Overview

The Adva Optical Metro Ethernet Technology Pack provides SNMP collection formulas specific to the associated network devices and technologies on which it operates. These SNMP collection formulas are installed with the Adva Optical Metro Ethernet Technology Pack.

Data Collection

This technology pack uses SNMP collection to gather data about Adva Optical Metro Ethernet devices and services. With SNMP collection, data is gathered from objects in standard and vendor-specific MIBs.

Formulas and Metrics

After the network data is collected, Netcool/Proviso processes the data and generates the metrics that are stored in the DataMart database and used in DataView reports. This processing is performed by the formulas described in this chapter.

A metric has the same name as the formula that generates it.

Metrics are categorized according to the type of process used to calculate the metric, as follows:

•SNMP — Data collected from MIB objects and processed by formulas included with this technology pack. Formulas that generate SNMP metrics are listed in this chapter in the Syntax section of the reference pages.

•Generic — A metric whose database location is mapped to multiple formulas. This allows the formulas to store the metrics they generate against a single database ID, allowing the metrics to appear in a single DataView report.

•CME — Metrics that are produced by calculations that the Netcool/Proviso Complex Metric Engine (CME) performs, using other metrics and sub-element properties as inputs.
