Description

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

  In general, in order to collect various information related to the operating status of the server and details of failures, various data including log data such as event logs and error logs can be collected from the server by a monitoring client terminal. Has been done.

  For example, when a user specifies a server from which data is to be collected by manual operation, there is a technology that automatically collects predetermined data from a specified server, converts the collected data into a predetermined format, and automatically transmits it to a support center .

  Data collection is realized by a material collection program operating on the server performing material collection processing such as collection and transfer of materials 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 has been a problem that the user has to wait until the service provided by the server, for example, on weekends or late at night, and instruct the user to collect data at that time.

  In order to solve this problem, when collecting data is instructed by the user, the server from which failure information is collected (hereinafter also referred to as the target server) so that collecting the material does not hinder the stable operation of the server ) Is determined on the client terminal side, and a technique for measuring the collection timing is disclosed (see Patent Document 1).

JP 2014-059617 A

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

  The present invention has been made in view of the above problems, and a material collection system capable of shortening the waiting time until the material is collected without adversely affecting the processing of the entire system when collecting the material from the server. The purpose is to provide.

In order to solve the above problem, the material collection server according to the first aspect of the present invention provides:
A data collection server that controls the execution of processing to collect the data that it owns based on external instructions,

Collecting means for starting execution of the material collecting process according to the determination of the control means.

The material collection method according to the second aspect of the present invention is:
A data collection method for controlling the execution of a process of collecting data held by a data collection server based on an instruction from the outside,
From the reference information storage means for storing the reference information including the reference information including the information related to the data and the business application executed by the data collection server, to acquire the reference information, to acquire the business application operating status of the data collection server, Based on the reference information and the operational status of the business application, determine whether to execute the process and the shortest start timing of the process,
Starting execution of the process in accordance with the determination.

The problem estimation program according to the third aspect of the present invention is:

From the reference information storage means for storing the reference information including the reference information including the information related to the data and the business application executed by the data collection server, to acquire the reference information, to acquire the business application operating status of the data collection server, Based on the reference information and the operational status of the business application, determine whether to execute the process and the shortest start timing of the process,
Starting execution of the process in accordance with the determination. The program may be stored in a non-temporary recording medium.

  According to the present invention, it is possible to provide a data collection system or the like that can reduce the waiting time until data collection without adversely affecting the processing of the entire system when collecting data from a server.

It is a figure which shows the structure of the data collection server concerning 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.

  In the technique described in Patent Document 1, a technician who conducts a trouble investigation does not promptly submit materials including log information and trouble data necessary for trouble investigation from a customer or maintenance personnel in charge of the customer system. In some cases, it may take time to complete recovery from the failure. Collecting data is also called obtaining data. This was because maintenance personnel could not collect data while the customer system was running. That is, in the technique of Patent Document 1, data collection is automatically performed quickly as long as the conditions for collecting the data are met. There's a problem.

  Therefore, in each embodiment of the present invention, the immediacy of data collection (shortest start timing) or the waiting time reduction is pursued. Even if a business application (hereinafter also referred to as a business application) is running on the target server (customer server) of the customer system, it is a business application that can be paused, and the collection of data is short. If it is completed in the above, even if the operation of the business application is temporarily stopped, there is no big trouble in the entire customer system. Further, in the technique described in Patent Document 1, if the load on the server from which data is collected is high, the data collection cannot be executed immediately. However, depending on the priority of the business application (for example, when the priority is low), the load on the server from which data is collected can be reduced by temporarily restricting the allocation of hardware resources such as CPUs to the business application. You can deliberately lower it for a certain period of time and complete the data collection during that time. Note that, among business applications, when a business application with a high priority for which the operation is to be continued or a business application with the highest priority is operating, there is a case where data collection may not be executed. In such a case, data collection is waited until the business application stops operating.

