PRODUCT OVERVIEW

PRTG vs Open Source: Optimize monitoring with PRTG

Paessler PRTG makes IT monitoring easier. You think this is a bold statement, then think about the following: Almost all of the open-source alternatives such as Nagios, Zabbix, or Prometheus require you to have extensive Linux expertise. PRTG on the other hand is quick and easy to set up, and you can start monitoring your network devices, servers, and applications without going through pages and pages of technical documentary.

While open source monitoring solutions like Icinga are flexible, they are complex and need ongoing maintenance to really shine. PRTG on the other hand is an all-in-one package with all its features and sensors ready to use. Say goodbye to the need to search for plugins or struggle with complex configurations. This saves time during setup and in the months and years to come.

PRODUCT OVERVIEW

IT experts agree: Paessler PRTG is a great solution for IT infrastructure monitoring

“All-around winning

IT Brief

“The real beauty of PRTG is the endless possibilities it offers”

ITPro

“PRTG Network Monitor 
is very hard to beat”

4 reasons why PRTG is a better choice than open source monitoring solutions

icon setup

Simple setup and operation

PRTG is an user-friendly network monitoring software with an easy-to-understand user interface and straightforward installation. The auto-discovery feature maps your network automatically, enabling quick deployment on Windows and Linux. 

This is different with open-source alternatives like Nagios or Icinga, which often demand extensive setup and API customization, slowing down your monitoring implementation and increasing the learning curve.

icon monitoring capabilities

Monitoring capabilities

PRTG monitors your entire IT infrastructure monitoring with technologies like SNMP, NetFlow, or WMI. Whether you want to track your network performance, bandwidth, and internet traffic, monitor server resources and business applications, or oversee routers, switches, firewalls, and cloud services: you will find the right tool for your use case.

icon reporting

Built-in visualization and reporting

PRTG provides you with customizable dashboards and integrated reporting. No more need for you to download, install and configure a bunch of additional tools and plugins to achieve the same thing with an open-source alternative. 

The different sensor states are easy to understand thanks to their color-coded statuses and make it easy to identify and resolve network issues. It never was easier to create graphs and reports for bandwidth usage, network performance, and more.

icon support

Dedicated support and resources

While open-source communities can indeed be helpful, they often lack timely, direct support if your are having a critical issues. Paessler offers a dedicated customer support and an extensive knowledge base additional to the technical documentation. 

This kind of professional assistance is crucial, especially for larger teams and businesses that need guidance on more complex monitoring configurations or want to troubleshoot network issues.

PRODUCT OVERVIEW

”As an international company, PRTG is ideal for us. If something went down half way across the world, we wouldn’t be woken up – we can rely on PRTG to identify the problem and alert us before it occurs – enabling the right person, in the right time zone to resolve the problem. At the end of the day, if we’re to provide an internal network experience for our employees that meets expectations, we need a tool like PRTG to be successful.”

Barry Kelly, Systems Engineer
Skyscanner

“All our production and business processes depend on SAP. But, of course, IT and production systems also play a crucial role in securing these processes. By incorporating SAP, production, and IT into one centralized monitoring system, we can quickly detect critical drops in performance and identify the causes of these issues. In fact, thanks to PRTG and itesys, this couldn’t be any easier.”

Andreas Schmidt, Senior Systems Engineer
Truma

“We set up PRTG to read the event logs of the service. If the service is no longer able to access the database, then this information is recorded in the service’s EventLog and immediately detected by PRTG via WMI. The software then automatically triggers a script that restarts the service. The service reestablishes its connection to the database and the problem is solved.”

device overview

PRTG vs. other monitoring tools

We also compared PRTG with other monitoring tools:

PRTG vs. Nagios

The basic version of the open-source tool Nagios is free of charge. But most users spent many hours to set up and customize the tool. In case of problems, browsing through forums is often the only solution.

Comparison with Nagios

PRTG vs. Zabbix

Zabbix is open-source software with a strong community support. But it requires lots of manual configuration work to install and set it up. You also need to install agents on the monitored systems.

Comparison with Zabbix

PRTG vs. Checkmk

Checkmk is a comprehensive network monitoring tool, but it uses open-source add-ons for some functions. This means additional work in setting up, operating, and maintaining the monitoring systems.

Comparison with Checkmk

PRTG vs. Icinga

Icinga is an open-source monitoring tool offering flexibility but requiring advanced technical knowledge. Its setup and maintenance can be complex, especially for teams lacking dedicated Linux expertise.

  • If you want to monitor an unlimited number of remote locations and networks at no extra cost.
  • If you prefer high scalability and a software tailored to large, complex environments.
  • If you want to get real-time alerting, custom notifications, and automated reporting.
  • If you want to have the choice between an on-premises or cloud-based solution.
  • If you want a straightforward licensing model at a comparatively low price.

Open Source might be your choice:

  • Pros: Free to download, highly customizable
  • Cons: Complex setup, steep learning curve, often require additional tools

PRTG:

  • Pros: User-friendly, all-in-one solution, scalable pricing, professional support
  • Cons: Less customizable than some open-source options
How does the PRTG pricing compare to open source alternatives?

While open-source solutions are free to download, they often have hidden costs in maintenance or professional consulting due to their complexity. PRTG offers transparent, scalable pricing with a free version for up to 100 sensors, flexible licensing for growth, and all-inclusive pricing with no hidden costs for features.

What sets PRTG apart from open source monitoring tools?

The main differences are:

Ease of use: PRTG is easier to use and you can finish the setup in a matter of minutes.

Costs: Open-source tools are free to download but may have hidden costs in terms support, consulting, or additional tools needed. PRTG has a clear pricing structure with a free version available.

Customization: Open-source tools often offer more extensive customization options, while PRTG provides a good balance between customization and out-of-the-box functionality.

Support: Using PRTG includes professional support, while open-source tools typically rely on community support.

What monitoring capabilities does PRTG offer?

PRTG provides you with comprehensive monitoring for network devices, servers, applications, and cloud services. Key features include network performance monitoring, server monitoring, application monitoring, infrastructure monitoring, and cloud monitoring.

How does PRTG compare to open source monitoring tools in terms of ease of use?

PRTG is usually more user-friendly. With its simpler setup process compared to many open-source alternatives it also values your time. Open source tools often require significant Linux knowledge and manual configuration, while PRTG provides auto-discovery and intuitive dashboards, reducing the learning curve substantially.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
