Configuring the AppFlow Feature

You configure AppFlow in the same manner as most other policy-based features. First, you enable the AppFlow feature. Then you specify the collectors to which the flow records are sent. After that, you define actions, which are sets of configured collectors. Then you configure one or more policies and associate a action to each policy. The policy tells the NetScaler appliance to select requests the flow records of which are sent to the associated action. Finally, you bind each policy either globally or to a specific vservers to put it into effect.

You can further set AppFlow parameters to specify the template refresh interval and to enable the exporting of httpURL, httpCookie, and httpReferer information. On each collector, you must specify the NetScaler IP address as the address of the exporter.

Note: For information about configuring the NetScaler as an exporter on the collector, see the documentation for the specific collector.

The configuration utility provides tools that help users define the policies and actions that determine exactly how the NetScaler appliance export records for a particular flow to a set of collectors(action.) The NetScaler command line provides a corresponding set of CLI-based commands for experienced users who prefer a command line.
