Abstract

A network configuration diagram generate method executed by a computer, the method includes identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates; determining, for each change in a configuration of the predetermined system, a relationship of a communication distance between the plurality of virtual machines by using the location and the communication destination, the configuration indicating a relationship of the plurality of virtual machines; extracting a difference between the relationship of the communication distance before the configuration change and the relationship of the communication distance after the configuration change; and generating a network configuration diagram in which the extracted difference is indicated.

First claim

What is claimed is:

1. A network configuration diagram generate method executed by a computer, the method comprising:
identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates;
determining, for each change in a configuration of the predetermined system, each communication distance between virtual machines that have communication among the plurality of virtual machines by using the location and the communication destination, the configuration indicating whether communication between each of the plurality of virtual machines is present;
generating a first matrix that indicates each communication distance between the plurality of virtual machines corresponding to a row and a column as a symmetric matrix;
generating a second matrix that indicates each communication distance after change in the configuration when the location is changed; and
generating a network configuration diagram in which a difference between the first matrix and the second matrix is indicated.

2. The network configuration diagram generate method according to claim 1 , wherein
the network configuration diagram is indicated by a graph representing the plurality of virtual machines as nodes and communication relationships between the plurality of virtual machines as edges, and
the generating process includes:
associating the extracted difference with the edges, and
visualizing the associated edges in the network configuration diagram.

3. The network configuration diagram generate method according to claim 1 , wherein
the network configuration diagram indicates difference by representing addition or subtraction of amount of difference between the first matrix and the second matrix.

4. The non-transitory computer-readable storage medium according to claim 1 , wherein
the network configuration diagram indicates difference by representing addition or subtraction of amount of difference between the first matrix and the second matrix.

5. A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising:
identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates;
determining, for each change in a configuration of the predetermined system, each communication distance between virtual machines that have communication among the plurality of virtual machines by using the location and the communication destination, the configuration indicating-a whether communication between each of the plurality of virtual machines is present;
generating a first matrix that indicates each communication distance between the plurality of virtual machines corresponding to a row and a column as a symmetric matrix;
generating a second matrix that indicates each communication distance after change in the configuration when the location is changed; and
generating a network configuration diagram in which the extracted a difference between the first matrix and the second matrix is indicated.

6. The non-transitory computer-readable storage medium according to claim 5 , wherein
the network configuration diagram is indicated by a graph representing the plurality of virtual machines as nodes and communication relationships between the plurality of virtual machines as edges, and
the generating process includes:
associating the extracted difference with the edges, and
visualizing the associated edges in the network configuration diagram.
