Top Sender Countries
Top Sender Countries report reveals geographic locations of devices sending the most traffic for the selected interval. Geographic information can be useful when tracking the origins of network traffic. For example, if your company has a website, you can detect the locations of the persons and businesses that are visiting your website by viewing the dashboard report.
- . Top sender country.
- . Number of bytes transmitted. Use Report Settings
to sort by packet or flow count, or bytes. - . Average bit rate, in bits per second (bps).
- . Percentage of the total traffic for the specific item in the report category for the selected date range.
To display Flow and Packet measurements, click a column heading (
) for column selection list (
). You can also include:
- . Two letter country code.
More...
- . The total number of packets sent/received for the current city and the selected date range.
- . The average packet rate for the current city, in packets per second (pps), for the selected date range.
- . Percentage of sent/received packets for the current city.
- . The average flow rate generated for the current city, in multiples of flows per second (fps) for the selected date range.
- . Percentage of received flows for the current city.
- . 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 Top Sender Countries. (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 in NTA settings.
: If you choose a time window outside of your NTA default data retention limits (8 hours for Raw and 10 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 in the NTA Settings dialog ( menu ).
