Description

  The present invention relates to a display system, a display method, a display program, and a virtual system, and in particular, a display system and display capable of identifying bottleneck locations and affected locations by displaying logical configurations and physical configurations in the field of network functions virtualization (NFV) operation management. Method, display program and virtual system

  Various technologies related to virtualization systems have been devised. For example, Patent Document 1 describes a virtualization system, a resource management server, a resource management method, and a resource management program for changing resource allocation so as to improve performance. Patent Document 2 also includes a network management device, a connection request device, a network system, and a method of constructing a virtualized network, which virtualizes a network so that physical NICs (Network Interface Cards) do not compete or resources are exhausted. Have been described.

  There is a technology called network function virtualization (NFV) that provides a network environment in which the function of a communication device that controls a network is executed by application software that operates on a virtualized OS (Operating System) of a general-purpose server.

  In the NFV field, operation management considering the entire system is not performed by targeting a virtual OS that configures a virtual network (hereinafter, also referred to as a virtual NW) and Server, Storage, and the like in the physical layer.

  The reason is that only the network path and the bottleneck of the virtualized server are monitored in the operation management of the NFV, and there is no way to clearly express the bottleneck of the whole system. Therefore, the user of the system to which the NFV is applied does not know the cause of the bottleneck, and can not sufficiently cope with the bottleneck of the entire system. That is, the user can not sufficiently solve the bottleneck of the entire system.

  FIG. 13 is an explanatory view showing a display example of the configuration of a virtual NW in which a bottleneck exists. The double frame shown in FIG. 13 means, for example, a frame of a screen on which the configuration of the virtual NW is displayed. The same applies to the other figures below.

  FireWall shown in FIG. 13 is a virtual OS 40, Router and NAT (Network Address Translation) are virtual OS 41, and DPI (Deep Packet Inspection) is virtual OS 42. Each component is connected by Logical Link. Further, the End Point on the left side is connected to the End Point on the right side via the virtual NW shown in FIG.

  The double frame block shown in FIG. 13 means a bottleneck point. The same applies to the other figures below. As shown in FIG. 13, a bottleneck of the virtual NW exists in the Router. It is assumed that the user adds a resource to the virtual OS 41 based on the display content shown in FIG.

  A display example of the configuration of the virtual NW after the user adds the resource to the virtual OS 41 is shown in FIG. FIG. 14 is an explanatory view showing another display example of the configuration of the virtual NW in which the bottleneck exists. As shown in FIG. 14, the virtual OS 41, Server, and Storage are connected by Physical Link.

  A double-framed block in which hatching is shown between the frame shown in FIG. 14 means a bottleneck countermeasure point. The bottleneck coping point is a point directly or indirectly related to coping with the bottleneck that has occurred. The same applies to the other figures below.

  As shown in FIG. 14, since the resource is added to the virtual OS 41, the bottleneck in the Router is eliminated. However, there is a bottleneck in Storage. That is, FIG. 14 shows that the cause of occurrence of the bottleneck in the Router relates to Storage. It can be understood that the response method for adding resources to the virtual OS 41 is not an appropriate response method because the cause of occurrence of the bottleneck relates to Storage.

  As shown in FIG. 13, the normal operation method of the NFV is a method of monitoring the virtual NW and the virtual OS, and adding a resource to the component of the virtual NW and the virtual OS when the bottleneck occurs.

  In normal NFV service chain management techniques, only the relationship between the physical server and the virtual server running on the physical server is used. That is, the relationship between the storage and the firewall that the virtual server further uses and the virtual server is not used.

  However, in the method of displaying only the virtual NW configuration as shown in FIGS. 13 to 14, the cause of the occurrence of the bottleneck may not be displayed. If the cause of the bottleneck is not displayed, the user can not cope with the cause. Simply adding resources to the virtual OS where a bottleneck exists without dealing with the cause of the occurrence may not solve other bottlenecks that exist in the system.

  In the patent document 3, in a system in which a plurality of virtual computers share physical resources, a performance monitoring system for determining a bottleneck after considering a physical resource allocation policy, the influence on software, a bottleneck determination method, and a management computer Is described. However, in the technology described in Patent Document 3, it is assumed that only a bottleneck in a system in which a plurality of virtual computers share physical resources is determined, and it is assumed that a bottleneck in the NFV field is determined. Not.

