Hier here find some articles from outdated Checkmk versions. We have added them into the manual because there are no new articles for these topics yet – but we are working hard on it.

Please note: these articles had been written several years ago and things in Checkmk might behave differently now.

The majority of the legacy articles covers the development of own check plugins. Plugins that you develop based on these articles will probably work well, but use outdated APIs.
