The HP OpenView Network Node Manager (NNM) consists of two main
parts: HP OpenView Windows (ovw) and the HP OpenView SNMP Event
System.
The HP OpenView Windows API supports the creation and
manipulation of maps, submaps and symbols, and allows the generation
of dialogs for user interaction. It is intended for the development of
applications that need to use these features. New symbols can also be
registered by ASCII Symbol Registration Files.
The HP OpenView Windows API also supports access to the HP
OpenView Windows object database which stores information about
network objects. An object is an internal representation of a logical or
physical entity or resource that exists somewhere in a computer
network. Objects have certain fields which can be seen as the attributes
of an object, for example an object representing a computer in a network
will have fields for the name and the IP address of that node. New fields
can be added to objects by either using the HP OpenView Windows API
or Field Registration Files.
The HP OpenView SNMP Event System provides a command and a
programmer's interface to SNMP communication functions, an API for
SNMP configuration purposes and it stores information about the
network topology in a topology database.
