Monit does not have this metric. It is implemented in the Monit Widget on OS X only (https://mmonit.com/monit/#widget). We do plan to back-port this later together with S.M.A.R.T. device status. In the meantime the best option is to do as suggested and use an external script. Monit can use Nagios scripts that return meaningful exist status, maybe one can be found?
