To get a first impression of the possibilities of Net-Control,
you should start first of all the data sampling process.

Net-Control has now begun to sample data in the background.
^T

^T:10,10
^A:74,21
R:11
The measured data is divided into time intervals. Momentarily
Net-Control works with a interval length of 30 seconds.
.
If Net-Controls data sampling process runs in the background
you see the remaining time of the actual intervall in
a small window.

^T:10,10

Let us switch now to the menu of

To finish a measuring interval, the data sampling process
of Net-Control runs still for about 10 seconds....
^T

^;  *** Stop the data sampling process ***
^N

^T:15,10
Now a measuring interval is completed, and
Net-Control shows you the corresponding data.

In this menu you see the actual values of the
network parameters.
For a first estimation the value of the
.
                ⌠Netload⌡
.
is of great interest.
D:30
^T

^T:15,10
^A:48,7
You can recognize immediately, whether an increased
.
                 ⌠errorrate⌡
.
was observed in the last observation interval.
D:30
^T

^T:15,10
As next we want to see we, which machines
at the network are already known to the program.
Enter ⌠B⌡ to see the list of known addresses...
D:30
K:B
^T
B

^T:10,10
^A:28,7
The known machines are sorted for their ethernet
hardwareaddresses. Each machine has a symbolic name.
For example: the hardwareaddress ⌠000000000015⌡
is known under the name ⌠odysseus15⌡.
.
(The assignment of the station names to addresses
is done in another menu of Net-Control.  )
D:30
^T

^T:18,10
^A:68,7
The total number of sent and received frames today
is shown for each address.
D:30
^T

^;Reference group
^T:18,10
^A:39,7
Net-Control can divide all known addresses in up to
40 groups for three different group definitions.
Here are three possibilities for the group definitions:
 I   - for segments in your network,
 II  - for the protocols used,
 III - for the different machine types.
.
⌠group 0⌡ means: not defined, unknown group.
D:30
^T

^T:18,10
^A:43,7
In this example the assignments in group 2 are:
.
   1:This station uses the IP protocol.
   2:Dec-Net
   3:Apple-Talk
etc.
.
As we will see later, with help of this group assignments
special evaluations can be done.
D:30
^T

^T:18,10
^A:42,8
The command ⌠C⌡ shows an evaluation for the known stations,
which indicates the date of the first and last appearance
of this station at the network.
D:30
K:C
^T
C

^T:18,10
^A:68,8
If the station was seen at the current date (today) on the
network, the time of the first and last appearance are
shown additionally.
D:30
^T

^T:8,10
It is also interesting, whether and which stations were
observed newly at the network. A list of these stations
is prepared for every day.
This list is shown by the command ⌠N⌡.
D:30
K:N
^T
N

^T:8,10
^A:44,8
The number of the transferred and received frames as well as the
time of the first and last appearance are shown for all new
stations. These stations are called "unknown addresses".
D:30
^T

^T:18,10
Of course, stations, which appear regularly, should be
taken over to the list of the known machines.
D:30
^T

^;*****************
^:HITLISTS
^;*****************

^T:18,10
Interesting and very helpful information is
offerered by the ⌠hitlists⌡ calculated by Net-Control.
D:30
K:H
^T
H

^T:10,15
There are 13 different types of hitlists.
.
The first of these hitlists shows the most active stations
of the last observation interval.
D:30
^T

^T:5,15
In the case of network problems these hitlists can give a
first reference to the station(s) which cause the problem.
.
In this list of the most active stations you should find first of
all the servers and routers in the network.
D:30
^T

3
^T:5,15
This is the hitlist of the most active connections. You can see,
which stations have communicated very intense in the observation
period.
.
You should pay attention, wether the amount of the sent and received
blocks is balanced. A disproportion can point to a disturbance in the
connection.
D:30
^T

4
^T:5,13
This disproportion is especially clear, if all blocks of a connection
are sent only by one station. This is called a "one-sided connection".
.
This is a "network pollution", if the receiving address is no
multicast- or broadcast-address.
D:30
^T

2
^T:5,15
This is the hitlist of the broadcast activity.
A clearly increased amount of broadcasts can be caused by
a problem at the causing machine.
D:30
^T

8
^T:5,15
Let us come now to the hitlists for the group classifications.
.
We remember, that the group classification II referred to the used
protocol. The hitlist shows thus, which protocols are involded in
the network traffic.
D:30
^T

7
^T:5,13
As last example of a hitlist we choose the hitlist of the
group classification I. Because this group classification was
defined according to the locations of the individual machines,
the traffic streams in the network can be recognized here.
.
This information is particularly helpful to restructure the network.
E.g. if you plan to integrate a bridge into your network.