  The above will be described in detail in three plans. First, the customer server side stops the work for a certain period of time and executes the material collection first. This is effective when it is determined that data collection is completed in a short time. As advance preparations, it is possible to have the client or customer system operator list the types of materials in advance, and if any of these listed materials is collected, the work may be suspended and the materials collected. Is set in advance. When it is actually necessary to collect data, if the setting allows the operation to be stopped for a certain period of time, the worker collects data from the target server. At this time, the target server (hereinafter also referred to as “target server A”) displays on the monitor of the client or the operator's terminal, etc., that the business is suspended for a certain period of time, and further stops the business for a certain time in this display. You may get permission again from the client. Note that the business application is automatically restarted after the collection of data is completed.

  The second method is to control (suppress) the hardware resources of the business application being executed so that the load on the customer system is not increased. That is, if the hardware load for executing the business application in the target server is high, the target server A intentionally reduces the load during the collection of the material, and collects the material in parallel with the execution of the business application. As advance preparation, a business application whose execution may be controlled is selected in advance by operation of a client or an operator. When it is actually necessary to collect data, the target server A determines whether or not the load of the operating business application is higher than the threshold value. If it is determined that the load is high, the target server A monitors the client or operator. Displays that business application execution is controlled. At the time of this display, the target server A may obtain permission from the client again to control 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. It should be noted that the hardware load of the business application is automatically returned to the base after the completion of data collection.

  The third method is to specify whether or not to collect data depending on which business application is being executed among the business applications running on the target server of the customer system. This is because the importance of work may differ from client to client. As described above, the target server A is designed so that it is possible to specify whether or not material collection can be executed after prioritizing each business application included in the business application according to the client. In other words, the target server A gives priority to each business application instead of judging the load status by focusing only on the hardware resources. Further, not only the business application of the customer, but other application software may be added as a reference for determining whether or not to collect data. As advance preparations, the client is allowed to designate in advance a business application that does not want to execute data collection. When a business application that must not collect data is in operation when data collection is required, the target server A waits for the business application to end without performing data collection, and other business tasks Collect data immediately during operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings schematically show the configuration in the embodiment of the present invention. Furthermore, the embodiment of the present invention described below is an example, and can be appropriately changed within a range in which the essence 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 material collection system 100 according to the first embodiment of the present invention will be described with reference to FIG.

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

  Here, each of the target server 1 and the client terminal 2 is a computer having at least a storage device (not shown) that stores a program and a central control device that reads and executes the program from the storage device. Details will be described later.

(Target server)
As illustrated 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 material storage unit 15.

  The material storage unit 15 stores materials that should be acquired when a failure occurs or when a material is updated. The material is typically log information such as an event log or an error log of the target server 1 and various data that contribute to the investigation of the operation status of the target server 1 or the contents of failure. The material may be any data collected for various purposes other than the survey purpose.

  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 the business application is stopped or suppressed. The threshold value may include a hardware allowable load.

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

  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", "1 hour A record having “average CPU usage rate” as an item is provided. The “business ID” is an identifier that can uniquely identify each business application. “Business priority” is information representing the priority of the business application. The “minimum guaranteed CPU usage rate” is the minimum CPU usage rate required for executing a certain business application. The “average CPU usage rate for one hour” is the usage rate of a CPU that is used on average per hour when a certain business application is executed.

  The control unit 11 acquires the reference information and the business application operating status of the target server, and determines whether or not to execute processing for collecting materials and the shortest start timing of the processing based on the reference information and the operating status of the business application.

  Further, when the business application is in operation, the control unit 11 determines whether to cancel the business application based on the priority included in the reference information. Furthermore, when the business application is in operation, the control unit 11 includes a hardware load necessary for the material collection process included in the reference information that is equal to or less than a hardware allowable load (idle usage amount) of the target server 1. It is determined that the business application is stopped and the material collection process is executed. Furthermore, the control unit 11 has at least one of the running applications when the business application is in operation and the hardware load required for the data collection process included in the reference information is equal to or less than the hardware allowable load of the target server 1. When a 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 falls below the allowable hardware load of the target server 1, the business Determine whether to stop the application and execute the data collection process.

  Specifically, based on the reference information, the control unit 11 determines whether or not the business can be stopped, whether or not the business can be suppressed, and whether the business application is capable of canceling or suppressing the business, and collects data.

