Description

  The present invention relates to a network system, a relay processing apparatus, and a log information management method, and more particularly to a network system, a relay processing apparatus, and a log information management method for managing log information related to message processing.

  In a network system in which messages are relayed in a relay manner by a plurality of relay processing devices, conventionally, log information related to messages has been recorded in a log file provided for each relay processing device.

FIG. 1 is a diagram showing a log information management form in a conventional network system. In FIG. 1, relay processing devices 500a, 500b, and 500c (hereinafter collectively referred to as “relay processing device 500”) are relay processing devices that relay messages. In the figure, a practical arrow between the relay processing devices 500 indicates a route of the message α. A broken arrow indicates a route of the message β. That is, the message α is relayed by the relay processing devices 500a and 500c. The message β is relayed by the relay processing devices 500a, 500b, and 500c.

  However, according to the form shown in FIG. 1, it is necessary to provide a log file for each relay processing device 500. Therefore, a process for recording log information is required for each relay processing apparatus, and the performance of the entire network system may be deteriorated depending on the processing time.

  In addition, since log files are distributed and arranged in each relay processing device, when a failure occurs, the log file of each relay processing device is individually specified to identify the relay processing device that caused the failure. A complicated operation such as checking or merging and investigating log files of each relay processing device is required.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a network system, a relay processing device, and a log information management method capable of more easily managing log information related to processing of a message. .

  In order to solve the above problem, the present invention is a network system that relays a message by a plurality of relay processing devices, and the first relay processing device is configured to relay the message when the first relay processing device relays the message. The log information of the process related to the message is added to the message, and the second relay processing apparatus records the log information added to the message in a storage device.

  In such a network system, log information related to message processing can be managed more easily.

  ADVANTAGE OF THE INVENTION According to this invention, the network system, relay processing apparatus, and log information management method which can manage the log information regarding the process of a message more simply can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a diagram showing a configuration example of the network system in the embodiment of the present invention. 2 includes a plurality of log acquisition relay processing devices 10a, 10b, and 10c (hereinafter collectively referred to as “log acquisition relay processing device 10”) and a plurality of relay processing devices 20A1 and 20A2. , 20B1 to 20B4, 20C1, 20C2, and 20D1 (hereinafter collectively referred to as “relay processing device 20”) and a centralized management device 30. In the figure, a solid line connecting the log acquisition relay processing apparatus 10 or the relay processing apparatus 20 indicates a network (whether wired or wireless).

  The log acquisition relay processing device 10 and the relay processing device 20 are devices that relay messages. That is, in the network system 1, the message is relayed in a relay manner by the log acquisition relay processing device 10 or the relay processing device 20.

  The network system 1 is logically divided by a concept called “area”. In the drawing, an example of division into area A, area B, area C, and area D is shown. Area A includes relay processing devices 20A1 and 20A2 (hereinafter, collectively referred to as “relay processing device 20A”). Area B includes relay processing devices 20B1 to 20B4 (hereinafter collectively referred to as “relay processing device 20B”). Area C includes relay processing devices 20C1 and 20C2 (hereinafter collectively referred to as “relay processing device 20C”). Area D includes relay processing device D1.

  Each area is connected by the log relay processing device 10. In other words, it can be said that the area is a network system divided by the log relay processing device 10.

  The log acquisition relay processing device 10 and the relay processing device 20 are common in that they have a function of relaying a message, but are different in handling log information related to the message. That is, the log acquisition relay processing apparatus 10a records log information in the log file 110a, the log acquisition relay processing apparatus 10b records in the log file 110b, and the log acquisition relay processing apparatus 10c records log information in the log file 110c. The device 20 does not record the log information in the log file, but adds (records) it to a predetermined position (for example, behind the message) of the message.

  This point will be described in more detail. FIG. 3 is a diagram showing an outline of a log information management mode according to the embodiment of the present invention.

  In FIG. 3, relay processing devices 20a and 20b are the same relay processing devices 20 as shown in FIG. FIG. 3 shows an example in which a message α and a message β are relayed. The message α is relayed in the order of the relay processing device 20a and the log relay processing device 10. The message β is relayed in the order of the relay processing device 20a, the relay processing device 20b, and the log relay processing device 10.

