Enter your own Checkmk ideas or vote for existing ones
In order to continually improve Checkmk, we're looking for your ideas. They provide valuable input to our roadmap discussions and allow us to contact you directly for more in-depth discussions or during development. A few tips:
- Concisely describing the problem rather than the solution will help other users understand and relate to your idea.
- An idea should be easy to understand. This will increase your chances of getting votes.
- Be as specific as possible. Knowing exactly what to expect when voting on an idea makes it a much better experience for all of us when it is adapted later in Checkmk.
Further information can be found in this guide. If you have any questions, please send an email to ideas@checkmk.com.
