Alcatel-Lucent 5620 Service Aware Manager, Release 7.0 R6 December 2009 66-5

Accounting statistics

Accounting statistics counters typically record service or subscriber usage data for

billing or to ensure SLA compliance. See the appendices for a complete list of the

available accounting statistics.

Accounting policies define the schedules that NEs use for the regular collection of

accounting statistics. File policies specify how NEs store the accounting statistics

data. An NE performs scheduled accounting statistics collection after a file policy

and an accounting policy are deployed to the NE.

The 5620 SAM uses FTP or SCP to collect the accounting statistics files stored on

NEs. See the appropriate device documentation for more information about

accounting file storage on the device.

The supported accounting statistics types are:

• service accounting statistics—collected on every queue on every SAP that is

linked to an accounting policy. Service accounting statistics provide queue

throughput and drop information, and can be used for billing and SLA purposes.

• network accounting statistics—collected on every queue on every SDP, or

collected on network ports that are linked to an accounting policy. Network

accounting statistics measure forwarding class queue usage. This information is

used to monitor link utilization, and to identify network traffic patterns and

trends, for capacity planning and traffic engineering.

• subscriber accounting statistics—collected on a subscriber profile for residential

subscriber instances. Subscriber accounting statistics are used for billing and SLA

purposes.

• application assurance, or AA, accounting statistics—collected on applications,

application groups, and protocols. See the 5620 SAM User Guide for more

information about AA accounting statistics.

You can customize the statistics record in a service, subscriber, or AA accounting

policy by specifying the counters that are collected and the data thresholds for

collection. See chapter 69 for more information about custom accounting records.

Accounting statistics are stored in the 5620 SAM database and can be exported using

the 5620 SAM-O interface. The length of time that the 5620 SAM database stores

accounting statistics is specified during 5620 SAM database installation. You can

also change this retention period after installation. See chapter 18 of the 5620 SAM

User Guide for more information.

You can view historical and real-time accounting statistics in tabular or graphical

form using the 5620 SAM client GUI.

Note — SDP statistics collection is supported only on devices that are

in chassis mode B, C, or D. See the appropriate device documentation

for more information about configuring the chassis mode.