  Whether or not the business can be canceled means whether or not the business that the target server 1 performs is a material for which the business may be temporarily stopped for collecting the data. Conversely, materials that should not be interrupted may be identified.

  Whether or not business suppression is possible means whether or not the business of the target server 1 is a material whose business may be suppressed for a certain period in order to collect data. Conversely, materials that should not be restricted may be identified. Here, suppression refers to, for example, lowering the usage rate of hardware resources necessary for executing a certain business application.

  The business application capable of canceling or suppressing the business means whether the business application executed by the target server 1 is a business application whose temporary execution may be stopped or suppressed for data collection. Conversely, business applications that cannot be stopped or suppressed may be specified.

  The reference information is stored in the reference information storage unit 12 in advance in association with each business or each material. In setting the reference information, for example, the reference information of all materials is determined in advance by the client via the instruction unit 21 of the client terminal 2. Alternatively, an initial value is set in the reference information storage unit 12 in advance by an instruction from the terminal on the design engineer / maintenance person side, and the client receives the reference information via the instruction unit 21 of the client terminal 2 as necessary. You may comprise so that adjustment is possible.

  When data collection is required, a client or the like transmits a data collection request to the control unit 11 via the instruction unit 21 of the client terminal 2.

  When the control unit 11 receives the material collection request, the control unit 11 determines whether or not the business can be stopped. Specifically, the control unit 11 refers to the idle resource amount (average CPU usage rate for one hour in FIG. 3) in the business information 12b. If the CPU usage rate of the collected material 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 operation, and collects the material immediately. For example, according to the business information 12b shown in FIG. Therefore, the control unit 11 determines that the materials whose CPU usage rate is 5% or less (that is, the materials a and c) in the material information 12a shown in FIG.

  Consider a case where the CPU usage rate of the collected material is a CPU usage rate larger than the idle resource amount (necessary to cancel the business). 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 material b in FIG. 2 with the average CPU usage rate for 1 hour of the business ID “idle” in the business information 12b of FIG. In this case, the average CPU usage rate (5%) for one hour of idle is larger than the CPU usage rate (10%) of the material 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 job with the lowest priority, and secures CPU resources necessary for collection. For example, since the business priority in the business information 12b is “low” and the average CPU usage rate for one hour is “15%”, the usage of the business D is stopped and the data collection is executed.

  In addition, since the average CPU usage rate for the hour of the job D is “15%” and the CPU usage rate necessary for collecting the material b is 10% −5% (idle) = 5%, Even without stopping, it is possible to obtain the CPU usage rate necessary for collecting the material b by suppressing the use of hardware resources. In this case, the control unit 11 suppresses the average CPU usage rate for one hour of the job 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.

  When the business priorities in the business information 12b are the same, for example, when there are a plurality of businesses with the business priority “low”, first, the values of the minimum guaranteed CPU usage rates are compared, and the value from the smallest is determined. Therefore, the CPU usage rate is suppressed. In other words, if CPU resources necessary for collection can be secured by the first suppression, data collection is performed. If CPU resources necessary for collection still run short, the CPU with the next lowest guaranteed CPU utilization value is the next smallest CPU The usage rate (average CPU usage rate for 1 hour) is suppressed. In this way, when necessary CPU resources can be secured, the control unit 11 executes material collection.

  Next, determination of whether or not business applications can be suppressed will be described. As a preliminary preparation, the control unit 11 uses, as reference information, for a business that may not be suppressed, for a business that may suppress a minimum guaranteed CPU usage rate that is larger than the CPU usage rate actually required. A minimum guaranteed CPU usage rate smaller than the actually required CPU usage rate is set in advance. The control unit 11 determines that the job D (job ID = D) in the job information 12b illustrated in FIG. 3 can be suppressed because the minimum guaranteed CPU usage rate is 0%. Since the minimum guaranteed CPU usage rate is 40% for the business B (business ID = B), the control unit 11 determines that the business cannot be suppressed. A predetermined threshold value is set in advance in the minimum guaranteed CPU usage rate, and the control unit 11 cannot suppress the business if the minimum guaranteed CPU usage rate is equal to or higher than the threshold value, and if the minimum guaranteed CPU usage rate is less than that, the control unit 11 You may judge that suppression of this 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 control is not possible, and if the business priority is other than that, the control unit 11 suppresses the business. Possible). It should be noted that a predetermined threshold value may be similarly set not only in the suppression of the business but also in the suspension of the business, and the control unit 11 may determine whether or not to cancel depending on whether or not the threshold is exceeded.

