12 — Statistics collection and plotting
12.1

Statistics collection and plotting overview

The 5620 SAM performs on-demand or scheduled statistics collection for managed
NEs, services, or virtual network objects. These statistics can be used to monitor or
troubleshoot a data centers network, or to perform SLA or billing functions. Statistics
collection can be configured with policies that are distributed to specified network
objects. Statistics are displayed in tabular or graphical form using the statistics
plotter.
12.2

Statistics collection

The 5620 SAM collects network performance statistics by polling network element
MIB tables using SNMP. Performance statistics provide information about physical
equipment, routing, and other NE properties. MIB statistics collection policies define
performance statistics collection at the NE level or the network object level. The
5620 SAM supports the collection of some statistics counters from standard system,
interface, and routing MIBs on generic NEs.
The 5620 SAM collects accounting statistics to gather throughput information for
queues that are associated with SAPs, network ports, and subscriber profiles.
Accounting statistics policies can be defined for V-Ports to monitor service, network,
or subscriber accounting statistics. The 5620 SAM uses FTP or SFTP to collect
MIB-based accounting statistics from NEs. Queue filters can specify which queues
are processed by the statistics collector and which are ignored.
The 5620 SAM collects server performance statistics to monitor 5620 SAM system
functions and processes. Server performance statistics are collected from internal
5620 SAM data, such as memory usage and alarm counters.
BGP statistics can be collected and monitored using functionality from the
5650 CPAM. Network BGP statistics are collected by the 7701 CPAA and retrieved
by the 5650 CPAM. MIB statistics policies can be applied to the 7701 CPAA to
define the collection of specified statistics counters. BGP statistics can be plotted and
stored using the statistics plotter. The 5650 CPAM has BGP-specific threshold
crossing alarms which are raised by the 7701 CPAA when specified thresholds are
reached.
Collected statistics are stored in the 5620 SAM database and are retained for a
specified duration. Statistics data can be backed up and recalled from the database.
See the 5620 SAM Statistics Management Guide for more information on statistics
collection.
