Description:
Currently, we cannot set monitor counter from my.cnf does not activate the counters. This bug is filed to support such:

We do not process the variable's corresponding global variable innobase_enable_monitor_counter during server startup in innobase_init(). So specify this in the my.cnf will have no effect on the variable.

The reason has been that we think this is a variable that would always be off by default, and user uses "set global innodb_enable(/disable/reset/reset_all)_monitor_counter" to turn on/off it.  So all of these system variables can be set during run time at command line.

However, said that, innodb_enable_monitor_counter might be a bit special, as in your case, users might want to turn it (a group) on by default. I can add this support.

Workaround is to use SET after server startup.
