Description:
When you view an Event, we show both the raw Expression as well as the Evaluated Expression, as in:

  Expression
  (%Uptime% < 10800) && ((%table_cache% - %Opened_tables%) <= THRESHOLD)

  Evaluated Expression
  (605177 < 10800) && ((256 - 0) <= 0)

However, when the expression includes a function call we don't show the result, as in:

  Expression
  ((%have_innodb% == "YES") && (locate('autoextend', %Innodb_data_file_path%) <= THRESHOLD))

  Evaluated Expression
  (("YES" == "YES") && (locate('autoextend', "ibdata1:10M:autoextend") <= 0))

This is from the "InnoDB Tablespace Cannot Automatically Expand" rule.

I believe this is a server-side thing.  If not, feel free to reassign.

How to repeat:
See above.

Suggested fix:
I think the correct thing to show is:

  Evaluated Expression
  (("YES" == "YES") && (13 <= 0))

Oldag has a prototype to fix this.  If easy we may want to discuss with Josh for 1.2.0
