Description

  The present invention relates to an information processing apparatus and a program.

  In recent years, applications that can add functions flexibly have been developed by adopting a software expansion mechanism called add-in. Such an application is expanded in function by an executable program called a platform that reads an add-in DLL (Dynamic Link Library) program provided by a third party. These programs usually operate in one process on the computer. Therefore, resource information (for example, CPU usage rate and memory usage) used by the above program is acquired in one process unit.

  Patent Document 1 discloses a program analysis technique that can grasp the name of a function that was operating when the CPU load is high.

  On the other hand, provided by Microsoft (registered trademark). The NET Framework (registered trademark) provides an application domain that is a safer and more flexible processing unit that can be used to separate resources used between programs. Each application domain can be loaded in one process, for example (Non-Patent Document 1).

1. 1. System overview 2. Hardware configuration Functional configuration Operation Example In this specification, the word “program” is used as a concept including an application or a library.

≪ １． System overview ≫
FIG. 1 is a diagram showing an overview of a system according to an embodiment of the present invention. The system includes an information processing device 1 and one or more monitoring devices 2a and 2b (hereinafter collectively referred to as monitoring device 2). The information processing apparatus 1 is, for example, a computer installed in an industrial plant and provided by Microsoft Corporation. It has a NET Framework execution environment (runtime).

  A program (application) called a platform is installed in the information processing apparatus 1. The platform centrally collects information useful for plant managers, such as information sent from the monitoring device 2 connected via the network in the plant, calendar information, and information on the list of equipment in the plant. It is an application to display. These pieces of information are provided by a DLL (add-in) program (library) developed for the platform.

  FIG. 2 shows an example of a screen displayed by the platform. As shown in FIG. 2, a display area for a plurality of add-ins is included inside a window of a platform (herein, named “multi-platform”). Each add-in can display various information using these display areas.

  Further, the platform can acquire and output information on resources to be used (hereinafter referred to as “resource information”) for each add-in. The resource information includes, for example, a CPU usage rate per second and a memory usage amount (instantaneous value). The platform displays the add-in management screen illustrated in FIG. 3 when there is an instruction from the administrator or the like or when a predetermined condition is satisfied, and displays a list of resource information used by the add-in. For example, when the system load of the information processing apparatus 1 is abnormally high, the administrator or the like can check whether the add-in is the cause.

  The platform obtains resource information for each add-in in DLL format. Use the application domain function of NET Framework. An application domain is a unit for managing resources such as a CPU and a memory, and operates within one process. The platform operates each add-in in a different application domain for each add-in. The platform can obtain resource information for each add-in by acquiring resource information of each application domain and regarding the resource information as resource information of the add-in.

  FIG. 4 shows a configuration example of the application domain of the platform and the add-in. The platform executable file 10 loads add-in A11 and add-in B12 which are DLLs for function expansion. Here, FIG. 4 also shows a library A13 (non-add-in) loaded by the platform 10 and a library B14 (non-add-in) loaded by the add-in B12. The platform 10 (and library A13) operates in the application domain A15. On the other hand, the add-in A11 operates in an application domain B16 that is different from the platform application domain A15. Further, the add-in B12 (and the library B14) operates in an application domain C17 that is different from the application domains A and B of the platform and the add-in A11.

  As described above, the information processing apparatus 1 according to an embodiment of the present invention can grasp the resource usage status of a DLL-type add-in that operates on an application serving as a platform. As a result, when the load on the information processing apparatus 1 is abnormally high, it is possible to determine what add-in is the cause.

  The information processing apparatus 1 is not limited to an example of a computer installed in a plant, and may be an arbitrary computer installed in an arbitrary place.

≪ 2. Hardware configuration ≫

An information processing apparatus 1 illustrated in FIG. 1 includes a CPU 21, a ROM 22, a RAM 23, an HDD (Hard Disk Drive) / SSD (Solid State Drive) 24, a NIC (Network Interface Card) 25, a display 26, A keyboard 27, a mouse 28, and a bus 29 are provided.

  The CPU 21 executes an OS and a system program that perform operation control of the information processing apparatus 1 and an application such as a platform. The ROM 22 stores a system program executed by the CPU 21 and the like. The RAM 23 constitutes a work area for the CPU 21. The HDD / SSD 24 stores programs and libraries such as platforms and add-ins, data received from the monitoring device 2, and the like. The NIC 25 includes a wired communication interface and its control device, and is used to communicate with an external device. The display 26 includes a liquid crystal display and a graphics controller, and presents information to the user. The keyboard 27 and mouse 28 accept input from an administrator or the like. The bus 29 connects the above-described devices constituting the information processing apparatus 1 to each other and exchanges data.

  The add-in storage unit 51 is realized by the HDD / SSD 24 and stores an add-in program provided in the DLL format.

  The registration unit 52 is realized mainly by the processing of the CPU 21, reads the add-in stored in the add-in storage unit 51, and defines a different application domain for each add-in. Each add-in is registered in the defined application domain. The registration unit 52 registers the platform in an application domain different from the add-in application domain. Note that each add-in and platform application domain defined in this way operates in one process.

