Description

  The present invention relates to an information processing apparatus, a log processing method, and a program that acquire a processing result from a processing server based on a processing request received from a terminal.

  In the Web system, a Web server receives a processing request from a client terminal, and requests an application (AP) server for processing based on the processing request. The AP server executes the requested application program and returns the processing result to the Web server. The Web server generates screen drawing information based on the processing result, and returns the screen drawing information to the client terminal. The client terminal draws a Web page based on the received screen drawing information and displays it on the display device.

  In this way, one transaction is executed in cooperation between the Web server and the AP server. In the following description, an application program may be simply referred to as an application.

  In such a WEB system, a technique is known in which a log management server records a plurality of logs respectively generated in a Web server and an AP server during transaction execution in an actual processing order. In this technique, each server adds transaction identification information (ID) and order information to a log message and transmits the log message to a log management server. Then, the log management server records a plurality of log messages in the actual processing order based on the transaction ID and order information of the received log messages.

  In addition, a technique for collecting processing records of a client device in a server is also known. In this technique, script code for recording processing of a client device is inserted into a response from a Web server in response to a request from the client device. By interpreting and executing the script code, the client device generates a processing record when a response is received, when rendering of the web browser is completed, and when a request for the next web page is transmitted. The generated process record is transmitted to the record collection server via the web server, and is recorded together with the process record of the web server.

  The processing record generated by the client device can include communication time from request to response, drawing time required for drawing a Web page, browsing / operation time, and the like.

The conventional Web system described above has the following problems.
When the log management server records a plurality of logs generated in the Web server and the AP server in the actual processing order, for example, it can be used for investigating the cause when some failure occurs. In addition, if the total processing time from when the client terminal sends a processing request until the drawing of the screen is completed and the drawing time required for drawing the screen are measured, it is stored in the log management server as a log of the client terminal. Can be collected. Further, by managing the log of the Web server, the log of the AP server, and the log of the client terminal in association with each other, for example, it can be useful for determining whether the cause of the failure is the client terminal, the Web server, or the AP server. .

  On the other hand, if a user who performs a business using a Web system receives a complaint that the processing time of the business is long, it is necessary to investigate the cause of the problem, and it is desirable to improve if possible. In this case, first, the cause investigation is started from estimating which transaction is a complaint among many transactions executed by the Web system.

  A transaction is defined as a series of processes of a client terminal, a Web server, and an AP server from when a client terminal transmits a processing request until screen rendering ends. As logs belonging to a certain transaction, there are a plurality of logs generated by the client terminal and logs generated by the Web server and the AP server, and the cause investigation can be performed by combining a plurality of logs corresponding to the transaction ID. Done.

  Since the complaint that the processing time is long is that the total processing time described above is long, the person in charge such as the developer of the Web system firstly, from the huge log, “the total processing time is a certain time or more” One or more logs that satisfy the condition are searched. Next, the log including the drawing time is searched using the transaction ID of the corresponding log as a key. Based on experience, it is determined whether the physical location of the problem is on the client side or the server side (Web server, AP server, etc.) while comparing the total processing time corresponding to one transaction ID and the drawing time. To do.

  For example, if the ratio of the drawing time to the total processing time is large, the client terminal is likely to have a problem. If the ratio of the drawing time to the total processing time is small, the Web server or the AP server is likely to have a problem. . If it is determined that there is a problem on the server side, the person in charge analyzes the other logs on the server side corresponding to the transaction ID in detail.

  However, the total processing time includes not only the application execution time in the AP server and the drawing time in the client terminal, but also the generation time of screen drawing information in the Web server, the communication time between the Web server and the AP server, and the like.

  Since the generation time of the screen drawing information is a processing time outside the range that can be improved by the person in charge, the ratio of the drawing time to the total processing time indicates that communication failure, Web server, AP server, client terminal It has been found that it is effective to evaluate the software or hardware failure except for the generation time of the screen drawing information.

