Executive SummaryUpdated on Jul 6, 2025

Zabbix and Checkmk are both open-source monitoring solutions competing in the network, server, and application monitoring category. Zabbix appears to have an upper hand due to its flexible and comprehensive feature set.

Features: Zabbix is known for its flexibility, auto-discovery, and scalability. It supports features like Low-Level Discovery and provides extensive integration options. Checkmk is valued for its automatic discovery capabilities and its ability to integrate seamlessly with other systems.

Room for Improvement: Zabbix users often desire enhancements in its reporting functions, user-friendly interface, and support for modern workloads like containers. Improvements in automation and integration are also suggested. Checkmk could enhance its integration capabilities and make its documentation more user-friendly to improve accessibility.

Ease of Deployment and Customer Service: Zabbix offers flexible deployment options, including on-premises and hybrid cloud environments, but non-experts may find the setup complex. Its community support is appreciated, though less direct than Checkmk's structured support services. Checkmk stands out for its easy on-premises deployment and effective setup process.

Pricing and ROI: Zabbix is an open-source platform with no licensing fees, allowing significant cost savings, particularly for large-scale deployments, and generally offers a high ROI due to its comprehensive features. Checkmk is considered affordable, with its enterprise edition's cost being justified by the features and support offered compared to other solutions. Both products offer highly cost-effective solutions with significant value.

Application performance and System monitoring at Agos

A reasonably priced tool for system and application monitoring

The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The initial setup of Checkmk was easy...It is a very stable solution."

"Checkmk helps me compare data and foresee issues."

"I really like the auto-discovery feature."

"Overall, from one to ten, I rate Checkmk a nine."

"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."

"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."

"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"We can monitor multiple sites using the product."

More Checkmk pros

"The performance and bandwidth are valuable features."

"It is a great product. The SNMP protocol tracking feature is good. I really like how it tracks SNMP. The alerts are also great."

"Templates are good. We download them from the official Zabbix site or the community. If the information we need isn't available, we create custom templates based on client requirements."

"The product is very stable."

"We use Zabbix to monitor our organization's IT infrastructure and workstations. We don't use Microsoft Intune since it's expensive. The tool's real-time alerting system has proved crucial for us, particularly when a new device joins a network that is not one of our own devices. It notifies us about the presence of this new device, allowing us to investigate further. Additionally, it alerts us about disk usage, memory usage, and the software installed on the machine."

"Zabbix has high scalability. I would rate it a nine out of ten."

"The most valuable feature is network traffic monitoring."

"Zabbix is an excellent performance monitoring tool."

More Zabbix pros

Cons

"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."

"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."

"In Checkmk, the documentation can probably be improved a bit more."

"Checkmk does not allow running scripts at varying intervals."

"It is easy for tech-savvy people, but newcomers might find it intimidating."

"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."

"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."

More Checkmk cons

"It could be more stable."

"They should open an SSH session from the web interface."

"Its UI needs to be improved a little bit more so that an end-user is also able to handle it. I can handle it, but others should also be able to handle it in a better way. It becomes complex when we are growing and need to add proxies. We need more scalability features and documentation for different use cases. A lot of articles are available, but they need to be in proper documentation. For example, when you have thousands of servers that have to be monitored in different regions of the world, there should be some kind of documentation to describe how you can create proxies and add them. Sometimes, when you are using the database, it can get overloaded. When the network is growing, the number of transactions becomes very high, and the database gets overloaded. There should be information about how to reduce the load on the MySQL database, which is what Zabbix is using. The market is growing a lot, and it should be enhanced for a lot more things. We are currently bringing enhancements at our end for different use cases. For example, when dockerization is going on, how can we check the logs inside the Dockers. We should also be able to monitor and check the number of logins and add features such as SSO login and two-factor authentication as a protocol. These are the security features and concerns that we have to deal with. Currently, we are developing modules to add features to Zabbix, but they should also work on these features."

"Implementing Zabbix is difficult. I've deployed many solutions over the years, and Zabbix is the hardest to implement. You have to do some development to get it to work with IBM, Micro Focus, or HP products."

"The solution needs to add remote features."

"The GUI could be more intuitive. Also, we'd like streaming telemetry. Zabbix might have this feature, but I haven't seen it yet. It took us a long time to get started because the documentation isn't very descriptive. We had to go through various sources like YouTube and forums to get this solution working."

"Zabbix is not easy to configure, and upgrading is also an issue."

"There is a bit of a learning curve during installation."

More Zabbix cons

Pricing and Cost Advice

"Checkmk is a fairly reasonably priced solution."

"The product is affordable."

"The price of Checkmk is cheaper compared to other enterprise products."

"This is an open-source solution that can be used free of charge."

"It's free software released under the GNU/GPL license."

"We pay the subscription for support by year."

"Zabbix is a free solution but the support contact costs money."

"There are no licenses."

"I was using the free, Community Edition."

"It is open source. If you want to have a subscription or official support, you can pay for it. They have different plans, which are not that expensive. The plans are based on per monitoring server, not per monitored equipment. So, it is not at all expensive, and you can also live without the support if you want a cheaper option."

"The product is an open source and free solution."
