I apologise for the late summary.

Thanks for all the responses to my request for SunOS monitoring tools.
I received several replies.

Original question:

> Does anyone know of any tools to monitor SunOS 4.X based machines? I
> am looking for something similar to the sar utility of the System V world.
> How do others monitor machine performance? I currently use the *stat commands
> to view the machine at selected times. Anyone written any scripts to
> manipulate the output of the *stat into some useful reports?


1) Several people mentioned using top, vmpage, nfswatch, mon, ethertop.
   All are freely available from ftp sites. Check archie for your
   nearest archive.

   I had a look at top3 and nfswatch. Both proved usefull for getting
   system performance data. However what I ended up doing is writing my
   own C program to get the data from the kernel and writing it to a
   data file. This meant I could produce graphs and reports easier.
   I plan to use GNUplot to produce graphs I need.

2) John Cieply suggested NETUSE (readme included below). Looks interesting
   I will have a look at this as well. I think this would be usefull at
   sites with a large number of hosts or a hetrogenous site.
3) SunNet manager software from Sun. Is an SNMP network monitor program
   that can be used to monitor Sun machines.
4) Dennis Bare (and others) listed the following commercial packages

                NETUSE - A Network Host Usage Monitoring System

                        Lee Liming and Michael L. Neil
                      Computer Aided Engineering Network

NETUSE is a low-budget, high-output network service used for keeping track of
dynamic information about hosts on a TCP/IP network. It is not limited to
physical networks; i.e., it's monitoring crosses routers. It monitors and
updates load averages, number of login sessions, display use, free disk space
in /tmp, host names, and vendor and model types for a (potentially large)
number of hosts. All of these items are determined dynamically by the system.
One never needs to tell NETUSE anything (other than to run).

Rather than being based on broadcasts, which are limited to physical networks
and which require processing time from all hosts on the network, NETUSE takes
a client-server approach. Periodic reports are sent directly to a server via
UDP, and the server may subsequently be queried for near-instantaneous

This service was originally developed for assistance with large-scale,
course-grained distributed processing (running jobs on lots and lots of
hosts!). It's strong points are low bandwidth requirements, speed of queries,
self-maintenance, and versatility.

NETUSE has been in wide use at CAEN for several years now, and we've been
adding features and making it more robust through most of that time. We now
feel that it's "good enough" (in terms of robustness and usefulness) to be
distributed more broadly.

The REAL documentation is in the ./doc directory, in several formats
(including plain old ASCII).