  In other words, it is desirable that the generation time of the screen drawing information is preferably determined by comparing the remaining time obtained by excluding the generation time from the total processing time with the drawing time. Therefore, the person in charge needs to search another log on the server side and acquire the generation time of the screen drawing information.

  However, since an actual Web system includes a large number of client terminals, and a large number of transactions are executed per day based on processing requests from the client terminals, the amount of accumulated logs becomes enormous. . For this reason, it takes a lot of time to analyze the server-side log in detail in order to accurately identify the physical location of the problem.

  An object of the present invention is to provide log information that can accurately determine whether the physical location of a problem is on the client side or the server side in a shorter time when the total processing time of the transaction is long. is there.

The information processing apparatus includes a communication unit, a processing result acquisition unit, a generation unit, a measurement unit, and a log processing unit.
The communication means communicates with the terminal, the processing server, and the log server. The processing result acquisition unit assigns processing identification information to the first processing request received from the terminal and requests execution of the processing, and processes based on the processing identification information and the first processing request via the communication unit. Is sent to the processing server. Then, the processing identification information and the processing result for the second processing request are received from the processing server.

The generating unit generates screen drawing information from the processing result, and the measuring unit measures a generation time required for generating the screen drawing information.
The log processing unit transmits the processing identification information, the screen drawing information, and the generation time to the terminal via the communication unit. Then, the processing identification information, the generation time, the drawing time required for drawing the screen based on the screen drawing information in the terminal, and the total processing time from when the first processing request is transmitted until the drawing of the screen is finished are Receive from. The log processing means transmits log information including information relating to the processing identification information, generation time, drawing time, and total processing time to a log server that manages the log information.

  According to the information processing apparatus described above, the log server stores log information including not only the total processing time and drawing time but also the generation time required to generate screen drawing information from the processing result. In this case, if the person in charge searches for a log corresponding to the condition that “the total processing time is equal to or longer than a certain time”, the person in charge can see the log information in which the total processing time, the drawing time, and the generation time are combined. Then, if the remaining time excluding the generation time from the total processing time is compared with the drawing time, the processing time required for processing other than the generation of the screen drawing information and the drawing of the screen can be compared with the drawing time in the terminal. it can. Thereby, it is possible to accurately determine whether the physical location of the problem is on the client side or the server side in a shorter time based on one log information.

Hereinafter, embodiments will be described in detail with reference to the drawings.
FIG. 1 illustrates a functional configuration example of the information processing apparatus according to the embodiment. The information processing apparatus 101 in FIG. 1 includes a measurement unit 111, a processing result acquisition unit 112, a generation unit 113, a log processing unit 114, and a communication unit 115. The communication unit 115 communicates with a terminal, a processing server, and a log server via a communication network.

  FIG. 2 is a flowchart of log processing by the information processing apparatus 101 of FIG. First, the communication unit 115 receives a first processing request from the terminal (step 201). The processing result acquisition unit 112 adds processing identification information to the first processing request, and transmits the processing identification information and the second processing request based on the first processing request to the processing server via the communication unit 115. (Step 202). Then, the communication unit 115 receives the processing identification information and the processing result for the second processing request from the processing server (step 203).

The generation unit 113 generates screen drawing information from the processing result (step 204), and the measurement unit 111 measures the generation time required for generating the screen drawing information (step 205).
The log processing unit 114 transmits processing identification information, screen drawing information, and generation time to the terminal via the communication unit 115 (step 206). The communication unit 115 performs processing identification information, generation time, drawing time required for drawing the screen based on the screen drawing information in the terminal, and total processing time from when the first processing request is transmitted until drawing of the screen is completed. Is received from the terminal (step 207). The log processing unit 114 transmits log information including information regarding the processing identification information, generation time, drawing time, and total processing time to the log server via the communication unit 115 (step 208).

  According to such an information processing apparatus, the log server stores log information including not only the total processing time and drawing time but also the generation time required to generate the screen drawing information from the processing result. In this case, if the person in charge searches for a log corresponding to the condition that “the total processing time is equal to or longer than a certain time”, the person in charge can see the log information in which the total processing time, the drawing time, and the generation time are combined.

