Description

The present invention relates to a data collection server or the like for collecting information such as materials related to business.

Generally, in order to collect various information about the operating status of the server and the details of the failure, it is possible to collect various materials including log data such as event logs and error logs from the server by the monitoring client terminal. It is done.

For example, if the user manually specifies the server to be collected, there is a technology that automatically collects the specified material from the specified server, converts the collected material into the specified format, and automatically sends it to the support center. ..

Data collection is realized by a data collection program running on the server performing data collection processing such as data collection and transfer in response to a request from the client. When this data collection program operates, a certain load is applied to the CPU, hard disk, network, and the like of the server. For this reason, there is a problem that the user has to wait until the service provided by the server is not provided, for example, on weekends or midnight, and instruct the user to collect data at that time.

In order to solve this problem, when the user instructs to collect data, the server for which failure information is collected (hereinafter, also referred to as the target server) so that the data collection does not hinder the stable operation of the server. ) Is disclosed on the client terminal side to determine the timing of collection (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-059617

In the technique described in Patent Document 1, the operator arbitrarily sets a predetermined waiting time for measuring the timing of collecting data. Therefore, the client terminal side may be able to collect data with a short standby time, or may have to wait for a long time until the load status can be collected. For this reason, it may take an unexpected amount of time to analyze the failure because the acquisition timing of data collection cannot be measured.

The present invention has been made in view of the above problems, and is a data collection system capable of shortening the waiting time until data collection without adversely affecting the processing of the entire system when collecting data from the server. Etc. are intended to be provided.

It is a flowchart which shows the operation which collects or does not collect data according to the business priority of the data collection system in embodiment of this invention. It is a figure which shows the structure of the data collection server which concerns on the 2nd Embodiment of this invention. It is a block diagram which shows the structural example of the information processing apparatus applicable in each embodiment.

With the technology described in Patent Document 1, the engineer who conducts the failure investigation cannot quickly submit the material including the log information and the data related to the failure necessary for the failure investigation from the customer or the maintenance staff in charge of the customer system. In some cases, it could have taken a long time to complete disaster recovery. Collecting materials is also called acquiring materials. This was due to the fact that maintenance personnel could not collect data while the customer system was in operation. That is, in the technique of Patent Document 1, data collection is executed quickly and automatically as long as the conditions for collecting data are met, but on the other hand, the waiting time until the conditions are met is long. There's a problem.

Therefore, in each embodiment of the present invention, the immediacy (shortest start timing) of collecting data or the shortening of waiting time is pursued. It is a business application that can be paused even if an application for business (hereinafter, also referred to as a business application) is running on the target server (customer server) of the customer system, and data collection is short. If it is completed with, even if the operation of the business application is temporarily stopped, there is no big hindrance to the customer's system as a whole. Further, in the technique described in Patent Document 1, when the load of the target server for collecting data is high, the collecting of data cannot be executed immediately. However, depending on the priority of the business application (for example, if the priority is low), the load on the target server for data collection can be increased by temporarily limiting the allocation of hardware resources such as the CPU to the business application. It is possible to intentionally lower it for a certain period of time and complete the collection of data during that period. It should be noted that, among the business applications, when the business application having a high priority for which the operation should be continued or the business application for which the highest priority should be performed is in operation, data collection may not be executed. In such a case, wait for data collection until the business application stops operating.

To explain the above concretely, it can be summarized into three plans. The first is a method in which business is stopped for a certain period of time on the customer server side and data collection is executed first. This is effective when it is determined that the data collection is completed in a short time. As a preliminary preparation, the client or the operator of the customer system may be made to list the types of materials in advance, and if any of the listed materials is to be collected, the work may be temporarily stopped and the materials may be collected. Is set in advance. When it is actually necessary to collect data, the worker collects data from the target server if the setting allows the business to be suspended for a certain period of time. At this time, the target server (hereinafter, also referred to as target server A) displays on the monitor of the terminal of the client or operator that the business will be suspended for a certain period of time, and further suspends the business for a certain period of time in this display. You may get permission from the client again. After the data collection is completed, the business application is automatically restarted.

