If you have NetView for UNIX, they are
on the installation CD. You install them in the same manner as you
did NetView, either from the Tivoli Framework or with instalnv, (instalnv
-k BOOKS). They are installed into subdirectories of /usr/OV/books
as html and pdf files. Both are searchable.
On Windows the are automatically installed
as part of the standard installation. They are installed into subdirectories
of \usr\ov\books as html and pdf files
Or you can download copies from
http://publib.boulder.ibm.com/tividd/td/NetView7.1.html
if you can access that

I am interested in reading articles about discovery, polling
etc. Which books should I install to get this information ?
Many thanks in advance.

The answer to how netmon works is exceptionally complex, but I think
the answer you are looking for is "lists of objects with similar polling
characteristics gleaned from the topology database"
The ARP cache is used for discovery, that's all. netmon determines
what to check next by the xnmsnmpconf database and the timestamps in the
topology database ( managed by ovtopmd) of when he did it last. You
can see what's in that with "ovtopodump -rl", though I'd direct
that to a file as it will be voluminous.
To really get a handle on how netmon works, I suggest that you start with
man page (man netmon) and then get familiar with the "netmon -a<num>"
commands. They cause him to dump the various lists he is working
to the /usr/OV/log/netmon.trace file. And if you are really curious
about how netmon handles a particular scenario, then turn on the full trace
"netmon -M -1", do the thing, and then run off the trace "netmon
-M -0" and read the file. Of course, there are also the books
we ship, which have discussions on discovery and polling and so forth in
them. You did install the books, didn't you? They are a separate
installation from the actual code.