  Then, if the remaining time excluding the generation time from the total processing time is compared with the drawing time, the processing time required for processing other than the generation of the screen drawing information and the drawing of the screen can be compared with the drawing time in the terminal. it can. Thereby, it is possible to accurately determine whether the physical location of the problem is on the client side or the server side in a shorter time based on one log information.

  FIG. 3 shows a configuration example of a Web system using the information processing apparatus of FIG. 1 as a Web server. 3 includes a client terminal 301, a Web server 302, an AP server 303, a database server (DB) server 304, and a log server 305. The client terminal 301 and the servers 302 to 305 can communicate with each other via a communication network such as the Internet or an intranet.

  The Web system of FIG. 3 includes one client terminal 301, but the number of client terminals included in the Web system of the embodiment may be two or more. When the AP server 303 does not make an inquiry to the DB server 304, the DB server 304 can be omitted.

  FIG. 4 shows a functional configuration example of the Web server 302 of FIG. 3 includes a measurement unit 411, a generation unit 412, a storage unit 413, a control unit 414, and a communication unit 415.

  The measurement unit 411, the generation unit 412, and the communication unit 415 correspond to the measurement unit 111, the generation unit 113, and the communication unit 115 in FIG. 1, respectively. The control unit 414 includes the processing result acquisition unit 112 and the log process in FIG. Corresponds to the section 114. The storage unit 413 stores various types of information including session information 421, time information 422, processing results 423, screen drawing information 424, and log information 425 as the transaction progresses.

  In the session information 421, a transaction ID is recorded as identification information for identifying the session of the client terminal 301, and in the time information 422, a time when a predetermined process is performed in the Web server 302 is recorded. The processing result 423 corresponds to the processing result received from the AP server 303, and the screen drawing information 424 is information used to draw a screen showing the processing result 423 in the client terminal 301. Log information 425 corresponds to log information received from the client terminal 301.

  The screen rendering information 424 includes, for example, data indicating the processing result 423 and a program for rendering a screen including the data, such as JavaServer Pages (“Java” is a registered trademark). For example, HyperText Markup Language Described in an (HTML) file.

  FIG. 5 shows a plurality of processing times in the Web system of FIG. The client terminal 301 transmits a request to the Web server 302 (procedure 501). This initiates a transaction. The Web server 302 transmits a request based on the received request to the AP server 303 (procedure 502).

  The AP server 303 performs business processing by executing an application based on the received request. At this time, if a DB inquiry is included in the application, a DB request is transmitted to the DB server 304 (step 503). The DB server 304 executes DB processing based on the received DB request, and returns the processing result of the DB processing to the AP server 303 (procedure 504).

  The AP server 303 continues the business process using the received processing result, and returns the business process result to the Web server 302 (step 505). The Web server 302 generates screen drawing information 424 using the received processing result, and transmits the screen drawing information 424 to the client terminal 301 (procedure 506). The client terminal 301 draws a screen using the received screen drawing information 424 and displays it on the display device. The transaction ends when the screen is displayed on the display device. However, the Web server 302 may determine that the transaction has ended when it returns the processing result to the client terminal 301 and may notify the log server 305 of the end of the transaction.

In such a transaction, the total processing time T1, the business execution time T2, the AP server processing time T3, the generation time T4, and the drawing time T5 are defined as follows.
Total processing time T1: This is the time from when the client terminal 301 sends a request to the Web server 302 until the end of screen drawing on the client terminal 301.

Business execution time T2: This is the time from when the Web server 302 sends a request to the AP server 303 until the processing result is received from the AP server 303.
AP server processing time T3: This is the time from when the AP server 303 receives a request from the Web server 302 until the processing result is transmitted to the Web server 302.

Generation time T4: This is the time from when the Web server 302 starts generating the screen drawing information 424 until the generation ends.
Drawing time T5: This is the time from when the client terminal 301 receives the screen drawing information 424 from the Web server 302 until the drawing of the screen ends.

