You posted this in the AppMon forum, but given that you tagged it with oneagent, you must be referencing the Dynatrace platform.
Linux Mint is essentially a Linux used by users. As all Linux distros, of course you can adapt to run server software, but nonetheless it is not displayed as a supported Linux distro:
When Dynatrace doesn't place it there, it's because "Dynatrace only tests and provides support " for those listed. Given that I use Linux Mint extensively, and that it is based on Debian, I would almost bet that you wouldn't have any problem with installing OneAgent in it. But then, you should check why you want to install it there, in the first place.
