Description

  The present invention relates to a log processing system that processes log information indicating a processing history in an information processing apparatus, and particularly to a log processing system that processes log information generated when distributed object processing is performed by a plurality of information processing apparatuses. And effective technology.

  Conventionally, when providing a service (a function realized by executing a program or an object) by performing processing in a distributed manner by a plurality of information processing devices, such as distributed object processing, log information indicating the processing history is provided for each log information. Since log information is distributed to multiple information processing devices because it is generated by information processing devices, log information in each information processing device must be matched when collecting log information such as investigating the cause of errors. It is necessary to check which log information is caused by which processing request.

  In addition, in order to perform such matching efficiently, an information processing device called a log manager that collects logs in one place is used, and the manager collects log data from multiple agents via the network. A system has also been proposed (see, for example, Patent Document 1).

Communication message to be transmitted to the client side processing device), and the extracted log information and the log information generated by execution of the predetermined processing are sequentially read from the storage means and added to the generated communication message Then, the communication message to which the log information is added is transmitted to the destination information processing apparatus by the communication means.

  If the destination information processing device that has received the communication message with the log information added is the next server-side processing device, the same processing as the second information processing device is performed, and the log information is further transmitted to the communication message. Add to and send. If the destination information processing device is the client side processing device that first transmitted the communication message, the log information is extracted from the received communication message, stored in the storage means, and then extracted from the communication message. The stored log information is stored in a predetermined recording area such as a log file allocated on the storage means. Here, the server-side processing device that first receives the communication message from the client-side processing device may store it in a predetermined recording area such as a log recording file.

  FIG. 2 is a diagram showing an overview of a conventional log collection process. As shown in FIG. 2, in the conventional log collection process, log information is distributed for each node when accessing multiple servers by distributed object processing. Needed to match logs between servers, and it took time to collect log information and analyze the collected log information.

  FIG. 3 is a diagram showing an outline of log collection processing by a conventional log manager. As shown in FIG. 3, in the log collection processing by the log manager, logs are collected in one log manager and managed centrally, log information is managed by time and ID, and log collection is performed efficiently. Since log information is collected in one place, there is a problem that it easily becomes a bottleneck or a critical point.

  In addition, since there is no log on the client side regardless of whether it is distributed to the server in FIG. 2 or collected in the log manager in FIG. Need to get the logs.

  FIG. 4 is a diagram showing an outline of the log collection processing of this embodiment. As shown in FIG. 4, in the log collection processing of this embodiment, log information is added to the communication message in a form that is not visible to the user or application program, and the log is stored not in each server but in the communication message itself. As a result, any node on the communication can acquire a log of events that have occurred so far in the communication. For this reason, each processing device such as a client can collect its own log information by its own device, and since past log information is distributed to each processing device such as a client, Efficient use of resources can be achieved.

  FIG. 5 is a diagram showing an outline of communication processing during application processing according to the present embodiment. As shown in FIG. 5, in the transmission interceptor process and the reception interceptor process of this embodiment, additional information is added to the communication content during communication between UAPs (User Application Programs), for example, like the interceptor function of the distributed object platform program. Log information is added to a communication message by providing a function. At that time, in each node, the log information generated in the own node is added to the communication message to be transmitted in a place that is not visible to the user or application program such as the service context of the distributed object platform program.

  FIG. 6 is a diagram illustrating recording of a log in the memory at the time of log collection processing according to the present embodiment. As shown in FIG. 6, when receiving a communication message, each node in the present embodiment extracts log information added to the communication message from the communication message and records it in a storage device such as a memory. In the case of the Java language, the recording is performed in a place such as ThreadLocal unique to the thread. If a log generated before the current node is recorded in the memory at the time of transmission of the communication message, the log is taken out of the memory and added to the communication message to be transmitted.

  Hereinafter, in the log processing system according to the present embodiment, a log information addition process when a communication message transmission request is issued by a process of a user application program will be described. In the log processing system of this embodiment, when a transmission request for a communication message is issued by processing of a user application program, transmission interceptor processing is started by a software interceptor function that constitutes a communication platform such as a distributed object platform program.

