HP Openview Network Node Manager
first implemented HP Openview at the Internet Service
Provider Colt Telecom in
Amsterdam, Holland in October 2000. I evaluated the product and
installed a test system in connection with a feasibility
study. I prepared both the technical proposal and budget for
I was subsequently the project manager
for the implementation of HP Openview and CiscoView on two Sun 220R platforms
running Solaris 2.7. These two systems ran as a fully
redundant system using Network Node Managers automatic
failover mechanisms. I also implemented the NNM companion product Customer
Views which displays customer equipment in their own maps.
The customer details were entered into a simple SQL database running on
a Windows NT server interfaced with a third part ODBC link
to the HP Openview customer views database. The
database was maintained using a web browser written in PHP4.
I also installed CiscoWorks and its Network Node
manager interface. This NNM implementation also interfaced

version of Network Node Manger. I carried out some map
maintenance but my experience was mainly as a user
subsequently joined the Operations department of a
leading Pharmaceutical group who provide Networking and
Computing services to the group and their business
affiliates. The network consists of nearly
a thousand routers, firewalls, load balancers and switches.
The group also use Nortel Contivity VPN concentrators. All of
these systems were monitored by a single HP D290 Unix
platform (HP-UX 11.0) running Network Node Manager.
To reduce unwanted network
events I first implemented a network equipment
filter and removed all non-network equipment from the maps. I
subsequently wrote various event handlers to filter out ISDN
calls in particular. I then wrote a system that separately
showed summarized ISDN call information in a web browser,
rather than displaying these NNM's event browser. With
other filters I was able to greatly improve the monitoring
of the network and the frequency of events.
I also wrote an interface between Tivoli
Enterprise Console and HP Openview. This took certain
alarms from HP Openview and forwarded them to Tivoli.
These facilities were written in either
Korn Shell or Perl. The browser programs were either HTML or
