Description

  The present invention relates to a distributed system analysis apparatus and program for performing an operation analysis of a distributed system.

  There is a distributed system in which a plurality of program parts are centrally operated by arranging a plurality of program parts in a controller or the like of a plurality of apparatuses connected via a network and operating the program parts in cooperation with each other. Such a system includes, for example, various measuring instruments (for example, a thermometer, a hygrometer, a pressure gauge, etc.) and various driving devices (for example, a heater driving switch, a valve driving device for adjusting a flow rate, a robot arm) in a factory production facility. For example, Patent Document 1).

  At the stage of design and construction of the distributed system, the system builder decides where to place each program component, and the device resources required for each program component (for example, the capacity of the storage device or memory, CPU load, usage I / O O) and network resources (network port, network bandwidth, etc.) are reserved, it is necessary to know how much performance and characteristics each program component requires from the device controller and network. It becomes.

  As a method of grasping the resource environment required for each program component, for example, a distributed system is actually operated or a simulation operation is performed to measure how much resources are used. A method is conceivable.

  Further, as a method of grasping the resource environment required for each program part without performing the actual operation or simulation of the distributed system, there is a method of calculating from the required resource data indicated in the specification information of each program part.

  When a software developer develops a program part, the specification information by the developer indicates how much resource environment (for example, CPU load, storage device and memory capacity, usage I / O) is required. Is normal. Therefore, for example, when a plurality of program parts are arranged in one device, a plurality of program parts can be obtained by adding the requested resource data indicated in the specification information of each program part for the plurality of program parts. Can greatly grasp the resource environment required.

Conventionally, for a plurality of program parts arranged in one device as described above, there is a design support tool that extracts data of each required resource from the specification information of each program part, adds them, and presents them to the system builder. there were.

  In order to grasp the resource environment required for program parts, if a method of actually operating a distributed system and measuring the resource usage status is prepared, a real environment for actually operating the program parts is prepared and measured. Since it is necessary to verify the influence of the apparatus on the device, there arises a problem that it takes a lot of cost and time. In addition, even if the method of analyzing the resource usage status by simulation, it is necessary to construct a virtual environment for simulation or to create a simulation model of the measurement target element, which results in significant cost. And a problem that it takes time.

  Further, in the method of obtaining the resource environment required from the specification information of the program parts as in the conventional design support tool, the resource environment data required for each program part in the actual operation cannot be obtained accurately.

Only the information on the maximum / minimum resource environment (for example, the minimum value of the memory usage, the maximum value of the CPU load, etc.) used during the operation.

  Therefore, only with the required resource data indicated in the specification information, information on the resource environment used in the cooperative operation between program parts whose communication frequency and communication data amount vary depending on the operation setting etc. can be obtained. I can't. Therefore, by simply adding the required resource data indicated in the specification information of each program part, it is possible to obtain accurate required resource data that reflects the actual operation situation in which multiple program parts operate in cooperation with each other. I can't.

  The controller of the device constituting the distributed system has very few resource environments such as CPU processing capacity, storage device and memory capacity, etc., compared to general-purpose computers and server devices. Therefore, if the resource environment that is actually used during the operation of the distributed system cannot be accurately grasped, excessive program parts may be placed in the controller of the device and an operation error may occur due to a resource shortage, or an excessive resource environment will be secured. Therefore, there is a problem that the arrangement of other useful program parts is hindered by the excessive arrangement of program parts in the controller of the device.

It is determined whether an alarm is issued for the measured data. For each data transfer, a transfer response indicating whether the data transfer has been normally performed from the transfer destination is made.

  In the application construction support apparatus 1, data processing components as shown in FIG. 4 are constructed with respect to the application configuration of FIG. 3. That is, a plurality of functional component management modules B1a to B1c and a plurality of linkage influence relationship information 34a to 34c are set corresponding to the respective functional component instances 5a to 5c, and further, corresponding to each of the connected portions M and N. A plurality of pieces of cooperative usage information 33m and 33n are set.

  And each functional component management module B1a-B1c performs the data production | generation of the cooperation utilization information 33m and 33n for every end point of the connection parts M and N, and a data update, and also contains the data operation content of this cooperation utilization information 33m and 33n. Accordingly, the data contents of the linkage influence relationship information 34a to 34c are generated or updated.