  The control unit 53 is realized mainly by the processing of the CPU 21. It is a runtime of NET Framework. . The NET Framework manages resources such as a CPU and a memory for each application domain. Also,. The NET Framework provides resource information used in the application domain through properties of a class (AppDomain) that defines the application domain.

The condition storage unit 54 is realized by the HDD / SSD 24 and stores resource information acquisition conditions or output conditions for each add-in. Examples of specific conditions are as follows.

  The acquisition unit 55 is realized mainly by the processing of the CPU 21, and acquires the resource information used by the application domain registered by the registration unit 52 according to the condition (1) stored in the condition storage unit 54. That is, the acquisition unit 55 acquires the resource information of the application domain corresponding to the add-in that is the “resource information acquisition target” in the condition storage unit 54.

  Here, the resource information is, for example, a CPU usage rate (%) or memory usage (bytes; instantaneous value) per second. CPU usage per second is. It can be calculated based on the CPU time used by the application domain, which is obtained by a function provided by the NET Framework (for example, the MonitoringTotalProcessorTime property of the AppDomain class). A specific calculation method will be described later. Similarly, the memory usage (instantaneous value) is also. It can be acquired by a function provided by the NET Framework (for example, the MonitoringSurvivedMemorySize property of the AppDomain class).

  The acquisition unit 55 acquires resource information of one process in which the platform and the application domain of the add-in operate. The process resource information is: It can be acquired by the function of the NET Framework (for example, the TotalProcessorTime property of the Process class and the MonitoringSurvivedProcessMemorySize property of the AppDomain class).

  Hereinafter, the above-described two types of resource information (resource information of each application domain and process resource information) will be described separately.

  The threshold storage unit 56 is realized by the HDD / SSD 24 and stores a threshold for resource information of the application domain and a threshold for resource information of the process. As described above, the resource information is, for example, a CPU usage rate or a memory usage amount per second. Each threshold value is set in advance by the administrator of the information processing apparatus 1. The threshold is set according to the number of application domains (that is, the number of add-ins).

  The comparison unit 57 is realized mainly by the processing of the CPU 21, and compares the value (CPU usage rate or memory usage amount) indicated by the resource information acquired by the acquisition unit 55 with the threshold value stored in the threshold value storage unit 56. When the resource information is equal to or greater than the threshold value, the output control unit 58 is notified accordingly.

  The output control unit 58 is realized mainly by the processing of the CPU 21, and controls so that the resource information of the application domain acquired by the acquisition unit 55 is output according to the conditions (2) and (3) stored in the condition storage unit 54. To do. That is, among the resource information acquired by the acquisition unit 55, the output control unit 58 indicates that the resource information of the add-in that is “target of resource information output” by the condition storage unit 54 is “resource information output cycle”. The output unit 59 is controlled so as to be output.

  Further, in response to the notification from the comparison unit 57, the output control unit 58 outputs the resource information of the application domain only when the value indicated by the acquired resource information of the application domain is greater than or equal to the threshold value. The output unit 59 may be instructed.

  Further, the output control unit 58 outputs the resource information of each application domain in response to the notification from the comparison unit 57 only when the value indicated by the acquired resource information of the process is greater than or equal to the threshold value. The unit 59 may be instructed.

  Further, the output control unit 58 causes the output unit 59 to output information received from the monitoring device 2 via the network.

  The output unit 59 is realized mainly by the processing of the CPU 21, and outputs the resource information of the application domain as the resource information of the corresponding add-in based on an instruction from the output control unit 58. The output unit 59 displays the resource information on the display 26 of the information processing apparatus 1. Further, the output unit 59 may transmit the resource information to another information processing apparatus via the communication unit 61.

  The output unit 59 outputs information received from the monitoring device 2 via the network to the display unit 60.

  The display unit 60 is realized mainly by the display 26 and displays add-in resource information output from the output unit 59 and information received from the monitoring device 2.

  The communication unit 61 is realized mainly by the NIC 25, and transmits the add-in resource information output from the output unit 59 to another information processing apparatus.

  With the above function, the information processing apparatus 1 according to an embodiment of the present invention can acquire resource information used by each add-in by operating a DLL-format add-in in an individual application domain. In addition, when the resource being used exceeds a predetermined amount, the information on the resource is displayed so that the administrator can determine which add-in is consuming the resource as necessary. Can be identified.

<< 4. Example of operation ≫
Next, a processing flow of the information processing apparatus 1 according to the embodiment of the present invention will be described with reference to FIGS. A part of the source code for realizing the processing is illustrated in FIGS. FIG. 7 illustrates a process of outputting all resource information of the add-in that is the output target, FIG. 8 illustrates a process that uses the threshold value of the resource information of the add-in that is the acquisition target, and FIG. 9 illustrates the threshold value of the resource information of the process Represents a process using. Hereinafter, it demonstrates in order. In the following description, the resource information is a CPU usage rate or a memory usage amount per second.

