Chapter 10. Modifying the collection strategy

Describes how to modify the amount of data that is managed by the Alcatel-Lucent

5620 SAM LogToFile Technology Pack. You can modify by changing the types of

data that are collected, or by changing the collection period for the SAM statistics,

or both.

Specifying what inventory and metrics to collect

The types of inventory and metrics that must be collected from SAM server is

specified in the configuration files. These configuration files are found on the

DataStage server. The configuration files specify which inventory class and metrics

classes must be requested from the SAM server. The SAM server then creates the

necessary files that are received by DataStage.

About this task

There are three different configuration items:

Filter Drops the records.

Partition

Enables multiple UBAs.

Window

Handles different periods. For example, 5, 15.

Filter:

The name of the filter file is filter_lookup.csv, and has the configuration level as

User. No match for this file is not available.

Fields Steps to get the information

Class name Name of the SAM Class. For metric classes,

use <class name>LogRecord names.

Expression Set it as '1' (TRUE) if no filter is needed.

The Expression field accepts full blown Perl expressions with special variables

enclosed with '{}' to refer to attributes within the class. There is a special

'{DEFAULT}' to refer to the partition key attribute of the class.

For example, equipment.PhysicalPort,{DEFAULT} eq "1.1.1.1"

This expression means that the DataStage filter allows only the

equipment.PhysicalPort class objects that have "1.1.1.1" value for its siteId.

equipment.PhysicalPort,{cardSlotId} != 2

This expression means that the DataStage filter allows only the

equipment.PhysicalPort class objects other than the card slot id of 2.

equipment.PhysicalPort,{DEFAULT} eq "1.1.1.1" && {cardSlotId} != 2 logical

operator is supported.

equipment.PhysicalPort,{DEFAULT} =~ /^1.1/ Regular expression is supported. It

allows site key that starts with "1.1".equipment.PhysicalPort,0
