Leslie/Eddie,
Eyeballing is nice if you have that small network, for very large
environments this is unpractical.
In most large environments I have seen, users are working strictly with the
event browser and don't have time to go through the map to perform this
heuristic search.
Other products you didn't mention that do downstream event supression are
SMARTS IP Fault Manager, which now works with Tivoli/Netview 6000, and
Seagate Nervecenter 3.5.
Both of these products rely on accurate topology information from the
NetView database.
SMARTS works more quickly out of the box; Nervecenter is less expensive. If
you don't have a large staff dedicated to help build and refine rules,
SMARTS is a good choice. If you have the staff to dedicate to maintaining
and building custom models, Nervecenter has more flexibility.
If your network is large enough that event supression is an issue, then you
probably want to evaluate these products, along with the ones Leslie
mentioned.
Look at all the criteria that are important, not just functionality:
-Cost
-Functionality
-Ease of Maintenance
-Vendor Supportability
-Ease of Use
-Flexibility
Weight these criteria based on what is important to you.
Good luck,
Jerry

Ah, the holy grail of network management. No, it is not built in to the
product. However,
the tools to do it are there, with the ruleset editor. Since rulesets now
honor Collections,
this has become easier to administer and is doable for small to medium
sized networks
that are fairly static.
For larger networks, there are a number of add-on options on the market. I
have not used
them, but others here may be able to give you some feedback:
Usually when this question comes up, we hear from http://www.tavve.com.
Also, Tivoli has recently acquired and now offers Tivoli Manager for
Network
Connectivity, which sits between Netview and the T/EC and handles
correlation. More
info on that is at http://www.tivoli.com/o_products/html/netcon.html.
I like eye-ball correlation best. It's free and no work.
Cordially,

Subject: Down Stream Event Suppression
Hello,
I haven't been using the last couple versions of Netview. Has suppression
of events from downstream devices been addressed in the later versions? I
know there was an example in the Redbook for version 4 of Netview, but I
was
wondering if such functionality has been added to the base product.
Regards,
Eddie