≪Example of outputting all resource information≫
FIG. 7 illustrates a process in which the information processing apparatus 1 according to the embodiment of the present invention outputs all resource information of an add-in that is an output target. The processing may be repeatedly executed at regular intervals, or may be executed irregularly according to some event.

  In step 100, the registration unit 52 reads the DLL format add-in stored in advance in the add-in storage unit 51, and creates an application domain for each add-in. FIG. 10 shows source code for the registration unit 52 to read in the add-in. Mainly from the sixth line to the thirteenth line in FIG. 11, the registration unit 52 creates source code for creating an application domain. .

  In step 101, the registration unit 52 registers each add-in in each application domain created in step 100. The 15th line in FIG. 11 is source code for the registration unit 52 to register the add-in in the application domain.

  In step 102, the acquisition unit 55 and the output control unit 58 read the conditions stored in the condition storage unit 54, respectively. The conditions are defined in advance for each add-in, whether the resource information is acquired by the acquisition unit 55, whether the resource information is output by the output control unit 58, or whether the resource information is output by the output control unit 58 The cycle for outputting is determined.

  In step 103, the acquisition unit 55 acquires the CPU usage rate and the memory usage amount of the add-in that is the acquisition target in accordance with the conditions read in step 102. Here, the acquisition unit 55 cannot directly acquire the CPU usage rate of each application domain from the control unit 53. Therefore, the acquisition unit 55 acquires the total CPU time used by each application domain from the control unit 53. The fifth line in FIG. 12 represents source code for obtaining the memory usage of the application domain, and the ninth line in FIG. 12 represents source code for obtaining the CPU time used by the application domain. .

  In step 104, the acquisition unit 55 calculates the CPU usage rate per unit time (1 second) from the CPU time acquired in step 103. The 10th to 18th lines in FIG. 12 are source codes for calculating the CPU usage rate per second using the CPU time and the time acquired last time and the information of the CPU time and current time acquired this time. Represents.

  In step 105, the output control unit 58 uses the CPU usage rate and memory usage acquired in steps 103 and 104 for the add-in to be output according to the conditions read in step 102, and the CPU usage rate of the add-in. And output as memory usage.

  Thereafter, the display unit 60 displays the screen as shown in FIG. The screen includes a list of add-ins, a CPU usage rate and a memory usage amount of each add-in.

  As described above, the CPU usage rate and the memory usage amount used by the add-in provided in the DLL format can be easily grasped.

≪Example using threshold value≫
FIG. 8 illustrates a process in which the information processing apparatus 1 according to the embodiment of the present invention outputs add-in resource information using a threshold value. The processing may be repeatedly executed at regular intervals, or may be executed irregularly according to some event.

  Steps 200 to 204 are the same as steps 100 to 104 in FIG.

  In step 205, the comparison unit 57 reads the threshold value for the resource information of the application domain stored in the threshold value storage unit 56. Here, the CPU usage rate threshold and the memory usage threshold of the application are read.

  In step 206, the comparison unit 57 compares the CPU usage rate and memory usage acquired in steps 203 and 204 with the threshold value read in step 205, respectively.

  In step 207, the output control unit 58 causes the output unit 59 to output add-in information corresponding to the application domain indicating the CPU usage rate and the memory usage amount that are equal to or higher than the threshold among the add-ins to be output.

  As described above, it is possible to easily identify an add-in in which the CPU usage rate and / or the memory usage amount exceeds a preset threshold value. Further, the load on output and display is reduced as compared with the case of outputting all add-in information.

≪ Example using process threshold ≫
FIG. 9 shows a process in which the information processing apparatus 1 according to the embodiment of the present invention outputs add-in resource information using the process resource information. The processing may be repeatedly executed at regular intervals, or may be executed irregularly according to some event.

  Steps 300 to 304 are the same as steps 100 to 104 in FIG. 7 or steps 200 to 204 in FIG.

  In step 305, the acquisition unit 55 acquires the CPU usage rate and the memory usage amount of the process in which the entire application domain of the platform and the add-in operates.

  In step 306, the comparison unit 57 reads the threshold value for the resource information of the process stored in the threshold value storage unit 56. Here, the CPU usage rate threshold and the memory usage threshold of the process are read.

  In step 307, the comparison unit 57 compares the CPU usage rate and memory usage acquired in step 305 with the threshold value read in step 306.

  In step 308, if either or both of the CPU usage rate and the memory usage amount of the process are equal to or larger than the threshold value, the process proceeds to step 309. Otherwise, the process ends.

  In step 309, the output control unit 58 causes the output unit 59 to output information on the add-in that is the output target.

  As described above, the CPU usage rate and the memory usage amount of each add-in can be output when the CPU usage rate and / or the memory usage amount of the entire process in which the platform operates exceed a preset threshold. As a result, when the platform shows a high load, the administrator can easily identify the add-in that causes the load.

  Note that the threshold for the resource information of the application domain described using FIG. 8 and the threshold for the resource information of the process described using FIG. 9 may be used in combination.
