Class Machine (OS server)

Description

Machine is the main entity of the system layer of the Configuration database. It records servers and other intengible items that are defined by operating system, not by a physical device.

ObjectGears Configuration database contains the entity Machine (OS server) which is determined for servers in the intangible meaning and differentiates them from objects recorded in the class Device (Hardware layer). When we start with Configuration database, properties of the both entities may coincide to us. Therefore, you may have in a table with list of servers properties like server name, IP address, operating system, windows domain and together with them also manufacturer, hardware model, serial number, year of production, support end date, inventory number and server location (position in rack, building, location).

It is useful to separate both categories and better differentiate the server concept. In case of a physical object let`s speak about Device, which has associated properties like manufacturer, model, serial number or inventory number. Server, which has usually an operating system as a key property, will be called Machine (OS server). In the class Machine we are going to keep records of not only physical (native) and virtual servers, but also server farms, clusters, cluster services and other entities.

Automated data import

This entity can be filled in automatically by means of infrastructure function OG_Servers.
