Description
If a deadlock happens (SHOW ENGINE INNODB STATUS) the server status variable innodb_deadlocks will be increased.
If a foreign key error happens (SHOW ENGINE INNODB STATUS) there is NO server status variable exists indicating this even.
So it would be good to have a server status variable like innodb_foreign_key_errors which indicates the amount of FK errors we had since last database start.
