Conventionally, the system health check is to check all processes using a unique check method provided by each process in order to confirm that all of a plurality of process groups are operating normally. It was. For example, in Japanese Patent Application Laid-Open No. 10-116211, a dedicated health check process periodically sends health check data to each process, checks each response time, and determines whether there is an error.
[0003]
[Problems to be solved by the invention]
However, in order to individually confirm that all processes are operating normally as described above, knowledge about all processes is required. In addition, since the checking method for each process is not unified, it is necessary to check using a method corresponding to each process, so that it is difficult to execute automatically. In particular, when the number of processes is large, there is a problem that it may take an enormous amount of time to check all processes.

In order to solve the above problems, the present invention may be a method executed by the system health check program, an apparatus for executing the system health check program, and a recording medium on which the system health check program is recorded.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is a diagram illustrating a hardware configuration example of a system health check apparatus according to an embodiment of the present invention. The system health check device 10 in FIG. 1 includes a drive device 100, a storage medium 101, an auxiliary storage device 102, a memory device 103, an arithmetic processing device 104, and an interface device 105, which are mutually connected by a bus B. And is configured to have.
[0010]
The interface device 105 includes, for example, a modem, a router, etc., and is used to connect to the network 40 in FIG.
[0011]
A system health check program used by the system health check apparatus 10 is provided by a storage medium 101 such as a CD-ROM. The storage medium 101 on which the system health check program is recorded is set in the drive device 100, and the system health check program is installed from the storage medium 101 to the auxiliary storage device 102 via the drive device 100.
[0012]
The auxiliary storage device 102 stores the installed system health check program and also stores necessary files and data. For example, the auxiliary storage device 102 stores various tables, which will be described later, necessary for processing the system health check program.
[0013]
The memory device 103 reads the system health check program from the auxiliary storage device 102 and stores it when there is an instruction to start the system health check program, such as when the system health check device 10 is started. The arithmetic processing unit 104 executes functions related to the system health check device 10 according to the system health check program stored in the memory device 103.
[0014]
Next, an event management system that monitors the operation of the system health check apparatus 10, that is, the system health check program in the present embodiment will be described. FIG. 2 shows a configuration diagram of an example of an event management system monitored by the system health check program according to the present invention.
[0015]
The event management system 30 in FIG. 2 includes a start process 31, an intermediate process 32, an end process 33, a host management DB 34, an event management DB 35, and the like, and is installed in a predetermined host 20. The host 20 is connected to a host A, a host B, a host C, a host D, and the like via a network 40 such as a LAN.
[0016]
The event management system 30 is a system for processing event data such as failure information transmitted from the host A 41 or the like. That is, when the host 20 receives event data from the host A 41 or the like (S 1), the originating process 31 determines whether or not the host A 41 that sent the event data has already been registered in the host management DB 34 and has not been registered. In this case, the information of the host A41 is registered in the host management DB 34 (S2). Proceeding to step S3 following step S2, the origin process 31 transmits the event data to the intermediate process 32.
[0017]
When receiving the event data, the intermediate process 32 executes predetermined processing on the event data and transmits the event data to the end point process 33 (S4).
[0018]
When receiving the event data, the end point process 33 registers the event data in the event management DB 35 (S5).
[0019]
FIG. 3 shows a configuration diagram of an example of a data format of event data transmitted from each host to the event management system 30. The event data format 50 in FIG. 3 includes a “data type” for identifying event data, an “importance” that stores the importance of the event, and a “host name” that stores the host name of the event data transmission source. “Text” in which text information related to event information is stored, and “health check flag” in which a flag indicating whether the event data is data for health check (hereinafter referred to as “health check data”) is stored. ”And the like.
[0020]
Here, the health check flag is a flag for determining whether or not the event data received by each process of the event management system 30 is health check data. Otherwise, “0” is stored. However, it is not always necessary if regular event data and health check data can be distinguished by other items. Differentiating with other items corresponds to, for example, embedding a character string indicating health check data in a text item.
[0021]
The system that can be monitored by the system health check program is not limited to the event management system 30 alone. That is, the number of processes in the system is not particularly limited, and the data format of event data transmitted from the host A or the like does not have to be the same as the event data format 50 of FIG. Furthermore, each process such as the origin process 31 does not need to operate on the same host. It is sufficient that a plurality of processes execute processing in series and the starting process that is the starting point of the processing and the process that is the end point of the processing are clear.
