Designing and Managing Behavior Models
-
Behavior Models and Their Components - NerveCenter Objects - Nodes -
In NerveCenter terminology, a node is either a workstation or a network device such as a router. NerveCenter monitors and manages a set of nodes, and each behavior model manages a subset of those nodes.

A node object has the following data set.
The following table explains what information these data members contain and, where appropriate, how NerveCenter uses that information.
Definitions of Node Attributes
| Node Attribute | Definition |
|---|---|
Contains the name of the workstation or network device. The name can be a hostname or an IP address. | |
Contains the community name that NerveCenter will include in any SNMP GetRequest or GetNextRequest it sends to the agent on this node. By default, set to public. | |
Contains the community name that NerveCenter will include in any SNMP SetRequest it sends to the agent on this node. By default, set to public. | |
Contains the node's property group. This property group helps determine whether a particular poll will query this node and whether a particular alarm will be instantiated for the node. For further information about property groups, see the section Property Groups and Properties. | |
Contains the number of the port that the node's agent uses to receive SNMP messages. By default, the port is set to 161. | |
Contains the node's IP address. If the node is multihomed, IP Address List can contain a list of addresses. | |
Boolean. Indicates whether NerveCenter is to manage the node. By default, NerveCenter manages all nodes it or a network management platform discovers. However, you can mark a node as unmanaged if you do not want it to be affected by any NerveCenter behavior models. | |
Boolean. Used when NerveCenter is integrated with a network management platform. If a node is removed from the platform's database, NerveCenter removes the node from its database if this attribute is set. | |
Boolean. Indicates whether a network management platform discovered the node. | |
Boolean. Indicates that the node is in a suppressed state. Suppressing a node limits polling because if the node is suppressed and a related poll is suppressible, that poll cannot cause an SNMP GetRequest to be sent to the node. |
