Thank you very much, @marcel.arentz, for your reply!
I see. But it’s still a pity, that I am not able to monitor my mssql instance running on Linux with checkmk. Didn’t you get this request from other people as well? (I didn’t find like lots of threads for this topic.) Are there just not enought instances running on Linux (yet) out there?
Is there a change that you would pick this up if more people would ask for it? Would it be an option (which would speed up the creation of such kind of a plugin) that we support you in creating a new plugin (no matter whether it would be a single plugin for Windows and Linux or a Linux-specific one)?
