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.
