About the Interface Discards Last X hours/days (Specific Interface) report

This device-level dashboard report displays a line graph that details the percentage of interface utilization discards for inbound and outbound packet data for a specific device interface during a selected time period. Adding this dashboard report to a dashboard allows you to monitor and troubleshoot interfaces experiencing packet discard problems.

To display more than one interface, use the Interface Discards (last X hours/days - Single Device dashboard report.

To configure this dashboard report in WhatsUp Gold:

1. In the title bar of the dashboard report pane, click Menu > Configure. The Configure Report dialog appears.
2. Enter or select the appropriate information for the following boxes.
   • Report name. Enter a title for the dashboard report.
   • Device. Select a device by clicking the browse (...) button.
   • Interface to graph (available in some dialogs). For devices that have more than one interface, select an interface to graph.
   • Date range. Select a date range from the drop-down menu. The default is 4 hours.
   • Graph type. Select the type of graph you would like the report to display.
   • Trend type. Select the type of trend you would like the report to use.
   • Dimensions. Select the dimension in which you would like the graph to display.
     • Width. Enter a width for the report (in pixels).
     • Height. Enter a height for the report (in pixels).
   • Vertical Axis Scaling. Select either auto or fixed scale.

   Tip: WhatsUp Gold ships with Auto Scale selected for the Vertical Axis Scaling. Depending on your network characteristics, Auto Scale may cause graphs to have extreme peaks on the graph. After you configure a graph, you may want to watch your network performance for a period of time to determine the typical number of interface errors, then set the Vertical Axis Scaling to a fixed scale with a min and max scale that is tuned for your network. This will help you better identify the interface error values that are of real concern.

   • Min. Enter a number for the lowest point on the Y-axis.
   • Max. Enter a number for the highest point on the Y-axis.
   • Graph the maximum. Select this option to display a graph of the maximum value over the selected time period.
3. Click OK to save changes.