Next, a specific processing procedure for calculating the environmental requirement information for the above application configuration will be described for each step according to the flowchart of FIG.
(Step S1)

The application construction support apparatus 1 receives the AP environment request information calculation request from the operator via the environment request information calculation request UI 11, and the AP environment request information estimated value calculation function 12 starts the calculation process of the environment request information.
(Step S2)

  When the environmental request information calculation process is started, first, the AP environmental request information estimated value calculation function 12 receives from the functional component instance setting information DBA1 the functional components for all functional component instances 5a to 5c constituting the distributed system. The identification information of the program module is read, and a plurality of functional component management modules B1a to B1c (FIG. 4) corresponding to all the functional component instances 5a to 5c (FIG. 3) are set based on this identification information.

  Further, the AP environment request information estimated value calculation function 12 reads the information on the connection configuration of the functional component instances 5a to 5c from the functional component instance linkage relation information DBA2, and based on this information, all the connected parts M, A plurality of cooperative usage information 33m and 33n (FIG. 4) corresponding to N (FIG. 3) are set in the cooperative usage information DBA3. Also, a plurality of pieces of linkage influence relationship information 34a to 34c (FIG. 4) corresponding to the respective functional component instances 5a to 5c (FIG. 3) are set in the functional component instance linkage relationship information DBA2. As a result, the components for data processing shown in FIG. 4 are prepared.

  When such preparation is completed, the AP environment request information estimated value calculation function 12 then obtains the operation setting information of each functional component instance 5a-5b from the functional component instance setting information DBA1 and the corresponding functional component management module B1a. To B1c. Then, a request for calculation of initial data of the cooperative usage information 33m and 33n is made to these functional component management modules B1a to B1c. Based on this calculation request, the functional component management modules B1a to B1c receive the information on the resources used (information related to the traffic) of the connected portions M and N resulting from the operation settings of the functional component instances 5a to 5b. , N are calculated for each end point and written as initial data of the cooperative usage information 33m, 33n.

  FIG. 6 shows an example of the initial data of the cooperative usage information calculated by the functional component management module. As shown in the figure, two sets of data (1) and (2) having “data collection function” and “data storage function” as endpoints are registered in the cooperative use information 33m of the connection part M, and the connection part Two sets of data (3) and (4) having “data storage function” and “alarm notification function” as endpoints are registered in the N cooperative use information 33n.

  Since the functional component instance 5a of the “data collection function” performs communication of the “data storage request” resulting from its own operational setting in the connected part M, the functional component management module B1a analyzes the operational setting and obtains information Data values such as the transfer frequency “every 100 msec” and the average data amount “3 KB” per unit transfer are determined, and this data is registered in the cooperative usage information 33m.

  In the functional component management module B1b, the functional component instance 5b of the “data storage function” performs “data change notification” communication in the connected portion N, but this communication amount is not determined from its own operation setting. In the cooperative usage information 33n, the information transfer frequency and the average data amount remain undecided.

  In the functional component management modules B1b and B1c, the functional component instances 5b and 5c of the “data storage function” and the “alarm notification function” perform response transmission due to their own operation settings in the connection portions M and N, respectively. Therefore, by analyzing each of these operation settings, the average data amount “0.1 KB” for each unit transfer related to response transmission is determined, and this information is registered in the cooperative usage information 33m and 33n. On the other hand, the frequency of response depends on the frequency of data transfer from the communication partner and is not determined from the above-described operation settings, so it remains undecided.

  Each of the functional component management modules B1a to B1c also performs data generation of the cooperation influence relationship information 34a to 34c along with the data generation of the above-described cooperation usage information 33m and 33n.

  FIG. 7 shows an example of initial data of cooperation influence relationship information calculated by the functional component management module.

  As shown in FIGS. 4 and 7, the cooperation influence relationship information 34 a to 34 c includes data indicating the correlation between each functional component instance 5 a to 5 c and one or a plurality of connected portions M and N attached thereto, In other words, the “effect of functional component setting” data indicating whether or not the operation settings of the functional component instances 5a to 5c have an influence on the communication of the connected parts M and N, and the communication of the attached connected parts M and N is a functional component. “Influence on functional parts” data indicating the presence / absence of the influence on the cooperative operation of the instances 5a to 5c, and “Influence” indicating the presence / absence of the influence of the communication of one attached part on the communication of the other connected part "Linked part of cooperative use information" data is registered.

