NAME

6       flowacct - Flow Accouting module
7

DESCRIPTION

9       The flow accounting module flowacct enables you to record flow details.
10       You use flow details to gather statistics and/or for billing  purposes.
11       Accounting  consists of recording flow details in a location you desig‐
12       nate and in a format that you can retrieve  at  a  later  stage.  IPQoS
13       accounting  relies  on  the exacct mechanism to store and retrieve flow
14       information.
15
16
17       A flow is defined by the 5-tuple - saddr, sport, daddr, dport and  pro‐
18       tocol.
19
20
21       Typically,  the  accounting  module  is  the last datapath element in a
22       sequence of actions. Flow attributes include ToS/DS, user  id,  project
23       id, creation time (time the flow was created), last seen (when pkts for
24       the flow were last seen), action name (instance that recorded the  flow
25       information),  nbytes  and  npackets.  Attributes are split into groups
26       entitled basic and extended. The basic group records only  the  nbytes,
27       npackets and action name, while the extended group is a superset of the
28       basic group and records all attributes. The attributes to be  recorded,
29       in  addition  to  the  accounting  file that contains flow details, are
30       selected using acctadm(1M). The flowacct  module  does  not  provide  a
31       mechanism  to retrieve flow information from the accounting file nor to
32       interpret the retrieved information.

STATISTICS

35       The flowacct module exports the following statistics available  through
36       kstat:
37
38         module: flowacct                   instance: <action id>
39           name: Flowacct statistics        class <action name>
40                 bytes_in_tbl               <bytes in the flow table>
41                 epackets                   <packets in error>
42                 flows_in_tbl               <flow records in the flow table>
43                 nbytes                     <number of bytes through this instance>
44                 npackets                   <number of packets>
45                 usedmem                    <memory, in bytes, used by the flow table>
