Claim:
1. A method for monitoring transactions by analyzing packets in a packet processing system capable of processing packets transmitted from at least one client device, comprising steps of: (a) an application performance monitoring (APM) device classifying or supporting to classify at least one packet, if being acquired in the packet processing system through port mirroring, based on at least either of a port number and an IP address of the client device; (b) the APM device identifying and supporting to identify at least one pair of (i) at least one packet transmitted from at least one specific device among a plurality of devices, including the client device and at least one processing device in the packet processing system and (ii) at least one packet transmitted to the specific device in response to the at least one packet transmitted from the specific device by considering at least one packet under an identical classification; and (c) the APM device acquiring information on the transactions by using information on the identified pair of the packets; wherein the packet processing system includes: a web server for receiving and processing a request of the client device, a WAS for receiving and processing the request of the web server, and a database server for receiving and processing a query request of the WAS and returning a result of the query request, wherein the port mirroring is processed by switches connected respectively to the web server, the WAS, and the database server, and wherein the port mirroring is processed when the web server, the WAS, and the database server forward respective packets to particular ports of the switches, respectively.