  In such a case, the relay processing device 20a adds log information related to the message α to the back of the message α. The log information of the message β is added after the message β. In the figure, a message α51 and a message β52 are examples in which log information is added by the relay processing device 20a. In the figure, an example is shown in which a relay point, a process start time, and a process end time are recorded as log information. The relay point is information for identifying the relay processing device 20 or the log acquisition relay processing device 10 (hereinafter referred to as “relay point identification information”), for example, unique identification information on the network system 1 such as an IP address. It is. In the figure, “a” indicates the relay processing device 20 a, “b” indicates the relay processing device 20 b, and “c” indicates the log acquisition relay processing device 10. The processing start time is the time at which the relay processing device 20 or the log relay processing device 10 starts processing on the message or the time when the message is received. The processing end time is the time when the processing for the message is completed or the time when the message is sent out in the relay processing device 20 or the log relay processing device 10.

  Regarding the message β, log information is further added by the relay processing device 20b when passing through the relay processing device 20b. In the figure, the message β53 shows an example in which the relay point of the relay processing device 20b, the process start time, and the process end time are further added.

  The log acquisition relay processing device 10 acquires log information recorded in each message, and records the log information in the log file 110. In the figure, an example is shown in which log information of a message α and a message β is recorded in the log file 110. The log acquisition relay processing device 10 deletes the log information from the message after acquiring the log information.

  Note that the log acquisition relay processing device 10 acquires log information and records it in the log file 110 only for a message that goes out of the area (relayed across the area). This prevents log information related to the same message from being distributed. For example, in FIG. 2, the log acquisition relay processing device 10c is added to the message when it receives a message from the relay processing device 20B in the area B and transmits the message to the relay processing device 20C in the area C. Log information is recorded in the log file 110c. On the other hand, when the log acquisition relay processing device 10c receives a message from the relay processing device 20B in the area B and transmits the message to the relay processing device 20B in the area B, the log acquisition relay processing device 10c does not acquire the log information and relays the message. Log information is added (added) to the end of the message in the same manner as the processing device 20. Therefore, in the log acquisition relay processing device 10 that is an exit from the message area, log information in the area is managed with respect to the message.

  When each log acquisition relay processing device 10 relays a message relayed across areas, it notifies the centralized management device 30 of the relay of the message. As a result, the centralized management device 30 has, for each message, relay point identification information of the log acquisition relay processing device 110 that has become the entrance to the area, and relay point identification of the log acquisition processing device 110 that has become the exit from the area. Information is managed. In FIG. 2, the central management device 30 may be one for all areas, or one for each area. When one device is allocated for each area, log information management may be further hierarchized by providing a device that integrates the centralized management device 30.

  FIG. 4 is a diagram illustrating a hardware configuration example of the log acquisition relay processing device according to the embodiment of the present invention. The log acquisition relay processing device of FIG. 4 includes a drive device 100, an auxiliary storage device 102, a memory device 103, an arithmetic processing device 104, and an interface device 105 that are connected to each other via a bus B. Composed.

  A program for realizing processing in the log acquisition relay processing device is provided by a recording medium 101 such as a CD-ROM. When the recording medium 101 on which the program is recorded is set in the drive device 100, the program is installed from the recording medium 101 to the auxiliary storage device 102 via the drive device 100. However, the program need not be installed from the recording medium 101, and may be downloaded via a network.

  The auxiliary storage device 102 stores the installed program and also stores necessary files and data. For example, the log file 110 is recorded in the auxiliary storage device 102. The memory device 103 reads the program from the auxiliary storage device 102 and stores it when there is an instruction to start the program. The arithmetic processing device 104 executes functions related to the log acquisition relay processing device in accordance with a program stored in the memory device 103. The interface device 105 is used as an interface for connecting to a network.

  Note that the relay processing device 20 and the centralized management device 30 may be configured by hardware similar to that shown in FIG.

  Hereinafter, the processing procedure of the network system 1 will be described. FIG. 5 is a diagram for explaining a processing procedure of telegram relay processing in the network system according to the present embodiment. In the present embodiment, processing in area B will be described in particular when a message is relayed in the order of area A-area B-area C.

