Provided herein is a real-time QoS monitoring apparatus, including an application registration unit configured to register at least one monitoring target application program for QoS measurement; a function explorer unit configured to detect user-defined functions in application code of the at least one monitoring target application program; a loop-statement explorer unit configured to detect loop-statements in the application code; a user-defined location explorer unit configured to detect user-defined locations in the application code; and a heartbeat generator configured to generate a plurality of heartbeat calls to correspond to the functions detected by the function finder, the loop-statements detected by the loop finder, and the user-defined locations detected by the user-defined location finder. Accordingly, there are provided a real-time QoS monitoring apparatus and method, which may measure QoS in real time without additionally modifying the application program.