The second method is to control (suppress) the hardware resources of the business application being executed so that the load on the customer system does not increase. That is, if the hardware load for executing the business application on the target server is high, the target server A intentionally reduces the load during the data collection and collects the data in parallel with the execution of the business application. As a preliminary preparation, a business application whose execution may be controlled is selected in advance by the operation of a client or an operator. When it is actually necessary to collect data, the target server A determines whether the load of the running business application is higher than the threshold value, and if it is determined to be high, it is used as a monitor for clients, operators, etc. Displays that the execution of business applications is controlled. At the time of this display, the target server A may obtain permission from the client again to control the application execution. After the display or when permission is obtained, the target server A suppresses the execution of the business application, reduces the hardware load of the system, and executes data collection. After the data collection is completed, the hardware load of the business application is automatically returned to the base.

The third method is to specify whether or not to execute data collection depending on which business application is running among the business applications running on the target server of the customer system. This is because the importance of business may differ for each client. In this way, the target server A is designed so that it is possible to specify whether or not data collection can be executed after prioritizing each business application included in the business application according to the client. That is, the target server A does not focus only on the hardware resources to determine the load status, but prioritizes each business application. Further, not only the customer's business application but also other application software may be added as a criterion for determining whether or not to execute data collection. As a preliminary preparation, let the client specify in advance the business application for which you do not want to execute data collection. When it becomes necessary to collect data, the target server A does not execute data collection and waits until the end of the business application while the business application for which data collection should not be performed is running. During operation, collect data immediately.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, the drawings schematically show the configuration in the embodiment of the present invention. Further, the embodiment of the present invention described below is an example, and can be appropriately changed as long as the essence of the present invention is the same.

Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.
<First Embodiment>
(Data collection system)
The configuration of the data collection system 100 according to the first embodiment of the present invention will be described with reference to FIG.

The data collection system 100 includes a target server 1 and a client terminal 2. The target server 1 is a server for which data is collected when a failure occurs. The client terminal 2 transmits various commands related to the data collection to the target server 1, and the target server 1 executes this command. The target server 1 and the client terminal 2 are communicably connected by a wired or wireless communication line.

Here, the target server 1 and the client terminal 2 are computers each having at least a storage device (not shown) for storing the program and a central control device for reading and executing the program from the storage device. Details will be described later.

(Target server)
As shown in FIG. 1, the target server 1 includes a control unit 11, a reference information storage unit 12, a collection unit 13, an execution unit 14, and a data storage unit 15.

The material storage unit 15 stores materials to be acquired when a failure occurs, when a material is updated, or the like. The materials are typically log information such as event logs and error logs of the target server 1, and various data that contribute to investigation of the operating status and failure details of the target server 1. In addition, the material may be any data collected for various purposes other than research purposes.

The reference information storage unit 12 stores reference information including material information related to materials and business information related to business applications executed by the target server. The reference information includes, for example, material information 12a (see FIG. 2), business information 12b (see FIG. 3), and a threshold value for determining whether to stop or suppress a business application. The threshold value may include the allowable hardware load.

The material information 12a is information in which each material is associated with the CPU usage rate. A threshold value for determining the stop or suppression of the business application may be added to this information, or a flag (symbol) indicating the stop or suppression of the business application may be added.

The business information 12b is a set of information related to each business. For example, as shown in FIG. 3, "business ID (IDentifier)", "business priority", "minimum guaranteed CPU usage rate", and "1 hour" A record whose item is "average CPU usage rate" is provided. The "business ID" is an identifier that can uniquely identify each business application. The "business priority" is information indicating the priority of the business application. The "minimum guaranteed CPU usage rate" is the minimum CPU usage rate required to execute a certain business application. The "average CPU usage rate per hour" is the usage rate of the CPU used on average per hour when executing a certain business application.

The control unit 11 acquires the reference information and the business application operating status of the target server, and determines whether or not the process for collecting data can be executed and the shortest start timing of the process based on the standard information and the business application operating status.

Further, when the business application is in operation, the control unit 11 determines whether or not to cancel the business application based on the priority included in the reference information. Further, when the business application is running, the control unit 11 determines that the hardware load required for the data collection process included in the reference information is equal to or less than the hardware allowable load (idle usage amount) of the target server 1. It is determined to stop the business application and execute the data collection process. Further, the control unit 11 is at least one running when the business application is running and the hardware load required for the data collection process included in the reference information is equal to or less than the allowable hardware load of the target server 1. When the business application is stopped and the allowable hardware load (idle usage) is increased, and as a result of the increase, the hardware load required for data collection processing becomes less than or equal to the allowable hardware load of the target server 1. Decide to stop the application and execute the data collection process.

