Introduction to HP OpenView

Service Assurance for

Communication Networks

HP OpenView Service Assurance for Communication Networks

(OVSACN) is an integrated solution for managing IP devices, telecom

equipment, system information, and software applications. It is based on

the HP OpenView Operations (OVO) platform, including HP OpenView

Network Node Manager (NNM), and is designed for the communications

service provider.

OVSACN manages events from multi-vendor telecom equipment using a

variety of network transport protocols including ASCII, CMIP, SNMP,

and TL/1. OVSACN consolidates the events into problems and presents

them in a single problem report format.

OVSACN combines messages from all managed devices and applications

into one message browser. Network operators see the broad picture of the

network state and can prioritize effort based on the greatest need for the

entire network.

OVSACN consists of three purchasable products: HP OpenView

Operations (OVO), OV Telecom Extensions for OV Operations, and OV

Topology Server.

HP OpenView Operations includes the OVO GUI, the main GUI used to

manage assigned nodes, applications, messages, and services. The OVO

GUI presents the network health in graphical and tabular displays, and

shows status for the represented elements based on the severity of the

received messages.

The optional OV Topology Server displays a map of telecom devices and

displays telecom problems in the topology GUI. It receives all incoming

messages generated by equipment included in the topology and

associates each message with a particular managed object instance. The

OV Topology Server sets the status for each managed object instance

according to the statuses contained in the received messages. It also

formats all received messages into problems and displays them in a

problems presenter.

HP OpenView Operations

The primary components of OVO are:

• OVO Agent—The OVO agent processes run on managed nodes

throughout the environment to collect messages from the processes

running on those nodes. The OVO agent filters and formats these

messages according to information in configured message source

templates. It then forwards relevant information in the form of OVO

messages to the OVO server. The OVO server responds with actions to

prevent or correct problems on the managed nodes and passes the

messages to the message browser in the OVO operator GUI.

The OVO agent on the OVO server machine receives new problem

and status messages from the OV Topology Server. The OVO agent

formats these messages and forwards them to the OVO server. This

OVO agent also performs self-management by reading OVO server

software and machine operating system log files and creating and

sending applicable messages to the OVO server.

• OVO server—The OVO server receives formatted messages from all

managed nodes. It manages these messages, initiating automatic

actions as necessary, and groups messages according to the current

configuration. The OVO server updates the messages and status

information displayed in the OVO GUI. Additionally, the OVO server

can forward messages to other management servers and can install,

configure, and update the OVO agent software on managed nodes.

• OVO GUI—The OVO GUI displays the managed nodes in the node

bank. This node bank includes the topology of the managed telecom

network elements. The OVO GUI also includes message groups,

applications, and services. The OVO GUI message browser displays

formatted messages received from all managed devices and

applications. Problems displayed in the message browser also appear

in the optional topology GUI’s problems presenters.

The network operators interact with the information presented in the

OVO GUI to know the condition of the managed nodes they are

responsible to maintain and to set priorities for their work day.

• Service Navigator—Service Navigator is an optional add-on

product to the OVO Telecom Agent that provides visual data about

the availability of the services in the network. Service Navigator

displays a hierarchy of services and shows the current status of each

service. It defines relationships between these services and managed

devices and applications, so that an incoming message from a device

or application can affect the status of an associated service. Service

Navigator provides root cause analysis of service status issues. It can

also show the services impacted by a particular failure condition

listed in the message browser. When the OV Topology Server is also

configured, the service hierarchy can show the specific telecom

network element that is causing a service degradation.

OV Telecom Extensions for OV Operations

The primary components of the OV Telecom Extensions for OV

Operations product are:

• Telecom subagent—The telecom subagent acts as a data collector to

receive messages from telecom network elements and telecom

element management systems. The telecom subagent formats the

received messages using the configured message source templates.

Additionally, the telecom subagent provides table lookup and time

arithmetic capabilities. If the OV Topology Server is configured, the

telecom subagent formats the messages into X.733 alarm format and

forwards them to the topology server for further processing. If the OV

Topology Server is not configured, the telecom subagent forwards the

messages to the OVO agent.

