show engine innodb status not showing most recent deadlock

[Stephen McCants]

I'm seeing deadlocks from time to time in my application logs and I'd like to track them down. Most posts on the internet say to run:

show engine innodb status;

This shows the "LASTEST DETECTED DEADLOCK". but it is from August of last year even though I've had 3 other deadlocks in the last two days.

Is there something I need to turn on?
Is there a way to track this down some other way, such as the performance_schema tables?

I'm running (according to "select VERSION();"):

MySQL 5.6.41-log

Thanks in advance.

This is run under Red Hat Enterprise Linux Server release 7.5 (Maipo).
