NBAR Applications - Interface Totals
NBAR Applications - Interface Totals report reveals the top n NBAR-classified traffic categories observed at the network interface for the selected interval.
- . Application category detected by the Cisco NBAR identification engine.
- . Total number of bytes.
- . Average number of application bits transferred between two endpoints (browser and webserver, for example).
- . Percentage of overall traffic.
To display Flow and Packet measurements, click a column heading (
) for column selection list (
). You can also include:
- . Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.

Choose times for the NBAR Applications - Interface Totals. (Subject to NTA collection interval and retention policies.)
Choose time constraints for your NTA data view
Date Range . Choose or define an overall window of time network activity data.
: Detail rendered in graphs depends on the time window you choose (Date Range) along with how long your system retains raw, hourly, and daily time-series data (NTA data collection and Data Retention settings). NTA graphs network activity as time-series averaged over daily intervals, hourly intervals, or over shorter periods (raw). Raw data interval is defined by the Data Collection interval value in NTA settings.
: If you choose a time window outside of your NTA default data retention limits (47 hours for Raw and 19 days for Hourly, for example) your graph will default to an interval detail of Daily.
Detail Revealed with Default Retention Settings
Over time, the NTA collector cleans up older data. Eventually, collected data is combined into daily totals at the rates shown in the following table. If your site's mission and database capacity allow for more detailed data be retained for longer periods, increase the default retention settings for in the NTA Settings dialog ( menu ).

Example
|
0 – 47 hours
|
Raw
- Data interval = every two minutes.
- Default data retention = two days up to now. In other words, 47 hours plus the current fraction of the ongoing hour (unless extended in NTA Settings - Interface Data).
|
Class Based Quality of Service past 12 hours (raw detail dropped packets)
|
past 48 hours within the past 19 days
|
Hourly
- Data interval = every hour.
- Default data retention = 19 days plus the current fraction of a day (unless extended in NTA Settings - Interface Data).
|
Class Based Quality of Service last two days (hourly dropped packets)
|
20 days or more
|
Daily
Data interval = every 24 hours.
Daily is also the Archive data interval.

) 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.
