Cisco Systems OL-11399-01 manual Aggregation Schemes, Sum with Sampling Estimation

Chapter 2 Using the NetFlow Collector User Interface

Configuration

Sum with Sampling Estimation

The Sum with Sampling Estimation value builder obtains an integer value from a field in a flow, multiplies by the sampling rate in effect, and adds the estimate to a count. If not used with V9 export, the value is not scaled because the sampling rate is not known. It has the following attributes.

Attribute	Description
Name	Column name in output.
Field	ID of the integer field to obtain from a flow.
Sampling Interval Builder ID	Always use the default value.
Allow null value	If not selected and the flow does not contain the
	specified field, an error is logged.

Aggregation Schemes

Aggregation schemes define the set of keys and values used for aggregation and that appear in the Cisco NetFlow Collector output files. Clicking on the Aggregation Schemes folder of the navigation tree displays a table of all existing aggregation schemes, as shown in Figure 2-13. Click on the appropriate link to modify or remove an aggregation scheme. Click on Add Aggregation Scheme to bring up an empty form for defining a new aggregation scheme.

Figure 2-13 Aggregation Schemes

The Add Aggregation Scheme and Modify Aggregation Scheme in windows, as shown in Figure 2-14, are identical with the exception that you cannot change the Aggregation Scheme ID on the Modify Aggregation Scheme window. Use this form to select key and value fields and click Add or Modify respectively to complete the operation. From the Modify Aggregation Scheme window you can also remove the currently displayed aggregation scheme.
