Well, I have not seen TFNC, only read about it. This function is right on
the
server, rather than on a separate box, and the resulting events are seen
right at the main events display rather than at the T/EC. It is also
different in
that it does not have to discover and load the relationships of the
topology.
Instead, it relies on the results of regular pinging.If it cannot ping any
router
interface on a subnet, it discards failing pings (or does not ping, I'm not
sure)
for other nodes on that subnet and marks it unreachable. It distingishes
between a router that is down, and a router that is unreachable because
some other router is down between it and the server. You don't get any
events about things that are simply unreachable.
If you have lots of nodes on the subnets, you will greatly reduce the
events
generated. If your discovery only includes the routers, you have already
reduced the events, and the percentage will be less, but the result is the
same: you don't get down events for remote routers if the cause is a
down interface on a local router. Some new algorithms are involved, and
polling sequences are changed on the fly to chase down related outages.

So does this root cause analysis provide the same functionality as TFNC?

At the time V6 was shipped, the final decision about how to charge for it
had not been made. So it was shipped with this feature locked, to be
enabled later by a key. Later, the decision was made to include it without
charge, and the 6.0.1 update will unlock it. You can also get a script from
support to unlock it now. I have put it on at my current customer, and it
is
working very nicely. We will need to think through the new events involved,
and which ones you want to handle in your rulesets, but it looks good.

Subject: [NV-L] Root cause analysis in Version 6
Hi,
Some post in this mailing list seems to say that the root cause analysis
feature is built in in Version 6.
>From what I remembered reading from the Release Notes, Version 6 comes only
with a new status color (white) that means that the path to the device is
through
a box which is down. To really have the feature to calculate and set
this white color, you need to buy an additional product from Tivoli.
I hope I did misunderstand this. Could somebody explain it to me?
Many thanks in advance,
Thierry
