Claim:
1. A capture point determination method in a system including a first physical machine including a first processor and a plurality of second physical machines each including a second processor capable of executing a hypervisor that operates virtual machines and a virtual switch, the method comprising: obtaining, by the first processor, a plurality of candidates for a combination of ports of each virtual switch through which packets transmitted and received between the virtual machines are collected, and calculating, for each virtual switch, an increment of a usage of the second processor in accordance with a number of packets to be collected, by using a usage of the second processor by the virtual switch and a number of packets passing through each port when mirroring is executed and when mirroring is not executed, respectively; calculating, by the first processor, for each of the second physical machines, a usage of the second processor by the hypervisor when mirroring is executed, by using a calculated increment of a usage of the second processor by the virtual switch and a usage of the second processor by the hypervisor when mirroring is not executed, for each of the plurality of candidates; and determining, by the first processor, a combination of ports used for collection of packets, from among the plurality of candidates in accordance with a deviation of the usage of the second processor by each hypervisor calculated for each candidate.
