Free vs. easy to use and time-saving:
Why an open-source tool might not be the most cost-effective choice
At first glance, Nagios open-source software seems considerably less expensive than PRTG. After all, why should you pay for something that you can get for free?
Nagios saves you money but costs you time & effort
When it comes to software that you need to customize to meet the specific needs of a company, its purchase price is only a small factor if you consider its overall costs.
The initial setup of Nagios already takes a lot of time. Moreover, you can only install the tool’s free edition via Linux/Unix and all devices and checkpoints must be added using shell commands.
It is not uncommon for the setup to take several days, even for experienced Linux users. And if you need to customize your Nagios configuration later, you can count on spending an enormous amount of time and effort to get it done.
Choose PRTG, a tool which is ready to go in minutes
PRTG is configured in just a few quick clicks. Its auto-discovery function detects all devices and services in your network automatically and creates a first set of so-called PRTG sensors.
Adding, processing, and deleting sensors is straightforward and extremely intuitive thanks to an easy-to-understand user interface.
The time and energy that you spend configuring Nagios can quickly let operational costs go through the roof. At the end of the day, the seemingly free open-source tool is not really that inexpensive.

PRTG vs Nagios: All the features you need in an easy-to-use tool vs. low level of usability
Scalability can become complicated in Nagios
Nagios can be effective for small networks, and yes, the very basic version Nagios Core is available for free. It gets more complicated, however, if you need to manage larger environments. To set up Nagios correctly, you will need a lot of time and effort before reaching a professional standard, either by changing the source code or by using additional hardware to scale the solution.
PRTG right from the start, no forums needed
With PRTG, you won't waste countless hours reading forums and editing configuration files. After installing PRTG in just a few seconds, the smart setup assistant guides you through the setup and initial configuration. You can also use the auto-discovery feature to automatically create a comprehensive set of sensors for your entire network.

We would not put it as hard as Jonah Kowall does in his blog article: "Got Nagios? Get rid of it." And: "The level of usability and sophistication of the product (Nagios) is pretty much zero." But we, too, think that Nagios’s user interface is not very good and it’s definitely not very intuitive at all. PRTG, on the other hand, comes with a state-of-the-art, responsive web interface as well as smartphone apps for monitoring on the go.

3 more reasons to use PRTG as a alternative
Have more time for your core responsibilities
As a system administrator, you must dedicate a great deal of time to the maintenance of your IT infrastructure, as this is the backbone of your company.
So let’s be honest: you could use the time that is needed to set up and maintain the operation of open-source software like Nagios or Zabbix in a much more efficient manner.
With the automated monitoring of PRTG, you are free to deal with other important tasks in your daily business.
Benefit from expert technical support
By purchasing a PRTG license, you will get free maintenance and support for one year. If you have a problem or question, our technical support team will respond within one business day.
Moreover, our extensive Paessler Knowledge Base offers you precise answers to almost any issue that you might have. This way, you won’t have to spend hours browsing through online forums.
With PRTG, you’ll save both time and worry!
Use PRTG even without a technical background
With Nagios, it can take days or weeks to get used to and customize the open-source software to meet the specific demands of your company and network.
People who configure and use Nagios need to have deep technical knowledge to do so. And if a Nagios expert leaves the company, other colleagues will usually have a hard time understanding how to use the tool.
By contrast, PRTG is also extremely easy to use for non-techies – even colleagues who were not involved in the setup process have no trouble getting the hang of the tool and the monitored network environment.
"PRTG totally blows away similar and popular server-based monitoring software, for example Nagios and Pandora FMS. Both of these competing applications were difficult to set up and use, and the interfaces felt poorly designed, hokey, and I couldn’t imagine using the interfaces of these products on a daily basis.”

Tired of using Nagios? It’s easy to switch to PRTG
If you currently use Nagios and wish to switch to PRTG, you’ll have no trouble doing so. Even larger network environments are usually configured in PRTG within a few short hours.
Thanks to the PRTG auto-discovery feature, you can quickly integrate your entire network into your monitoring setup – no matter from which manufacturers your network devices are.
Device templates are extremely useful for configuring several devices at the same time. As a result, a few clicks suffice to configure an entire IT environment.
Many of our customers migrated from Nagios to PRTG because of the easiness and flexibility that PRTG offers. Read how Peak Internet or NetMass employed PRTG Network Monitor instead of the open-source tool Nagios:
Peak Internet prides itself on offering the best technology and service to its customers. While many other ISPs are not bothered when their customers alert them to an outage, Peak wanted to do better. In the past, Peak Internet employed a variety of network monitoring tools (Nagios, Smoke Ping, Monit, Zenoss, What’s Up Gold, and Zabbix). "We were looking for a single point of monitoring for our whole business at the best cost, with ease of use," said David Placko, Chief Technology Officer at Peak Internet. "PRTG was a real winning solution for us."
Nagios, designed for the Linux operating system, worked well in some configurations for NetMass. But soon there were concerns. "The NSClient++ solution with Nagios did not do as well for monitoring remote Windows servers," states Stephen Perkins, President and Chief Technical Officer of NetMass. "It was also very complex to manage and configure the multi-site plug-ins that we needed. Often, new services would not get properly configured in Nagios because of the extra overhead. Over time we just wanted an easier solution."