  When the drawing of the screen is completed, the client terminal 301 transmits log information 425 including the total processing time T1, the generation time T4, and the drawing time T5 to the Web server 302, and the Web server 302 transmits the log information 425 to the log server. To 305. Thus, the log information 425 is recorded in the log server 305.

  6A and 6B show examples of a plurality of log information recorded in the log server 305. FIG. Each log information includes a transaction ID, server type, server Internet protocol (IP) address, screen ID, log name, user ID, affiliation code, date, time, client IP address, numeric values 1 to 3, and action name. Including.

  The server type represents the type of the server that transmitted the log information to the log server 305, and “W3” and “AP” represent the Web server and the AP server, respectively. The screen ID is identification information corresponding to the application executed by the AP server 303, and the log name is the name of the log information. The user ID corresponds to the user of the client terminal 301, and the affiliation code represents a group to which the user belongs. The date and time represent the date and time when the log information is recorded in the log server 305, and the numerical values 1 to 3 represent the processing time corresponding to the log name. The action name is a character string indicating the contents of the transaction.

  The log name includes AP server processing time, business execution time, and screen processing time. When the log name is “AP server processing time”, the AP server processing time T3 is described as a numerical value 1, and when the log name is “business execution time”, the business execution time T2 is described as a numerical value 1. When the log name is “screen processing time”, the total processing time T1, the generation time T4, and the drawing time T5 are described in the numerical value 1, the numerical value 2, and the numerical value 3, respectively. When the log name is “AP server processing time” or “business execution time”, the numerical values 2 and 3 are not used and thus remain “0”.

  The server types of the log information 601, 603, 604, 606, 607, 609, and 610 are “W3”, which indicates that the log information is received from the Web server 302. On the other hand, the server type of the log information 602, 605, and 608 is “AP”, which indicates that the log information is received from the AP server 303.

  The log name of the log information 602 is “AP server processing time”, and the numerical value 1 describes “16” as the AP server processing time T3. In this example, the unit of time is milliseconds. The log name of the log information 603 is “business execution time”, and the numerical value 1 describes “31” as the business execution time T2.

  Further, the log name of the log information 610 is “screen processing time”, “2203” is described as the total processing time T1 in the numerical value 1, and the generation time T4 and the drawing time are described in the numerical values 2 and 3. “16” and “1422” are respectively described as T5. First, when the generation time T4 is subtracted from the total processing time T1, the remaining time is “2187”. By comparing this “2187” with the rendering time “1422”, the person in charge can empirically determine whether the physical problem is in the client terminal, the Web server or the AP server. it can. Here, for example, when it is determined that the drawing time is not large with respect to the time obtained by excluding the generation time from the total processing time, the person in charge details the logs generated by the AP server 303 and the Web server 302. Analyze and identify the location of physical problems.

  If the generation time T4 and the drawing time T5 are subtracted from the total processing time T1, the remaining time becomes “765”. The remaining time includes not only the job execution time T2 but also various other things in the Web system. Processing time is included.

According to the log information of FIGS. 6A and 6B, the person in charge can recognize the following possibility as a cause of the long total processing time T1.
For example, if the AP server processing time T3 is long, there is a possibility that the application execution in the AP server 303 or the inquiry to the DB server 304 is a bottleneck. Further, if the business execution time T2 is long even though the AP server processing time T3 is short, it may be caused by communication deterioration between the Web server 302 and the AP server 303 or insufficient multiplicity of the AP server 303. On the other hand, if the generation time T4 is long, there is a possibility that the amount of data displayed on the screen is too large or the resources of the Web server 302 are exhausted. Further, if the drawing time T5 is long, the performance of the client terminal 301 may be a bottleneck.

