<p>PROBLEM TO BE SOLVED: To clarify whether or not communication between VMs capable of being executed over a plurality of host machines is communication limited within the same host machine.SOLUTION: A communication analyzer comprises: definition storage means for storing a switch number, a host number, and a communication network connection terminal number of a virtual switch in a communication network in which a plurality of host devices including a virtual machine and virtual switch are connected; history storage means for storing a record including a switch number, an input terminal number, an output terminal number, a communication address, and communication time received from a relayed virtual switch for each communication between virtual hosts; and acquisition means which extracts first and second records and detects communication between host devices obtained using switch numbers of the first and second records, where the first record is a record whose output terminal number is a communication network connection terminal number, and the second record is a record whose input terminal number is a communication network connection terminal number and whose communication address and communication time agree with those of the first record.</p> |
