Client
The client includes three primary sub-components:
1 The Console Interface cooperates with the host console so the client functions in a man-
ner native to that of the console. For example, the console interface in the MetaConsole
client for OpenView NNM uses the OpenView API thus ensuring that the client performs
all functions expected of OpenView applications. More specifically, MetaConsole inte-
grates with the OpenView Alarm Browser. The client makes an entry in its own log when
monitored events occur, but it also provides OpenView Alarm Browser with the information
needed for a standard OpenView error message. In MetaConsole J, the console interface
is between a browser and HTML pages and Java applets.
2 The Hyper Text Transfer Protocol (HTTP) Client Layer communicates with the Meta-
Console Server using HTTP. HTTP request sent by the MetaConsole client contain que-
ries 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.
3 The User Interface is generally common among MetaConsole clients for different man-
agement consoles. This sharing provides the same look and feel regardless of whether the
user has OpenView, NetView, MMC, Unicenter or a browser. The User Interface is ren-
dered 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:
1 The HTTP Server: Controls communication with the MetaConsole client.
2 The Service Provider Interface: Controls 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 should have a Konica Minolta service provider (referred to as Page-
Scope EMS Plug-Ins) that can be loaded onto that server. EMS performs four main functions:
1 Translates the HTTP server’s XML queries into the protocol understood by the device and
translates the device’s responses into XML documents.
2 Has a service mapping file that defines the translations from XML to the device-specific protocol.
3 Discovers devices in the network.
4 Polls and listens for alarms from the devices that it is communicating with for the purpose
of asynchronous event notification.
