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. |