  Each of the functional component management modules B1a to B1c determines whether or not the data values of the cooperative usage information 33m and 33n have been affected by the operation setting of the functional component instances 5a to 5c at a step S2, and this determination is made. Based on the above, the data value of “influence of functional component setting” of the linkage influence relationship information 34a to 34c is determined.

  For example, as shown in FIG. 7, in the linkage influence relationship information of the linked portion M corresponding to the “data storage function”, the data value of “effect of functional component setting” is determined as “none”, and other data items Is left undecided. As the operation setting of the functional component instance 5b of the “data storage function”, the data value of the cooperative usage information 33m is determined by the setting information “average data amount of data storage request response / unit transfer”. It is determined that “0.1 KB” is not an influence beyond a certain level, and the data value of the “effect of functional component setting” is set to “none”.

In step S <b> 2, the determination of the data value of “influence of functional component setting” as described above is performed for all the linkage influence relationship information 34 a to 34 c.
(Step S3)

  Next, the AP environment request information estimated value calculation function 12 refers to the functional component instance linkage relationship information DBA2, grasps each link relationship of the functional component instances 5a to 5c, and currently calculates each linked usage. The information 33m and 33n are sent to the functional component management modules B1a to B1c corresponding to the functional component instances 5a to 5c of the connection destinations.

As a result, for example, the cooperative usage information 33m of the connected part M of the “data collection function” is passed to the functional part management module B1b of the “data storage function”, or to the functional part management module B1c of the “alarm notification function”. The link usage information 33m of the connected portion N of the “data storage function” is passed.
(Step S4)

  Next, the AP environment request information estimated value calculation function 12 requests the functional component management modules B1a to B1c to calculate the link usage information 33m and 33n and the link influence relationship information 34a to 34c again.

  FIG. 8 and FIG. 9 show an example of the update data of the cooperation usage information and the cooperation influence relation information calculated by the functional component management module.

  When the above calculation request is made again, each of the functional component management modules B1a to B1c refers to the cooperation usage information 33m and 33n of the cooperation destination input in step S3, and calculates the cooperation usage information 33m and 33n to be calculated. Calculation processing is performed for data items that are undecided.

  For example, as illustrated in FIG. 8, the functional component management module B1b includes “information transfer frequency” and “average data amount of information transfer / unit transfer” in the cooperative usage information of the connected portion N of the “data storage function”. Is calculated based on the other cooperative usage information 33m input in step S3. These data items are determined at the stage of step S2 because the data values are determined due to the communication amount of the data storage request from the “data collection function” ((3 in FIG. 6). )), And can be calculated by passing the data value related to the communication amount of the data storage request from the “data collection function” in step S3.

  Specifically, the functional component management module B1b changes the value of the “information transfer frequency” related to the data change notification from the operation specification of the functional component instance 5b of the data storage function to the data storage request of the “data collection function”. Since the dedicated logic is set to have the same value as the “information transfer frequency”, the data value of the cooperative usage information 33m of the cooperation destination is referred to according to the dedicated logic, and “ The data value of “information transfer frequency” is calculated as “every 100 msec”.

  Further, the functional component management module B1b determines the value of “average data amount / unit transfer” related to the data change notification from the operation specification of the functional component instance 5b of the data storage function, and the average of the data storage request of the “data collection function”. Since the dedicated logic is assembled so that the data amount is obtained by subtracting “1 KB” from the data amount, referring to the data value of the cooperative usage information 33m of the cooperation destination and a predetermined calculation are performed according to this dedicated logic, The data value of “average data amount / unit transfer” of the cooperative usage information 33n to be calculated is calculated as “2 KB”. These data values are added to the cooperative usage information 33n to be calculated.

  According to the recalculation processing of the cooperative usage information 33m and 33n, when the cooperative operation is performed in a multistage manner with the plurality of functional component instances 5, the next step is calculated from the cooperative usage information related to the previous cooperative operation that has been calculated. The cooperative usage information related to the cooperative operation is calculated.

  Furthermore, the functional component management modules B1a to B1c also update the data values of the corresponding cooperative influence relationship information 34a to 34b according to the operation content of the cooperative usage information 33m and 33n. That is, whether or not the cooperation value of the corresponding functional component instance has been affected by the data value of the cooperation usage information related to the cooperation destination given as input information, or whether the cooperation related to the cooperation destination given as input information It is determined whether or not the data value of the usage information has influenced the data value of the linked usage information of the other connected portions beyond a certain level, and the data of the corresponding linkage impact relationship information 34a to 34c is determined according to the determination result. Update.

