-System load

-Login sessions

-Modem availability

HP OpenView Network Node Manager

HP OpenView Network Node Manager (NNM) and Network Node Manager Extended Topology together provide your management team with the capabilities that you need to address your key business and network challenges:

A new approach to root-cause analysis that includes a set of easy-to-use tools to help you identify and resolve conditions before they become problems.

ID for Networks delivers advanced capabilities for network event reduction, root-cause analysis and a new management concept called State Analysis, which actively determines the health of network protocols and complex network configurations.

Includes out-of-the-box correlators for enhanced root-cause analysis and the new Correlation Composer to easily tailor the out-of-the-box correlators that are shipped with Network Node Manager to fit your particular needs.

The NNM serves as a SNMP manager, trap collector, and connectivity tester. It also acts as a framework for the attachment of other programs, such as Avaya Network Management Console with VoIP SystemView.

Topology discovery visually shows the interconnection of routers, switches, and endpoints.

Network management models

There are two basic network management models:

Distributed — specialized, nonintegrated tools, and sometimes organizations, to manage discrete components.

Centralized — integrated network management tools and organizations for a more coherent management strategy.
