"Efficient monitoring, but reports need improvement"
5/5
What do you like best about Checkmk?

I like the way checkmk is configured, especially compared to 10 years ago. Today we have a nice structure with folders, contact groups, server groups, and corresponding rules. I also like the agents of checkmk because they don't perform evaluations, which is a huge advantage in database monitoring when the server is under load. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

What I like less are the presentations and the reports; they are somewhat cumbersome and, well, content-wise okay, but could be better in terms of presentation. When creating reports and adding content, error messages sometimes occur, and the format often needs to be adjusted so that, for example, the display in the PDF does not have certain tables exceeding one page, and similar, more visual things.

"Scalable Monitoring with Clear Results"
5/5
What do you like best about Checkmk?

I appreciate checkmk's straight-to-the-point monitoring. Even though the UI may look old, the results show clearly. The agents and SNMP are really effective, making it easy to monitor thousands of services on a wide range of network devices and vendors. I find it simple to add or modify new checks based on existing SNMP data. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

Agent downloads in 2.4 are difficult in MSP setups. Hope 2.5 makes it better. Agent downloads via API are from a central site in a distributed setup. The central site might not be reachable by clients being set up as they are in a different network segment. Review collected by and hosted on G2.com.

"Most complete monitoring tool"
5/5
What do you like best about Checkmk?

The simplicity it takes us to go from zero to see everything that is going on in our or clients infrastructures, systems and applications.

There's nothing like CheckMK in the market. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

Honestly, there's not much to say. I believe that it could focus more on the application monitoring itself (APM). SSO would also be a great improvement. Review collected by and hosted on G2.com.

"Checkmk: Modern design and always adapted to current requirements"
4.5/5

Checkmk is always adapted and further developed to meet the current market requirements. There is a clear configuration interface with a modern design where almost everything can be set. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

There is no powerful open-source variant -> the Nagios Core is already very old and aware of multithreading, Review collected by and hosted on G2.com.

"Full-Stack Visibility with Flexible, Expandable Monitoring"
5/5
What do you like best about Checkmk?

It helps getting a full stack overview, not only about your network environment but also deep within application monitoring. Many different systems can be monitored and the software can easily be expanded. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

In large scale environments, it is sometimes too slow, as it has many different components interacting with each other. Also there are fixed limits within several configuration options that do not scale well with large scale environments. Review collected by and hosted on G2.com.

"Quick start thanks to strong Checkmk documentation – ideal for plugin development"
5/5
What do you like best about Checkmk?

I started working with Checkmk for the first time 3 years ago and was able to quickly familiarize myself with its functionality and procedures. The documentation is also very helpful in this regard - especially for plugin development. Review collected by and hosted on G2.com.

What do you dislike about Checkmk?

What bothers me at the moment is that I always have to restart Apache when developing native plugins, for example, to test small adjustments in the Bakery Rule for the plugin. Review collected by and hosted on G2.com.

With 1.6, the windows agent is shipped as an msi. Before it was an exe. Before i installed cmk on a client by a powershell on a central server which, with msi it does not work.
