Device Monitoring Studio provides a generic mechanism that can be used to filter the output of different visualizers. You can configure several aspects of each supported visualizer.
You can configure filters and schemes in the Tools » Settings, Filtering Tab.
Each data visualizer that supports Generic Filtering checks each incoming packet if it suits the criteria specified by one or more filters. If packet fails to pass at least one filter rule, it is silently discarded.
Most data visualizers have non-empty default rule set that usually hides packets of lower interest, like answers for outgoing packets (that is, on their way UP).