  When the log acquisition relay processing device 10a receives a message requested to be transmitted from the relay processing device 10A in area A into area B (S101), the log acquisition relay processing device 10a executes the relay processing of the message, for example, the log acquisition relay processing device 10a. The relay point identification information, the process start time and the process end time of the relay process are added to the message as log information (S102). If a failure or the like (for example, a shortage of resources such as memory) occurs in the relay process, the failure information is also added to the message as part of the log information. Subsequently, according to the destination determination logic, the log acquisition relay processing device 10a transmits a message with the log information added to any of the relay processing devices 20B connected to the log acquisition relay processing device 10a in the area B ( S103). The destination determination logic is a logic for determining a transmission destination of a message. The transmission destination of the electronic message may be determined based on the load of the relay processing device 20 that is a transmission destination candidate, or various methods such as determination according to a predetermined order can be applied. .

  The log relay processing device 10a transmits, for example, information (message identification information) that uniquely identifies the message and the relay point identification information of the log relay processing device 10a to the centralized management device 30 when the message is received. To do. In response to this, the central management apparatus 30 records the message identification information and the relay point identification information in association with each other and records them in the storage device (S401).

  Subsequently, the relay processing device 20B that has received the transmission of the message from the log acquisition relay processing device 10a executes the relay processing for the message, for example, the relay point identification information of the relay processing device 20, the processing start time of the relay processing, and The processing end time is added to the message as log information (S201). When a failure or the like occurs in the relay process, the failure information is also added to the message as part of the log information. Subsequently, the log acquisition relay processing device 10a transmits a message with the log information added thereto to the next relay processing device 20B in accordance with the destination determination logic (S202). Steps S201 and S202 are executed in each relay processing device 20B that relayed the message. Therefore, the log information of each relay processing device 20B is added to the message in the order in which the log information is relayed.

  When the message relayed by the relay processing device 20B reaches the log acquisition relay processing device 10c, the log acquisition relay processing device 10c determines whether or not the length of the message including the log information exceeds a specified value. If the specified value is exceeded (S301), the message is divided (S302). However, the message may not necessarily be divided.

  Subsequently, the log acquisition relay processing device 10c performs message relay processing, and determines whether the transmission destination of the message determined according to the destination determination logic is the relay processing device 20B in the area B (S303). . When the transmission destination of the message is the relay processing device 20B in the area B, for example, the relay point identification information of the log acquisition relay processing device 10c, the processing start time and the processing end time of the relay processing are added to the message as log information ( S304). When a failure or the like occurs in the relay process, the failure information is also added to the message as part of the log information. Subsequently, the log acquisition relay processing device 10c transmits a message with the log information added to the next relay processing device 20B according to the destination determination logic (S305).

  On the other hand, when the transmission destination of the message is the relay processing device 20 outside the area B (for example, the relay processing device 20C in the area C), the log acquisition relay processing device 10c adds the log information added (accumulated) to the message. Is output to the log file 110c (S306). Subsequently, the log acquisition relay processing device 10c deletes the log information added to the message from the message (S307). As a result, the message returns to the state before the log information is added. Subsequently, the log acquisition relay processing device 10c transmits the message identification information of the message and the relay point identification information of the log relay processing device 10b to the centralized management device 30 (S308). In response to this, the central management apparatus 30 records the message identification information and the relay point identification information in association with each other and records them in the storage device (S402). The centralized management apparatus 30 manages the information acquired in step S401 and the information acquired in step S402 in association with each other based on the message identification information. As a result, the centralized management device 30 can identify the log acquisition relay processing device 10a serving as the entrance in the area B and the log acquisition relay processing device 10c serving as the exit for the message.

  Subsequently, the log acquisition relay processing device 10c sends the message to the relay processing device 20C in the area C (S309). The log acquisition relay processing apparatus 10c is an exit in the area B and an entrance in the area C. Therefore, before sending to the relay processing device 20C in step S309, the log acquisition relay processing device 10c executes the processing performed by the log acquisition relay processing device 10a in steps S101 to S103 as an entrance to area C.

  Next, a process for investigating a failure of the network system 1 based on log information added to a message will be described. FIG. 6 is a diagram for explaining failure investigation processing in the network system according to the present embodiment.

  Although the description is omitted in FIG. 5 for the sake of convenience, when the log acquisition relay processing apparatus 10c serving as an exit from the area B acquires the log information history from the message (S311), the log information history is analyzed, and the message It is determined whether or not there is a failure related to the relay (S312). For example, when the fault information is included in the log information, the processing time of a certain relay processing device 20 exceeds a specified value, or the transmission time between two relay processing devices 20 exceeds the specified value If it is, it is determined that there is a failure. The processing time of a certain relay processing device 20 may be calculated based on the processing start time and the processing end time in the log information of the relay processing device 20 in the log information history. The transmission time may be calculated based on the processing end time of the previous relay processing device 20 and the processing start time of the next relay processing device 20 recorded in the log information history.