  When it is desired to more strictly execute “do not suppress” the business, the business priority in the business information 12b indicates whether or not the performance can be suppressed (for example, “suppressable”, “cannot be suppressed”), and each business application An item indicating the operating state (for example, “operating”, “not operating”) is added. As a result, when the performance suppression is “cannot be suppressed” and the operation state is “in operation”, 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 the business application is capable of canceling or suppressing the business, and the business application with a high business priority is used for collecting data. You may decide that you should not suspend or control your work.

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.
(A) A function for temporarily suspending a business application being executed while the business application currently executing function is suspended.
(B) A running business application resume function has a function to resume when the running business application is paused.
(C) In-execution business application suppression function Various targets can be considered here, but other indices such as CPU usage rate, memory usage, disk transfer bandwidth, network bandwidth, etc. may be used. They may be combined. The index specified in the function may be suppressed by the function of the OS (operating system).
(D) In-execution business application suppression release function In the above-described in-execution business application suppression function, when suppression is performed, it has a function of returning the business to its original state and restarting it.

(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 processing for obtaining current reference information, processing for instructing setting or changing of reference information, and processing for instructing execution or cancellation of the material collection processing. Do. The instruction unit 21 also performs a process of accepting an input of the instruction by the user.

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

  The operation of the material collection system 100 is roughly divided into (1) an operation for setting or changing reference information in advance and (2) an operation for executing a material collection process based on the reference information. In addition, the operation of (2) is 1) the operation that does not collect or collect data according to whether or not the business is canceled, 2) the operation that does not collect or collect data according to whether or not the business is suppressed, and 3) according to the business priority. It has an operation to collect or not collect data. Hereinafter, these functions will be described in order with reference to flowcharts. Note that the operations (1), (2), and (3) in (2) may be executed in time order according to a predetermined order, 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 to change the reference information for which reference information is set or set 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. When there are a plurality of pieces of reference information, the pieces of reference information can be displayed. The user can edit the reference information using an input / output device (not shown).

  Here, when the instructing unit 21 stores the reference information that has been set or changed at the time of the previous execution of the present function, the current reference information can be acquired and displayed. In addition, when the reference information that has been set or changed last time is not stored, such as at the first activation, 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 current reference information from the reference information storage unit 12 and transmit it to the instruction unit 21 in response to a 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 a user-side input device (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 in response to an 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).

  Moreover, the instruction | indication part 21 may be set so that the data displayed as a list etc. can be added, updated, and deleted according to the input by a user.

  In step S103, the instruction unit 21 determines setting or changing of the reference information. Specifically, the instructing unit 21 confirms the content of the setting or change in step S102 in response to a predetermined trigger, for example, pressing of the “decision” button by the user. That is, the setting or changing content of the reference information is transferred to the process of S104.

  In step S <b> 104, the instruction unit 21 transmits reference information to the target server 1. Specifically, the instruction unit 21 transmits the setting or change contents of the reference information determined in step S <b> 103 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 reference information setting or change content, or may transmit only the set or changed portion of the reference information. Alternatively, all reference information may be transmitted.

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

  In step S106, the control unit 11 registers 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 for executing material collection processing based on reference information Referring to the flowcharts of FIGS. 5, 6, and 7 below, 1) operation for not collecting or collecting materials according to business priority, etc., 2) business The operation that does not collect or collect data according to whether or not cancellation is possible, and 3) the operation that does not collect or collect data according to whether or not business suppression is possible will be described.

