The present invention relates to a method for automatically analyzing a bottleneck in real time and an apparatus for performing the method. The method for automatically analyzing a bottleneck in real time may comprise the steps of: an application server receiving a bottleneck analysis component; and the application server installing the bottleneck analysis component, wherein the bottleneck analysis component may add a call code for a performance information collector to an application installed on the application server that is to be monitored, wherein the bottleneck analysis component may call the performance information collector according to execution of a service function of the application, requested by a client, to generate service performance information for analyzing a bottleneck phenomenon.
