Recently I got to test out other open source network management software. The ones that I have tested are Zenoss, Nagios, and OpenNMS.

Zenoss

I can see the Zenoss and Hyperic are both very good network monitoring software. Zenoss is writeen in Python. Even though I do not know Python, looking at it I think it is very easy to be customized. Zenoss provides a single, integrated solution for monitoring your entire IT infrastructure: network, servers, applications, across the full lifecycle: inventory, configuration, availability, performance, events, logs and alerts.

Nagios

Several years back I was programming a network utility that needs an index relating IP network numbers to network names and identities, for class A, B and C networks, I found this list compiled from the Internet.

I know that you can always use whois, or some online website to achieve the same thing. MaxMind even has a collection of GeoIP APIs that can be used. There are even companies provided IP to city/region/country mapping database. However the list here is more details as it provides the identities as well.

The list is extracted from the whois database at the Internic. As of December 22, 1997, control of IP network allocation has passed to Arin (American Register of Internet Networks). There are similar organisations for European (www.ripe.net) and Asian-Pacific (www.apnic.net) networks.

As an example, see below
