This window
(View
=> Statistics) displays vital network
statistics of your WLAN segment, such as packets per second rate,
bytes per second rate, Ethernet protocols, and IP protocols and
sub-protocols distribution graphs. You can copy any of the graphs
to the clipboard by double-clicking on the graph. Ethernet
protocols, IP protocols and sub-protocols "pie" graphs can be
rotated using the small buttons in the lower right corner for
better visibility of the slices.
The data
displayed on each page can be saved as a bitmap or comma-delimited
text file using the context menu or drag-and-drop. The
Report
page allows
you to have CommView automatically generate customizable reports in
HTML or comma-delimited text formats.
Network
statistics can be collected either by using all the data that
passes through your network adapter or by using the rules that are
currently set. If you want the statistics counters to process only
the data (packets) that match the current rule set and ignore all
other data, you should check the Apply
current rules box.
General
Displays
Packets per second and Bytes/Bits per second histograms, a
bandwidth utilization gauge (traffic per second divided by the
wireless adapter speed), as well as the overall packet and byte
counters. Double-clicking on the gauge brings up a dialog window
that allows you to manually configure the adapter speed to be used
in the bandwidth utilization calculations.
Protocols
Displays the
distribution of the Ethernet protocols, such as ARP, IP, SNAP, SPX,
etc. Use the Chart by drop-down list to select one of the two
available calculation methods: by number of packets or by number of
bytes. If your WLAN uses WEP or WPA encryption, you must configure
the WEP or WPA keys correctly to be able to decrypt network
traffic; otherwise, this chart will be empty.
IP Protocols
Displays the
distribution of the IP protocols. TCP, UDP, and ICMP. Use the Chart
by drop-down list to select one of the two available calculation
methods: by number of packets or by number of bytes. If your WLAN
uses WEP or WPA encryption, you must configure the WEP or WPA keys
correctly to be able to decrypt network traffic; otherwise, this
chart will be empty.
IP Sub-protocols
Displays the
distribution of the main IP application-level sub-protocols: HTTP,
FTP, POP3, SMTP, Telnet, NNTP, NetBIOS, HTTPS, and DNS. To add more
protocols, click on the Customize button. This dialog allows you to
define up to 8 custom protocols. You should enter a protocol name,
select the IP protocol type (TCP/UDP), and port number. Use the
Chart by drop-down list to select one of the two available
calculation methods: by number of packets or by number of bytes.
If your WLAN uses WEP or WPA encryption, you must configure
the WEP or WPA keys correctly to be able to decrypt network
traffic; otherwise, this chart will be empty.
Sizes
Displays the
packet size distribution chart.
Hosts by MAC
Lists active
WLAN hosts by MAC address and displays data transfer statistics.
You can assign aliases to MAC addresses. If you have too many
multicast packets on your network and the Hosts by MAC table is
overpopulated, you may want to group multicast addresses to one
line that will be named GroupedMulticast. You can enable this
function by checking the Group multicast addresses box. Please note
that only the packets that arrived after this option has been set
will be grouped accordingly, the previously received packets will
not be affected by this option.
Hosts by IP
Lists active
WLAN hosts by IP address and displays data transfer statistics.
Since IP packets captured by the program can be originated from an
unlimited number of IP addresses (both internal to your WLAN and
external), by default this tab does not display any statistics. To
have the statistics displayed, you should first set the range of IP
addresses to be monitored by clicking Add/Set Ranges. Normally,
these ranges should belong to your WLAN, and configuring the
program to monitor a certain range of IP addresses allows you to
have the usage statistics. You can enter any number of ranges, but
the total number of IP addresses being monitored cannot exceed
1,000. To delete a range, right-click on the list of ranges and
select the appropriate menu command. You can assign aliases to IP
addresses. Additionally, you can check the All box to have the
program list all IP addresses; however, this option is not
recommended for RAM and CPU utilization reasons.If your WLAN uses
WEP or WPA encryption, you must configure the WEP or WPA keys
correctly to be able to decrypt network traffic; otherwise, this
chart will be empty.
Matrix by MAC
This page
displays the graphical conversation matrix between hosts based on
their MAC addresses. The hosts represented by their MAC addresses
are placed on the circle, and the sessions between them are shown
as lines that connect the hosts. Moving the mouse over a host
highlights all connections that this host makes with other hosts.
You can change the number of the most active host pairs that are
displayed in the matrix by changing the value in the Most active
pairs field. To change the number of the latest address pairs
examined by the program, modify the value in the Latest pairs to
count field. If your network segment has many broadcast or
multicast packets that overpopulate the matrix, you can ignore such
packets by checking the Ignore broadcasts and Ignore multicasts
boxes.
Matrix by IP
This page
displays the graphical conversation matrix between hosts based on
their IP addresses. The hosts represented by their IP addresses are
placed on the circle, and the sessions between them are shown as
lines that connect the hosts. Moving the mouse over a host
highlights all connections that this host makes with other hosts.
You can change the number of the most active host pairs that are
displayed in the matrix by changing the value in the Most active
pairs field. To change the number of latest address pairs examined
by the program, modify the value in the Latest pairs to count
field. If your network segment has many broadcast or multicast
packets that overpopulate the matrix, you can ignore such packets
by checking the Ignore broadcasts and Ignore multicasts boxes. If
your WLAN uses WEP or WPA encryption, you must configure the WEP or
WPA keys correctly to be able to decrypt network traffic;
otherwise, this chart will be empty.
Report
This tab
allows you to have CommView automatically generate customizable
reports in HTML (including images of charts and graphs) or comma
-delimited text formats.
It is possible
to have the program generate statistics on pre-captured data in
addition to real-time statistics. To do that, load a capture file
in Log Viewer and
click File => Generate Statistic. You can optionally reset
previously collected statistics displayed in the Statistics window.
Please note that this function will not show packet distribution
along the timeline. It is limited to displaying totals, protocol
charts, and LAN host tables.
