1. Introduction

This document lists the platforms and integrations supported by Checkmk 2.2.0. Except for very specific reasons (e.g. security), these platforms, including all patch versions will remain supported through active maintenance during the Checkmk 2.2.0 product lifecycle.

2. Server OS

Checkmk can be installed on the following Linux server OS distributions and versions running on x86_64 hardware. Entries might contain the following additions:

  • Deprecated: LTS/LTSS versions marked in this way are still supported for the entire life cycle of version 2.2.0. Support will be ceased afterwards. For Ubuntu STS versions, supplying Checkmk 2.2.0 packages ends shortly after Ubuntu stops supporting them with updates.

  • Once released: Support for these versions is planned. Checkmk 2.2.0 packages will be made available shortly after the release of the new distribution version.

We will additionally evaluate any new versions of these distributions as a part of our ongoing support process. These will be covered in the update matrix.

Important: Starting with Checkmk 2.3.0 Ubuntu STS versions will not be supported anymore.
