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:
