Scaling guidelines for statistics collection

Statistics collection

5620 SAM provides the ability to collect statistics information from the network

elements. This section provides guidelines that can be used to determine the extent to

which Statistics Collection can be retrieved from the network.

Statistics collection definitions

Performance statistics: These statistics are associated with various network objects such

as ports, interfaces, channels and network elements (routers). These statistics are retrieved

by 5620 SAM using SNMP polling according to the MIB policies that are configured by

the user.

Accounting statistics: These statistics are associated with Services, Subscribers, and

Network Interfaces and contain data that can be used for accounting, billing and SLA

management purposes. These statistics are collected on the 7x50 and retrieved by 5620

SAM via a file that is transferred via ftp/sftp.

Application Assurance Accounting statistics: These statistics are associated with

Subscribers, SAPs, and spoke SDP bindings and contain data related to traffic flows that

can be used for QoS and traffic management, and application aware reporting. These

statistics are collected on the 7x50 ISA cards and retrieved by 5620 SAM via a file that is

transferred via ftp/sftp.

Statistics Item: An individual statistics counter, such as RxOctets or TxFrames.

Statistics Record: A collection of statistics items which is retrieved from the router and

stored in the 5620 SAM database as an atomic operations. In the various statistics forms

on the 5620 SAM GUI Client, a statistics record appears to the user as a single row which

contains the collection or retrieval timestamp and a set of individual statistics items. In

the case of performance statistics, a statistics record corresponds to a row in the MIB

table.

Determining the number of statistics records that will be collected

Statistics can be collected and processed by the 5620 SAM Server or by the 5620 SAM

Auxiliary Statistics Collector for dedicated statistics handling. The 5620 SAM Auxiliary

Statistics Collector provides a dedicated workstation for statistics collection. The

following sections should be used to determine the maximum performance and

accounting statistics for different hardware setups.
