thanks Leslie:
what is the eta of running this, on 84888 ips, assuming 10%
of the nodes are actually up? 24 hours? 12 hours? oh, and
assuming line speed (this servers are in the same building as the netview
servers, so we're not concerned with latency of the
network).
what am I checking again for - there is no "I am done with
this list, at least for first discovery" message in the trap log , is
there?
I have to present this data to a group of people and I
can't say definitively that the scan is done, it seems. or am I missing
something? will turning RFI off help?
thanks again
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.

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?
