Objects

Overview

All network infrastructure monitored by NetXMS inside monitoring system represented as a set of objects. Each object represents one physical or logical entity (like host or network interface), or group of them. Objects organized into hierarchical structure. There are 12 different object classes:

Entire Network	Abstract object representing root of IP topology tree. All subnet objects located under it. System can have only one object of this class.
Subnet	Object representing IP subnet. Typically objects of this class created automatically by the system to reflect system's knowledge of IP topology.
Node	Object representing physical host or network device. These objects can be created either manually by administrator or automatically during network discovery process.
Cluster	Object representing cluster consisted of two or more hosts.
Interface	Object representing network interface of node. These objects created automatically by the system during configuration polls.
Network Service	Object representing network service running on a node (like http or ssh).
VPN Connector	Object representing VPN tunnel endpoint. Such objects can be created to add VPN tunnels to network topology known y NetXMS server.
Service Root	Abstract object representing root of your service tree. System can have only one object of this class.
Container	Grouping object which can contain nodes, subnets, clusters, conditions, or other containers. With help of container objects you can build object's tree which represents logical hierarchy of IT services in your organization.
Condition	Object representing complicated condition – like "cpu on node1 is overloaded and node2 is down for more than 10 minutes".
Template Root	Abstract object representing root of your template tree.
Template Group	Grouping object which can contain templates or other template groups.
Template	Data collection template. See Data Collection section for more information about templates.

Every object has set of attributes; some of them are common (like id and name), while other depends on object class – for example, attribute "SNMP community string" have only node objects.

Top Level Objects

NetXMS has three top level objects – Entire Network, Service Root, and Template Root. These objects served as an abstract root for appropriate object tree. The following table represents possible child object classes for top level objects:

Object	Possible childs
Entire Network	Subnet
Service Root	* Container Subnet Node Cluster Condition
Template Root	* Template Group Template

All top level objects has only one editable attribute – object's name.
