Open Source Network Management Software

In one of my previous post, Open Source Business Solutions - ECM, CRM, CMS…, I wrote about Hyperic, which is the open source network management and monitoring tool that I used. Recently I got to test out other open source network management software. The ones that I have tested are Zenoss, Nagios, and OpenNMS.



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.



I heard Nagios from a friend. He is satistifed with Nagios after using it. As quoted from the site, Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external “plugins” which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.).

I have not really test it out comprehensively but looks like it got almost the same features as Zenoss and Hyperic.


OpenNMS claims to be world’s first enterprise grade network management platform developed under the open source model. It consists of a community supported open-source project as well as a commercial services, training, and support organization.

Just my personal flavor, the ones that I preferred are

  1. Hyperic or Zenoss
  2. Nagios
  3. OpenNMS
  4. MRTG
