Re: [NV-L] Finished scan?

Those are 'hints'. First it goes through
that whole list and makes hints with just those two fields. Eventually
(probably before it makes 84K hints) it will start making networks and
segments to support the addresses and masks, if it knows them, then it
will make interfaces to put on the networks, and then it will make the
nodes. So doing it that way, with a very long explicit list, can look like
it takes a very long time.   You might just give it overnight and
check again.  It sounds pretty normal.

Probably in the long run it will take
the same amount of time, but there are other ways to approach it. One would
be to make the range rules, as I am sure you have tried, and then run a
ping script that pings all of those addresses from the outside. That would
be a 'one at a time'  (one interface, network, and node) approach
that might give you more immediate feedback than the method you are using
now, which is more batch-oriented (make all the hints, then make all the
networks....etc). 

One down side of doing it with a long
explicit list is that Netview kind of hopes that all those entries are
SNMP. You can end up with a lot of bad subnet assignments if you don't
have some routers in there first, so real subnets are created. Then the
things that are non-snmp are likely to be assigned to good subnets.

Subject	[NV-L] Finished scan?

Dear learned folks:

I have a seedfile that is 84444 entries long.  I don't see any other "A node added" records in my trapd.log from restarting netmon.  It looks like the discovery only took about an hour. I tried to tease about the data with:

nvUtil e isNode=TRUE

But I have a lot of entries in the database that look like this:

bkain1@fcis249:~ $ ovobjprint -s fcas534.dearborn.ford.com
               OBJECTID                SELECTION NAME

OBJECT: 5480

        FIELD ID        FIELD NAME                      FIELD VALUE
       10              Selection Name                  "fcas534.dearborn.ford.com"
       11              IP Hostname                     "fcas534.dearborn.ford.com"

So isNode didn't pick it up.

Is discovery finished?  Why aren't the entries for most nodes being filled in?