  If no failure is detected, normal relay processing as described in FIG. 5 is executed. On the other hand, when a failure is detected, the log acquisition relay processing device 10c notifies the central management device 30 of the detection of the failure (S313). At this time, at least the relay point identification information of the relay processing device 20 in which the failure is detected is notified. Also, route information within the area B of the message may be notified. The route information is, for example, information in which relay point identification information is arranged in the order in which the message has passed, and is created based on the log information history.

  Receiving the notification of the failure detection, the centralized management apparatus 30 creates a failure investigation message (hereinafter referred to as “survey message”) (S411).

  FIG. 7 is a diagram illustrating an example of a survey message. In FIG. 7, a survey message 60 includes a message type identifier, a survey target identifier, survey details, route information, and the like. The message type identifier is information for allowing the log acquisition relay processing device 10 and the relay processing device 20 to identify that the message is the investigation message 60. For example, if this value is “1”, the message is identified as the survey message 60. The investigation target identifier is relay point identification information of the relay processing device 20 in which a failure is detected. The contents of the investigation include, for example, the contents of the investigation processing to be executed by the relay processing apparatus 20 to be investigated, such as acquisition of the memory usage status, acquisition of the buffer usage status, or acquisition of the number of disk access errors. Execution instruction). The route information is route information related to a message in which a failure is detected.

  Subsequently, the centralized management device 30 instructs the transmission of the survey message 60 to the area B by transmitting the survey message 60 to the log acquisition relay processing device 10a that has become the entrance to the area B based on the route information. (S412).

  The log acquisition relay processing device 10a that has received the survey message 60 transmits the survey message 60 to the next relay processing device 20B in accordance with the route information included in the survey message 60 (S111). When the relay processing device 20B receives the survey message 60, the relay processing device 20B determines whether or not it is the survey target based on the survey target identifier included in the survey message 60 (S211). If not, the relay processing device 20B transmits the survey message 60 to the next relay processing device 20B according to the route information (S214). In the case of the investigation target, the relay processing device 20B executes the investigation according to the investigation content specified in the investigation message 60, and as a result, investigation information (for example, memory usage status, buffer usage status, or disk access error) The number of times is acquired (S212). Subsequently, the relay processing device 20B adds the survey information to the survey message 60 (S213).

  FIG. 8 is a diagram illustrating an example of a survey message to which survey information is added. In FIG. 8, survey information is added to the end of the survey message 60a.

  Subsequently, the relay processing device 20B transmits a survey message 60a to the next relay processing device 20B according to the route information (S214).

  As a result of relaying the survey message 60a according to the route information, when the log acquisition relay processing device 10c at the exit of area B receives the survey message 60a (study information acquired message) (S314), the log acquisition relay processing device 10c The electronic message 60a is transmitted to the central management apparatus 30 (S315).

  Upon receiving the survey message 60a, the centralized management device 30 performs a survey of the cause of the failure based on the survey information added to the survey message 60a (S413). The investigation of the failure may be automatically performed by the centralized management device 30 or may be performed by an administrator or the like.

  Note that route information is not necessarily required in the survey message 60. In this case, according to the normal destination determination logic, the survey message 60 is transmitted to the relay processing device 20B to be investigated. However, by transmitting the survey message 60 according to the route information, the same route as when the failure is detected can be reproduced.

  Next, a description will be given of processing executed to recover a failure when the occurrence of the failure is detected based on the log information or when the cause of the failure is confirmed based on the investigation information. FIG. 9 is a diagram for explaining failure recovery processing in the network system according to the present embodiment.

  First, the centralized management apparatus 30 creates a failure recovery message (hereinafter referred to as a “failure recovery message”) based on log information or investigation information (S421).