  FIG. 7 is a flowchart showing the processing procedure of the transmission interceptor processing of this embodiment. When a communication message transmission request is issued by the processing of the user application program, in step 701, the transmission interceptor processing unit 101 of the client side processing device 100 or the transmission interceptor processing unit 112 of the server side processing device 110 issues the transmission request. The thread number for identifying the processed application is acquired and stored in the memory.

  In step 702, the thread-specific memory area identified by the acquired thread number is accessed to check whether additional identification information for identifying log information to be added to the communication message is stored, and the additional identification If information is stored, the identification information is read from the memory area specific to the thread and added to the communication message. Here, the additional identification information is set in advance by the user depending on how much log information is collected, but is set by each information processing apparatus according to the congestion status of the communication traffic and the error occurrence status. It is good as a thing.

  In step 703, the memory area specific to the thread is accessed to check whether the log information output by the processing of the application program is stored in the memory, and the log information is stored in the memory area specific to the thread. If yes, go to Step 704.

  When the server-side processing apparatus 110 according to the present embodiment executes a predetermined user application process using a communication message received from another information processing apparatus, a predetermined process request such as a method call is issued by the process. Log information indicating the contents is output, and the log information is stored in a thread-specific memory area corresponding to the thread number of the application process. For this reason, when a transmission request is issued after executing the application process, log information of the executed predetermined process is stored in the thread-specific memory area. In addition, as described in FIG. 9, when log information is received from another information processing apparatus, log information in the other information processing apparatus is also stored in the thread-specific memory area.

  FIG. 8 is a diagram illustrating a data structure example of log information according to the present embodiment. As shown in FIG. 8, the client-side processing device 100 and the server-side processing device 110 of this embodiment indicate the thread number 801 for identifying the application process that output the log information, and the date and time when the log information was output. Date and time information 802, a node name 803 indicating the information processing apparatus that has executed the process, a process name indicating the name of the method that executed the process, and a status 805 that indicates the status when the log information of the process is recorded In addition, input / output data 806 indicating error messages and input / output data when the log information is recorded are stored in a thread-specific memory area.

  In step 704, a record is read from the log information stored in the memory area specific to the thread and stored in the memory. Then, the process proceeds to step 705, and the additional identification information corresponding to the record stored in the memory is handled. Log contents to be acquired and stored in another area of memory. For example, when the additional identification information indicates the addition of log information indicating the process executed at each node, the log contents from the thread number 801 to the process name 804 are acquired, and the additional identification information is stored in each node. The log contents from the thread number 801 to the status 805 are displayed, and the additional identification information indicates the addition of all log information. In some cases, the entire contents of the record are acquired and stored in another area of the memory.

  In step 706, the status 805 in the record stored in the memory is referred to, and it is checked whether or not the status 805 referred to indicates the occurrence of an error. Proceed to step 707.

  In step 707, information indicating the content of the error is acquired from the records stored in the memory and added to the other area of the memory. For example, the contents of the input data, error message, and output data stored in the input / output data 806 from the record immediately before the record in which the status 805 is an error to the record immediately after is acquired as information indicating the content of the error. And add it to the other area of the memory. Further, all the log contents from the record immediately before the record whose status 805 is an error to the record immediately after it may be used as information indicating the content of the error.

  In step 708, the log content stored in another area of the memory is added to the communication message transmitted to the other information processing apparatus. In this addition processing, for example, addition is performed in a place that is not visible to the user or application program, such as a service context of a distributed object platform program.

  In step 709, it is checked whether all records stored in the memory area specific to the thread have been read. If all records have not been read yet, the process returns to step 704 and the next record is read. When the reading of is completed, the process proceeds to step 710.

  In step 710, the communication message to which the additional identification information or log information is added is transmitted by the communication device to the information processing device of the transmission destination.

  In the above process, a communication message with log information added is transmitted when a normal communication message is transmitted, but a communication message without log information is transmitted during normal transmission, such as a time zone with a low communication load. By transmitting a communication message with log information added thereto, a communication process dedicated to log collection may be performed, which is different from the communication process of transmitting / receiving a communication message with no log information added. As a result, it is possible to prevent a decrease in communication performance when the amount of communication increases due to the addition of log information.