JP, 2013-206101, A JP, 2014-131226, A JP, 2010-250689, A Unexamined-Japanese-Patent No. 2004-222105

  Patent Document 4 describes a virtual network operation status display device that manages the relationship between a virtual network and a network in a lower layer of the virtual network, and displays a network operation configuration. The virtual network operation status display device displays the network operation configuration so that the user can grasp the network configuration of the upper layer and the network configuration of the lower layer at a glance. Further, the virtual network operation status display device displays the network operation configuration so that the user can easily determine the range affected by the failure when the failure occurs.

  If the virtual network operation status display device described in Patent Document 4 is used, the virtual NW configuration and the physical NW configuration are displayed together, so the above problem is solved. That is, the user can determine the location to be coped with and the corresponding method from the displayed content.

  However, when taking measures to eliminate the bottleneck based on the display content, the following problems may occur. FIG. 15 is an explanatory view showing a display example of the configuration of the virtual NW and the configuration of the physical NW where a bottleneck exists. The Router shown in FIG. 15 operates on the virtual OS 41. The virtual OS 41, the server 51, the storage 60, and the storage 61 are connected by physical links.

  As shown in FIG. 15, bottlenecks exist in Router and Storage 61. It is assumed that the user moves the data for Router stored in Storage 61 to Storage 60 based on the display content shown in FIG.

  A display example of the configuration of the virtual NW and the configuration of the physical NW after the user moves data to the Storage 60 is shown in FIG. FIG. 16 is an explanatory view showing another display example of the configuration of the virtual NW and the configuration of the physical NW in which the bottleneck exists. The FireWall shown in FIG. 16 is connected to the Router by Logical Link and operates on the virtual OS 40. The virtual OS 40, Server 50, and Storage 60 are connected by Physical Link.

  As shown in FIG. 16, each bottleneck in the Router and Storage 61 is eliminated. However, a new bottleneck exists in FireWall. That is, it can be understood that the coping method of moving the data stored in the Storage 61 to the Storage 60 is the cause of causing a new bottleneck in FireWall.

  As described above, there is an operation method of monitoring the virtual OS, Server, and Storage configuring the virtual NW using the virtual NW configuration and the physical NW configuration displayed together, and dealing with the occurrence of a bottleneck. However, there is a problem that the implementation of the coping method may cause a new bottleneck at another place. Therefore, there is a need for a system that can present a user with a countermeasure that has been implemented but does not affect other places.

  Further, in the virtual network operation status display device described in Patent Document 4, it is not assumed to display a coping method for failure. There is a need for a system that displays a bottleneck location and a coping method together with the virtual NW configuration and the physical NW configuration so that the user can easily execute the presented coping method.

  Therefore, the present invention solves the above-mentioned problems, and a display system for displaying together a virtual NW configuration and a physical NW configuration in which a bottleneck location is shown, and a best bottleneck response method that does not affect other locations, It aims at providing a display method, a display program, and a virtual system.

Embodiment 1
[Description of configuration]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a first embodiment of a display system according to the present invention. A display system 100 illustrated in FIG. 1 includes an NW measurement unit 101, HW measurement units 111 to 114, a bottleneck determination unit 121, and a display unit 131. The number of HW measurement units included in the display system 100 may be other than four.

  Further, in the present embodiment, a system to be displayed by the display system 100 is the virtual system 200 shown in FIG. A virtual NW and a virtual OS exist in the virtual layer of the virtual system 200. Further, in the physical layer of the virtual system 200, Server and Storage exist.

  The virtual NW is configured by FireWall, Router, NAT, and DPI. Note that FireWall, Router, NAT, and DPI shown in FIG. 1 are network applications (hereinafter, NW applications) having a function of a communication device that controls a network.

  As shown in FIG. 1, FireWall operates on the virtual OS 10, Router and NAT operate on the virtual OS 11, and DPI operates on the virtual OS 12. Each component is connected by Logical Link.

  Further, as shown in FIG. 1, the virtual OS 10 and Server 20, the virtual OS 11 and Server 21 and the virtual OS 12 and Server 22 are connected by Physical Link, respectively. The physical NWs in the physical layer include servers 20 to 22 and storages 30 to 32. The left end point is connected to the right end point via the virtual system 200.

