Help: hitlists 22.03.93
There are 13 different types of hitlists, which are held
for the last time intervals. Each hitlist presents a small
(maximum 1.2 kB) text file. The number of the hitlist
is captured in the file extension ≤nnn≥ (with ≤nnn≥ by 000
to 014 if you have at maximum 15 versions). The hitlists are
written "in cycle", so that the extension 014 does not have
to represent always the newest hitlist.
≤DOS path hitlists:≥
The DOS-path, where these lists are stored, can be defined
in this menu point. Favorable is here (because of the faster
access) a RAM-disk. At the default value of 15 hitlists per
version is a size of 230kB and 195 file entries sufficient.
The content from a RAM-disk are losts after power down of the
system. Details for the arranging a RAM-disk can be taken
from your DOS-manual.
≤Number of hitlists:≥
The maximum number of hitlists, which may exist of each version,
can be editted her. If this amount is reached the oldest hitlist
is overwritten. Net-Control alleges an amount of respectively 15
hitlists; at increasing this value it is to be considered,
that the above indicated directory can hold sufficient entries.
≤The individual hitlists:≥
≤Most active addresses:≥
In the list (file name: EAK-ADR.nnn) the most active addresses
are stored. That are those hardwareaddresses, which have sent
the most packets in the corresponding time interval. In addition
to the hardwareaddress and the symbolic name (if known) the
absolute as well as the proportional amount of packets is shown .
≤Most active broadcast senders:≥
Broadcasts on a network can be disturbing, if they appear in
masses, since Broadcasts are received by all stations and must
be processed (even if the result of the processing leads to
throwing away the broadcast). Therefore it is important, to
determine massive broadcast transmitters. The list of the most
active broadcast senders is stored in the file EAK-BRO.nnn.
≤Most active manufacturer groups:≥
In the list of the most active manufacturers groups (filename:
EAK-MAN.nnn) the individual manufacturers of the ethernet
boards are identified using the first three byte of the ethernet
addresses. Those manufacturers, which have sent in the corres-
ponding time interval the most blocks on the network are stored
in this list. There is shown the absolute amount of the counted
packets as well as the percentage at all packets. Multicast-
addresses are not considered here.
≤Most active connections:≥
While in the list of the most active stations only one address
is important, in the list of the most active connections
(filename: EAK-CON.nnn) all connections between two addresses
are considered. The amounts of packets in both directions are
added to measure the activity of a connection.
≤Most active one-sided connections:≥
In this list only the one-sided connections are counted.
(Filename: EAK-1CN.nnn).
One-sided connections are connections with flow of packets
onlöy in one direction (no answer packets during the observation
interval). If there are many packets sent in such connections, you
should examine this.
≤Most active time intervals:≥
In this list (file name: EAK-INT.nnn) the time intervals with
the highest netload of the actual day are presented. In addition
to netload and time, the amount of the packets, of broadcasts and
multicasts, of the involved stations, just as the number of
one-sided and two-sided connections is stored. In contrast to the
other hitlists here exists one list for each day.
≤Most active connections of the defined groups:≥
The group hitlists (file name EAK-GRi.nnn with i of 1 to 3)
represent for each group assignment the most active connections
between the individual groups.
For example: If the group definition II has been made for the
different buildings, the list of the most active connections of
the groups definition II shows, how many blocks were exchanged
between the various buildings. This information is versy usefull
for a newdesign of your network.
≤Most active new addresses:≥
In the list (file name: EAN-ADR.nnn) the most active addresses,
which are nor in the list of the known adresses, are stored.
≤Most active new broadcast senders:≥
The list of the most active broadcast senders, which are not
"known" by now, is stored in the file EAN-BRO.nnn.
≤Most active connections with new addresses:≥
In this list are onloy stored those connections bewteen two
ethernet addresses, with at least one address beeing unknown.
This helps you to identify new addresses by knowing to whom
they "talk".
≤Most active one-sided connections with new addresses:≥
In this list only the one-sided connections are counted.
(Filename: EAN-1CN.nnn). As in the list mentioned above
only connections with at least one new address are inserted
in this list.
