Here's my take:
Mike - I'm not sure having over 40 programs to accomplish network and system
management is an impressive thing. In fact, the current issues with the
extended topology (layer 2 from Riversoft) is:
- only scales to 500 nodes
- GUI is NOT tied into OV NNM, so now we have 2 GUI's to see the network
issue
- it took over 1 1/2 years for them to bring a limited functionality to the
market
- although a GUI is nice to view, but in a larger environment, GUI's tend
not to scale. In fact, most larger environments don't even use Cisco WAN
manager due to all the 'connections' on the screen, you can't see anything!
Imagine when OV ET supports more than 500 nodes in the next 2 years.
NetView has to offer:
- advanced GUI, Availability on the screen (no extra product to monitor,
install or maintain, all in one)
- headless web options, meaning I don't need to have OV running in order to
see product via the web
- as well, if I want to view it through the firewall, I can with 1 port, not
a ton of ports being opened
- from my understanding, the switch analyzer supports the current NV without
any additional configuration (haven't tested, but have requested it. Anyone
else found this out? Also, my colleague told me that it does correlation
without rule writing, how does this work any tivoli person know about this?)
NV does do the layer 2 diagnostics via the gui
- Smartsets. Need I say more.
- RFI does more than OV ECS out of the box. No configurations. (Tivoli
persons, curious how this works with Layer 2 Analyzer?)
Pricing used to be a big difference, however, it is now a level playing
field with Tivoli's announcements earlier this year. Yes, we do a lot of
install's of OV NNM, but we don't make any money with HP unless we install
agents. Customer's are not wanting the maintenance of agents anymore.
Don't know if Tivoli has a better approach, any info on this?

I agree that 90% is your processes and organization and 10% is your =
tools.
And that you need to look at functional areas. NetView and NNM =
basically
only does fault management.
And you are right that in the past a number of network management
applications integrated with NNM. A few still does and actually =
requires NNM
like Cisco Wan Manager (StrataView).
NNM has been doing level-2 discovery since 97 based on the bridge MIB =
(just
like Switch Analyzer). This didn't work well (problem with the support =
of
the bridge MIB from some vendors) and in addition it now uses NMOS =
combined
with the build in event correlation (since version 6) called ECS (Event
Correlation Services). This is a technology initially developed for the
OpenView telecom products.
The NNM web GUI also integrates other applications just like the native =
GUI
(via registration files). With NNM 6.31 a J2EE application server is =
build
in as well.
NNM doesn't run on Linux (only HP-UX, Solaris, NT and Win2k), but =
OpenView
in general do have agents.

NNM is the network management (SNMP) platform of the OpenView family like
NetView is for Tivoli. But OpenView is more than 40 other products covering
e.g. performance management (OpenView Performance for systems and OV
Performance Insight for Networks), system and application fault management
(OV Operations), Internet management (OV Internet Services), change,
configuration, SLA and helpdesk management (OV Service Desk) just to mention
a few. OpenView is not a product. It's a marketing brand.
From what I've seen of Switch Analyzer it's less than what NNM could do in
version 5 back in 97. As far as I understand it's not even graphical.
NNM ET combines the level-2 and VLAN views you see in e.g. CiscoWorks Campus
Manager with level-2 root cause detection.
I don't mean to advertise for OpenView in this forum (the OpenView Forum
mailing list is the place to ask if you want more information or simply look
at www.openview.hp.com), but I will answer technical questions based on my
experiences with OpenView as well as NetView in my work as a consultant.
Michael.

I suppose you mean that you want to compare NetView with OpenView Network
Node Manager (NNM). They pretty much do the same job (and was original
based
on the same code). They have moved in different direction when it comes to
new functionality like event correlation, distributed management and web
GUI's.
Can you elaborate on these differences?
The only place I really see a difference is on the level two
discovery and graphical layout. With NNM Extended Topology you'll
get functionality you'll otherwise only find in vendor specific
tools like CiscoWorks.
I'm curious how it compares now that Tivoli has released the IBM
Tivoli Switch Analyzer product.
