If the plugin is enabled (normally this would only be enabled during active development), you will be notified by email and an entry placed in your log files at watchful.li.

Simply install this App using the Watchful remote installer (or the standard Joomla installer) on every site that uses the LESS Compiler and publish the app in the plugin manager. Be sure the site(s) on which you install this app has been added to your Watchful Dashboard and properly validated.