  Next, in the log processing system according to the present embodiment, a process for extracting log information and recording the log information in a file when a communication message is transmitted from another information processing apparatus will be described. In the log processing system according to the present embodiment, when a communication message is transmitted from another information processing apparatus, reception interceptor processing is started by an interceptor function of software constituting a communication infrastructure such as a distributed object infrastructure program.

  FIG. 9 is a flowchart showing a processing procedure of the reception interceptor of the present embodiment. When a communication message is transmitted from another information processing device, the reception interceptor processing unit 111 of the server side processing device 110 or the reception interceptor processing unit 102 of the client side processing device 100 receives the transmitted communication message in step 901. And store it in memory.

  In step 902, the thread number of the thread for processing the communication message stored in the memory is acquired, and a memory area specific to the thread is secured in the memory.

  In step 903, the additional identification information is read from the communication message stored in the memory and stored in the thread-specific memory area. Thereafter, referring to the storage location of the log information of the communication message in the memory, the log information is extracted.

  In step 904, it is checked whether or not log information has been extracted from the communication message by the log information extraction process. If log information is extracted, the process proceeds to step 905. In step 905, log information extracted from the communication message is stored in the reserved thread-specific memory area.

  In step 906, it is checked whether or not recording instruction information indicating that it is necessary to record log information by accessing a predetermined area in the memory in the information processing apparatus, and the recording instruction information is stored. If YES in step 907, the flow advances to step 907 to write the log information stored in the thread-specific memory to a log recording file allocated on the magnetic disk device.

  The recording instruction information is set in advance by a user who intends to collect log information, but the request is first received from the client side processing device 100 that issues the request first or the client side processing device 100. It may be set in advance in the server-side processing device 110 to collect log information in a log recording file in those devices.

  Next, in the log processing system according to the present embodiment, as shown in FIG. 4, requests and responses are transmitted and received by the client side processing device 100 and the server side processing device 110, and the services provided by the server 1 and the server 2 are transmitted to the client. The process of collecting log information and recording the log information in the log recording file of the client side processing apparatus 100 will be described.

  When a request for transmitting a request for receiving a service by the server 1 is issued by the processing of the user application program in the client of FIG. 4, the transmission interceptor processing unit 101 of the client side processing apparatus 100 in step 701 of FIG. The thread number of the application process is acquired and stored in the memory. In step 702, additional identification information is read from the memory area specific to the thread identified by the acquired thread number and added to the request.

  Next, in step 703, it is checked whether or not log information is stored in the thread-specific memory area. However, since there is no log information on the client side, the process proceeds to step 710, where the additional identification information is added. The request is transmitted to the destination server 1 by the communication device.

  When a request is transmitted from the client to the server 1 as shown in FIG. 4, the reception interceptor processing unit 111 of the server 1 receives the transmitted request and stores it in the memory in step 901, and in step 902, the thread A unique memory area is secured in the memory.

  Next, in step 903, after the additional identification information is read from the request stored in the memory and stored in the thread specific memory area, the log information is extracted from the request, but the log information is not yet stored. Therefore, the process is terminated through step 904.

  Thereafter, when the server 1 executes a user application process for providing a predetermined service in response to a request received from the client, the server 1 indicates the contents when a predetermined process request such as a method call is issued by the process. Log information “S1 log” is stored in the reserved thread-specific memory area.

  Whether a request to another server or a response to the client is issued as a result of the user application processing in the server 1 depends on the processing content, but here, from the server 1 to the server 2 as shown in FIG. In step 701, the transmission interceptor processing unit 112 of the server 1 obtains a thread number for identifying the application process that issued the transmission request. In step 702, a thread-specific memory is acquired. The additional identification information is read from the area and added to the request.

  In the processing from step 703 to step 709, log information “S1 log” is acquired from the thread specific memory area according to the additional identification information and added to the request. In step 710, the additional identification information and log information “S1 log” are added. "Is added to the server 2 by the communication device.

  As shown in FIG. 4, when a request with log information “S1 log” is transmitted from the server 1 to the server 2, the reception interceptor processing unit 111 of the server 2 receives the transmitted request in step 901. In step 902, a thread-specific memory area is secured in the memory.

