Key Builders

An aggregation scheme consists of keys and values. Within an aggregation period, each value within flows having the same set of keys is aggregated (typically summed) together with the corresponding values from earlier matching flows within an aggregation period.

Fields are not referenced directly by an aggregation scheme; instead, a key builder or value builder references a field, and one or more aggregation schemes references the builder.

Clicking on the Key Builders folder of the NFC UI navigation tree displays a table of currently defined key builders as shown in Figure 2-10. Click Edit to modify a specific key builder, or Remove to remove a selected key builder. Click Add Key Builder to bring up an empty form for defining a new key builder.