[0022]
Hereinafter, a processing procedure for the system health check program to confirm the operation of the event management system will be described. In the following description, it is assumed that the system health check program is installed in the host 20 in FIG. That is, the host 20 also serves as the system health check device 10. However, the system health check program and the system to be monitored do not necessarily have to operate in the same hardware, and the system health check device 10 and the host 20 are separate hardware connected via a network. It may be.
[0023]
FIG. 4 is a diagram for explaining the processing of the system health check program in the first embodiment.
[0024]
In step S10, the system health check program 11 is configured in the same format as the event data format 50 to the origin process 31, and transmits the health check data shown in FIG.
[0025]
FIG. 5 is a diagram illustrating an example of health check data. The health check data 51 of FIG. 5 is “D1” as “data type”, “general” as “importance”, “dummy” as “host name”, “healthcheck” as “text”, and “health check flag”. “1” is stored.
[0026]
Progressing to step S11 following step S10, the starting process 31 that has received the health check data 51 checks the health check flag of the health check data 51, so that the received health check data 51 is not regular event data, Recognize that it is health check data. Accordingly, the starting process 31 transmits the health check data 51 to the intermediate process 32 without executing the writing process to the host management DB 34 so that the influence of the health check data 51 does not affect the host management DB 34.
[0027]
Progressing to step S12 following step S11, the intermediate process 32 executes predetermined processing, and transmits the received health check data 51 to the end point process 33. The intermediate process 32 does not execute processing that causes inconvenience due to processing the health check data 51 in the same manner as regular event data, such as writing to the database, so that the health check data 51 is health check data. Perform normal processing without being conscious of it.
[0028]
Progressing to step S13 following step S12, the end point process 33 that has received the health check data 51 confirms the health check flag of the health check data 51 so that the received health check data 51 is not regular event data. Recognize that it is health check data. Therefore, the end point process 33 does not execute the writing process to the event management DB 35 so that the influence of the health check data 51 does not affect the event management DB 35, and notifies that the process is completed (hereinafter referred to as “completion notification”). .) Is transmitted to the system health check program 11.
[0029]
The system health check program 11 confirms that the event management system 30 is operating normally by receiving a completion notification from the end point process 33. On the other hand, if the system health check program 11 cannot receive a completion notification from the end point process 33 even after a predetermined time has elapsed (timed out) after sending the health check data 51 to the origin process 31, the system health check program 11 It is determined that an abnormality has occurred, and an error panel display and a process for notifying the abnormality are executed. Note that the time-out time may be determined based on the processing time of each process of the event management system 30. The system health check program 11 periodically confirms the operation of the event management system 30 by periodically repeating the transmission process of the health check data 51 in step S10.
[0030]
According to the system health check program 11 in the first embodiment described above, only the notification process for the system health check program 11 is added only to at least the end point process 33 among a plurality of processes that continuously execute processing. The operation of the event management system 30 can be confirmed. Further, when there is a process that performs data registration processing in the database, such as the start process 31 and the end process 33, that is, a process that causes inconvenience when the health check data 51 is processed in the same manner as regular event data. A process for determining whether or not the health check data 51 exists is added only to such a process, and a process that does not cause any inconvenience even if the health check data 51 is processed in the same manner as regular event data, as in the intermediate process 32. There is no need to add any special processing.
[0031]
In addition, when there are many processes that require distinction between the regular event data and the health check data 51, or it is not necessary to confirm that each process is normally performed, If it is only necessary to confirm that the event data is received, the event data reception process in each process may be set in a common library. That is, when the event data is received, the health check flag of the event data is confirmed, and if it is determined to be the health check data, the process of sending to the next process is a common function. The function may be used for the reception process.
[0032]
Next, a case where the process of the event management system 30 branches depending on the contents of event data will be described as a second embodiment.
[0033]
FIG. 6 is a diagram for explaining the process of the health check program in the second embodiment. In FIG. 2, the starting point process 131 is the same as the starting point process 31 in the first embodiment, and a description thereof will be omitted. When the intermediate process 132 receives the event data, the intermediate process 132 performs a predetermined process, and changes the end point process that transmits the event data according to the importance of the event data, or discards the event data. Fulfill. As end point processes, there are _m processes from end point processes E _{1 to} E _m 135, and processing according to the importance of event data is executed.
