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 that can identify a bottleneck part and an affected part by displaying a logical configuration and a physical configuration in the operation management field of NFV (Network Functions Virtualization). The present invention relates to a method, a display program, and a virtual system.

  Various technologies related to the virtualization system have been devised. For example, Patent Literature 1 describes a virtualization system, a resource management server, a resource management method, and a resource management program that change resource allocation so that performance is improved. Patent Document 2 discloses a network management apparatus, a connection request apparatus, a network system, and a virtual network construction method for virtualizing a network so that physical NICs (Network Interface Cards) do not compete and resources are not exhausted. Have been described.

  There is a technology called NFV (Network Function Virtualization) 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 that considers the entire system is not performed by targeting a virtual OS that constitutes a virtual network (hereinafter also referred to as a virtual NW) and a server, storage, etc. in the physical layer.

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

  FIG. 13 is an explanatory diagram illustrating a display example of the configuration of a virtual NW in which a bottleneck exists. The double frame illustrated in FIG. 13 means, for example, a frame of a screen on which the virtual NW configuration is displayed. The same applies to the other drawings.

  The FireWall shown in FIG. 13 operates on a virtual OS 40, Router and NAT (Network Address Translation) operate on a virtual OS 41, and DPI (Deep Packet Inspection) operates on a virtual OS 42. Each component is connected by Logical Link. Further, the left end point is connected to the right end point via the virtual network shown in FIG.

  The double-frame block shown in FIG. 13 means a bottleneck location. The same applies to the other drawings. As shown in FIG. 13, the 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 a resource to the virtual OS 41 is shown in FIG. FIG. 14 is an explanatory diagram illustrating another display example of the configuration of a virtual NW in which a bottleneck exists. As shown in FIG. 14, the virtual OS 41, the server, and the storage are connected by a physical link.

  The block of the double frame by which the oblique line was shown between the frames shown in FIG. 14 means the bottleneck countermeasure location. The bottleneck handling location is a location directly or indirectly related to handling the bottleneck that has occurred. The same applies to the other drawings.

  As shown in FIG. 14, since a 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 the bottleneck in the Router is related to Storage. Since the cause of the bottleneck is related to Storage, it can be seen that the handling method of adding resources to the virtual OS 41 is not an appropriate handling method.

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

  In the normal management technology of the NFV service chain, only the relationship between a physical server and a virtual server running on the physical server is used. That is, the relationship between the virtual server and the storage or firewall further used by the virtual server is not used.

  However, in the method of displaying only the virtual NW configuration as illustrated in FIGS. 13 to 14, the cause of the bottleneck may not be displayed. When the cause of occurrence of the bottleneck is not displayed, the user cannot deal with the cause of occurrence. There are cases where other bottlenecks that exist in the system cannot be resolved simply by adding resources to the virtual OS where the bottleneck exists without addressing the cause.

  Patent Document 3 discloses a performance monitoring system, a bottleneck determination method, and a management computer that determine a bottleneck in consideration of physical resource allocation policies and effects on software in a system in which a plurality of virtual machines share physical resources. Is described. However, in the technique described in Patent Document 3, it is assumed that only a bottleneck in a system in which a plurality of virtual machines share physical resources is determined, and it is assumed that a bottleneck in the NFV field is determined. Not.

  Patent Document 4 describes a virtual network operation status display device that manages the relationship between a virtual network and a lower layer network of the virtual network and displays the 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 of influence of 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 discriminate a location to be handled and a handling method from the displayed contents.

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

  As shown in FIG. 15, a bottleneck exists in the router and storage 61. It is assumed that the user has moved the router data stored in the storage 61 to the 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 diagram illustrating another display example of the configuration of the virtual NW in which a bottleneck exists and the configuration of the physical NW. The FireWall shown in FIG. 16 is connected to the Router via Logical Link and operates on the virtual OS 40. In addition, the virtual OS 40, the server 50, and the storage 60 are connected by a physical link.

  As shown in FIG. 16, each bottleneck in Router and Storage 61 is eliminated. But there is a new bottleneck in FireWall. In other words, it can be seen that the coping method of moving the data stored in the storage 61 to the storage 60 is a factor causing a new bottleneck in the fire wall.

  As described above, there is an operation method for monitoring a virtual OS, a server, and a storage constituting a virtual NW by using a virtual NW configuration and a physical NW configuration that are displayed together, and dealing with a bottleneck. However, there is a problem in that a new bottleneck may occur in another place by implementing the coping method. Therefore, there is a need for a system capable of presenting a user with a coping method that does not affect other parts even if implemented.

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

  Therefore, the present invention solves the above-described problem, a display system that displays a virtual NW configuration and a physical NW configuration in which bottleneck locations are shown, and a best bottleneck handling method that does not affect other locations, It is an object to provide a display method, a display program, and a virtual system.

