The Peek Processor populates a transaction attribute with a specified number of bytes (from the start of the transaction data stream) as a string.
Select the Processor Configuration tab and click on Add Processor.
Select the Peek Processor from the drop-down.
Select the Basic tab.
Here, the user can specify:
Transaction Attribute Name: the name of the transaction attribute, in which the result of the processor will be recorded.
Peek Length: the number of bytes to load from transaction data.
Encoding Type: the character encoding type of the string.
In the Conditional Execution tab, you can set additional processor execution conditions. The Transaction data dependent condition may be specified here as enhanced expression. If this expression returns anything other than TRUE (ignore case) – this processor will be skipped. No additional configuration for this Processor is required.
