I suggest placing the mysql-connector-java-5.0.8-bin.jar file from this in the plugins/lib folder of CrushFTP and giving it the name "mysql.jar".

Then go to Preferences, stats config and set the following items:

stats_db_url: jdbc:mysql://127.0.0.1:3306/crushftp_stats
stats_db_driver: com.mysql.jdbc.Driver
stats_db_user: root
stats_db_driver_file: plugins/lib/mysql.jar

Use MySQL Workbench and make a new DB with the name "crushftp_stats" (or adjust the URL above to reference the name you choose.) Below is the schema to put in it:

CREATE TABLE META_INFO (
  RID double NOT NULL,
  SESSION_RID double NOT NULL,
  TRANSFER_RID double NOT NULL,
  ITEM_KEY varchar(100) default NULL,
  ITEM_VALUE varchar(2000) default NULL,
  PRIMARY KEY  (RID)
);

CREATE TABLE SESSIONS (
  RID double NOT NULL,
  SESSION varchar(100) default NULL,
  SERVER_GROUP varchar(50) default NULL,
  USER_NAME varchar(100) default NULL,
  START_TIME datetime default NULL,
  END_TIME datetime default NULL,
  SUCCESS_LOGIN varchar(10) default NULL,
  IP varchar(50) default NULL,
  PRIMARY KEY  (RID)
);

CREATE TABLE TRANSFERS (
  RID double NOT NULL,
  SESSION_RID double NOT NULL,
  START_TIME datetime default NULL,
  DIRECTION varchar(8) default NULL,
  PATH varchar(255) default NULL,
  FILE_NAME varchar(2000) default NULL,
  URL varchar(2000) default NULL,
  SPEED int default NULL,
  TRANSFER_SIZE double default NULL,
  IGNORE_SIZE varchar(1) default NULL,
  PRIMARY KEY  (RID)
);

That is it. Now the statistics data should be going to the MySQL tables, and reports will automatically run against those tables too.
