The framed presentation page of this demo consists of three sections. The upper top section contains a Java applet displaying a scrolling text message. The lower left section displays the control options available to operate a copy of CSU application that is executed remotely. And the lower right portion displays the output of the CSU operations.
The control options on the lower left section contains several radio buttons, drop down menus and a "Submit" button. The radio button allows you to select to force a new "Sample" to be taken or to generate a new "Report" based on existing sessions. You can select a baseline session and optionally a compare session. The level of detail output is controlled by "Detail Filter Level". The options are "Expert", "Advanced", "Summary", "Checkpoint" and "Differences". Once the "Submit" button is pressed, the request is sent to the remote CSU and the results are sent back in HTML form and displayed in the lower right section. "(+)" indicates a new value that differs from the previous session. "(-)" indicates the previous value in the older session.
The remote CSU is either a Windows NT Service or a Netware NLM that runs on a NetWare web server machine. Therefore the results you see are the actual machine hardware and software information. We have implemented RCGI (Remote Common Gateway Interface) capability in this version of CSU. The primary difference between CGI and RCGI is that CGI code spawns off a process per user request while RCGI code resides in memory and communicates with the HTTP service via TCP/IP. The RCGI approach reduces resource burden on the server and enhances performance.