  The NW measurement unit 101 has a function of measuring the performance value in the virtual NW. Based on the measured performance value, the NW measurement unit 101 detects a bottleneck present in the virtual NW. As shown in FIG. 1, the NW measurement unit 101 detects a bottleneck that occurs in FireWall, Router, NAT, and DPI. Hereinafter, a place where a bottleneck exists is referred to as a bottleneck place.

  For example, the NW measurement unit 101 detects a bottleneck by detecting a reduction in processing amount, an increase in processing delay, and a resource shortage required for processing. In addition, the NW measurement unit 101 may set a threshold of each performance value to be measured, and may detect a bottleneck when the performance value exceeds the threshold. In addition, the NW measurement unit 101 may detect a bottleneck after combining various methods for detecting the bottleneck.

  In addition to measuring performance values from virtual devices and detecting bottlenecks, the NW measurement unit 101 may also detect bottlenecks by receiving notification or alerts from bottleneck locations. Good. When the NW measurement unit 101 receives a notification from a bottleneck location, the detection of the bottleneck may be performed by the virtual device itself in which the bottleneck exists, or may be performed by a management system that manages the virtual device.

  The HW measurement units 111 to 114 have a function of measuring performance values from the NW application such as FireWall and Router to Storage. The HW measuring units 111 to 114 detect a bottleneck based on the measured performance values. Note that, similarly to the NW measurement unit 101, the HW measurement units 111 to 114 may also detect a bottleneck by receiving a notification or an alert.

  As shown in FIG. 1, the HW measurement unit 111 detects a bottleneck that occurs in FireWall, virtual OS 10, Server 20, and Storage 30. In addition, the HW measurement unit 112 detects a bottleneck that occurs in the Router, the virtual OS 11, the Server 21, and the Storage 31. The HW measurement unit 114 also detects a bottleneck occurring in the DPI, the virtual OS 12, the server 22, and the storage 32. In addition, the bottleneck which arises in NAT is detected by the HW measurement part 113 (not shown).

  The bottleneck determination unit 121 has a function of determining the influence of a bottleneck or the like based on the measurement values measured by the NW measurement unit 101 and the HW measurement units 111 to 114.

  In the present embodiment, the bottleneck location includes a location where a failure has occurred in addition to the location where the performance has deteriorated.

  The display unit 131 has a function of displaying bottleneck locations detected by the NW measurement unit 101 and the HW measurement units 111 to 114. For example, the display unit 131 displays a configuration diagram of the virtual system 200 in which a bottleneck location is indicated. The block diagram of the virtual system 200 to be displayed shows the configuration of the virtual network in the virtual layer and the configuration of the physical network in the physical layer. Also, the configuration diagram of the virtual system 200 shows the correspondence between the virtual layer and the physical layer.

  Note that the display system 100 of the present embodiment is realized by, for example, a CPU (Central Processing Unit) that executes processing in accordance with a program stored in a storage medium. That is, the NW measurement unit 101, the HW measurement units 111 to 114, the bottleneck determination unit 121, and the display unit 131 are realized by, for example, a CPU that executes processing according to program control.

  Also, each unit in the display system 100 may be realized by a hardware circuit.

[Description of operation]
Hereinafter, the operation of the display system 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing an operation of display processing by the display system 100 in the first embodiment.

  For example, the NW measurement unit 101 measures the processing time of each NW application that configures the virtual NW. By measuring the processing time, the NW measurement unit 101 detects a bottleneck location of the virtual NW. After detection, the NW measurement unit 101 transmits measurement data to the bottleneck determination unit 121 (step S101). As shown in FIG. 1, in the present embodiment, the NW measurement unit 101 detects a router as a bottleneck location.

  Next, the HW measurement units 111 to 114, for example, measure the processing time in each component from the NW application to be measured to the storage. By measuring the processing time, the HW measuring units 111 to 114 detect bottleneck locations. After the detection, the HW measurement units 111 to 114 transmit measurement data to the bottleneck determination unit 121 (step S102). The display system 100 may perform the process in step S101 and the process in step S102 in parallel.

  In the present embodiment, the HW measurement unit 111 measures the processing time in each of the FireWall, the virtual OS 10, the Server 20, and the Storage 30. The HW measurement unit 112 also measures the processing time in the router, the virtual OS 11, the server 21 and the storage 31, respectively. The HW measurement unit 114 also measures the processing time in the DPI, the virtual OS 12, the server 22, and the storage 32, respectively. As shown in FIG. 1, in the present embodiment, the HW measurement unit 112 detects Storage 31 as a bottleneck location.

