CHECKMK have the real time alerting function with various plug in available. It is used from the server ping alert to the database alerting function. Review collected by and hosted on G2.com.

Need some tuning skill as there are plenty of alerting feature/services which need to prevent using default value. Else, ones will keep on receiving the alert but not knowing what is the alert mesage related to. Review collected by and hosted on G2.com.

There is so much power and capability - choosing which to use / implement is the toughest part. Review collected by and hosted on G2.com.

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.

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.

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.

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.

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.

It's fast and easy to deploy. I started without any training or support. The docs are very clear and it's easy to find content about it. The documentation really improved from last year with more examples. Review collected by and hosted on G2.com.

There's no Brazilian Portuguese support yet.

Don`t support multiple timezones Review collected by and hosted on G2.com.

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.

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.