  The end of the transaction ID of the log information 610 is “000033A1-F”, which is partly different from “0000301-F”, which is the end of the transaction ID of the log information 602 and 603. However, these transaction IDs do not indicate different transactions, but indicate the same transaction. In this case, since portions other than “A1” and “01” which are different character strings are the same, it can be recognized that the log information belongs to the same transaction.

  The log information according to the embodiment does not need to include all items illustrated in FIGS. 6A and 6B, and some items may be omitted depending on the configuration and conditions of the Web system. For example, when the screen ID and the action name are unnecessary, these items may be omitted.

  FIG. 7 shows an example of the time information 422 of FIG. The time information 422 in FIG. 7 includes a business process start time 701 and a generation start time 702. The business process start time 701 is a time when the Web server 302 starts a business process by transmitting a request to the AP server 303, and the generation start time 702 is a time when the generation of the screen drawing information 424 is started. The business process start time 701 and the generation start time 702 are recorded by the measuring unit 411 and are used for measuring the business execution time T2 and the generation time T4, respectively.

  8 and 9 show a transaction execution procedure in the Web system of FIG. In the following description, unless otherwise specified, the operation of the Web server 302 is performed by the control unit 414 or the communication unit 415.

  First, the user of the client terminal 301 performs screen operations such as button pressing and screen transition on the displayed screen (step 801 in FIG. 8). At this time, the client terminal 301 acquires the current time from the timer and sets it as a hidden item on the screen as the action start time. The hidden item is set as information on the screen, but is treated as non-display. The client terminal 301 further sets the action name of the transaction to be executed as a hidden item, and transmits a request to the Web server 302 (step 802). This request includes the action start time, action name, user ID, and affiliation code.

  When receiving the request, the Web server 302 determines whether to transmit log information to the log server 305 (step 803). For example, if the received request already includes a transaction ID, it is determined that log information is to be transmitted. Since the transaction ID is not included in the first request, log information is not transmitted.

  Next, the Web server 302 analyzes the content of the request and performs preprocessing for the request to the AP server 303. The measuring unit 411 acquires the current time from the timer and records it in the time information 422 as the business process start time 701.

  The Web server 302 gives a transaction ID to the received request and records the transaction ID in the session information 421. Then, a transaction start notification including the transaction ID, server type, user ID, and affiliation code is transmitted to the log server 305 (step 804). When the log server 305 receives the transaction start notification, the log server 305 generates log header information including a transaction ID, a server type, a user ID, and an affiliation code (step 805). At this time, “W3” is recorded as the server type.

Next, the Web server 302 transmits a request including the transaction ID and identification information of the application to be executed to the AP server 303 (step 806).
Upon receiving the request, the AP server 303 acquires the current time from the timer and records it as the AP server processing start time (step 807). Then, a process start notification including the transaction ID and server type is transmitted to the log server 305 (step 808). Upon receiving the processing start notification, the log server 305 updates the server type of the log header information from “W3” to “AP” (step 809).

  Next, the AP server 303 performs business processing by executing an application based on the received request, and generates a processing result of the business processing (step 810). Then, the current time is acquired from the timer, and is used as the AP server process end time, and the AP server process start time is subtracted from the AP server process end time to obtain the AP server process time T3.

  Next, the AP server 303 transmits log information including the transaction ID, server type, log name, and AP server processing time T3 to the log server 305 (step 811). Upon receiving the log information, the log server 305 records it as log information of the AP server 303 together with log header information (step 812). At this time, “AP server processing time” is used as the log name, and for example, log information such as log information 602 in FIGS. 6A and 6B is recorded.

  Next, the AP server 303 transmits a process end notification including the transaction ID to the log server 305 (step 813). Upon receiving the processing end notification, the log server 305 updates the server type of the log header information from “AP” to “W3” (step 814).

  Next, the AP server 303 returns the transaction ID and the processing result of the business process to the Web server 302 (step 815). The Web server 302 stores the received business process result in the storage unit 413 as the process result 423, and analyzes the data included in the process result 423 (step 816). The measuring unit 411 obtains the business execution time T2 by acquiring the current time from the timer, using it as the business process end time, and subtracting the business process start time 701 from the business process end time.

