About the Interface Errors Last X hours/days (Single Device) report

This device-level dashboard report displays graphs that detail the percentage of interface errors for inbound and outbound data packets for all interfaces on a device during a selected time period. Adding this dashboard report to a dashboard allows you to monitor and troubleshoot interfaces experiencing packet error problems.

To display a single interface, use the Performance: Interface Errors (Last X hours/days - Specific Interface) 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.
   • 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.
   • Maximum number of graphs to draw. Enter the maximum number of interface utilization graphs you want to display.
   • 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.
