question: private void logMin ( String type , String value , String arg , long amount ) { Key key = new Key ( type , value , arg + MINIMUM_INDICATOR ) ; synchronized ( counts ) { Long oldMin = counts . get ( key ) ; if ( oldMin == null ) { oldMin = amount ; } counts . put ( key , Math . min ( oldMin , amount ) ) ; } }
target:  Logs the minimum amount that was logged for (type, value, arg) under (type, value, arg_MIN).
