Zabbix vs PRTG: The Definitive Comparison

I have been working with Zabbix since 2011, and I am still waiting for it to become as user-friendly and simple as PRTG. In my opinion, PRTG is the simplest monitoring tool that has managed to maintain its simplicity despite having tons of features, although it does come with a hefty price tag!

The main reason I started using PRTG was that the college, where I was running the lab practice for the students, did not have Linux available. PRTG was one of the few monitoring tools that supported Windows. I was surprised at how quickly and easily it was to set up PRTG for the local network.

Key Differences between Zabbix and PRTG

  • Open Source vs Commercial: One of the fundamental differences is their licensing models. Zabbix is open-source and available for free, while PRTG follows a commercial licensing model with a free version that has limitations on the number of monitored sensors.
  • Flexibility and Customization: Zabbix provides more flexibility in terms of customization and fine-tuning of monitoring parameters, making it suitable for complex and specific monitoring needs. PRTG, while user-friendly, may have some limitations in highly customized monitoring scenarios.
  • Ease of Use: PRTG is often praised for its user-friendly interface and ease of setup. It is considered more accessible for users without extensive technical backgrounds. Zabbix, while powerful, might have a steeper learning curve due to its advanced features and configuration options.
  • Scalability: Zabbix is known for its scalability and can handle a large number of monitored devices and metrics. PRTG also supports scalability but might require more careful planning as the number of sensors increases.

Use Cases for Zabbix and PRTG

  • Zabbix: Due to its robust feature set, Zabbix is well-suited for medium to large enterprises that require in-depth monitoring and control over various aspects of their IT infrastructure. It’s also ideal for environments where custom monitoring and extensive configuration are necessary.
  • PRTG: PRTG is a great fit for smaller to medium-sized businesses that prioritize ease of use and quick deployment. It’s suitable for IT teams that want a comprehensive overview of their network health without delving into complex configuration.

Customer testimonials

I implemented Zabbix at a company with 40+ servers without any knowledge of Linux or Zabbix. Took me about 2-3 weeks to setup and monitor servers, printers, switches, Access points etc. Zabbix is powerful and can be complicated, but it can also be very simple if what you want to monitor is simple. Is xx down? Printer running out of ink? Pretty simple to setup when you understand the basics. Later i implemented a setup in Zabbix, which automaticly added monitoring on all new access points added to the network, now that was a tough job, but helped me understanding how powerful Zabbix is and now we’re automating much more

Zabbix has a little bit of a learning curve. Something like PRTG is much easier to setup. But PRTG licensing is very limiting, you gotta think about how you want to spend your “sensors”. With Zabbix, once I wrote a script to install and configure the agent, it was easy. Once I had everything setup, just the default agent templates have so much monitoring, it’s nuts. I think whatever little time I had to spend learning Zabbix, (on the clock) was worth it for my employer, because if I were to setup the same level of monitoring, it would have cost them tens of thousands in PRTG licensing. And because I could just monitor everything without worrying about licensing, I was monitoring stuff I wouldn’t have planned on, and had it catch things before it became a problem.

PRTG syslog and netflow are not really what it is suited for. You can put the data in there but getting actionable information out is difficult. It really is designed as a monitoring/health management tool and not a comprehensive ELK tool.

PRTG any numbers it can collect that it knows how to set up and collect, it’s da bomb, anything that it’s bread and butter, it’s amazing. Out of the box, this includes switchport stats, wmi, ipmi, service monitoring, tls monitoring, uptime monitoring, system health, even email gateways, etc… Anything that can be monitored visa SMTP, it’s da bomb. You may have to to do some OID lookups yourself and copy paste some OID fields, but then you’ve your monitoring the amperages on all the banks on the PDUs, datacenter temperatures in every rack (using the environmental MIB in every switch, any number re-portable by SNMP by any device. Basically, it quickly gets you 95% of what you need, with 5% of the work – just autodiscover and tweak. Then, you come to anything that’s a number, that PRTG doesn’t know how to get. So for that you either write custom probes, etc.. (I do a lot of Advanced HTTPS Push Sensors). So for things PRTG knows nothing about – (Storage free on an enterprise array, channel utilization on another device, outside temperature pulled from a weather service, etc…) A snip of python for each, it’s really easy. The things you’ve mentioned – netflow and syslog are not PRTG’s bread and butter. They’re strangely fitting strapons. They provide some value, but they’re both very limited compared to dedicated products for each. I would never recommend someone buy PRTG /for/ netflow and/or syslog. I have 12,000 active sensors of PRTG’s bread and butter, some penut butter and jelly and I couldn’t be happier. It also contains pickles (netflow and syslog), and while it’s nice to have light pickle from time to time, its not something I want daily, and in no way diminishes the bread and butter. If I wanted pickles all day, I might look somewhere else. (At the risk of stretching the analogy way, way too far…)

Zabbix can be a bit of a pain to set up (tho massively improved since the 1.x days), but it’s just… perfect. You can create “Low-level discovery” rules which scan the device for specific OIDs and values and can then apply template and even put it in the desired groups. And creating a map of the network topology is extremely satisfying, as you can animate/colour the various elements, or even show small summaries of traffic/utilization per link. Lots of people underestimate how neat this feature is as a high-level overview for your network.

PRTG kinda… works. I mean, it’s easy to get going and, if you have a static environment, doesn’t require looking after. But f*****g hell… Any and all automation is just not there. The absolute worst is its scan-feature – it just picks up any interface, even those which don’t have anything connected. There’s no way to filter (Like, only interfaces with a specific word in the description).

Zabbix and PRTG are both popular network monitoring tools. Zabbix is open source and offers more features and flexibility, while PRTG is more user-friendly and easier to set up.

Zabbix is a good choice for large enterprises with complex monitoring needs. It offers a wide range of features, including real-time monitoring, alerting, visualization, and capacity planning. However, Zabbix can be complex to set up and manage, and it requires some technical expertise.

PRTG is a good choice for small businesses and organizations that need a simple and easy-to-use monitoring tool. It offers a wide range of sensors and features, and it is easy to set up and configure. However, PRTG does not offer as many features as Zabbix, and it may not be suitable for organizations with complex monitoring needs.

In the end, the best choice for you will depend on your specific needs and requirements. If you require a powerful and flexible monitoring tool with a wide range of features, Zabbix is an excellent option. Alternatively, if you need a simple and easy-to-use monitoring tool that is straightforward to set up and manage, and you have the budget for it, then PRTG is a suitable choice
