A customer recently was asking why our FromDual Performance Monitor for MariaDB and MySQL (fpmmm) is not working on Windows...? The answer is short: It was developed on Linux and never tested on Windows...
But I was wondering how much effort it would take to make it work on Windows as well.
I was quite surprised how fast it was to make the basic functionality working on Windows. It took me less than one hour to install, configure and patch FPMMM.