Specifically, the control unit 11 determines whether or not the business can be canceled, whether or not the business can be suppressed, and whether or not the business can be canceled or suppressed based on the reference information, and executes data collection.

Whether or not the business can be canceled means whether or not the business performed by the target server 1 is a material that may be temporarily suspended for collecting data. Conversely, you may specify materials that should not be discontinued.

Whether or not the business can be suppressed means whether or not the business performed by the target server 1 can be suppressed for a certain period of time in order to collect the data. Conversely, you may specify materials that should not restrain your business. Here, suppression means, for example, reducing the usage rate of hardware resources required to execute a certain business application.

The business application capable of suspending or suppressing the business means whether the business application executed by the target server 1 may be temporarily suspended or suppressed in order to collect data. Conversely, business applications that cannot be stopped or suppressed may be specified.

The reference information is associated with each business or each material and is stored in the reference information storage unit 12 in advance. When setting the reference information, for example, the client is made to determine the reference information of all the materials in advance via the instruction unit 21 of the client terminal 2. Alternatively, the initial value is set in advance in the reference information storage unit 12 according to the instruction from the terminal on the design engineer or maintenance staff side, and the client transmits the reference information via the instruction unit 21 of the client terminal 2 as necessary. It may be configured to be adjustable.

When it becomes necessary to collect data, the client or the like transmits a request for collecting data to the control unit 11 via the instruction unit 21 of the client terminal 2.

Upon receiving the request for collecting data, the control unit 11 determines whether or not the business can be stopped. Specifically, the control unit 11 refers to the amount of idle resources (average CPU usage rate for one hour in FIG. 3) in the business information 12b. If the CPU usage rate of the material to be collected is equal to or less than the idle (unused) resource amount, the control unit 11 determines that the material can be collected without stopping the business, and immediately collects the material. For example, according to the business information 12b shown in FIG. 3, the idle is 5%. Therefore, the control unit 11 determines that the material (that is, the material a and the material c) having a CPU usage rate of 5% or less in the material information 12a shown in FIG. 2 can be collected without stopping the business.

Consider the case where the CPU usage rate of the collected data is larger than the idle resource amount (business suspension is required). A client or the like instructs the control unit 11 to collect the material b in FIG. 2 via the instruction unit 21 of the client terminal 2. The control unit 11 compares the CPU usage rate of the document b in FIG. 2 with the average CPU usage rate of the business ID “idle” in the business information 12b of FIG. 3 for one hour. In this case, the average CPU usage rate (5%) for one hour of idle is larger than the CPU usage rate (10%) in document b. Therefore, the control unit 11 determines that it is necessary to cancel the business, and checks the business priority for each business included in the business information 12b. As a result of the check, the control unit 11 stops the execution in order from the lowest priority work, and secures the CPU resource required for collection. For example, since the business D in the business information 12b has a business priority of "low" and an average CPU usage rate of "15%" for one hour, the use of the business D is stopped and data collection is executed.

Since the average CPU usage rate for one hour of business D is "15%" and the CPU usage rate required for collecting document b is 10% -5% (idle) = 5%, business D is performed. By suppressing the use of hardware resources without stopping, it is possible to obtain the CPU usage rate required for collecting the document b. In this case, the control unit 11 suppresses the average CPU usage rate for one hour of the business D by about 5%, and secures 10% of free CPU resources. After securing the CPU resource, the control unit 11 instructs the collection unit 13 to collect the material b from the material storage unit 15.

If the business priority in the business information 12b is the same, for example, if there are multiple business with the business priority "low", first compare the values of the minimum guaranteed CPU usage rate, and start with the one with the smallest value. To suppress the CPU usage rate. That is, if the CPU resources required for collection can be secured by the first suppression, data collection is executed, and if the CPU resources required for collection are still insufficient, the CPU with the next smallest guaranteed CPU usage rate. Suppress the usage rate (average CPU usage rate for 1 hour). In this way, when the necessary CPU resources are secured, the control unit 11 executes data collection.

