Netcool/Proviso Adva Optical Metro Ethernet 2.1.1.0 Technology Pack User’s Guide, Version 4.3-X 109
Chapter 7: SNMP Collection Formulas
This chapter discusses the following topics:
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.
