no, we have not tried loadhosts since we're talking about a
seedfile that is 633333 lines
Does the same thing happen if you use LOADHOSTS?
I have seen a
similar problem if one of the seed entries does not exit. It hangs at that
point.

If
I'm not mistaken, netmon reads the entire seedfile during its startup process
before doing anything else. It adds "hints" (in the ObjectDB) for every
seed entry that isn't already discovered. So I'm "guessing" that after all the
hints have been created, there isn't further need for those entries to be kept
in the seedfile, regardless of whether or not the device has been discovered
yet.
netmon will then attempt to
discover those hints while also performing all of its other duties such as
status polling, daily config checks, and servicing other requests such as
demandpoll, but I don't think it needs to refer back to the seedfile after
that, and since the seed entries are in the ObjectDB as hints, you can
most likely even restart netmon and it still wouldn't need to see those
same list of entries in the seedfile.
Anyway have any comments on this ? Becki, look for hints in the
ObjectDB (using ovobjprint |grep <blah>) for your seed entries (that
have not yet been discovered) to check this theory .....

i had thought about having little seedfiles, in
fact, that is what we were initially doing but because there's no "okay, I'm
done" message in netview, I'm never certain when to swap out to the next
one.

big can a seedfile be
One thing you could try is to take the IPs of a small group of
devices that aren't being discovered and add them to a new seedfile. Then
temporarily configure netmon to use that seedfile and see what happens. May
want to copy all your entries that have polling/processing directives as well,
just for good measure.
I'm not really sure what is or isn't standard practise for the
majority of customers, but I'd say that a "best practise" could be to remove
entries from the "active" seedfile that have already been discovered (no need
to seed them anymore). You can always keep a master copy of a seedfile that
has every single IP you would like to store in a seedfile for some other later
use.
The only
entries you need to keep in an active seedfile are those with
"directives" such as HSRP (%) or SNMP Status polling ($) or the
locking of the SNMP Address (=), etc. All other entries can be removed once
discovered.

Ford had a PMR
opened in 2003 to ask that question and the answer was pretty big, as I
recall. However I think it is possible that the problem is that when you
specify every address, then at startup netmon is going to check on every
address whether it exists or not. I think I would enable tracing on netmon,
then watch netmon.trace when you do a netmon -y. It posts a message when it is
done loading that includes the word "sucessfully". Try putting a
misspelled node name at the end and see if the reload calls it out. If you
ping the address you are looking for (from the commandline) and grep it in
netmon.trace, you will see if netmon is getting around to trying to add it or
is trying but giving up for some other reason. It's just not how it was
intended to be used, so it is not optimized for it.
As for the link
business, I just tried it and it worked fine. Moved a seedfile to somewhere
else, and added a link where it was, and did a netmon -y. The resulting
message in netmon.trace says it was loaded successfully.

What is the limit, if
there is one, on the size of a seedfile? Right now, mine is
huge:
-rw-rw---- 1 bkain1 bkain1 16783342 May 23
19:07 seedfile (this is on suse linux 9)
And it seems like the addresses that were added at
the end are not getting discovered, yet I can snmp walk them. And can
the seedfile a link, as specified in netmon.lrf, or does that have to be the
actual file listed? Thanks_______________________________________________
