Scaling guidelines for statistics collection
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.