  Specifically, as shown in FIG. 9, for the data related to the linked portion M of the linkage influence relationship information 34 b of the “data storage function”, the “data storage function” from the linkage usage information 33 m of the “data collection function”. Since the data value of the link usage information 33m of the connected portion M of the link is more than a certain value, the functional component management module B1b determines the “influence on functional components” related to the link portion M of the link impact relationship information 34b. The data value is “present”.

In addition, since the data value of the link usage information 33n of the linked part N of the “data storage function” is influenced more than a certain amount from the link usage information 33m of the “data collection function”, the functional component management module B1b The data value of “the connected part of the influential cooperative use information” related to the connected part M of the influence relationship information 34b is set to “connected part N”.
(Step S5)

  When the recalculation of the cooperative usage information 33m and 33n is completed, the AP environment request information estimated value calculation function 12 confirms whether or not the cooperative usage information 33m and 33n has been updated by the recalculation in step S4. Returning to step S3, the processes of steps S3 and S4 are repeated.

  By repeating the processes in steps S3 and S4, when a plurality of functional component instances 5 perform a cooperative operation in multiple stages, the cooperative usage information related to the cooperative operation of each stage is calculated step by step from the first stage. This is repeated a plurality of times, so that the calculation of the cooperative use information related to the cooperative operation at the last stage is performed. In addition to the calculation of the cooperative usage information, the cooperative influence relation information related to each cooperative operation is also calculated.

  And if all the cooperation use information of each step | level of the cooperation operation | movement linked to such a several step is calculated, even if the process of step S3, S4 is repeated, a cooperation use information will no longer be updated. That is determined in the process. If it is determined in the determination process in step S5 that the cooperative usage information has not been updated, the process proceeds to the subsequent step S6.

  Note that, for example, when the cooperative operation reciprocates between the two functional component instances 5, or when multiple functional cooperative instances 5 are linked in a loop, the steps S3 and S4 are repeated. It is conceivable that the cooperative usage information is constantly updated by this processing, and the data value of the cooperative usage information does not converge. Therefore, for the cooperative operation in which such a situation is assumed, the functional component management module B1 does not calculate the cooperative usage information based on the operational specification of the functional component instance 5 in the calculation process of step S4. You may comprise so that the rough estimate of cooperation utilization information may be calculated based on a fixed condition setting.

  FIG. 10 is a chart showing an example of a method for estimating cooperative usage information when the cooperative operation reciprocates.

  For example, the data storage request response is made frequently from the functional component instance 5b of the “data storage function”, and an NG data storage request response is made at a certain rate, and the functional component instance of the “data collection function” is sent by this NG response. Assume a cooperative operation in which 5a retransmits measurement data.

  In this case, the cooperative operation reciprocates between the functional component instance 5a of the “data collection function” and the functional component instance 5b of the “data storage function”, so that the functional component management modules B1a and B1b can only operate. When recalculation of the cooperative usage information 33m in step S4 is performed based on this, the cooperative usage information 33m does not readily converge.

  Therefore, for a cooperative operation in which response communication for such data transfer and data retransfer by NG response are performed, for example, as shown in FIG. 10, data retransfer is constant according to the frequency of response communication. It is possible to adopt an estimation method that is performed with the amount of data. In the example of FIG. 10, if the data storage request response from the functional component instance 5 b of the “data storage function” is performed in 100 msec or less, the data retransfer of “1 KB” is performed from the functional component instance 5 a of the “data collection function”. As an operation to be performed, an approximate process for adding this amount of data is performed. Similarly, as shown in each row of the chart of FIG. 10, the frequency of data storage request response is divided by a predetermined threshold value, and the addition amount of the data amount related to data retransmission is determined for each division.

  As described above, when the approximate value of the calculation data is changed according to the condition of each cooperative operation, as shown in FIG. In addition to the method in which the approximate values are made different from each other, various state quantities and conditions may be connected by logical product / logical sum, etc., so that an approximate approximate value for each state quantity or condition may be obtained.