Next, the determination of whether or not the business application can be suppressed will be described. As a preliminary preparation, the control unit 11 uses the control unit 11 as reference information for tasks that it does not want to suppress, and for tasks that may suppress the minimum guaranteed CPU utilization rate that is larger than the actually required CPU utilization rate. , The minimum guaranteed CPU usage rate, which is smaller than the actually required CPU usage rate, is set in advance. The control unit 11 determines that the business D (business ID = D) in the business information 12b shown in FIG. 3 can suppress the business because the minimum guaranteed CPU usage rate is 0%. The control unit 11 determines that the business B (business ID = B) cannot suppress the business because the minimum guaranteed CPU usage rate is 40%. A predetermined threshold value is set in advance for the minimum guaranteed CPU usage rate, and the control unit 11 cannot suppress business if the minimum guaranteed CPU usage rate is equal to or higher than the threshold value, and business if the minimum guaranteed CPU usage rate is lower than that. It may be judged that the suppression of the CPU is possible. Alternatively, the control unit 11 may determine whether or not the business can be suppressed according to the business priority (for example, if the business priority is "high", the business cannot be suppressed, and if the business priority is other than that, the business can be suppressed. Possible). It should be noted that not only the suppression of the business but also the suspension of the business may be similarly set with a predetermined threshold value, and the control unit 11 may determine whether or not the business should be canceled depending on whether or not the threshold value is exceeded.

If you want to perform more strictly "do not suppress" the business, the item of whether performance can be suppressed (for example, "can be suppressed", "cannot be suppressed") in the business priority in the business information 12b, and each business application. Add an item indicating the operating status of (for example, "operating", "not operating"). As a result, when the performance suppression is "uncontrollable" and the operating state is "operating", the control unit 11 is set not to suppress the business application.

The control unit 11 refers to the business priority in the business information 12b when determining whether or not the business application can be stopped or suppressed, and the business application having a high business priority is for collecting data. It may be determined that business should not be suspended or restrained.

A means for suppressing the performance of each business from the outside is prepared as an API (application programming interface). For example, the following APIs can be considered.
(B) Pausing function of running business application It has a function to pause the running business application.
(B) Executing business application restart function It has a function to resume the above-mentioned running business application when it is paused.
(C) Execution business application suppression function Various targets can be considered for suppression, but other indicators such as CPU usage rate, memory usage, disk transfer bandwidth, and network bandwidth may be used. And they may be combined. The index specified in the function may be suppressed by the function of the OS (operating system).
(D) Execution business application suppression release function The above-mentioned running business application suppression function has a function to restore and restart the business when suppression is performed.

(Client terminal)
The client terminal 2 includes an instruction unit 21.

The instruction unit 21 communicates with the control unit 11 of the target server 1 to perform a process of acquiring the current reference information, a process of instructing the setting or change of the reference information, and a process of instructing the execution or cancellation of the data collection process. conduct. In addition, the instruction unit 21 also performs a process of accepting the input of the above instruction by the user.

(Operation of data collection system)
The operation of the data collection system 100 according to the first embodiment of the present invention will be described.

The operation of the data collection system 100 is roughly divided into (1) an operation of setting or changing reference information in advance and (2) an operation of executing a data collection process based on the reference information. Furthermore, the operation of (2) is as follows: 1) operation of collecting or not collecting data according to whether or not business can be stopped, 2) operation of collecting or not collecting data according to whether or not business can be suppressed, and 3) operation of collecting or not collecting data according to business priority. It has an operation of collecting or not collecting data. Hereinafter, these functions will be described in order with reference to the flowchart. The operations 1), 2) and 3) of (2) may be executed in a predetermined order with a time lag, or all the operations may be executed in parallel.

(1) Operation for setting or changing reference information In the flowchart of FIG. 2, the instruction unit 21 and the control unit 11 communicate with each other to set or change the reference information in the reference information storage unit 12. Is shown.

First, in step S101, the instruction unit 21 of the client terminal 2 displays the current reference information to the user. Specifically, when the instruction unit 21 is activated in the client terminal 2, the instruction unit 21 acquires the current reference information and displays it on a display device (not shown) of the client terminal 2. If there are multiple reference information, the plurality of reference information can be displayed. The user can edit this reference information by an input / output device (not shown).

Here, as the current reference information, when the instruction unit 21 stores the reference information set or changed at the time of the previous execution of this function, the stored reference information can be acquired and displayed. Further, when the reference information set or changed last time is not stored, such as when the control unit 11 is started for the first time, the control unit 11 can be requested to transmit the current reference information, and the reference information received from the control unit 11 can be displayed. In the latter case, the control unit 11 can acquire all the current reference information from the reference information storage unit 12 and transmit it to the instruction unit 21 in response to the request from the instruction unit 21.

