      Description

      It's required to replace metric "InnoDB Buffer Pool Data" by "InnoDB Buffer Pool Size" in charts "MySQL Internal Memory Overview"

      PZ: "The point of this graph was to show what are the big memory users and compare it to the total memory -  ie we have key_buffer_size here for MyISAM tables - NOT comparable number of space which is used in key buffer
       
      Also note Innodb Buffer Pool is actually zero-filled on the start so it is really physically allocated even if not used."
