is scoped.

Important To separate multiple lines in conditional expressions, use a semicolon followed

by a carriage return. In conditional expressions consisting of a single line, using a

semicolon to end the line is optional. For example:

Multi-line expressions

Example A

Correct

println @event.dump();

@event.get("report/name") == "MyReport";

Incorrect

println @event.dump()

@event.get("report/name") == "MyReport";

Note The first line is missing a semicolon which causes the expression

to result in an error.

Single-line expressions

Example B

Correct

println @event.dump();

Example C

Correct
