We are a legacy installation of NetView, since the 4.x to 5.x days. We are
current at 7.1 heading on the current level this year.
Our implementation was architect way back last millennium. Our mission is
discrete:
Up/Down status polling on server class systems and network devices
(interface/node)
SNMP trap processing
Everything munges through with a single target path: T/EC, and then an
incident management system.
Way back when a decision was made to use /etc/hosts entries to make NetView
objects without domain names. It allowed us not to have to truncate the names
in T/EC.
However, with the increased use of clustering architectures, and assigning
multiple names and IP addresses to a physical server device, we're trying to
grok out how to properly distinguish between a cluster server (with an
associated IP address) and a cluster service (with another associated IP
address) end-to-end, from interface down/node down, all the way to incident
management.
I would greatly appreciate any thoughts on the subject, detailed on conceptual.
Should we be evolving our NetView configuration away from a local /etc/hosts
file?
Can NetView handle at discovery time associating different names (derivable
from DNS) as labels for different interfaces so we can treat a Cluster Service
(and IP) like a virtual node from detecting interface loss through to incident
management? We are extremely bullish on automation where possible.
