Top Sources with Interfaces

Top Sources with Interfaces reveals interface metrics grouped by the flow source that exports them.

Identifying data transfer rate and capacity utilization from specific points on your network enables you to:

Identify packet choke points by checking where send or receive utilization is close to capacity.
Plan scaling and build out periods. Track high traffic routes over time.
Sanity check load balancing and track ToS-specific policies applied at routers.
Localize disruptive traffic to a specific router or interface.
Drill down into specific flow sources and configuration properties () of a particular network interface.
Be proactive.

Understand column data

The default view of each report contains a grid with the following columns:

Interface. Device hostname, IP address, or custom label grouped by Source with Ethernet port index. Index of 0 denotes the NULL interface.
Incoming Bytes. Number of bytes received. (Use Report Settings Sort by option to rank the list by packet or flow count, not bytes.)
Incoming Rate. Total average rate of inbound traffic.
Incoming Utilization. Fraction of total bandwidth capacity used. "N/A" denotes the measurement cannot be calculated because the bandwidth capability is unknown for the current interface.
Outgoing Bytes. Total bytes transmitted from the interface.
Outgoing Rate. Total average rate of outbound traffic.

To display Flow and Packet measurements, click a column heading () for column selection list (). You can also include:

Source Name. Device hostname, IP address, or custom label.
Interface Name. Textual name of the interface (ifName).
SNMP Index. Network interface SNMP table identifier (ifIndex).
In Speed. Inbound hardware speed.
Out Speed. Outbound hardware speed.
Tip: To show reports in full screen with most if not all possible columns, click on report options ( ) menu and choose Expand ().

Generate a report

Choose source. , Choose a networking device or single physical or virtual interface you want to see Top Sources with Interfaces measurements for. Choose traffic direction across an interface.

Choose time constraints. (,) Choose times for the Top Sources with Interfaces. (For recently observed measurements, select Last Polled from the Date Range drop down list.)

Filter and reduce by row and by column. Sort and remove columns, group rows based on specific column values, and remove unwanted information from the table.

Chart, adjust output, and visualize. Apply chart, geo mapping (World Map), and display options in Report Settings dialog (optional).

Export report data

Report data can be exported from WhatsUp Gold, reused, and distributed in multiple formats. Select Expand () from the Dashboard Options () menu. After the report has been expanded, select the Export Data icon to access the following options:

HTML. Generate and download a .htm file presenting your report data as it appears in the WhatsUp Gold user interface.
Excel. Generate and download a .xml spreadsheet containing your report data.
CSV. Generate and download a .csv file containing your report data.
Text. Generate and download a .txt file containing your report data.
Schedule Export. Set a recurring date and time, format, and email destination for report data export.
Important: 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.