  Next, the bottleneck determination unit 121 detects the cause of the bottleneck in the entire virtual system 200. After the detection, the display unit 131 displays a configuration diagram of the virtual system 200 in which the bottleneck locations detected by the NW measurement unit 101 and the HW measurement units 111 to 114 are indicated (step S103).

  The display unit 131 displays, for example, a configuration diagram of the virtual system 200 on a screen provided in the display system 100. The display unit 131 may also display the configuration diagram of the virtual system 200 on the screen of a user terminal communicably connected to the display system 100.

  An example of a configuration diagram of the virtual system 200 displayed by the display unit 131 in the present embodiment is shown in FIG. FIG. 3 is an explanatory view showing a display example of the virtual system 200 by the display unit 131 in the first embodiment.

  From the block diagram of the virtual system 200 shown in FIG. 3, it can be understood that the processing of the Router detected as a bottleneck location of the virtual NW depends on the Storage 31. Since Storage 31 is also detected as a bottleneck location, it is revealed that Storage 31 is the source location of the bottleneck that exists in the entire virtual system 200. The bottleneck determination unit 121 identifies the cause of the bottleneck present in the entire virtual system 200 based on the measurement information and the like of the NW measurement unit 101 and the HW measurement units 111 to 114.

  Next, the bottleneck determination unit 121 examines candidates for a method of coping with the identified cause of the bottleneck. In addition, the bottleneck determination unit 121 examines the influence when each candidate for the considered countermeasure is implemented. The measures to be considered are, for example, addition of resources, change of resource allocation, and reduction of other resources.

  The bottleneck determination unit 121 determines an action that can be taken based on the values measured by the NW measurement unit 101 and the HW measurement units 111 to 114, the system configuration, the setting values of the respective components, and the like. In addition to the setting contents of the system configuration, the bottleneck determination unit 121 may determine the coping method in consideration of the coping method for the cause of the bottleneck that has occurred in the past. The bottleneck determination unit 121 determines a plurality of candidates for how to deal with the identified cause of the bottleneck.

  Based on the values measured by the NW measurement unit 101 and the HW measurement units 111 to 114, the bottleneck determination unit 121 determines whether or not there is no influence due to the implementation of each of the determined measures. The impact of implementing the coping method is, for example, the occurrence of new bottlenecks elsewhere.

  When there is a candidate for a coping method that is not affected by implementation, the bottleneck determination unit 121 causes the display unit 131 to have a coping method that is not affected and that the implementation is not affected by the configuration diagram of the virtual system 200. Send an indication. In addition, when there is no candidate of the coping method which does not have influence by implementing, the bottleneck determination part 121 may transmit the instruction | indication which shows the optimal coping method in a candidate.

  The display unit 131 displays a configuration diagram of the coping method transmitted from the bottleneck determination unit 121 and the virtual system 200 in which it is shown that there is no influence by the implementation (step S104). Note that the display unit 131 may indicate a plurality of candidates for the handling method determined by the bottleneck determination unit 121.

  When the bottleneck determination unit 121 determines that there is a candidate capable of reducing resources, the display unit 131 displays a configuration diagram of the virtual system 200 in which the candidates capable of reducing resources are indicated (step S105). The display system 100 may perform the process in step S105 before the process in step S104.

  By clarifying the cause of the bottleneck, the bottleneck judging unit 121 can determine the coping method as shown in FIGS. 4 to 6 in consideration of the entire system.

  FIG. 4 is an explanatory view showing another display example of the virtual system 200 by the display unit 131 in the first embodiment. FIG. 4 shows a configuration diagram displayed by the display unit 131 when it is considered to simply add a resource to the Storage 31 as a coping method. FIG. 4 shows adding a resource to Storage 31 as a coping method. It has also been shown that if the suggested measures are implemented, the bottleneck is eliminated without affecting other parts.

  When a bottleneck as shown in FIG. 3 occurs, the bottleneck determination unit 121 can determine an appropriate countermeasure for the cause as shown in FIG. 4 by clarifying the cause of the bottleneck. According to the countermeasure shown in FIG. 4, the user adds resources to the cause of the bottleneck. By adding resources, bottlenecks in the entire system are eliminated.