The function for approximating the calculation data as described above may be incorporated in the dedicated logic of the functional component management module B1, for example, or, in addition, the application construction support apparatus 1 may have an external function module management module B1. A function that replaces the calculation process of the cooperative usage information by the functional component management module B1 with an approximate process may be added by finding a connected portion where the cooperative usage information does not converge.
(Step S6)

  After all the cooperative usage information 33m and 33n and the cooperative influence relation information 34a to 34c are calculated, the AP environment request information estimated value calculation function 12 then performs a cooperative operation on each functional component management module B1a to B1c. The environmental requirement information of the functional component instances 5a to 5c including the used resources is calculated. Further, each cooperation management module B2 is made to calculate the environmental request information necessary for the communication network of each of the connected parts M and N.

  Specifically, the AP environment request information estimated value calculation function 12 includes the cooperative usage information 33m and 33n calculated by the processes in steps S2 to S5 and the functional component instances 5a to 5c in the functional component instance setting information DBA1. The setting information and the setting information of each connected part in the functional component instance linkage relationship information DBA2 are read and sent to the corresponding functional component management modules B1a to B1c and the linkage management module B2.

  The functional component management modules B1a to B1c first, based on the setting information of the functional component instances 5a to 5c, the CPU load, storage area, memory capacity, usage I / I required for the internal processing of the functional component instances 5a to 5c. O and the like are calculated. Furthermore, the CPU load, storage area, and memory used in the communication processing (data encoding / decoding, encryption processing, etc.) of each of the cooperation interfaces 6a to 6d from the cooperation usage information 33m, 33n and the setting information of each of the connected portions M, N Calculate capacity. In this case, the format of data transmission / reception is grasped by the setting information of each connected part, the amount of data transmission / reception is grasped by the cooperative use information 33m, 33n, and the information of the resource environment necessary for the cooperative operation can be calculated from these.

  Also, the cooperation management module B2 calculates the network bandwidth necessary for data transmission / reception performed by each of the cooperation interfaces 6a to 6d, the allowable delay of data transfer, and the like from the cooperation usage information 33m and 33n and the setting information of each connection part.

  FIG. 11 shows an example of the environment request information of each functional component instance stored in the program instance environment request information DBA5, and FIG. 12 shows the communication network of each connected part stored in the program instance environment request information DBA5. An example of the environmental requirement information (network load) is shown.

As shown in FIG. 11, the AP environment request information estimated value calculation function 12 collects the individual environment request information calculated by the functional component management modules B1a to B1c for each functional component instance 5a to 5c. As shown in FIG. 12, the communication network environment request information calculated by the cooperation management module B2 is collected for each of the connected portions M and N, and these processed data are stored in the program instance environment request information DBA5.
(Step S7)

  Next, the AP environment requirement information estimated value calculation function 12 uses the functional component instances 5a to 5c constituting the distributed system and their connection parts M and N as individual elements, and each element is influenced by the cooperative operation. The other elements that are received and the other elements that each element affects through the cooperative operation are calculated (influence relationship calculating means). In these calculation processes, the calculated linkage influence relationship information 34a to 34c is read from the linkage influence relationship information DBA4, and information on the presence / absence of an influence on an adjacent element indicated in the linkage influence relationship information 34a to 34c is sequentially traced. It can be accomplished by following.

  For example, the functional part instance 5c of the “alarm notification function” can first be determined to be affected by the connected portion N from the data value of the linkage influence relationship information 34c (FIG. 4), and then the linkage influence relationship information 34b. From this data value, it can be determined that the connected portion N is affected by the connected portion M. Further, it can be determined from the data value of the cooperation influence relationship information 34a that the connected portion M is influenced by the operation setting of the functional component instance 5a of the “data collection function”. By linking these, the AP environment request information estimated value calculation function 12 is an element that affects the functional part instance 5c of the “alarm notification function”, the functional part instance 5a of the “data collection function”, and The connecting part N can be selected.

The AP environment request information estimated value calculation function 12 calculates such processing for all elements, and lists each element. Then, the environmental requirement information data calculated in step S6 and the influence relationship data calculated in step S7 are passed to the environmental requirement information display UI14.
(Step S8)

  FIG. 13 shows an example of an output display of environment request information of the distributed system by the environment request information display UI.

