Display all deadlock logs in MySQL?


First of all, you need to enable innodb_print_all_deadlocks. Following is the syntax −

set global innodb_print_all_deadlocks=1;

After executing the above statement, let us execute the below syntax in order to display all deadlock logs −

show engine innodb status;

Let us implement the above syntax −

mysql> set global innodb_print_all_deadlocks=1;
Query OK, 0 rows affected (0.00 sec)

mysql> show engine innodb status;

This will produce the following output −
