Key Builders
An aggregation scheme consists ofkeys 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, akey builder or value builder
references a field, and one or more aggregation schemes references the builder.
Clickingon the Key Builders folder of the NFC UI navigation tree displays a table of currently defined
keybuilders as shown in Figure 2-10. Click Edit to modify a specific key builder,or Remove to remove
aselected key builder. Click Add Key Builder to bring up an empty form for defining a newkey builder.