  FIG. 10 is a diagram illustrating an example of a failure recovery message. In FIG. 10, a failure recovery message 70 includes a message type identifier, a failure recovery target identifier, failure recovery processing content, route information, and the like. The message type identifier is information for causing the log acquisition relay processing device 10 and the relay processing device 20 to identify that the message is the failure recovery message 70. For example, if this value is “2”, the message is identified as the failure recovery message 70. The failure recovery target identifier is relay point identification information of the relay processing device 20 that is a failure recovery target. The content of the failure recovery processing is the content of failure recovery processing (execution command for failure recovery processing) to be executed by the relay processing device 20 that is the target of failure recovery, such as clearing the memory, buffer, etc., changing parameters, and the like. The route information is route information related to a message in which a failure is detected.

  Subsequently, the centralized management device 30 transmits the failure recovery message 70 to the log acquisition relay processing device 10a that has become the entrance to the area B for the message based on the route information, so that the area B of the failure recovery message 70 is transmitted. Is instructed to transmit to (S422).

  The log acquisition relay processing device 10a that has received the failure recovery message 70 transmits the failure recovery message 70 to the next relay processing device 20B in accordance with the path information included in the failure recovery message 70 (S121). When the relay processing device 20B receives the failure recovery message 70, the relay processing device 20B determines whether it is a failure recovery target based on the failure recovery target identifier included in the failure recovery message 70 (S221). If it is not a failure recovery target, the relay processing device 20B transmits a failure recovery message 70 to the next relay processing device 20B according to the path information (S224). If it is a failure recovery target, the relay processing device 20B executes the failure recovery processing according to the content of the failure recovery processing specified in the failure recovery message 70 (S222). Subsequently, the relay processing device 20B acquires information (for example, memory usage status, buffer usage status, or disk access error count) indicating the failure recovery status (S222), and uses the failure recovery status information as a failure recovery message. 70 is added (S223).

  FIG. 11 is a diagram illustrating an example of a failure recovery message to which failure recovery status information is added. In FIG. 11, failure recovery status information is added to the end of the failure recovery message 70a.

  Subsequently, the relay processing device 20B transmits the failure recovery message 70a to the next relay processing device 20B according to the route information (S224).

  As a result of relaying the failure recovery message 70a according to the route information, when the log acquisition relay processing device 10c at the exit of area B receives the failure recovery message 70a (failure recovery completed message) (S321), the log acquisition relay processing device 10c The failure recovery message 70a is transmitted to the central management apparatus 30 (S322).

  Upon receiving the failure recovery message 70a, the centralized management device 30 executes confirmation of the failure recovery status and the like based on the failure recovery status information added to the failure recovery message 70a (S423). The confirmation of the failure recovery status may be automatically performed by the centralized management device 30 or may be performed by an administrator or the like.

  6 and 9, the log acquisition relay processing device 10c serving as an area exit may perform the processing performed by the centralized management device 30.

  As described above, according to the network system 1 in the present embodiment, the log information is added to the message in the relay processing device 20 and is written in the log file 110 only in the log acquisition relay processing device 10. Therefore, the log file writing function in the relay processing device 20 can be omitted. Also, the log information writing time in the relay processing device 20 can be omitted, and the message passing time in the entire network system can be shortened.

  Further, since the log information of the relay processing device 20 is added in the order of passing, the log information added to the message is analyzed without collecting or merging the log information from the plurality of relay processing devices 20. Only the route of the message and the transit time at each relay point can be grasped. Therefore, time and labor required for collecting and merging log information can be omitted, and timely network monitoring and quick response when a failure occurs can be realized.

  Further, at the time of investigation or failure recovery processing, route information is added to the investigation message 60 or failure recovery message 70, and the investigation message 60 or failure recovery message 70 is relayed according to the route information. And the investigation information can be acquired and the failure recovery process can be executed in a state closer to the time of the failure.

  The message passage route in the area is stored in the log acquisition relay processing device 10 when the message leaves the area, and the relay point of the log acquisition relay processing device 10 when the message enters and exits the area. Since the identification information is acquired by the centralized management device 30, it is possible to efficiently manage the passage paths of all the messages that have passed through the area. That is, if all the log information is managed by the centralized management device 30, the disk capacity of the centralized management device 30 may be compressed or the network load on the centralized management device 30 may increase.

  In addition, you may make it manage a passage path | route about all the messages which pass through several areas by installing the integrated centralized management apparatus hierarchically integrating the centralized management apparatus 30. FIG. In this case, it is possible to trace a route, collect failure information, and repair a failure even when a failure occurs in a plurality of areas.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
