User`s guide

An attribute is the name of a variable (metric) that is defined for a model type and whose values are assigned or

measured for the models of that model type. The attributes for each model type are controlled by that model type’s

Management Module. For example, some of the attributes for Cabletron MRXI repeaters are Model_handle (model id),

Model_type_handle (model type id), and IP_In_Discards (the number of IP layer packets discarded). Thus, a

SPECTRUM database generally has data about more than one attribute per model and, for all models of the same model

type, has data on the same attributes.

An attribute ID (attrid) is a hex number that uniquely identifies that particular attribute. Attribute IDs are assigned by

SPECTRUM. For example, Model_type_handle is attribute ID 0x10001, IP_In_Discards is attribute ID 0x1009d, and so

on.

Note: The variable names in the IT Service Vision performance data warehouse are the same as the SPECTRUM

attribute names (or shortened if the attribute names are too long).

In this document, the following terms refer to the Spectrum software:

SpectroSERVER is the name of the SPECTRUM server software. It consists of the knowledge base server and a set of

background processes (daemons).

SPECTRUM_home (also called SPECTRUM_path or SPECTRUM_top) is the directory in which the SPECTRUM server

software is installed. A typical value for SPECTRUM_path is /usr/spectrum

SpectroGRAPH is the name of the SPECTRUM client software.

SPECTRUM Data Export (SDE) software is a tool that exports SPECTRUM data into SAS data sets (or ASCII files).

SPECTRUM refers to the following:

SpectroSERVER

SpectroGRAPH

SPECTRUM Data Export (SDE)

other applications and tools that these three products use.
