Start with the MRTG main page. I believe it was at the
end of the slide set I posted the other day in the first
of this thread. If it wasn't there, then the main
SNMP FAQ pages have it. (That was definitly at the end
of the slides.)
If there aren't any links off of that, try Google.
I didn't save my bookmark pages from the time in PHX,
but hunting specificly on MRTG should dredge stuff up.

The device has to first be configured where to send the traps,
which to send etc. After that, there are no handshakes associated
with traps. If a trap event happens, if the device still can send
a trap, it sends it while it still can.

Generally, 'a set' of MIBs will be associated with the Agent.
The MIBs come first, without them, there isn't any standard way
to interpret the information from the agent, or even to
query it to begin with.
The MIBs describe the data structures/variables the Agent
is designed to provide.

For those in RFC, IETF.
for those in Enterprise MIBs, the device/software
manufacturer.

From the below cited article:
*Warning*
sysctl is a very powerful tool. ...
Test all changes on a non-production system first.

Probably all currently available versions.
According to the article, all BSD 4.4 Lite based versions.

"FreeBSD's sysctl Interface" by Michael Lucas.)

I don't think my Warp 3 system has any support for it, but
I haven't really checked yet.

Again, see the references section of my pages.

The UCD package consists of some stand alone programs.
Rexx is a 'glue language', that should be able to
glue the UCD programs together to provide the desired
effect.

I'm currently ramping up for a new job.
While it does not directly involve OS/2, I apparently will be
using a DOS progam a lot, and it seems like running it under
OS/2 will be feasible, and in fact the best way to, so maybe
I can have a screen of this going on.
