It would be nice to have an easy way to log several statistics and see their change over time. This could help solving performance issues or rebalance economy. Here are only a few possibilities of loggable characteristics:

ingame:

• AVG gp per character
• AVG exp per character
• monsters killed by type
• users per map

technichal:

• traffic in bytes between game-server and account-server
• logged on users

A preferred mechanism to store such an amount of values would be using the rrdtool (http://oss.oetiker.ch/rrdtool/index.en.html). Using the graphing mechanism allows us to create beautiful graphs about user growths or whatever. (http://oss.oetiker.ch/rrdtool/gallery/index.en.html) I wouldn't suggest storing those values in the database used by the account-server to separate real game data from the informational "overhead" data.

As logging those values and compiling rrdtool will cause some effort / overhead, logging should be an optional coponent of tmwserv using a compiler switch.
