NAME

       flowacct - Flow Accouting module

DESCRIPTION

       The  flow  accounting module flowacct enables you to record flow details. You use flow details to gather statistics and/or for billing pur-
       poses. Accounting consists of recording flow details in a location you designate and in a format that you can retrieve at  a  later  stage.
       IPQoS accounting relies on the exacct mechanism to store and retrieve flow information.

       A flow is defined by the 5-tuple - saddr, sport, daddr, dport and protocol.

       Typically,  the	accounting  module is the last datapath element in a sequence of actions. Flow attributes include ToS/DS, user id, project
       id, creation time (time the flow was created), last seen (when pkts for the flow were last seen), action name (instance that  recorded  the
       flow  information),  nbytes  and  npackets.  Attributes are split into groups entitled basic and extended. The basic group records only the
       nbytes, npackets and action name, while the extended group is a superset of the basic group and records all attributes. The  attributes	to
       be  recorded,  in  addition to the accounting file that contains flow details, are selected using acctadm(1M). The flowacct module does not
       provide a mechanism to retrieve flow information from the accounting file nor to interpret the retrieved information.

STATISTICS

       The flowacct module exports the following statistics available through kstat:

	 module: flowacct		    instance: <action id>
	   name: Flowacct statistics	    class <action name>
		 bytes_in_tbl		    <bytes in the flow table>
		 epackets		    <packets in error>
		 flows_in_tbl		    <flow records in the flow table>
		 nbytes 		    <number of bytes through this instance>
		 npackets		    <number of packets>
		 usedmem		    <memory, in bytes, used by the flow table>
