Using OpenView as a node source

NerveCenter can integrate with HP OpenView Network Node Manager by receiving information about some or all of the nodes managed by OpenView.

NerveCenter can obtain node information from any or all of the following sources:

• A network management platform, such as HP OpenView Network Node Manager or IBM NetView for AIX
• The NerveCenter Discovery behavior model
• An administrator's manual entries

  Note    Though NerveCenter supports SNMP v1, v2c, and v3, when NerveCenter obtains its nodes from a platform, the platform does not provide SNMP version information. By default, NerveCenter deems the SNMP agents on these nodes to be SNMP v1 by default.
  
  If you want NerveCenter to attempt SNMP version classification automatically for the nodes it receives from your platform, you must enable auto-classification. Then, NerveCenter can classify the correct SNMP version for each node with each resynchronization. Refer to Managing NerveCenter for more information about SNMP auto-classification.

  Note    If you want NerveCenter to manage SNMP v3 nodes, you must use NerveCenter as your trap source regardless of the node source you configure. Refer to Managing NerveCenter for more information about the SNMP trap source.

When NerveCenter uses information obtained by a network management platform, it does not use the platform's database as its repository for managed nodes. Instead, it stores node information in its own database in a node list.

There are several reasons for NerveCenter maintaining a node list in its own database:

• There may be a considerable distance between the platform's database and NerveCenter, making frequent access time-consuming and costly.
• NerveCenter adds configuration data to the node data that the management platform does not necessarily provided.
• Administrators have the option of adding nodes not in the platform's node database to the node list in NerveCenter's database.

Using OpenView as a node data source involves the following three items:

• Setting filters that limit the nodes NerveCenter monitors.
