What do you like best about checkmk?

Checkmk excels in its comprehensive monitoring capabilities, covering everything from network devices and servers to applications and cloud services. The auto-discovery feature is a huge time-saver, and the customizable dashboards provide excellent visibility into our infrastructure's health. The scalability is also a major plus, allowing us to monitor a growing environment effectively. The check plugin ecosystem is vast, meaning we can monitor almost anything we need to. Review collected by and hosted on G2.com.

What do you dislike about checkmk?

While incredibly powerful, the initial learning curve for some of the more advanced configuration options and custom check development can be a bit steep for new users. Sometimes, troubleshooting very specific or niche monitoring issues can require a deeper dive into the documentation or community forums. The UI, while functional, could benefit from some modernization in certain areas to improve the overall user experience, especially for less technical users.

What do you dislike about checkmk?

There is not much negative I can tell. Tuning Checkmk performance, especially in a distributed setup, can be somewhat tricky. Review collected by and hosted on G2.com.

What problems is checkmk solving and how is that benefiting you?

Checkmk comes with a bunch of pre-defined Hardware, Software, Application checks it supports. All our SAP and MSSQL Database servers, Vmware ESXi hosts, Mid-range Storage Systems as well as Network devices (Switches, Firewalls, Routers, WLAN-Controllers) and Media devices (mostly monitored via SNMP) can be seamlessly monitored. Most of the services and metrics are discovered automatically. Warning / Critical thresholds are automatically set at reasonable defauts. This saves a lot of time for manual configuration.

What do you like best about checkmk?

We have been using Checkmk for many years.

The installation itself for both the server and the agent is very simple and quick.

The default limit values set are perfectly adequate for a standard environment.

It is impossible to imagine our everyday life without Checkmk. My first step in the morning is to check the dashboard to see if there are any problems or faults.

The community is also very helpful and you can already find posts and solutions to most problems in forums.

I can only really recommend Checkmk to everyone. Review collected by and hosted on G2.com.

What do you dislike about checkmk?

There is only one negative point regarding Checkmk.

So far there is no support for ARM CPUs. However, it has already been announced that this is already being worked on. Review collected by and hosted on G2.com.

What problems is checkmk solving and how is that benefiting you?

Since we started using Checkmk, we have had fewer critical problems because we are warned in advance that a problem is about to occur.

Checkmk also allows us to localize problems more quickly. Review collected by and hosted on G2.com.

What do you like best about checkmk?

Ease of use in setup. It was probably easier for me after years of command line administration. The product is very versatile. I was blown away at being able to make my own custom dashboards. Implementation was pretty easy and again I was familiar with cli installation. I have been leaning toward Debian lately and it runs on an old server just fine.

What do you dislike about checkmk?

There are still areas that need worked on. The email integration is a little awkward since you have to go command line Review collected by and hosted on G2.com.

What do you like best about checkmk?

It's an easy solution to install and then to maintain.

Configuration is all in the UI which make very easy to setup.

If you can't find the plugin you want, just write it as it's quite simple with python and the doc.

There is a strong community both on the forums and the open source code side. If you decide to go with the paid edition, it's not expensive as the competitors.

Most likely the monitor everything tool.

Support is quick and provides hot fixes if needed.

Each release so far have been smoother and smoother

After more than 10 years using it I am still sold on the product and I don’t have regrets. Review collected by and hosted on G2.com.

What do you dislike about checkmk?

When you go into the solution for the first time you have to adapt to the rules logic which can be hard at times.

Also with upgrades you sometimes have to redo what you did because a new better way of things got released.

It can take time for them to fix issues if you didn't pick paid support. Review collected by and hosted on G2.com.

What problems is checkmk solving and how is that benefiting you?

Check mk allow you to monitor your network, servers, ac, pdu... but with plugins you can basically monitor everything you like : your gazmeters, a web page, a webcam...

Say goodbye to the N amount of appliances and dashboards you had before and get all that in one place. Review collected by and hosted on G2.com.

What problems is checkmk solving and how is that benefiting you?

Before Checkmk, we were blind. We had no visibility into our IT infrastructure, and we were constantly reacting to problems as they happened. This was a major pain point for our team, and it was costing us a lot of time and money.

Then we implemented Checkmk, and everything changed. Now we have complete visibility into our IT infrastructure, and we can proactively identify and resolve problems before they impact our users. Review collected by and hosted on G2.com.
