Chapter 7: SNMP Collection Formulas

Note: Generic and CME formulas may not be included in this technology pack.

Metrics may appear in DataView reports as raw data, or they may be further processed by the Complex Metric Engine — for example, to produce data aggregations over time. To learn where the metrics generated by the formulas in this chapter are used, see the chapter on supported reports in this guide.

This chapter is a reference of the formulas that the Adva Optical Metro Ethernet Technology Pack provides. The chapter lists formulas alphabetically.

Formula Reference

The following pages provide a reference of the formulas that this technology pack provides. The reference pages have the following sections:

•Type. The source of data for the formula being described — for example, SNMP (collect).

•Description. The description of the formula.•Syntax. The formula that generates the metric from the collected SNMP data.

After this formula processes the data, the resulting metric can be used in Netcool/Proviso DataView reports and in calculations of other metrics.

See the Netcool/Proviso SNMP Formula Language Guide for detailed information about the syntax used to write SNMP collection formulas.

•Formula Input. This section appears with CME formulas only. It shows the variables that the CME formula uses as input, and the property or formula that supplies a variable’s value. In the following example, the formula Egress Octets Forwarded is the source of the value of the input variable EgressOct:

Input: EgressOctSource: Egress Octets Forwarded (Formula)

•Generic Database Alias. A database location where the metric generated by a formula can be stored.

Typically, generic metrics serve as repositories in the database for mixed data collected from a particular kind of sub-element — for example, low- and high-capacity interfaces. Storing mixed data against a generic metric ID allows you to display the different kinds of data in a single report.

•Path. The path where the referenced SNMP collection formula is defined in the Netcool/Proviso database.

You view the formula tree through the Formula Selector dialog of the Netcool/Proviso Formula Editor. To display this dialog, click File > Load in the Formula Editor.

•MIB. One or more MIBs that supply data to the referenced SNMP formula.