  Next, in step 903, the additional identification information is read from the request stored in the memory and stored in the memory area specific to the thread. Then, the log information “S1 log” is extracted from the request. Log information “S1 log” is stored in a thread-specific memory area.

  In step 906, whether or not recording instruction information indicating that recording of log information is necessary is stored by accessing a predetermined area in the memory in the server 2, the server 2 stores the recording instruction information. If it is not stored, the process ends here.

  Thereafter, when the server 2 executes a user application process for providing a predetermined service according to the request received from the server 1, the contents are displayed when a predetermined process request such as a method call is issued by the process. The indicated log information “S2 log” is added to the reserved thread-specific memory area.

  As a result of the user application processing in the server 2, if the response from the server 2 to the server 1 is issued as shown in FIG. 4, the transmission interceptor processing unit 112 of the server 2 issues the transmission request in step 701. A thread number for identifying an application process is acquired, and in step 702, additional identification information is read from the thread-specific memory area and added to the response.

  In the processing from step 703 to step 709, log information “S1 log, S2 log” is acquired from the memory area specific to the thread according to the additional identification information and added to the response. In step 710, the additional identification information and log information are acquired. A response to which “S1 log, S2 log” is added is transmitted to the server 1 by the communication device.

  As shown in FIG. 4, when a response with log information “S1 log, S2 log” is transmitted from the server 2 to the server 1, the reception interceptor processing unit 111 of the server 1 sends the transmitted response in step 901. In step 902, a thread-specific memory area is secured in the memory.

  Next, in step 903, the additional identification information is read from the response stored in the memory and stored in the memory area specific to the thread. Then, the log information “S1 log, S2 log” is extracted from the response. The log information “S1 log, S2 log” is stored in the thread-specific memory area.

  In step 906, whether or not recording instruction information indicating that recording of log information is necessary is stored by accessing a predetermined area in the memory in the server 2 is stored. If it is not stored, the process ends here.

  Thereafter, when the server 1 executes the user application process corresponding to the response received from the client, the log information “S1 log 2” indicating the contents when a predetermined process request such as a method call is issued by the process is issued. Is added to the reserved thread-specific memory area.

  As a result of the user application process in the server 1, if a response from the server 1 to the client is issued as shown in FIG. 4, the transmission interceptor processing unit 112 of the server 1 issues the transmission request in step 701. A thread number for identifying the process is acquired, and in step 702, additional identification information is read from the thread specific memory area and added to the response.

  In the processing from step 703 to step 709, log information “S1 log, S2 log, S1 log 2” is acquired from the memory area specific to the thread according to the additional identification information and added to the response. In step 710, the additional identification is performed. The response to which the information and log information “S1 log, S2 log, S1 log 2” are added is transmitted to the client by the communication device.

  When the response with the log information “S1 log, S2 log, S1 log 2” is transmitted from the server 1 to the client as shown in FIG. 4, the reception interceptor processing unit 102 of the client side processing apparatus 100 in step 901 The transmitted response is received and stored in the memory. In step 902, a thread-specific memory area is secured in the memory.

  In step 903, log information “S1 log, S2 log, S1 log 2” is extracted from the response. In step 905, log information “S1 log, S2 log, S1 log 2” is stored in the memory area unique to the thread. Is stored.

  In step 906, it is checked whether or not recording instruction information indicating that log information needs to be recorded is accessed by accessing a predetermined area in the memory in the client, and the recording instruction information is stored in the client. If YES in step 907, the flow advances to step 907 to write the log information “S1 log, S2 log, S1 log 2” stored in the thread-specific memory to a log recording file allocated on the magnetic disk device.

  As described above, in the log processing system according to the present embodiment, log information is added to a communication message in the order in which the log information is generated. Therefore, a plurality of log information is matched and which log information is caused by which processing request. There is no need to check whether there is any, and the problem that it takes time to analyze log information can be solved.

  In addition, when a log manager is used in the prior art, since log information is collected in one place, there is a problem that it tends to become a bottleneck or a critical point. Since log information is distributed to each issued client-side processing device (or the server-side processing device that received the request first), a specific information processing device does not become a bottleneck or a critical point.

  As described above, according to the log processing system of the present embodiment, log information is stored in a communication message itself by adding log information to the communication message for executing a predetermined process.
