Problem

Users and customers sometimes confuse the terms used to describe the Checkmk software and the Checkmk appliance.

Solution

There are two entirely different topics: The Checkmk appliance and the Checkmk software. Read on for the disambiguation.

Checkmk Appliance

The Checkmk appliance is an operating system in a can. It is a minimal platform to run the Checkmk software on, if your organization is not Linux-savvy.
The appliance has two flavors: A virtual template in OVA format and a physical server.

Both flavors contain - among others - the following features:

  • A preconfigured operating system, ready to support the Checkmk software
  • A console interface for first boot and basic configuration
  • A web interface for operating system level configuration, installing the Checkmk software, site management, and backup

Checkmk Software

The Checkmk software itself is the monitoring system you use all day. It can be installed on all major Linux distributions and the Checkmk appliance and run as a Docker container.
