How to get player statistics from server?

[hsnzam]

Hi,
I am using Rcon to get simple data (for example players score) of my server every 5 min and save it for statistical analysis, I hope I can get something interesting out of it. But these data are very little, so I will be happy if someone knows:

1. How to fetch simple data from a server I don't own?
2. How to fetch more data (for example total XP, accolades, challenges done) of players how play on my server?

Thanks
