I am searching for a utility akin to ``etherfind'' that will allow me to ``watch'' traffic on the domain-ring. It would be especially nice for analyzing why our 27-node ring seems to perform so poorly. Does anyone have such a tool they have written, or know of one available from Apollo Computer Corp.? BTW: What is the purpose of /systest/ssr_util/jam_net??? It seems to push packets out onto the ring when invoked. Thanks to anyone who is able to help with either of these questions. eric ;;;;;;;;;;;;;;;;;;;;;;;; Eric Ost Computer Science Dept. Indiana University emo@iuvax.cs.indiana.edu ;;;;;;;;;;;;;;;;;;;;;;;;

I use the RINGLOG and NETLOG programs in /systest/ssr_util to watch whats happenin on the network. Its nowhere near as nice as the traffic program on the Sun systems. Try it out - it produces more information than any of the APOLLO standard commands. Richard A. Bishopp Sys Admin p.s. Views here are my own - not Philips or anyone else

There are 2 different tools, supplied by Apollo, for monitoring network traffic.
The tool "netmain", documented in the "sys_admin"* manual, can be used to
monitor lots of events around the network. This includes network traffic,
CPU time, network hardware problems, memory problems, disk problems, etc.
There is a server "/sys/net/netmain_srvr" that is run as a background
process that gathers statistics and creates log files. There is a
user-interface program "/com/netmain" that is used to read and format the
log files. This tool has a bewildering array of options and can create large
log files if left unattended for long. The manual has lots of examples, you
may just have to try some out to get a feel for what it can do. It is a good
tool for network trouble shooting, one you learn it.
* "Administering Your DOMAIN system" (sr9)
"Managing {Aegis | BSD | Sys5} System Software" (sr10)
The tools "netlog" & "ringlog", which are not documented in any manual, can be
used to monitor network traffic at the packet type level. Netmain will give
packet counts and some general indication of netork paging levels, ringlog
and netlog can analize the types of packets on the network and their sources.
They can be used to fine-tune a network by finding out what types of files
are accessed most often on a server, which nodes do the most paging, etc.
Netlog & ringlog can be found in the directory "/systest/ssr_util" along
with various help files.
The tool "jamnet" is used to set the DOMAIN internet network number on one
or more nodes on a network. This is comparable to using "netsvc" to set the
network ID on each of the desired nodes. See the help file for netsvc and
the manual "Planning Domain Networks and Internets" for more information.
Warning: improper use of this tool can disrupt network operation.

The directory "/systest" contains various systems level diagnostics & debugging tools. This directory contains several megabytes of stuff and its installation is optional. If you can't find "/systest" on your disk, check with your system administrator as to where a copy may be found. You may have to go to the distribution tape set, if it was never loaded. In my posting <8901310201.AA00952@icaen.uiowa.edu>, I refered to the wrong manual for information on the "jam_net" tool. The useage of that tool is mentioned in the manual "Managing Domain/OS and Domain Routing in an Internet". Dave Funk
