Catalog of Check Plug-ins
All plug-ins listed here are actively maintained by the Checkmk team. Further free plug-ins from users, partners or third parties are available at the Checkmk Exchange.
If you need a plug-in that is not listed here, please contact us via the support portal (requires a support contract as well as free development capacity). Alternatively many of our partners can help you as well.
Notes:
- Almost every week we develop new check plug-ins. You might have to update Checkmk in order to be able to use them. Some of these plug-ins are only available in the development branch of Checkmk.
- Some plug-ins are listed in more than one category
