Checkmk - Your complete IT monitoring solution

Checkmk is available in several editions. The Checkmk Raw Edition is free and 100% open-source. The Checkmk Enterprise Edition includes several additional features and professional support from the authors, billed annually. A demo version is freely available for testing the Enterprise Edition in a non-production environment.

Checkmk can be installed on Linux servers via DEB and RPM packages found on our downloads page. The Enterprise Edition is also available as a virtual or physical appliance. The following short installation guides show how you can easily set up Checkmk and begin monitoring.

Please visit our website for more details.

Getting started

Please have a look at the beginners guide on how to get started with Checkmk.

Want to contribute?

Thank you for your interest in contributing to Checkmk! Unfortunately, due to our current work load, we can at the moment only consider pure bugfixes, sorry for that. Thus, any new pull request which is not a pure bugfix will be closed. Instead of creating a PR, please consider sharing new check plugins, agent plugins, special agents or notification plugins via the Checkmk Exchange.

For pure bugfixes, have a look at our contribution guidelines.

Building on your own packages

It is highly recommended to use the prebuilt Checkmk packages we provide. But if you really want to build your own packages, you either need to download the source packages from our website or check out the Git repository.

To prepare your system for building, you need to execute this command:

make -C omd setup

This will install the missing build dependencies, at least if you are working on a supported Linux distribution. Then you can either create RPM or DEB packages, depending on your Linux distribution.

To build an RPM:

make rpm

To create a DEB package:

DEBFULLNAME="Mr. Buildmaster" DEBEMAIL="" make deb

Don't forget to insert your name and mail address. As a result you should find packages of the form check-mk-[edition]-[version].[deb|rpm] in your current directory.