  The display method according to the present invention detects a first performance degradation portion, which is a location where performance is degraded, from among virtual components constituting a virtual network included in a virtual system, and among the physical components constituting the virtual component. The second performance degradation point, which is the location where the performance has deteriorated, is detected, the related performances of the first performance degradation point and the second performance degradation point are recovered at the same time, and the new performance degradation point is not generated.

Embodiment 1. FIG.
[Description of configuration]
Embodiments of the present invention will be described below 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. Note that the number of HW measurement units included in the display system 100 may be other than four.

  In the present embodiment, the system that is the display target of 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, Server and Storage exist in the physical layer of the virtual system 200.

  The virtual network is composed of FireWall, Router, NAT, and DPI. Note that FireWall, Router, NAT, and DPI shown in FIG. 1 are network applications (hereinafter referred to as NW applications) having functions of communication devices that control the network.

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

  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 a physical link. The physical NW in the physical layer includes 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 a performance value in the virtual NW. Based on the measured performance value, the NW measurement unit 101 detects a bottleneck existing in the virtual NW. As illustrated in FIG. 1, the NW measurement unit 101 detects a bottleneck that occurs in FireWall, Router, NAT, and DPI. Hereinafter, a location where a bottleneck exists is referred to as a bottleneck location.

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

  The NW measurement unit 101 also detects a bottleneck by receiving a notification (notification) or an alert from a bottleneck location, in addition to measuring a performance value from a virtual device and detecting a bottleneck. Good. When the NW measurement unit 101 receives a notification from the bottleneck location, the bottleneck may be detected by the virtual device itself in which the bottleneck exists or by a management system that manages the virtual device.

  The HW measurement units 111 to 114 have a function of measuring performance values from NW applications such as FireWall and Router to Storage. Based on the measured performance value, the HW measurement units 111 to 114 detect bottlenecks. Similar to the NW measurement unit 101, the HW measurement units 111 to 114 may detect a bottleneck by receiving a notification or an alert.

  As illustrated in FIG. 1, the HW measurement unit 111 detects a bottleneck that occurs in the FireWall, the virtual OS 10, the Server 20, and the Storage 30. Further, 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 that occurs in the DPI, virtual OS 12, Server 22, and Storage 32. A bottleneck generated in NAT is detected by the HW measurement unit 113 (not shown).

  The bottleneck determination unit 121 has a function of determining the influence of a bottleneck and 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 a location where performance has deteriorated.

  The display unit 131 has a function of displaying the 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 the bottleneck portion is indicated. The displayed configuration diagram of the virtual system 200 shows the configuration of the virtual network in the virtual layer and the configuration of the physical network in the physical layer. 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 according to 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.

  In addition, 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 of 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 measuring unit 101 detects a bottleneck portion of the virtual NW. After the detection, the NW measurement unit 101 transmits measurement data to the bottleneck determination unit 121 (step S101). As shown in FIG. 1, in this embodiment, the NW measurement unit 101 detects a Router as a bottleneck location.

  Next, the HW measurement units 111 to 114 measure the processing time in each component from the NW application that is the measurement target to the Storage, for example. By measuring the processing time, the HW measuring units 111 to 114 detect the bottleneck portion. After the detection, the HW measurement units 111 to 114 transmit measurement data to the bottleneck determination unit 121 (step S102). Note that 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 the FireWall, virtual OS 10, Server 20, and Storage 30, respectively. In addition, the HW measurement unit 112 measures processing times in the Router, the virtual OS 11, the Server 21, and the Storage 31. The HW measurement unit 114 measures the processing time in the DPI, virtual OS 12, Server 22, and Storage 32, respectively. As shown in FIG. 1, in this 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 portions detected by the NW measurement unit 101 and the HW measurement units 111 to 114 are shown (step S103).

  For example, the display unit 131 displays a configuration diagram of the virtual system 200 on a screen provided in the display system 100. In addition, the display unit 131 may display the configuration diagram of the virtual system 200 on the screen of a user terminal that is 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 diagram illustrating a display example of the virtual system 200 by the display unit 131 according to the first embodiment.

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

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

  The bottleneck determination unit 121 determines a coping method that can be implemented 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 each component, and the like. Further, 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 in addition to the setting contents of the system configuration. The bottleneck determination unit 121 determines a plurality of candidates for a coping method for the found cause of the bottleneck.

  The bottleneck determination unit 121 determines whether or not there is no influence by executing each determined countermeasure method candidate based on the values measured by the NW measurement unit 101 and the HW measurement units 111 to 114. The effect of implementing the coping method is, for example, that a new bottleneck occurs in another location.

  When there is a coping method candidate that is not affected by the implementation, the bottleneck determination unit 121 indicates in the configuration diagram of the virtual system 200 that the coping method that has no effect on the display unit 131 and that there is no effect by the implementation. Send instructions to indicate. If there is no candidate for a coping method that is not affected by the implementation, the bottleneck determination unit 121 may transmit an instruction indicating an optimum coping method among the candidates.

