LANScan Network Summary
LANScan starts monitoring network activity immediately on startup. While it
is running, it constantly tracks network activit and compiles statistics on
usage. When LANScan starts, it automatically displays a Network Summary view,
highlighting key data about the network. An example of the Network Summary is
The view uses bar graphs and an Explorer tree to report network activity. The
tree can be expanded and collapsed to show data. In the tree are the bandwidth,
top hosts, top protocols and events.
Bandwidth shows the percentage of bandwidth used on the network over the
last sample period(10 seconds, by default), 5 minutes, 1 hour and 8 hours.
Typically, the higher the percentage, the slower the network will be able to
respond to users.
Top Hosts shows the top 5 network devices, according to the amount of
traffic generated. Use this feature to quickly identify possible causes of
Top Protocols shows the top 5 protocols in use on the network. This helps
identify the type of applications generating network traffic.
Events are LANScan objects which can report unexpected network activity, like
excessive bandwidth usage. The summary shows the number that are configured, and
how many of those are active, meaning the condition has been met (such as
'Bandwidth usage has exceeded 25% for the past 15 minutes").