In step S102, the instruction unit 21 receives an input for setting or changing the current reference information via an input device on the user side (not shown). Here, the input device refers to a keyboard, a mouse, a button, a voice input, and the like.

For example, the instruction unit 21 can change the reference information according to the input by the user. The reference information is used to determine whether to execute or cancel the data collection process (details will be described later).

Further, the instruction unit 21 may be set so that materials displayed as a list or the like can be added, updated, or deleted in response to input by the user.

In step S103, the instruction unit 21 determines the setting or change of the reference information. Specifically, the instruction unit 21 determines the content of the setting or change in step S102 in response to a predetermined trigger, for example, pressing the "determine" button by the user. That is, the setting or change content of the reference information is passed to the process of S104.

In step S104, the instruction unit 21 transmits the reference information to the target server 1. Specifically, the instruction unit 21 transmits the setting or change content of the reference information determined in step S103 to the control unit 11 of the target server 1. Here, the instruction unit 21 may transmit only the set or changed reference information as the setting or change content of the reference information, or may transmit only the set or changed portion of the reference information. Alternatively, all standard information may be transmitted.

In step S105, the control unit 11 of the target server 1 receives the reference information. The above-mentioned reference information refers to the setting or change contents of the reference information.

In step S106, the control unit 11 registers the reference information. Specifically, the control unit 11 registers the setting or change content of the reference information received in step S105 in the reference information storage unit 12. As a result, the reference information held by the reference information storage unit 12 is updated.

(2) Operation to execute data collection processing based on standard information Below, referring to the flowcharts in FIGS. 5, 6 and 7, 1) Operation to collect or not collect data according to business priority, etc. 2) Business The operation of collecting or not collecting data according to the possibility of discontinuation and the operation of not collecting or collecting data according to the possibility of business restraint will be explained.

First, 1) the operation of collecting or not collecting materials according to the business priority and the like will be described with reference to the flowchart of FIG.

In step S201, when the control unit 11 receives a request from the client terminal 2 to collect one or more materials, the control unit 11 acquires the reference information (material information 12a and business information 12b) from the reference information storage unit 12. ..

In step S202, the control unit 11 determines whether or not there is a business application in operation. Specifically, the control unit 11 inquires of the execution unit 14 about the business application in operation. Alternatively, a flag may be set in the business information 12b as to whether or not each business application is in operation. If there is a running business application, the process proceeds to step S203, and if there is no running business application, the process proceeds to step S205.

In step S203, the control unit 11 confirms the business application in operation. Specifically, the ID and the like of the business application are acquired from the execution unit 14. Alternatively, the flag indicating whether or not each business application in the business information 12b is operating is referred to, and the operating business application is confirmed.

In step S204, the control unit 11 determines whether or not the operating business application may be stopped for collecting data. Specifically, if the business application being executed has a high priority (see FIG. 3), the control unit 11 determines that the business will not be stopped for collecting data, and has a priority other than that. If there is, it is judged that the business will be canceled due to the collection of data. If it is determined that the business will be suspended, the process will proceed to step S205, and if it is determined that the business will not be suspended, this process will end. When it is completed, the data collection waits until the running business application is completed.

In step S205, the control unit 11 instructs the collection unit 13 to collect the target material from the material storage unit 15. According to this instruction, the collection unit 13 collects the target material from the material storage unit 15 and hands it over to the control unit 11.

With the above, 1) the operation of collecting or not collecting data according to the business priority etc. is completed.

Next, 2) the operation of collecting or not collecting materials according to whether or not the business can be stopped will be described with reference to the flowchart of FIG.

First, steps S301 to S303 are the same as S201 to S203 in FIG. If it is determined in step S302 that there is no business application in operation, the process proceeds to the data collection process in step S311.

In step S304, the control unit 11 currently obtains the target material for the acquisition of the target material based on the one or more materials requested for collection and the reference information (material information 12a and business information 12b) acquired in step S301. Determine whether to stop the running business application. Specifically, the control unit 11 refers to the idle resource amount in the business information 12b (the average CPU usage rate for one hour in FIG. 3), and if the CPU usage rate of the collected material is equal to or less than the idle resource amount. , Judge that the data can be collected, and if it does not correspond to this, it is judged that the data cannot be collected. If it is determined that the data can be collected, the process proceeds to step S305, and if it is determined that the data cannot be collected, this process ends.