[0034]
The system health check program 111 is the same as the system health check program 11 in the first embodiment in that it transmits health check data to the starting point process 131 and receives a completion notification from the end point process. However, in order to confirm the operation including the branch process in the intermediate process 132, the health check data list table 112 is provided in advance to transmit the health check data corresponding to the variation of the branch process. In addition, in order to determine whether or not the transmission source of the completion notification is an end point process corresponding to the health check data, an end process confirmation table 113 is provided in advance.
[0035]
FIG. 7 shows a configuration diagram of an example of the health check data list table. The health check data list table 112 in FIG. 2 stores four health check data with data types “D ₁ ”, “D ₂ ”, “D ₃ ”, and “D ₄ ”. The respective importance levels are “important”, “general”, “warning”, and “ignore”. System Health Check program 111 from _{D 1} sequentially transmits, to the starting point process 131.
[0036]
FIG. 8 is a configuration diagram of an example of the health check data / end process correspondence table. The health check data / end process correspondence table 113 (hereinafter referred to as “correspondence table 113”) in FIG. 8 is the end process for the health check data D _{1 to} D ₄ in FIG. It is a table that manages whether or not. That is, for each health check data, the end process related to the cell in which 1 is stored is the end process when the health check data is used. For example, when the health check data having the data type “D ₁ ” (hereinafter referred to as “health check data D ₁ ”) is used, the end process E ₁ or _Em is the end process, and the health check data D ₂ is when using it can be seen that termination process E ₂ is an end process. With respect to the health check data D _4, it can be seen that no termination process. This health check data D _4, because of importance, as shown in FIG. 7 is "ignore", since is discarded by the intermediate process 132.
[0037]
Hereinafter, the process of the system health check program 111 in the second embodiment will be described with reference to FIG.
[0038]
In step S <b> 20, the system health check program 111 extracts one health check data from the health check data list table 112. First retrieve the health check data D _1.
[0039]
Proceeds to step S21 following step S20, system health check program 111 transmits a health check data _{D 1} as a starting point the process 131. Origin process 131 that has received the health check data D ₁ executes the same processing as the starting point the process 31 of the first embodiment, transmits a health check data D ₁ to the intermediate process 132 (S22).
[0040]
Proceeds Following step S22 in step S23, the intermediate process 132 confirms the importance of the health check data D _1, transmits a health check data D ₁ to endpoint process accordingly. For example, when the transmission destination when the importance is “important” is the end point process E ₁ , the intermediate process 132 transmits the health check data D ₁ to the end point process E ₁ .
[0041]
Proceeds to step S24 following step S23, the end point process E ₁ executes predetermined processing, and transmits a completion notification to the System Health check program 111.
[0042]
Progressing to step S25 following step S24, the system health check program 111 refers to the correspondence table 113 to confirm whether or not the transmission source of the completion notification is a correct end process. If the system health check program 111 cannot receive a completion notification from the end point process even after a predetermined time has elapsed (timed out) after sending the health check data to the start point process 131, an abnormality has occurred. The determination is the same as in the first embodiment. However, in the correspondence table 113, if the end point process is not as D _4, it is determined that the intermediate process 132 a health check data D ₄ is discarded as expected.
[0043]
The system health check program 111 determines whether the event management system 130 is operating normally by executing the above-described processing from step S20 to step S25 for each health check data in the health check data list table 112. can do.
[0044]
Further, details of the termination process determination process in step S25 will be described. FIG. 9 shows a flowchart of the end process determination process of the system health check program.
[0045]
In step S100, the system health check program 111, send a health check data D _n as a starting point the process receives the completion notification from the termination process E _m through the above processing.
[0046]
Progressing to step S101 following step S100, the system health check program 111 refers to the correspondence table 113 and confirms whether or not the value of the cell related to the combination of D _n and E _m is 1. If the value is 1, the process proceeds to step S102, where the system health check program 111 determines that the completion notification has been transmitted from the expected end point process, and determines that the event management system 130 is operating normally. If the value is 0, the process proceeds to step S103, where the system health check program 111 determines that the completion notification has been transmitted from an end point process different from the expected end point process, and an abnormality has occurred in the event management system 130. to decide.
[0047]
As described above, according to the system health check program 111 in the present embodiment, it is possible to easily check the operation even when the process of the system to be monitored is branched.
