Interface Traffic Direction Report displays...

across the selected external interface.
Flow Monitor: Top Senders with Most Failed Connections
This dashboard report displays the devices that initiated the highest number of unsuccessful
TCP connection attempts, or SYN packets, in the selected direction (Inbound, Outbound,
Inbound and Outbound, or Bounce) on the selected interface.
Essentially, the listed host has tried to establish a TCP connection to another device but has
not succeeded. Devices listed in this report may be conducting port scanning--a practice
used by hackers to find potential intrusion points on a network.
By default, devices are listed by hostname, however you can configure this report to list the
devices by IP address by selecting Display IP Address instead of Hostname on the report
configuration dialog.
Sender. Displays the host name of the top sender with the most failed connections.
Connection Attempts. Displays the number of failed connection attempts.
Percent of Top n. Displays the percentage ranking of the item with the top n items of
the category.
Tip: You can hover over a hostname to display popup information about the host name's IP
address. If you right-click the hostname, a filter is created that uses the host as the filter
criteria and the Interface Details dashboard reloads with this filter applied.
Note: WhatsUp Gold Flow Monitor can only find failed connections on sources that are not
sending sampled data.