• Topology adaptor—The topology adaptor forwards problem

notifications from the topology server to the OVO agent for inclusion

in the message browser. It maps source topology elements to nodes in

the OVO GUI node bank for maintaining the two GUIs. The topology

adaptor also maintains the synchronization between the message

browser and the problems presenter by sending messages directly to

the OVO server. This synchronization includes changes to problem

ownership, severity, acknowledged state, and discharged state. When

Service Navigator is configured, the topology adaptor assigns

messages to the applicable services and communicates this

information to the OVO server so the status of services that include

elements in the telecom topology stays current.

OV Topology Server

The primary components of the OV Topology Server product are:

• Topology server—The topology server receives messages from the

telecom subagent and correlates them into problems. The topology

server acts as a server to the topology GUI by updating the problems

and status information displayed in the topology GUI.

• Topology GUI—The topology GUI consists of several presenters,

including the map presenter and the problems presenter. The map

presenter displays a hierarchical view (server maps that display

containment) or logical view (map of managed services) of the telecom

network objects in the map presenter. The problems presenter

displays formatted problems correlated from incoming topology

events. These problems are also displayed in the OVO operator GUI’s

message browser.

The network operators interact with the information displayed in the

topology GUI to monitor the condition of the managed objects for

which they are responsible and to set priorities for their work day.

Using HP OpenView Operations Features

When used together, the OVO GUI and the topology GUI are powerful

tools for managing your entire network. You can select a message in the

OVO GUI and launch a presenter in the topology GUI to view further

information about the selected message. This cross-launching

functionality provides convenient access to a deeper level of information

without requiring separate logins to each GUI.

The OVO GUI window is divided into two main areas; the scoping area

on the left and the client area on the right. When you start OVO the

Active Messages browser is displayed in the client area. This is a view of

all active messages occurring on the network. The Message Groups

column in the message browser indicates what server originated the

message. The messages originated by OVSACN are indicated by “Telco”,

“Telco Nokia”, and “Topology State Change.” Through the message

browser, you can review and manage these messages, and perform

problem resolution.

You can launch the topology GUI in several ways from the OVO GUI.

• From the Actions:Telco iNOCmenu, click Launch NT GUIor

Launch UX GUI.

• In the scoping area double-click on Applications:Telco iNOC->Launch

NT GUI or Launch UX GUI.

Once you have started the topology GUI, you can select a message in the

OVO GUI message browser and access more information about that

message through the topology GUI.

To access information about a message that is presented in the OVO

message browser in the topology GUI:

1. Select a message in the OVO GUI message browser.

2. Select one of the following menu items from the Actions:Telco iNOC

menu:

• Highlight in Map

• Show Problem

• Show Problem History

Introduction to HP OpenView Service Assurance for Communication

Relationship Between Messages and Problems

The OVO message browser and the topology GUI problems presenter

contain similar information for managing telecom equipment. Each

telecom message received by the OV Telecom Extensions for OV

Operations is correlated to a problem in the OV Topology Server and

each problem generated by the OV Topology Server creates a new

message in the OV Telecom Extensions for OV Operations. If the OV

Topology Server is configured, the choice of which window to use for

managing telecom equipment is a matter of network operator preference

and/or network operations center policy. The OVO message browser

contains a subset of all problem attributes, while the problems presenter

can display all of the problem attributes. The problems presenter can be

formatted extensively (hide/move columns, change column width) to suit

the operator’s preferences.

The interaction between the OVO message browser and the topology GUI

problems presenter is described below.

• OVSACN maintains the synchronization of the OVO message

browser and the topology GUI problems presenter. Changes to a

message’s severity, ownership, acknowledge state, or discharge state

reflect in the problems presenter. Similarly, changes to a problem’s

severity, ownership, acknowledge state, or discharge state reflect in

the message browser.

• When the topology server creates a problem because of a message

received from the telecom subagent, the problem severity is set to the

severity in the received message.

• When the topology server generates a new problem as a result of

correlating several received messages, it sends a message to the OVO

server so the message browser also includes a message about the

problem.

• When the topology server changes a problem’s severity, it sends a

message to the OVO server to update the severity of the

corresponding message in the message browser.
