- Here is (part of) the USERMAN.DOC, hope this helps.
- If anybody knows of a newer version of either beholder of gobbler,
- please let me know - thank you,

- The SNMP-able Ethernet Monitor
-
- By the DNPAP development group
- JPMvOorschot@et.tudelft.nl

-
- The Beholder
- The Beholder is a software-only product that implements a ethernet network
- monitor on standard PC hardware. The data collected can be obtained in
- three different ways, by looking at the PC screen, by requesting the data
- as SNMP variables, and by using TFTP to collect files with data. A standard
- ethernet Local Area Network (LAN) can contain several Beholder monitoring
- stations, each containing several network interfaces. Normal use will be to
- collect the data of all present Beholder stations to the network management
- node via SNMP. This data can then be processed to obtain problem reports,
- growth figures and performance measurements.
-
- The Beholder was developed by the Data Network Performance Analysis Group
- (DNPAP) of the Delft University of Technology. It is used as an important
- data collector in the "Intelligent Network Management (INEMA)" project.
- This project seeks to apply automated reasoning techniques to network
- managements.
-
- Main design goals of The Beholder were:
-
- . Minimum loss of packets
- . Continues operation
- . Appliance to Standards wherever possible.
- . Ease of Use
- The result of the developments is a PC based software package, capable of
- monitoring all traffic on one or more ethernet segments. The Beholder can
- be easily integrated in a SNMP based network management environment like
- Sun Net Manager.
-
- Hardware and Software
- The Beholder software runs on a standard 80<x>86 based Personal Computer,
- containing a network interface for which a "packet driver" network device
- driver is available. The Beholder was developed in ANSI C using the
- Microsoft C 6.0 compiler and two very small assembler files. For busy
- ethernet network, the PC should be at least a 80286 at 10 Mhz, but a 80386
- at 20 Mhz to be save.
-
- The WD 8003 family of ethernet cards is the preferred choice for ethernet
- network interface, but the 3COM line and the Novell NI1000/2000 will work fine.
-
- If the Beholder is used as monitoring station in combination with a network
- management station that collects the measurement data, no keyboard, mouse or
- display are needed as far as The Beholder is concerned. If The Beholder is
- used stand-alone, a standard PC display (colour is nice), keyboard and mouse
- can be used to view the results of the monitoring PC. The Beholder uses no
- graphics.
