Using the Web Performance Monitor

The Web Performance Monitor extends the functionality of the Microsoft Windows Performance Monitor to the Web. It is a data collecting and graphing utility designed specifically for the WhatsUp Gold Web interface that graphs and displays real-time information on user-specified SNMP and WMI performance counters. It can be used for a quick inspection of a specific network device.

The graphs can be saved to the database and displayed on workspace views using the Split Second Graph - Performance Monitor workspace report or on the Web Performance Monitor tool. Multiple SNMP and WMI counters can be displayed on a single graph, and the color and scale of each graphed item can be individually configured.

Graphs created with the Web Performance Monitor are saved on a per-user account basis, meaning, graphs are only accessible by the user account that created and saved them.

The Web Performance Monitor has two purposes:

• To provide a Web enabled WMI and SNMP performance counter poller and grapher. It supports WMI for Windows servers, and SNMP for network devices such as switches, routers, and UNIX devices.
• To build and edit graphs for use by the Performance Monitor workspace report. You can use this workspace report to display any saved graph.

To add a WMI performance counter to the Web Performance Monitor:

1. Open the Web Performance Monitor.
   • From the web interface, click GO. The GO menu appears.
   • If the WhatsUp section is not visible, click WhatsUp. The WhatsUp section of the GO menu appears.
