Logic Check

The Logic Check processor enables users to perform a logic check, using multiple criteria to route or filter records.

Use

The Logic Check processor is normally used as a way to filter records to a required set. For example, if all records are passed through a number of checks, it may be useful to add a Logic Check at the end to select which records are considered as overall passes and fails, using the Flag attributes added by other audit processors.

Logic Check may also be used to filter down records to a specific set where the data matches a number of criteria across a number of attributes.

Configuration

Inputs

Any number of attributes of any type (except arrays).

Options

Option	Type	Purpose	Default Value

Note that the options specified drive the construction of an expression that is used to filter records. It is also possible to edit the expression directly, once you have mastered how the expressions are written. The expressions may also be used in the Expression Filter custom processor.
