Zabbix and Checkmk are two competitive solutions in the monitoring sector. Zabbix holds an upper hand due to its open-source flexibility and strong community support.

Features: Zabbix offers automated network discovery, high scalability, and seamless integration with multiple tools, all supported by a vast community. Checkmk provides robust auto-discovery, efficient resource monitoring, and a versatile rule-based configuration for effective performance management.

Room for Improvement: Zabbix could improve its reporting features, ease of use for non-technical staff, and enhance its documentation.

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 alerting system in Checkmk really works properly."

"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."

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

"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."

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

"I really like the auto-discovery feature."

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

More Checkmk pros

"The template system in Zabbix is very beneficial as it saves time in configuration."

"The calculations part is the most valuable."

"The best feature is that Zabbix can report everything, and everything in Zabbix is free."

"The implementation process is very straightforward."

"Setup was straightforward. Initial deployment took two or three months."

"Health and communication links availability."

"We use it to monitor and manage our servers."

"There is less computing power needed for scaling."

More Zabbix pros

Cons

"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 allow running scripts at varying intervals."

"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."

"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."

"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."

"The initial setup is a bit complex."

More Checkmk cons

"The dashboard and the graph section could be a little bit more professional."

"When using this solution in enterprise monitoring, you are able to see that there are some issues with equipment that could be causing a problem. Sometimes you want to make a root command that you do not want to be executed automatically. What we have tried to do is open an SSH session directly from the solution's interface but it is not possible."

"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."

"I would like to see a more flexible mobile client, and better HA out of the box."

"The product could be more secure and more stable."

"The only issue we have had with Zabbix is when we decided to make an update or upgrade."

"I'm using the free version of Zabbix, and I'd like to see more customization options, especially for setting trigger thresholds."

"The event correlation could be better."

More Zabbix cons

Pricing and Cost Advice

"The product is affordable."

"Checkmk is a fairly reasonably priced solution."

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

"We pay the subscription for support by year."

"If you have 20,000 hosts, the support costs around €95,000 for a year."

"It is worth every cent to pay or even study to do your own installation."

"Zabbix is open-source so if one wishes to implement it in-house, they must have qualified professionals to set up and optimize databases, Linux/Unix OS, PHP, Apache, and depending on what is monitored, a full-stack network and systems administrator may be needed."

"Zabbix is an open-source tool, and it's free to use."

"It is a true open-source solution, so there are no licensing costs."

"There is a license required for this solution and we pay annually for our license."

"We purchased Zabbix for a good price, including support"
