Abstract:
1. A loopback device of mirroring a packet for a system visualization machine that analyzes packets flowing between servers in a multi-tier system so as to visualize transactions between the servers, comprising: a storage unit that stores a transmission source address, a transmission source port, and a transmission destination port; a reception unit that receives a packet including a transmission source address, a transmission source port, and a transmission destination port from one of target servers performing functions of two or more tiers; an exchange unit that exchanges the transmission source address and a transmission destination address of the received packet; a transmission unit that transmits the packet in which the addresses are exchanged to another of the target servers; and a mirroring processing unit that copies one of the received packet and sends the copy packet to the system visualization machine via an interface other than an interface connected with the servers.
