Robotmk is the bridge technology between the testing tool Robot Framework and Checkmk.
Robotmk lets you run Robot Framework test cases periodically on test hosts to simulate arbitrary user actions on any interface: Web UIs, Desktop applications, REST APIs, databases, ...
It integrates these results into Checkmk services, giving you unprecedented visibility into the availability, performance, and functionality of your business applications - all this under a single monitoring interface: Checkmk.
It was developed during the pandemic 2020 by Simon Meggle as an "MKP" extension (Checkmk plugin package) and became quickly the most downloaded package on the Checkmk Exchange platform.
Since Checkmk 2.3, it is a natively integrated feature in Checkmk, now also called Synthetic Monitoring.
The recommended and actively maintained version is built into Checkmk under the name Synthetic Monitoring.
It can be used free of charge for up to 3 test services and up to 15 keywords.
Architecture:
- Checkmk Server: At least version 2.3 is required as a Checkmk server (Cloud or MSP version).
Robotmk is not compatible with the RAW edition of Checkmk. - Robotmk test hosts: Windows or Linux hosts on which the Robot Framework suites are to be executed by Robotmk.
- Checkmk Agent: supplemented in the Checkmk Agent Bakery with both the Robotmk Scheduler and the Agent Plugin, as well as the configuration file.
- Robotmk Scheduler: Spawned and supervised as a permanent subprocess of the Checkmk Agent ("extension").
Responsible for the parallel execution of Robot Framework plans in their individual intervals. - RCC: A command line tool which the scheduler uses to build individual Python environments for the individual suites.
This allows to run an arbitrary number of test suites with completely different dependencies (Python, Nodejs, ...) without interferences. - Robot Framework Suites: The scheduler executes these robot suites in the respective environments and pre-processes the results for the agent plugin.
- Robotmk Agent Plugin: similar to all other CMK agent plugins, this Plugin is called at the regular interval (1 minute).
It reads the last result of all Suite executions and uses it to build the Robotmk sections for the agent output.

The older MKP-based version is still available for Checkmk versions 2.3 and 2.4 and can be downloaded from the Checkmk Exchange.
