Hi!  
I would like to run pt-stalk on our mysql (5.1 and 5.5) servers but have seen in our test environment that it writes up towards a gigabyte of mutex data when it is triggered. I’m worried that this will worsen the situation if the reason for the trigger is heavy disk I/O. Is it possible to disable the logging of the “-mutex-status” files in pt-stalk?

Best regards,  
Patrik