In step S305, the control unit 11 confirms the work to be canceled. For example, in the example of FIG. 2, it is confirmed that the material a and the material c are canceled.

In step S306, the control unit 11 instructs the execution unit 14 to stop the business application being executed. The execution unit 14 suspends the business according to the instruction.

In step S307, the control unit 11 instructs the collection unit 13 to confirm whether the material to be collected is in the material storage unit 15. The collecting unit 13 confirms that the materials (materials a and c) to be collected are stored in the material storage unit 15 in accordance with the instruction.

In step S308, the control unit 11 instructs the collection unit 13 to acquire the material from the material storage unit 15. The collection unit 13 acquires the material from the material storage unit 15 in accordance with the instruction.

In step S309, the control unit 11 confirms with the collection unit 13 whether all of the materials have been acquired from the material storage unit 15.

When it is confirmed that all of the materials have been acquired from the material storage unit 15, in step S310, the control unit 11 instructs the execution unit 14 to resume the suspended work. The execution unit 14 resumes the suspended business according to this instruction.

With the above, 2) the operation of collecting or not collecting data is completed according to whether or not the business can be stopped.

Finally, 3) the operation of collecting or not collecting data according to the possibility of business restraint will be described with reference to the flowchart of FIG. 7.

First, steps S401 to S403 are the same as S201 to S203 in FIG.

In step S404, the control unit 11 determines whether or not the work should be suppressed in order to acquire the target material based on the one or more materials requested for collection and the reference information acquired in step S401. do. Specifically, the control unit 11 compares the CPU usage rate of the material b in the material information 12a of FIG. 2 with the average CPU usage rate of the business ID “idle” in the business information 12b of FIG. 3 for one hour. In this case, since the average CPU usage rate (5%) for one hour of idle is larger than the CPU usage rate (10%) of the material b, the control unit 11 suppresses the work for acquiring the target material. Judge that it should be. If the average CPU usage rate for one hour of idle is smaller than the CPU usage rate of the material b, it is judged that it is not necessary to suppress the work in order to acquire the target material. If it is determined that the business should be restrained in order to acquire the target material, the process proceeds to step S405, and if it is determined that the business does not need to be suppressed in order to acquire the target material, the process is performed. The process proceeds to step S412, and the collection unit 13 acquires the target material from the material storage unit 15 and hands it over to the control unit 11.

In step S405, the control unit 11 compares the CPU usage rate of the target material (see FIG. 2) with the minimum guaranteed CPU usage rate of the target business (see FIG. 3), and confirms the load status. That is, the control unit 11 determines whether or not the CPU usage rate of the target material is larger than the minimum guaranteed CPU usage rate of the target business. If the CPU usage rate of the target material is larger than the minimum guaranteed CPU usage rate of the target business, it is judged that the load is small and vice versa.

If it is determined that the load is high, the process proceeds to step S407 in step S406. When it is determined that the load is low, in step S406, the process proceeds to step S412, and the data acquisition process is performed.

In step S407, the control unit 11 confirms whether the work may suppress the execution status. Specifically, the control unit 11 checks the business priority for each business included in the business information 12b, suppresses the CPU usage rate in order from the one with the lowest priority, and secures the CPU resources required for collection. For example, since the business D in the business information 12b has a business priority of "low" and an average CPU usage rate of "15%" for one hour, the CPU usage rate of the business D is suppressed by about 5%. As a result, it is confirmed that 10% of CPU resources can be secured by combining the idle (5%) and the 5% obtained as a result of suppressing the business D.

In step S408, the control unit 11 instructs the execution unit 14 to execute the process of securing the CPU resource described in step S407. The execution unit 14 suppresses the work according to this instruction.

In step S409, the control unit 11 confirms whether the work is actually suppressed and the CPU resource can be secured by suppressing the step S408.

After confirming that the CPU resource is secured in step S410, the control unit 11 instructs the collection unit 13 to collect the target material from the material storage unit 15. According to this instruction, the collection unit 13 collects the target material from the material storage unit 15 and hands it over to the control unit 11.

In step S411, the control unit 11 instructs the execution unit 14 to stop the process of securing the CPU resource described in step S407. According to this instruction, the execution unit 14 stops the suppression of securing resources and returns the business to the normal effective state. This ends 3) the operation of collecting or not collecting data according to the possibility of business restraint.
