Datacenter Network Management/ NetOps / Admin question

This is a broad question addressed to consumers of NMS (Network
Management Systems) dealing with large networks (organically growing
nodes) or just stable size datacenters. This is a sweeping term that
covers IT Network Managers, IT Admins, Network Ops, Cable Operators,
Hardware Integrators, Vendors..etc...anyone dealing with Network
Management (host side network monitoring or management)

1. What % of your network is manageable through SNMP (an SNMP based
manager/NMS) -- would you say for example X% is managed through SNMP
and the rest of the (100-X)% is managed through methods other than
SNMP (because there is no MIB support for certain aspects etc). What
is X in your experience?

2. If you use something like HP OenView etc. then are you able to
cover the entire (100-X)% that can be dealt through SNMP?

3. Could you please give me an example of how the other 50% looks
like? Are these mostly manual configuration scenarios or WMI/SysLog
based monitoring and maual actions? Server/Hardware recovery/power-
cycle secnarios?

4. Are there any MIBs for network security configurations -- these may
be vendor (for example Cisco proprietary MIBs for their firewalls)
specific, but are there standards yet for the general purpose security
configurations? If so what are these RFCs?

Any response is appreciated. Please respond with positive
identfication if possible. References to articles, RFCs, URLs are
welcome. Someone has done research in this area (or) want to research
in this area, and want to invoice by the hour for their work, please
respond here as such.
