MetaConsole for Unicenter NSM: Getting Started for Canon Guide 4

Client

The client component includes three major sub-components:

• The console interface cooperates with the host console so the client functions in a

manner native to that console. For example, the console interface in the

MetaConsole client for Unicenter uses the Unicenter WorldView API and

ensures that the client performs all functions expected of WorldView

applications.

• The HTTP client layer communicates with the MetaConsole server using

Hypertext Transfer Protocol (chosen because it is a well-defined protocol that

works across firewalls). HTTP requests sent by the MetaConsole client contain

queries encoded in XML; the responses returned by the MetaConsole server are

also encoded in XML and contain style sheets with instructions for rendering the

XML data.

• The user interface component is generally common among MetaConsole clients

for different management consoles. This sharing provides the same “look and

feel” regardless of whether the user has Unicenter, another console, or a browser.

The user interface is rendered by the client using the style sheets provided by the

server.

The client might extend the common MetaConsole user interface in console-

specific ways to use all the capabilities of the management console. For

example, the navigation tree is usually adapted to reflect the native method used

by the console to display devices.

Server

The MetaConsole server includes two sub-components:

• The HTTP server controls communication with the MetaConsole client.

• The Service Provider Interface controls the communication with the various

service providers.

The MetaConsole server manages multiple service providers and takes care of routing

client requests to the correct service providers.

Service Providers

Each MetaConsole server has one or more service providers that can be loaded on that

server. Each service provider performs four main functions:

• Translates the HTTP server’s XML queries into the protocol understood by the

device and translates the device’s responses into XML documents

• Has a service mapping file that defines the translations from XML to the device-

specific protocol

• Discovers devices in the network

• Polls and listens for alarms from the devices that it is communicating with for the

purpose of asynchronous event notification