  FIG. 5 is an explanatory view showing another display example of the virtual system 200 by the display unit 131 in the first embodiment. FIG. 5 shows a configuration diagram displayed by the display unit 131 when it is considered to change resource allocation as a coping method.

  FIG. 5 shows that the server on which the virtual OS 11 is operated is changed from Server 21 to Server 22 as a coping method. The change of the server on which the virtual OS operates is performed, for example, by migration processing using VMotion of VMware (trademark registration). In addition, it is also shown that, when the presented countermeasure is implemented, the bottleneck is eliminated without affecting other places, particularly the server 22.

  As described above, the bottleneck determination unit 121 can understand in advance the influence of the change in resource allocation on other places. By grasping the influence in advance, the bottleneck determination unit 121 can present a coping method in which a new bottleneck does not occur.

  According to the coping method shown in FIG. 5, the user can implement the change of the resource allocation in which the new bottleneck does not occur. By changing the resource allocation, the bottleneck of the whole system is eliminated.

  FIG. 6 is an explanatory view showing another display example of the virtual system 200 by the display unit 131 in the first embodiment. FIG. 6 shows a configuration diagram displayed by the display unit 131 when it is considered to change resource allocation as a coping method.

  For example, it is assumed that the bottleneck determination unit 121 determines that the Storage at the bottleneck location can only process up to three times the processing amount of the current processing amount. Next, the bottleneck determination unit 121 determines that the amount of resources allocated to other locations can be reduced to a processable amount that can be three times the processing amount of the current processing amount. After examining the reduction amount, the bottleneck determination unit 121 outputs the location to which the reducible resource is allocated and the reducible resource value.

  Specifically, if 33% of the total processing capacity of the Storage at the bottleneck location is used, the Storage at the bottleneck location is at most up to three times the processing volume of the current processing volume. It can not be processed. That is, even if the performance of the entire system is improved, it is considered that the amount of processing in the other components will not be tripled or more.

  It is assumed that ten CPUs are allocated as resources to another virtual OS, and the current CPU utilization of the other virtual OS is 20%. If the current amount of processing is tripled, the CPU usage rate in 10 CPUs will be 60%. Therefore, even if the current processing amount is tripled, the CPU utilization of other virtual OSs does not exceed 100% if six CPUs are allocated, so up to four CPUs from other virtual OSs It is judged that it can reduce.

  FIG. 6 shows that the resources allocated to Storage 30 and Storage 32 are maximally reduced and the reduced resources are allocated to Storage 31 as a coping method. Further, it is shown that the resources allocated to the virtual OS 10 and the virtual OS 12 are maximally reduced, and the reduced resources are allocated to the virtual OS 11. In addition, it is also shown that, when the presented countermeasure is implemented, the bottleneck is eliminated without affecting the other parts, particularly the virtual OS 10, the virtual OS 12, the Storage 30, and the Storage 32.

  As shown in FIG. 6, the resources allocated to other places are reduced as much as possible in accordance with the performance value of the cause of the bottleneck, whereby the resource allocation in the entire system is made more efficient.

  After the display unit 131 displays the coping method transmitted from the bottleneck determination unit 121 and the configuration diagram of the virtual system 200 in which there is no influence by the implementation, the display system 100 ends the processing.

  In addition, the bottleneck determination unit 121 may arrange values in a time series by analyzing values measured by the NW measurement unit 101 and the HW measurement units 111 to 114, and predict a portion where a bottleneck may occur in the future. . In addition, the bottleneck determination unit 121 may transmit information on a portion where a bottleneck may occur to the display unit 131, and the information transmitted by the display unit 131 may also be shown in the system configuration diagram.

  The display unit of the display system in the present embodiment displays in parallel the logical configuration including the virtual network route and the configuration of the virtualized server and the physical configuration including the network route and the configuration of the server. As a result of the display, the user can understand the correspondence between the bottleneck present in the logical configuration and the bottleneck present in the physical configuration, and can identify the cause of the bottleneck present in the entire system. In addition, by knowing the correspondence relationship, the user can also identify other places that the cause of the bottleneck affects.

  By displaying the logical configuration and the physical configuration of the entire system in parallel, even if a bottleneck as shown in FIG. 3 occurs, the user can use the virtual OS, Server, Storage, etc. that form the virtual NW. It is possible to clearly determine which part of what should be dealt with. The reason is that since the logical configuration and the physical configuration are displayed in parallel, the cause of the bottleneck is clarified, and the user can respond to the cause.

