Network Monitoring VPS with Nagios, OpenNMS, Zenoss and More

by Chinonye on July 5, 2011

NagiosWith great cloud computing power comes a great deal of responsibility – mostly to ensure that the technology is being used as efficiently as possible, and that it is delivering the right performance.

For many companies, the idea of network monitoring in the cloud using a virtualized server is a foreign one. Monitoring at a physical, local level was always done in a certain way, a way that is no longer applicable once a move to a virtual or cloud-based server has been made. Fortunately, a number of network monitoring VPS tools are now available to help make the jobs of company IT professionals easier and to let managers and team leads see exactly what is going on in a company’s infrastructure at any given moment.

Such tools give companies the means to ensure that their resources are properly portioned out and that they are delivering the kind of performance they should. Among these options are the popular choices Nagios, OpenNMS and Zenoss, which all are aimed at the same goal – monitoring a network and providing a visual display of performance measurements that can be easily understood.

All three of these options can be installed on a local server or host machine and will perform their network monitoring from there. But what many companies are now choosing to do with these monitors is deploy them as network monitoring VPS options instead, installed on a VPS server and looking inward to a company’s uptime, network use, and overall efficiency. When installed on a VPS, network monitoring software will be unaffected by changes to the local network, and can safely report on the network status of the company without any possibility of accidental bias.

Take Nagios VPS installations as an example. Nagios was launched in 1999 and is designed to help businesses identify and resolve IT issues before they become serious problems. The company runs training seminars online for their product and will be holding its first-ever Nagios World Conference in North America in September of 2011.

Zenoss is another popular network monitoring tool, and one that is focused on the needs of enterprise IT, as well as the shift in the industry toward IaaS solutions. The company offers real-time, unified service operations reports that can be run for virtual, physical or cloud-based systems, and are intended to allow the monitoring of an entire network from a “single pane of glass”, according to the company Web site.

OpenNMS is the first open-source networking managing tool that has reached Enterprise caliber. Started in 1999, the project was registered on SourceForge in 2000, and features no licensing fees, subscriptions or different versions – what is offered is free, and designed entirely under an open-source model.

These applications are designed to be easy to use, and a Nagios VPS option will require nothing more than a system having a Linux or UNIX variant installed as its OS and that it has a C compiler installed.

In addition to these popular options, others like Cacti are breaking into the monitoring space as well. Cacti is a frontend to RRDTool and is meant to create graphical representations of information that are then populated in a MySQL database. This makes it easy for IT managers to quickly examine data reported from a network monitoring VPS solution and decide how best to act on it.

Network monitoring that is simple, effective and VPS-based is the new way for companies to keep track some of their most crucial resources.


If you’re a company that’s making any headway in the new global market, chances are that you have a website. In order to make the most of it, it’s time to start thinking about making the move – migrating your information to a new Content Management System (CMS).

When most businesses think about their static website, “good enough” is the phrase that comes to mind. Often, the notion will reign that so long as pertinent content is located on the site, it is fine to continue as-is, using the same hosting CMS and not worrying about “flashy” applications that other websites have. The truth is that not only do Internet users scan very few of the top pages of any search engine query they make, but that they will leave a Web page within seconds if it does not appear to have the information they want, or if it is hard to navigate. An outdated CMS, or a lack thereof, means a website that may be doing you more harm than good.

There are thousands of CMS options on the market, most of which are free to use. Three of the top CMSs currently in use are WordPress, Joomla, and Drupal, which out of the top 100,000 sites on the Web are used by 52.75%, 16.47%, and 8.15%, respectively. Together, they account for over 77% of all CMS usage in the top 100,000 and over 76% in the top 1 million.

Each of these three CMS types have a number of features in common, most notably their ability to provide easy updating options for anyone tasked with maintaining a static site. Once installed, controlling not only what is posted but when and where it is posted on a site is a simple process, thanks to a wide range of applications, modules and widgets that can be installed on any Web page to streamline its use. Downloading a WordPress hosting option, a Drupal hosting choice or Joomla hosting package is easy – simply go to the website of the CMS and click “download.” The communities behind all three systems are extremely vocal, and can provide excellent support to any company that is looking to migrate their static site.

Getting a site up and running under WordPress hosting is easy, and many argue that it is impossible to beat the ease with which content can be posted on a WordPress page. Drupal hosting is known for being flexible and robust, and those using Joomla hosting will find the community is committed to constant improvement of the CMS – the alpha version of 1.7 was released on June 6, 2011 for testing. Rather than paying a designer to create a website with a custom CMS that is bulky, big, and will never be updated by anyone in the company, a smaller, streamlined CMS like WordPress, Drupal or Joomla can let a company move their static site easily, and also clean up any cluttered content that exists. If you have a static or proprietary site, now is the time to make the switch, download a new CMS and make the upgrade.

A number of popular websites currently use each of these free CMS programs – is powered by Drupal as well as a number of other Government websites, the IHOP website as well as that of the Guggenheim are powered by Joomla, and thousands of notable sites are powered by WordPress, including Forbes, TechCrunch, and many more. For any static Web page application and maintenance, a Drupal, WordPress or Joomla hosting option can help to ensure a better Web presence and increase a company’s usability of its own Website.

You know you’ve made it big when you start hosting your own World Conferences! Congratulations, Nagios!

I love the straightforward quality of OpenNMS, as well as its ease of use–and the fact that it’s free ain’t bad either.

I’m not clear on what Zenoss is referring to when they say “single plane of glass.”

Stoddard July 12, 2011 at 8:41 PM

I think “single plane of glass” just means you can see it all at once on any screen.

I’ve been testing all of these over the past few weeks for an SME, unfortunately openNMS was hard to navigate, Nagios to difficult to configure and maintain.. the only two that came close to offering a useable interface was Zenoss and Zabbix..

I didn’t realize openNMS was hard to navigate, K. It’s good to know Zenoss had something of a useable interface, though…how did Zenoss measure up in other areas?

SunnyT January 31, 2012 at 7:27 AM

I prefer ZenOSS because of the easy integration of other collectors than the local one. The primary checks through SNMP and WMI are setup automatically. Including mibs for unknown devices is straight forward. e mail notification and escalation works well.