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

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

  In step S202, the control unit 11 determines whether there is an active business application. Specifically, the control unit 11 inquires of the execution unit 14 about a running business application. Alternatively, a flag indicating whether each business application is in operation may be set in the business information 12b. If there is an active business application, the process proceeds to step S203. If there is no active business application, the process proceeds to step S205.

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

  In step S <b> 204, the control unit 11 determines whether the operating business application can be canceled for collecting data. Specifically, when the business application being executed has the priority “high” (see FIG. 3), the control unit 11 determines that the business is not stopped for collecting data, and uses other priorities. In some cases, it is determined that the work will be suspended for collecting data. If it is determined that business suspension is to be performed, the process proceeds to step S205. If it is determined that business suspension is not to be performed, this processing ends. When the process is completed, the data collection is on standby until the business application being executed is completed.

  In step S <b> 205, the control unit 11 instructs the collection unit 13 to collect the target material from the material storage unit 15. In accordance with this instruction, the collection unit 13 collects the target material from the material storage unit 15 and delivers it to the control unit 11.

  1) End the operation that does not collect or collect data according to business priority.

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

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

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

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

  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 task according to the instruction.

  In step S <b> 307, the control unit 11 instructs the collection unit 13 to confirm whether the material to be collected exists in the material storage unit 15. The collection unit 13 confirms that the materials to be collected (the material a and the material c) are stored in the material storage unit 15 according to the instruction.

  In step S <b> 308, 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 according to the instruction.

  In step S <b> 309, the control unit 11 confirms with the collection unit 13 whether all of the material has 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 temporarily suspended work. The execution unit 14 resumes the suspended work in accordance with this instruction.

  2) End the operation that does not collect or collect data according to whether or not the work can be stopped.

  Finally, 3) the operation of collecting or not collecting data according to whether or not the work can be suppressed will be described with reference to the flowchart of FIG.

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

  In step S404, the control unit 11 determines whether or not to suppress the business for acquiring the target material based on the one or more materials requested for collection acquired in step S401 and the reference information. To do. Specifically, the control unit 11 compares the CPU usage rate of the material b in the material information 12a in FIG. 2 with the average CPU usage rate for 1 hour of the business ID “idle” in the business information 12b in FIG. 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 work for obtaining the target material. Judge that it should. Note that if the average CPU usage rate for one hour of idle is smaller than the CPU usage rate of the material b, it is determined that it is not necessary to suppress work for obtaining the target material. If it is determined that the work should be suppressed for the acquisition of the target material, the process proceeds to step S405. If it is determined that the business need not be suppressed for the acquisition of the target material, the process is performed. In step S412, the collection unit 13 acquires the target material from the material storage unit 15 and delivers it 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) to confirm the load status. That is, the control unit 11 determines whether the CPU usage rate of the target material is larger than the minimum guaranteed CPU usage rate of the target business. When the CPU usage rate of the target material is larger than the minimum guaranteed CPU usage rate of the target business, it is determined 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 a material acquisition process is performed.

  In step S <b> 407, the control unit 11 confirms whether or not the execution status may be suppressed. Specifically, the control unit 11 checks the business priority for each business included in the business information 12b, suppresses the CPU usage rate in descending order of priority, and secures CPU resources necessary for collection. For example, since the business priority in the business information 12b is “low” and the average CPU usage rate for one hour is “15%”, 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 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 for securing the CPU resource described in step S407. The execution unit 14 suppresses work according to this instruction.

  In step S409, the control unit 11 confirms whether or not business is actually suppressed and CPU resources can be secured by the suppression of step S408.

  In step S410, after confirming the reservation of the CPU resource, the control unit 11 instructs the collection unit 13 to collect the target material from the material storage unit 15. In accordance with this instruction, the collection unit 13 collects the target material from the material storage unit 15 and delivers it 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. In accordance with this instruction, the execution unit 14 stops the suppression of the resource reservation and returns the operation to the normal effective state. Thus, 3) the operation of collecting or not collecting the data is terminated according to whether or not the work is suppressed.