  In addition, the display unit of the display system in the present embodiment can also present an appropriate method for coping with the cause of the bottleneck. As a coping method, for example, appropriate resource augmentation for the cause of the bottleneck is presented. In addition, a method is presented to reduce the resources allocated to places other than the cause of the bottleneck as much as possible and to allocate the reduced resources to the cause.

  In addition to the addition of resources, as a countermeasure presented, in the case of storage in the physical layer, for example, data stored in a partition which is a bottleneck location is processed in a memory having higher I / O performance. Data relocation or repartitioning. In addition, the priority of the processing request received from the virtual OS which is the bottleneck location is made relatively high, or the priority of the processing request received from the virtual OS other than the virtual OS which is the bottleneck location is made relatively low. , Storage configuration changes.

  In addition, as a coping method presented elsewhere, among virtual OSs that send requests to storage that is a bottleneck location, to lower the priority or frequency of requests from virtual OSs other than the virtual OS that is a bottleneck location. , Virtual OS or virtual OS host server configuration change.

  In addition, the bottleneck determination unit of the display system in the present embodiment makes clear the influence that the change of the setting of the cause of the bottleneck has on other places. The bottleneck determination unit presents the user with a coping method that does not affect the other places, after determining the influence of the plurality of coping methods that can be implemented on the other parts. Therefore, the user of the display system can safely perform the recovery work according to the presented countermeasure.

  In the present embodiment, it is assumed that a virtual system including two virtual NWs is targeted. FIG. 7 is a block diagram showing a configuration example of the virtual system 300. As shown in FIG. As shown in FIG. 7, the virtual system 300 includes a first virtual NW and a second virtual NW.

  A virtual NW and a virtual OS exist in the virtual layer of the virtual system 300. Further, in the physical layer of the virtual system 300, Server and Storage exist. The physical NWs in the physical layer include servers 23 to 25 and storages 33 to 35.

  The difference between the display unit 131 of the present embodiment and the first embodiment is that it also displays other virtual NW locations affected by the cause of the bottleneck.

  As shown in FIG. 7, the virtual system 300 is a system of an environment including a plurality of virtual NWs. Also, as shown in FIG. 7, bottlenecks exist in Router and Server 24. In consideration of the system configuration shown in FIG. 7, it can be understood that Server 24 is the cause of the bottleneck.

  Referring to FIG. 7, the router of the second virtual NW uses Server 24 which is the cause of the bottleneck of the first virtual NW. That is, when a higher load is applied to the router of the first virtual NW than in the surrounding components, a high load is also applied to the server 24. Then, when a high load is applied to the server 24, it can be understood that the router of the second virtual NW may be affected.

  As described above, when there is a possibility that a bottleneck such as a high load may occur in the Router of the first virtual NW, it is understood that the second virtual NW is also required to cope. In the present embodiment, the display unit 131 displays the places of other virtual NWs for which correspondence is required. FIG. 8 is an explanatory view showing a display example of the virtual system 300 by the display unit 131 in the second embodiment.

  As shown in FIG. 8, the display unit 131 indicates that the router of the second virtual NW may be affected in addition to the presence of the bottleneck in the router and the server 24 of the first virtual NW. The black frame block shown in FIG. 8 means a place that may be affected by the cause of the bottleneck of another virtual NW. The same applies to the other figures below.

  According to the display unit of the display system of the present embodiment, other virtual NWs that are affected by the cause of the bottleneck in the virtual NW are also clarified. Therefore, the user can also carry out correspondence to other virtual NW locations in advance.

In addition, the places where the performance has deteriorated include places where a failure has occurred.

  Specifically, the determination unit 83 specifies that the cause of the deterioration of each performance of the related first performance reduction location and the second performance reduction location is the second performance reduction location.

  The determination unit 83 takes into consideration the state of each component of the virtual system, and examines the influence given to each other place when each candidate of the examined response method is implemented. After examination, the determination unit 83 determines a countermeasure that does not degrade the performance without affecting other parts even if it is implemented among the candidates for the examined countermeasure.

  In addition, the display unit 84 may also display that the countermeasure method does not generate a new performance-degraded part.
