Virtual network monitoring system, virtual network monitoring apparatus, virtual network monitoring method, and non-transitory computer-readable recording medium

A virtual network monitoring system comprising:

• an acquisition unit configured to acquire first network information, the first network information being network information possessed by a virtual machine control unit functioning as an orchestrator, and second network information, the second network information being network information possessed by a virtual machine generated by the virtual machine control unit among network information on a virtual network to which the virtual machine is connected;
• and
• a generation unit configured to generate a traffic filter indicating a filter for traffic flowing through the virtual network on the basis of the first network information and the second network information.

A virtual network monitoring method comprising:

• an acquisition step of acquiring, by one or a plurality of information processing apparatuses, first network information, the first network information being network information possessed by a virtual machine control unit functioning as an orchestrator, and second network information, the second network information being network information possessed by a virtual machine generated by the virtual machine control unit among network information on a virtual network to which the virtual machine is connected;
• and
• a generation step of generating, by the one or plurality of information processing apparatuses, a traffic filter indicating a filter for traffic flowing through the virtual network on the basis of the first network information and the second network information.
