An Introduction to Integrating Partner Applications with VPO

Why Integrate with VPO?

Chapter 1 29

In addition to the standard functionality of VPO, the Developer’s Toolkit

provides a powerful C-library of Application Programming

Interfaces (APIs), including:

❏ Operator APIs to operate on VPO messages, message events, and

applications responses, for example to own or disown a message.

Interface API to access VPO by opening an instance to the following

interfaces:

• Server Message Stream Interface

• Agent Message Stream Interface

• Legacy Link Interface

• Application Response Interface

• Message Event Interface

❏ Conﬁguration APIs to conﬁgure VPO data directly in the database.

The functions allow you, for example, to conﬁgure new VPO

templates or managed nodes, or to modify existing applications or

users. In addition, functions are available to control access to VPO

data, and to distribute conﬁguration changes to the managed nodes.

For more information about the VPO User APIs, see Chapter 4, “Using

the VPO Application Programming Interfaces,” on page 163.

The OpenView Windows API and SNMP API of Network Node Manager

are also available for use in generating an integrated solution. For

information on these APIs, see Chapter 6, “Integration Facilities of the

HP OpenView NNM Core Platform,” on page 227.
