Monocle is the next-generation profiler for Flash content running on desktop (Flash Player) and mobile devices (Adobe AIR). It allows developers to see things developers could not see in the past when profiling their Flash content.
Before Monocle, ActionScript 3 developers using Flash Builder profiler could see what was happening at the ActionScript level, but the rest was not visible. Things like network, rendering, etc. were not exposed and could not be profiled easily out of the box.