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

  When the bottleneck determination unit 121 determines that there is a candidate that can reduce the resource, the display unit 131 displays a configuration diagram of the virtual system 200 that shows the candidate that can reduce the resource (step S105). Note that 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 determination unit 121 can determine a coping method as shown in FIGS. 4 to 6 in consideration of the entire system.

  FIG. 4 is an explanatory diagram illustrating another display example of the virtual system 200 by the display unit 131 according to the first embodiment. FIG. 4 shows a configuration diagram displayed on the display unit 131 when it is considered to simply add a resource to the storage 31 as a coping method. FIG. 4 shows that a resource is added to the storage 31 as a coping method. It is also shown that when the presented coping method is implemented, the bottleneck is resolved without affecting other parts.

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

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

  FIG. 5 shows that the server on which the virtual OS 11 operates is changed from Server 21 to Server 22 as a coping method. The server on which the virtual OS runs is changed by, for example, migration processing using VMware (trademark registered) VMotion. It is also shown that when the presented coping method is implemented, the bottleneck is resolved without affecting other parts, particularly the server 22.

  As described above, the bottleneck determination unit 121 can grasp in advance the influence of the resource allocation change on other locations. 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 change the resource allocation without causing a new bottleneck. By changing the resource allocation, the bottleneck of the entire system is eliminated.

  FIG. 6 is an explanatory diagram illustrating another display example of the virtual system 200 by the display unit 131 according to 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 process only up to three times the current processing amount. Next, the bottleneck determination unit 121 determines that the amount of resources allocated to other locations can be reduced to an amount capable of processing a processing amount that is three times the current processing amount. After considering the reduction amount, the bottleneck determination unit 121 outputs a location where a reducible resource is allocated and a reducible resource value.

  More specifically, if 33% of the total processing capacity of the storage at the bottleneck is used, the storage at the bottleneck will only be up to three times the current processing amount at the maximum. It cannot be processed. In other words, no matter how much the performance of the entire system is improved, the amount of processing in other components is not more than tripled.

  Assume that 10 CPUs are allocated as resources to other virtual OSs, and the current CPU usage rate of the other virtual OSs is 20%. When the current processing amount is tripled, the CPU usage rate of 10 CPUs is 60%. Therefore, even if the current processing amount triples, if 6 CPUs are allocated, the CPU usage rate of other virtual OSs does not exceed 100%, so up to 4 CPUs from other virtual OSs It is judged that it can be reduced.

  FIG. 6 shows that as a coping method, the resources allocated to the storage 30 and storage 32 are reduced as much as possible, and the reduced resources are allocated to the storage 31. In addition, it is shown that the resources allocated to the virtual OS 10 and the virtual OS 12 are reduced to the maximum, and the reduced resources are allocated to the virtual OS 11. It is also shown that when the presented coping method is implemented, the bottleneck is resolved without affecting other parts, in particular, the virtual OS 10, the virtual OS 12, the Storage 30 and the Storage 32.

  As shown in FIG. 6, resources allocated to other locations are reduced as much as possible according to the performance value of the cause of the bottleneck, thereby improving resource allocation efficiency in the entire system.

  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 indicated that there is no influence by the execution, the display system 100 ends the processing.

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

  The display unit of the display system according to the present embodiment displays the logical configuration including the virtual network path and the virtualized server configuration and the physical configuration including the network path and the server configuration in parallel. As a result of the display, the user can know the correspondence between the bottleneck existing in the logical configuration and the bottleneck existing in the physical configuration, and can identify the cause of the bottleneck existing in the entire system. In addition, by knowing the correspondence, the user can also identify other places where 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 configure the virtual OS, Server, Storage, etc. It is possible to clearly determine what to deal with in which part. The reason is that the logical configuration and the physical configuration are displayed in parallel, so that the cause of the bottleneck is clear and the user can deal with the cause.

  In addition, the display unit of the display system according to the present embodiment can present an appropriate coping method for the cause of the bottleneck. As a coping method, for example, an appropriate resource enhancement for the cause of the bottleneck is presented. Also, a method is presented in which resources allocated to locations other than the cause of the bottleneck are reduced as much as possible, and the reduced resources are allocated to the cause.

  As a coping method presented in addition to adding resources, if the storage is in the physical layer, for example, the data stored in the partition that is the bottleneck location is processed in a memory with higher I / O performance. Data relocation or partition reconfiguration for Also, to relatively increase the priority of processing requests received from the virtual OS that is the bottleneck location, or to relatively lower priority of processing requests received from virtual OSs other than the virtual OS that is the bottleneck location There is a change in storage settings.

  In addition, as a countermeasure to be presented, for reducing the priority or frequency of requests from virtual OSs other than the virtual OS that is the bottleneck location among the virtual OSs that send requests to the storage that is the bottleneck location There is a change in the setting of the virtual OS or the host server of the virtual OS.
