Ever wonder what is stored in InnoDB buffer pool at the moment ?

It is not so hard actually – we made a short patch for MySQL 5.0 which show innodb buffer pool content

The binaries, RPMS (RedHat/Centos) and full source code also available to download

P.S. There is Jeremy Cole’s patch for InnoDB plugin MySQL 5.1, and main idea was taken from there.