  The environment request information display UI 14 processes the data passed in step S7 for display output, and performs display output as shown in FIG. 13, for example. For example, for each functional component instance 5a to 5c, a functional component display frame 51 listing "environment requirement information", "affected elements", and "influencing elements", and each connecting portion M, For each of the N endpoints, an information display including a “linkage communication transmission amount information”, an “affected element”, and a linked use information display frame 52 listing “influencing elements” is displayed. Is called.

  By such information output, the system builder does not actually operate the distributed system or perform a simulation operation, but reflects the actual operating status of the distributed system required for each functional component instance 5a to 5c. Can be obtained in a short time. In addition, it is possible to quickly grasp the elements that are affected or affected by the cooperative operation in each functional component instance 5a to 5c and each connected portion.

  Thereby, the system builder can efficiently select the placement destination of the functional component instances 5a to 5c when the distributed system is constructed. For example, it becomes easy to examine the placement destinations of the functional component instances 5a to 5c in consideration of the performance of the distributed system and load distribution, thereby reducing the time for system construction work and the cost.

Further, it is possible to efficiently reserve resources of devices and networks necessary for the normal operation of the application configuration of the distributed system, based on the estimated values of the environmental requirement information of the functional component instances 5a to 5c and the connected portions M and N. It becomes possible. As a result, for example, during the investigation and adjustment of the distributed system, the operation adjustment and change work of the application configuration is simplified, and the operational risk of the distributed system and the cost of changing the system configuration can be reduced.
[Second Embodiment]

  The application construction support apparatus of the second embodiment analyzes the influence relationship between each element of the distributed system in more detail than the first embodiment. The other configuration is the same as that of the first embodiment, and the description of the same configuration as that of the first embodiment is omitted.

  FIG. 14 shows an example of cooperation influence relationship information generated by the functional component management module of the second embodiment.

  In the second embodiment, in order to analyze the influence relationship between each element of the distributed system in more detail, the data content of the cooperative influence relation information in which the information on the influence relation between each element is registered is made more detailed.

  As shown in FIG. 14, in the cooperation influence relationship information 35 a and 35 b of the second embodiment, one piece of cooperation influence relation information is generated for each functional component instance 5, The point that a set of data is generated for each connected portion when there is a connected portion is the same as in the first embodiment. In addition, as the data items, a data item of “effect of functional component setting” representing an influence relationship of the operation setting of the functional component instance 5 on the communication of the connected portion, and the influence of the communication of the connected portion on the functional component instance 5. The data item “influence on functional parts” representing the relationship and the relation of influence on the communication of other connected parts from the communication of one connected part attached to the functional part instance “ The point that the data item of “connected portion” is provided is the same as that of the first embodiment.

  As a difference from the first embodiment, first, in the cooperation influence relationship information 35a, 35b of the second embodiment, the above-mentioned “effect of setting functional parts”, “effect on functional parts”, “influence” The data values of the three items “linkage portion of cooperative usage information” are generated separately for each of the communication frequency of the corresponding link portion and the data transfer amount of the corresponding link portion.

  Furthermore, the data contents of “effect of functional component setting” and “effect on functional component” indicate not only information indicating the presence / absence of the influence but also the contents of the operation setting of the affected functional component instance 5. Detailed contents such as information (for example, operation cycle and usage I / O) and information (CPU load, storage area, memory capacity, etc.) indicating the contents of the affected resource environment are included.

  In addition, the data content of the “linked part of linked usage information that affects” is not information that simply specifies the connected part, but can be specified by distinguishing the communication frequency of the connected part and the data transfer amount of the connected part. Has been.

  The data contents of the cooperative influence relationship information 35a and 35b are stored in the functional component instance 5 stored in the functional component instance setting information DBA1 when the functional component management module B1 manipulates the data content of each cooperative usage information. Can be calculated by the functional component management module B1 on the basis of the information on the operation setting and the communication setting information of each connected portion stored in the functional component instance linkage relationship information DBA2. In the second embodiment, by using such a dedicated logic incorporated in the functional component management module B1 and incorporating such a calculation function, the cooperative influence relationship information 35a and 35b as shown in FIG. 14 is generated. It has become so.

  In the application construction support apparatus of the second embodiment, the environmental requirement information shown in FIG. 13 of the first embodiment is further provided to present the operator with a more detailed analysis result regarding the influence relationship between the elements of the distributed system. Can be expanded to a more detailed level of data content.

