innotop is a MySQL and InnoDB transaction/status monitor, like 'top' for
MySQL.  It displays queries, InnoDB transactions, lock waits, deadlocks,
foreign key errors, open tables, replication status, buffer information,
row operations, logs, I/O operations, load graph, and more.  You can
monitor many servers at once with innotop.
