I'm not sure if this is the correct forum, but am wondering if anyone knows if there is a plugin out there that tracks relevant server statistics and metrics for server owners, NOT plugin authors. Stuff like Day X retention rates, unique players, timeline statistics, graphing, timing between unique player server join and exit, etc. So, is there anything out there that does this?
I was looking for something a bit more geared towards server owners with statistics like Day 1/3/7 retention rates, average length of time before new players leave the server, etc. Something that is designed for server owners to improve their servers to bring in more players and keep them.
