66 — Statistics overview

Alcatel-Lucent 5620 Service Aware Manager, Release 7.0 R6 December 2009 66-7

3HE 04551 AAAE Ed. 01 Statistics Management Guide

Real-time statistics collection and graphical display is supported for many network

and service objects. A 5620 SAM client can open up to five real-time plotter

windows, and each window can display up to four counters. If multiple open

statistics plotters point to the same NE or the same object on an NE, the NE receives

a large number of SNMP requests. Alcatel-Lucent recommends that you limit the

number of open statistics plotters for the same NE. You can use a span of control to

limit operator access to specific NEs and thereby reduce the number of simultaneous

real-time collections from a specific NE.

Accounting statistics

If you need to collect large numbers of accounting statistics, for example, more than

one million, Alcatel-Lucent recommends that you enable the statistics collection in

a staggered manner. This helps to prevent the first-time collection delays associated

with building the initial cache. For example, if you need to collect 6 million statistics

in a 15–min interval, enable 500 000 statistics and wait until the interval completes

before you add the next 500 000 statistics, and so on.

You can use custom accounting records to limit the processing requirements of

service, subscriber, or AA accounting statistics collection. See chapter 69 for more

information about custom accounting records.

The 5620 SAM uses FTP or SCP to retrieve an NE statistics file when the NE notifies

the 5620 SAM of the new file. The 5620 SAM retrieves and processes the files in the

order that it receives the notifications. An NE retains files only for the period

specified in the file policy; after this period, the NE deletes the files. The statistics

data in the files is lost if the files are not retrieved from the NE during this time.

When an accounting statistics counter is not supported by an NE or is excluded from

collection using a custom record, the counter value is not included in a statistics

record or displayed in the 5620 SAM client GUI.

Performance statistics

If any performance statistics remain to be collected at the end of a collection interval,

they are skipped and the next collection begins. This results in lost statistics because

the collection interval is too short.

66.4 5620 SAM statistics and OSS applications

The 5620 SAM can provide some or all collected statistics to OSS applications using

the 5620 SAM-O interface. See chapter 74 for information about using the

5620 SAM-O interface to retrieve statistics data from the 5620 SAM.

Note — The 5620 SAM limits the number of active MIB-based

accounting statistics plots per NE to four among all 5620 SAM

clients. For example, when two 5620 SAM clients each have two

active MIB-based accounting statistics plots associated with the same

NE, no other client can open a plot of the same type for the NE.

Note — After an extended loss of connectivity to an NE that has an

active accounting policy, the 5620 SAM resumes accounting

statistics file retrieval by starting with the most recent statistics file.
