Add/Edit SNMP Performance Counter

Use this dialog to add (or edit an existing counter) an SNMP performance counter to the WhatsUp Gold Web Performance Monitor. This counter will be displayed on the graph within the Web Performance Monitor.

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

1. In the Add SNMP Performance Counter dialog, enter the appropriate information into the following fields:
   • Computer Name. The name of the device connected to the Web Performance Monitor. This field is automatically populated for you.
   • Descriptive Name. Enter a name for the performance counter. This name is displayed in the legend below the Web Performance Monitor's graph.

   Tip: It is a good idea to leave the name field blank. Typically, when you select a counter (below) a default display name for the counter is supplied and will display itself in the name field.

   Tip: If you are graphing items from more than one device, it is helpful to include the name of the device with the counter name, for example, "ServerXYZ: Processor Utilization."

   • OID/Instance. Select a SNMP counter by clicking the browse (...) button. After you select a counter, the OID and Instance fields will populate with the type and instance of the counter you select.
   • Color. Select a color for the counter by clicking the browse (...) button. This color is used in the Web Performance Monitor graph for this specific counter. If you are graphing multiple counters, this color differentiates it from the other counters.
   • Scale. Use this to change the magnitude of the graphed values. For example, a value of 100 with a scale of 0.1 will display as 10. A value of 2912 on a scale of 0.01 will display as 29.12. The raw polled value is multiplied by the scale to determine the actual graphed value. The default scale is 1.0.

   Tip: Scaling is useful when displaying multiple values on the same graph that have significantly different magnitudes.
