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 purposes. Accounting consists of  record-
     ing 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  ele-
     ment  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 informa-
     tion), 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  avail-
     able through kstat:

       module: flowacct                   instance: 
         name: Flowacct statistics        class 
               bytesintbl               
               epackets                   
               flowsintbl               
               nbytes                     
               npackets                   
               usedmem
