Interface Errors and Discards
Interface Errors and Discards report reveals interface error and discard data. A packet can have more than one error.
- . Device hostname, IP address, or custom label. This is the host where the interface is configured.
- . Text string associated with interface.
- . Packet error count on transmit.
- . Packet error count on receive.
- . Count of packets abandoned at transmit time.
- . Count of received packets discarded.

: Trend lines represent a moving average that can be compared with line and area graphs to reveal peak and sub peak intervals, collision periods, and indicate transmission problems.
: This report only returns Interface Errors and Discards metrics for devices that already have the appropriate WMI or SNMP credentials. For more information, see Using Credentials.
: To harvest data for this report, you must enable collection of Interface Utilization performance monitor data collection under Device Properties and ensure the interface data collection configuration option is selected

Export report data
Report data can be exported from WhatsUp Gold, reused, and distributed in multiple formats. Select (
) from the Dashboard Options (
) menu. After the report has been expanded, select the Export Data icon to access the following options:
- . Generate and download a .htm file presenting your report data as it appears in the WhatsUp Gold user interface.
- . Generate and download a .xml spreadsheet containing your report data.
- .Generate and download a .csv file containing your report data.
- Generate and download a .txt file containing your report data.
- . Set a recurring date and time, format, and email destination for report data export.
: Current report data file format options are only applicable to export schedules created using WhatsUp Gold version 2021 and later. Any report data export schedule created using an earlier version of WhatsUp Gold will still result in a .PDF output until that schedule is removed from, then recreated in the Scheduled Reports Library using the latest version of WhatsUp Gold.
