The Rules tabs in the Services Config view ( AdminIcon_25x22.png (Admin) > Services > select a service and click actionDD.png > View > Config) enable you to define and manage capture rules. Each type of rule has a list with slightly different columns and different parameters in the Rule Editor dialog. Application and correlation rules apply to both Decoders and Log Decoders. Network rules apply only to Network Decoders.


The following figure depicts the workflow for common Decoder configuration tasks with the steps you can complete in this view highlighted.
