ELM Web Viewer

The Web Viewer The Web Viewer is an HTTP/XML-based interface to ELM Server Objects, Internet Explorer 6.0 and above is the only suppored web browser . The server side of the Web Viewer is installed using the setup package for ELM. The client side of the Web Viewer is any Javascript/XML-capable Web browser. Because the client side is simply a Web browser, most organizations will not have to deploy any additional software to client machines in order to utilize the Web Viewer. provides a read-only view of your ELM Server ELM Server is comprised of several engines that handle tasks such as creating and maintaining a database for data storage, archiving and reporting, managing Agents and Agent licensing, processing Event Filters, and executing Notification Methods. data. You may also enable and disable items, and view reports that have been saved and output in HTML format.

If IIS is installed on your ELM Server, during installation of the ELM Server you are presented with an option to automatically create an ELM virtual directory on the ELM Server. If your IIS server is running multiple Web Sites (also known as Virtual Web Servers), you can select which Web Site should contain the ELM virtual directory. The virtual directory should point to the WebSite directory on your ELM Server (by default, C:\Program Files \ ELM Enterprise Manager \ WebSite).

The Web Viewer provides access to the following items:

•Monitoring

•All Monitors

•All Notification Methods

•Event Views

•Performance Data

•ELM Publisher Reports

The Web Viewer is implemented using COM objects within ASP.NET Web Server Pages documents. It uses the Extensible Markup Language (XML) as the transport mechanism for the data, making it lightweight and fast, and XSL (XML Styles) to format the data's appearance.

The Web Viewer can be installed on Internet Information Server/Services 5.0, 5.1, 6.0, 7.0, and 7.5. Integration with IIS means that you can secure the Web Viewer from unauthorized use. In addition, you can control the name of the virtual directory, the port, and other properties. The Web Viewer server components must run on the ELM Server computer.

After installation on the server, the Web Viewer can be accessed by pointing a Web browser at the virtual directory (by default ELM). For example, to access the Web Viewer on the local machine, point a Web browser to http://localhost/elm.

Web Viewer Security

Secure the Web Viewer against unauthorized usage or access in three ways:

•Secure IIS - Microsoft has several security documents for Internet Information Services. These documents should be reviewed carefully, and steps should be taken to secure the IIS server.

•Secure Containers and Items in the ELM Console - You can use native Windows access control lists (ACLs) to secure containers or individual items. These settings are made through the ELM Console snap-in, and are respected by the ELM Web Viewer.

•DCOM Security - Windows Component Services can be used to restrict or grant access for remote Web Viewer users. To grant access, give the user Launch and Activation permissions to the TNT Software application registered with DCOM. See Web Viewer Security for more details.
