Open the NSP Flow Collector web UI. The Collection Policy page is displayed.

Click on the Aggregation Policy tab.

Perform one of the following:

1. If the NSP Flow Collector is to collect system Cflowd statistics, select the required aggregation types from the tabs in the lower panel.

2. If the NSP Flow Collector is to collect AA statistics, select one or more statistics classes in the Subscriber Collection panel to enable aggregation for the classes.

Use the Interval drop-down menus in the Aggregation Intervals panel to specify the aggregation interval for each statistic type, as required.

Note: The statistics collection interval affects NSP Flow Collector performance. A larger interval results in proportionally larger files, which take longer to store and transfer.

Note: For CGNAT statistics, you must set the collection interval no higher than the following, based on the expected flow rate:

• 350 000 flows/s—1 minute

• 50 000 flows/s—5 minutes

• 25 000 flows/s—15 minutes

The Interval Closing Timeout parameter specifies a latency value that is applied at the end of a collection interval to ensure that any queued statistics are written to the current file. Typically, the default value of one second is adequate; configure the parameter only at the request of technical support.

Specify the aggregations for each statistic type, as required.

1. Click on the tab in the lower panel that corresponds to the statistic type.

2. Select or deselect aggregations, as required.

Click Save Configuration. The configuration is saved.
