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.