  FIG. 15 shows an example of detailed display of environmental request information by the environmental request information display UI of the second embodiment.

  Specifically, in the environment request information output screen of FIG. 13, the operator selects one functional component instance from the functional component display frame 51 via the input device, and requests detailed data display. A detailed display 55 as shown in FIG. 15 is made. The display example of FIG. 15 represents a case where a functional component instance of “alarm notification function” is selected on the output screen of FIG. 13 and a detailed display request is made.

  As shown in FIG. 15, in the detailed display 55 of environmental request information, individual environmental request information (CPU load, memory, storage area, etc.) of the selected functional component instance is set as a “state item”, and each status item request is displayed. 15 ("current state value" in FIG. 15) and the contents of the operation setting in each functional component instance 5 or connection part affecting the requested value of each state item ("related item setting value" in FIG. 15) ) Data is listed.

  For example, in the display example of FIG. 15, the required value of the CPU load of the functional component instance 5c of the “alarm notification function” is “30%”, and the factor that affects this CPU load is the “alarm notification function”. The operational setting of the notification style of the functional component instance 5c is “mail”, the operational setting of the measurement data collection cycle of the functional component instance 5b of the “data collection function” is “50 msec”, and the “data collection function” The use I / O setting of the functional component instance 5a is “AI0-AI15 (address in), DI0-DI7 (data in)”, and the communication encryption method setting of the connected part M is “RSA”. It is shown to be a point. For the memory and the storage area, the requested value and the contents of the operation setting affecting the same are shown in the same format.

  Although not shown, by selecting one connection part from the cooperative usage information display frame 52 of FIG. 13, each environment request information (communication frequency, average data) corresponding to this connection part is similarly selected. Quantity etc.) is registered in the “status item”, and the required value of each status item and the contents of the operation settings of each functional component instance and each connected part affecting the required value of each status item are listed. Is output.

  Information on the operation settings of the functional component instances 5a to 5c, the operation settings of the connected parts M and N, and the connected parts M and N affecting the individual required resources of the functional part instances 5a to 5c. The information on the operation settings of the functional component instances 5a to 5c and the operation settings of the connected parts M and N that affect the individual request resources of the AP environment request information estimated value calculation function 12 is provided by the second embodiment. .. Are read, and information on the influence relationship with the adjacent elements shown in the link influence relationship information 35a, 35b,... Is sequentially calculated. Is transferred from the AP environment request information estimated value calculation function 12 to the environment request information display UI 14.

  According to the detailed display 55 of the environment request information as described above, the system builder has an influence on the individual resource environment required for each of the functional component instances 5a to 5c and each of the connected portions M and N. The operation settings of the other functional component instances 5a to 5c and the operation settings of the connected portions M and N can be grasped in a short time.

  After the distributed system is constructed, for example, an operation failure or an excessive load may be found in a certain functional component instance. However, such a cause is not always found in the functional component instance in which an abnormality has been found, and may be caused by operation settings of other functional component instances or operation settings of other connected parts.

  Therefore, in such a case, the detailed display 55 of the environmental requirement information of the second embodiment is output, and the requested resource of the functional component instance in which an abnormality is found, and other individual resources that have an influence on these individual requested resources By grasping the operation settings of the functional component instance and the operation settings of each connected portion, it is possible to find the cause of the occurrence of the abnormality as described above.

  For example, it is assumed that an excessive load is generated in the functional component instance 5c of the “alarm notification function” and the cause is investigated. In this case, it can be understood from the information display in FIG. 15 that the CPU load of the “alarm notification function” is as high as “30%”, and the other functional component instances 5a to 5c that are the factor of the CPU load It is possible to grasp the operation settings and the operation settings of the connecting portions M and N. For example, it is possible to find out that the measurement data collection period of the functional component instance 5a of the “data collection function” is set from the assumed value “every 100 msec” to an incorrect value “every 50 msec”.

  As described above, according to the application construction support apparatus of the second embodiment, the detailed display 55 of the environment request information is used to adjust the operation setting of each functional component instance and the operation setting of each connected part when the distributed system is constructed. Can be performed efficiently. In addition, as described above, these tasks can be performed efficiently when searching for the cause of anomalies after building a distributed system, or when investigating and adjusting a distributed system to improve performance or achieve optimal load distribution. It can be carried out.