  Next, the Web server 302 transmits log information including the transaction ID, server type, log name, and business execution time T2 to the log server 305 (step 817). When receiving the log information, the log server 305 records it as log information of the Web server 302 together with the log header information (step 818). At this time, “business execution time” is used as the log name, and for example, log information such as the log information 603 in FIGS. 6A and 6B is recorded.

  Next, the Web server 302 transmits a transaction end notification including the transaction ID to the log server 305 (step 819). When the log server 305 receives the transaction end notification, the log server 305 deletes the log header information (step 820).

  Next, the Web server 302 performs post-processing of a request to the AP server 303. The generation unit 412 starts a process of generating the screen drawing information 424 using the processing result of the business process (Step 901 in FIG. 9). At this time, the measurement unit 411 acquires the current time from the timer and records it in the time information 422 as the generation start time 702.

  In the generation process of the screen drawing information 424, the generation unit 412 sets the action start time and the action name included in the request from the client terminal 301 as hidden items on the screen. Further, the transaction ID of the session information 421 is set as a hidden item on the screen, and the transaction ID is deleted from the session information 421. Then, data included in the processing result of the business process is set in the screen drawing information 424.

  Next, the measurement unit 411 obtains the generation time T4 by acquiring the current time from the timer, using it as the generation end time, and subtracting the generation start time 702 from the generation end time. The generation unit 412 sets the generation time T5 as a hidden item on the screen, and the Web server 302 returns the generated screen drawing information 424 to the client terminal 301 (step 902). The screen drawing information 424 includes an action start time, an action name, a transaction ID, and a generation time T4.

  Upon receiving the screen drawing information 424 (step 903), the client terminal 301 starts drawing the screen using the screen drawing information 424 (step 904). At this time, the current time is acquired from the timer and recorded as the drawing start time.

  Next, when the drawing on the screen is finished, the current time is acquired from the timer, and the drawing time T5 is obtained by subtracting the drawing start time from the drawing end time using the current time as the drawing end time. Then, the drawing time T5 is set as a hidden item on the screen.

  Next, the total processing time T1 is obtained by subtracting the action start time from the drawing end time, and the total processing time T1 and the generation time T4 included in the screen drawing information 424 are set as hidden items on the screen.

  Thereafter, when the user performs the next screen operation on the screen displayed on the display device, the client terminal 301 performs the same processing as steps 801 and 802 (steps 905 and 906). However, the request transmitted to the Web server 302 in step 906 includes the action name and transaction ID of the screen drawing information 424 received in step 903, the total processing time T1, the generation time T4, and the drawing time T5. This request further includes the action start time, action name, user ID, and affiliation code of a new action.

  When receiving the request, the Web server 302 determines whether to transmit log information to the log server 305 (step 907). Here, since the received request includes a transaction ID, it is determined to transmit log information.

  Therefore, the Web server 302 acquires the action name, transaction ID, total processing time T1, generation time T4, and drawing time T5 of the previous action from the received request. Then, as shown in the log information 610 in FIGS. 6A and 6B, a part of the transaction ID character string is modified, and a transaction start notification including the modified transaction ID, server type, user ID, and affiliation code is logged. The data is transmitted to the server 305 (step 908). The transaction ID is modified based on a preset rule. For example, the Web server 302 changes the last two digits of the transaction ID from “01” to “A1”. By changing the transaction ID, the log server can be prevented from receiving the log information including the deleted transaction ID again after deleting the log header information in step 820.

  Upon receiving the transaction start notification, the log server 305 generates log header information including the modified transaction ID, server type, user ID, and affiliation code (step 909). At this time, “W3” is recorded as the server type.

  Next, the Web server 302 generates log information 425 including the modified transaction ID, server type, log name, total processing time T1, generation time T4, drawing time T5, and action name, and stores it in the storage unit 413. Store. Then, the log information 425 is transmitted to the log server 305 (step 910).
