RE: [NV-L] How big can a seedfile be

the problem is that I don't know what I'd be looking for ,
in the objectdb. This project to see what there is to be seen, on the
network, not discover what we already know is there. I have, something
like 671,488 individual ip's in there, since I cut it and I have no idea if any
of those addresses should be alive or not. thanks
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.

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_______________________________________________ NV-L mailing
