A metric is an individual piece of information that Foglight for Oracle collects about the performance of a system. The information may be a numeric value (a number or percentage), a string of text, or some other piece of data.
Every time the Foglight for Oracle dashboard is refreshed, the cartridge retrieves the latest value of the metric, which can then be displayed in a drilldown or on the home page.

Online Transaction Processing. OLTP allows real-time processing of SQL transactions, in order to support Customer Relationship Management (CRM), ERP, and other time-critical applications. OLTP is characterized by high rates of index lookups, single row modifications, and frequent commits.
Because real-time transaction processing is being increasingly carried out on a network and may include more than one company, OLTP databases use client/server processing and allow transactions to run on different platforms in a network.
