NAME
flowacct - Flow Accouting module
DESCRIPTION
The flow accounting module flowacct enables you to record
flow details. You use flow details to gather statisticsand/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 includeToS/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 selectedusing acctadm(1M). The flowacct module does not provide a
mechanism to retrieve flow information from the accounting file nor to interpret the retrieved information. StatisticsThe flowacct module exports the following statistics avail-
