Chapter 8:  Discovery Formulas 
This chapter discusses the following topics: 
Overview 
A discovery formula (also called an inventory formula) allows Netcool/Proviso to recognize resources specific 
to the target devices and technologies supported in the Adva Optical Metro Ethernet environment so that 
information can then be collected on those resources. A discovery formula runs during the inventory process - 
the process of discovering and analyzing the network. Discovery formulas for some network interfaces and 
devices (for example, Frame Relay) are already included with Netcool/Proviso DataMart. 
The Adva Optical Metro Ethernet Technology Pack provides discovery formulas specific to the devices and 
technologies that operate in the Adva Optical Metro Ethernet environment. This user guide discusses the 
discovery formulas that the Adva Optical Metro Ethernet Technology Pack provides. 
Netcool/Proviso Discovery Formula Tree 
The Adva Optical Metro Ethernet Technology Pack provides a formula tree where the SNMP discovery formulas 
are defined in the Netcool/Proviso database. On the following pages, the path that is defined for each formula 
reflects that formula’s location in the formula tree. You can access this directory using the Netcool/Proviso 
DataMart Formula Selector. See the Netcool/Proviso DataMart Configuration Guide
 
for more information.
Discovery Formula Structure 
A discovery formula typically has three sections:
Instance variable declaration. Instance variables represent the input values for a formula. The following 
line is an example of an instance variable declaration:
