Well its not an issue of wether or not
netmon is picking it up in real time, because as I said earlier we’re
tailing the trapd.log and that’s how we find out a node went Down or Up.
What we’re looking to do is verification that the Down was a positive
down, not some sort of flapping. We know in NetView that netmon will eventually
pick it up and change the state of the object to Marginal or Up or whatever it
is, but we don’t want to insert anything into the database unless its
confirmed. SO if we see a Node Down, we verify it by opening up a tcp
connection to a known open port X times, if it is down, we insert data into
Oracle. Its not so much real-time, but just for verification. At the same time,
we have operators that monitor the NetView console and open tickets when they
receive Node Down events. We would like to prevent that from happening by
changing the status of the object if we know it was a false down up, because
our script would verify it immediately after the Node Down event came through
the trapd.log. I hope I am making sense..

Well, I think you have a number of
options. Lets take a step back and make sure I have an understanding of
what the problem statement is:
You are using Node Up/Down events to
gather SLA stats (stored in an Oracle
DB). You have found that Netview is not issueing the Node Up/Down in
"real-time", i.e some time after the device actually changed
state. You are looking for means proactively change a state of an
object w/in Netview to facilitate closer "real-time" gathering
of SLA stats.
Does that sound about right?

Well we have netmon polling it, but we are
relying on information from the trapd.log to use for SLA
data. Like if we get a Node Down event or Node Up event, we put that into an
Oracle database. We are trying to verify that the Node is really down, in a lot
of cases in our network a Node will go down, and then an operator will do a
demand poll or ping it, and then it will start responding again. So we have a
script that tails the trapd.log file looking for Node Downs and if it receives
one, it does a test trying to open a tcp connection a few times to verify that
its really down, if it is, it gets inserted into the database. We also want to
change the status of that object back to Node Up before netmon gets a chance to
do it. Now of course there are other ways to do this verification by having a
ruleset that has an inline function that does this but we had some problems
with that..
So what do you think I should do? Use the
API and OVwSetStatusOnObject to
change the status, or is there an easier way?
Thanks in advance!

You can use the API, but if you have
netmon polling that IP device on interval, it will notice the incorrect status
and change it back. Start at "man OVwSetStatusOnObject", this
will give you a start. If you have any specific questions, feel free to
ask. Some statuses are "Reserved" and it wont allow you to
change it via the API (eg Acknowledged), but there are programmatic ways around
that.

We are trying to find a way to modify an object in NetView.
If we know the node name, and want to change its status from say down, to up,
because of an additional verification that proved it was up, how would we go
about doing it? Are there any utilities or where should I look in the API?
Thanks,
Mike
