Key Differences between Zabbix and Checkmk

When comparing Zabbix and Checkmk, several key differences emerge:

  • Scalability and Complexity: Zabbix excels in handling large-scale environments with its efficient data collection and great storage mechanisms. Checkmk, however, provides a more streamlined experience, making it ideal for organizations seeking simplified management and quick deployments.
  • Ease of Use: Zabbix offers a user-friendly interface, but Checkmk’s interface and configuration processes are often regarded as more intuitive and beginner-friendly.
  • Monitoring Approach: Zabbix primarily focuses on infrastructure monitoring, while Checkmk extends its capabilities to include application monitoring and business process monitoring.

Use Cases for Zabbix and Checkmk

The choice between Zabbix and Checkmk largely depends on your use case:

  • Zabbix Use Cases: Zabbix is well-suited for organizations requiring extensive network monitoring and in-depth performance analysis. It is ideal for IT teams managing complex infrastructures that demand scalable monitoring capabilities. Zabbix is also a good choice for those who want a 100% software solution without any enterprise-paid modules.
  • Checkmk Use Cases: Checkmk shines in environments that demand holistic monitoring, including infrastructure, applications, and services. However, it is important to note that out-of-the-box holistic monitoring with Checkmk will require the purchase of additional modules. These modules can be expensive, so organizations should carefully consider their needs before making a purchase.

Licensing and Pricing

Zabbix is open-source software, which means that it is 100% free to use and distribute. Furthermore, Zabbix SIA, the company behind Zabbix, provides paid services such as support, training, and custom development. These services are typically used by larger organizations that need more advanced monitoring capabilities or want to receive support from the Zabbix team.

Checkmk provides both open-source and enterprise editions. The open-source version delivers robust monitoring capabilities, while the enterprise edition adds advanced features and dedicated support.

Customer testimonials

Switched from Zabbix to CheckMK to reduce admin effort.

Zabbix is really great but needs some attention regarding updates, database etc. The Zabbix item prototypes are simply awesome when you know how to create them and work with them. I invested quite some time to get all my devices monitored the way I wanted to.

CheckMK is as easy as it gets. Installing / upgrading is dead simple. Monitors my whole infrastructure out of the box. Adding news devices happens automatically and just works.

Only thing that is really a PITA: If you want to monitor your server volumes, you must install the CheckMK agent. Zabbix gets VM disk info directly via the VMWare monitoring. CheckMK doesn’t.

So with Zabbix I had a handful of agents installed on my servers to get more detailed infos like running services etc. With CheckMK I have an agent running on all machines.

On the other hand, CheckMK Agent updates automatically on all machines and this works 99% of the time.

Performance wise I have to say that zabbix and checkmk are on par. But as I said, CheckMK needs way less effort so set up and maintain.

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

My preference is Checkmk

While up front it can be easy, it can go really really really deep if you want to.

Handles push, pull, agent, agentless, snmp (all), custom, etc. Can do forecasting, reports, dashboards, but really, you don’t have to even do all of that. Handles events, syslogs, snmptraps. Lots of notification options. Allows end users to get notified for “whatever” they choose if they want. Has flap detection. Ability to set scheduled downtimes for hosts as well as individual services. Can monitor clustered services. You can also create business logic rules for disparate services (e.g. “thing” is up if this and this and at least one of this is up, etc..).

I haven’t found anything I could not do with Checkmk.

At work we’re monitoring about 10,000 services across 170 hosts and that’s not including all Windows log events, snmptraps, syslogs, etc.

Zabbix is pretty good. And FLOSS. I don’t love the Web UI – I came from Zenoss when it drifted closed source. I preferred some things about Zenoss, but we have made Zabbix work. It’s real simple to get ping monitoring going, and the agent makes Windows / Linux / whatever monitoring easy. There are also templates out there in the community for all sorts of stuff like I think ubiquiti edgeswitches etc that add more.

I think it’s the best one for free right now, but there are certainly things I’d like to be different about it in the UI.

Zabbix and Checkmk are both powerful monitoring solutions with a wide range of features. The best choice for you will depend on your specific needs and requirements.

Zabbix is a good choice for organizations with complex infrastructures and the desire for extensive customization. It is scalable, flexible, and efficient, and it has a large library of preconfigured templates. However, it can have a steep learning curve and dashboard customization can be complex.

Checkmk is a good choice for organizations that want an easy-to-use monitoring solution with comprehensive monitoring capabilities. It has a user-friendly interface. However, it might be overkill for smaller environments and certain advanced features are limited to the enterprise edition.

I don’t think that you can go wrong with one or the other!

Ultimately, the best way to decide which monitoring solution is right for you is to try both Zabbix and Checkmk and see which one you prefer.
