Description

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

  The information processing apparatus has a function of recording the execution status of the process in a log in order to prepare for the cause investigation when a failure occurs. The execution status recorded in the log has several levels of different importance from the occurrence of a serious failure to a detailed program execution status for debugging or the like. This level is called the log level. If all the log level information is recorded, the amount of log data becomes enormous. Therefore, it is general to record only information of a set log level or higher. Further, when an abnormality occurs in the information processing apparatus, more detailed information is recorded in the log by automatically lowering the log level setting.

  The apparatus disclosed in Patent Document 1 monitors state values such as free space in a memory area, CPU operating rate, system temperature, and the like, and determines whether the system is normal or abnormal from the monitored state values. If the system determines that there is an abnormality, the log level is lowered so that a log with low importance (that is, more detailed) is recorded.

  The log output device disclosed in Patent Document 2 records a log necessary for investigating the cause of an error even when an error occurs when the system is determined to be normal from the status value of the monitored system. The purpose is to do so. This apparatus detects the frequency of occurrence of logs generated by modules to be monitored, and lowers the log level as the detected frequency increases, so that more detailed logs are output.

  Patent Document 3 discloses a mechanism for collectively changing log levels of a plurality of servers in a system that provides services to clients by a plurality of servers. In this mechanism, when a log level change command is sent to one of the servers from the operator's terminal that manages the log level, the server changes the log level according to the command and Similarly, a log change message indicating that the log level should be changed is broadcast. Each server that receives this message changes the log level according to the message.

  With reference to FIG. 1, an example of a system configuration according to an embodiment of the present invention will be described. This system includes a service providing apparatus 100 and one or more client apparatuses 200 that receive services from the service providing apparatus 100 via a network 300.

  The service providing apparatus 100 is not particularly limited to the service provided to the client apparatus 200. As an example, there is a VPN (Virtual Private Network) connection service illustrated in FIG. A VPN connection service is used when a user makes a VPN connection from a client device such as a mobile terminal to an in-house LAN. The VPN gateway 150 illustrated in FIG. 2 is an example of the service providing apparatus 100 in FIG. The VPN gateway 150 provides a service for connecting a plurality of client devices 200-1, 200-2, 200-3,... On the Internet 310 to a company LAN (local area network) 400 of a specific company via VPN. provide. Each client device 200 has a VPN client 250 (software) installed. The client device 200 can make a VPN connection to the in-house LAN 400 in cooperation with the VPN client 250 and the VPN gateway 150. Each element (function) in the client apparatus 200 in FIG. 1 is incorporated in the VPN client 250.

  Returning to the description of FIG. The service providing apparatus 100 includes a log recording unit 102, a log level changing unit 104, a change instruction transmitting unit 106, and a change instruction receiving unit 108.

  The log recording unit 102 records log information about processing executed by the service providing apparatus 100 (that is, service providing processing via communication with each client device 200). The log information may be recorded in a storage device in the service providing apparatus 100 or may be output to a log totaling apparatus on the network. The log recording unit 102 records log information about processing for providing a service to the client device 200 in a form that can be distinguished for each client device 200 of the communication partner. Further, the log recording unit 102 holds a log level individually for each client device 200 of the communication partner, and a level equal to or higher than the log level for the client device 200 in the process for providing a service to the client device 200 Only log information (that is, importance level or higher corresponding to the log level) is recorded. As is well known, the log level is a value that defines the granularity of the log information to be recorded (in other words, the event that occurred during processing represented by the log information), and the higher the log level value, the more the log information to be recorded. Becomes coarser (ie, only the more important events are recorded).

  The log level changing unit 104 performs processing for changing the log level value referred to by the log recording unit 102.

  The log level change is, for example, an event that satisfies the condition for changing the log level in the process for providing a service to the client device 200 executed by the service providing apparatus 100 (for example, as in the past) (for example, This is done when something abnormal) is detected. Such an event is hereinafter also referred to as a “trigger”.

  What is used as a trigger may be the same as in the past. For example, frequent disconnection of the connection between the client device 200 and the service providing device 100 (for example, a predetermined threshold number of times within a predetermined length of time) is one trigger. Further, the failure of authentication when the client device 200 tries to receive a service from the service providing device 100 can be another trigger. Further, when the authentication process is divided into several steps, the failure may be handled as a separate trigger for each step where the authentication fails. Further, instead of immediately determining a trigger with a single authentication failure, it may be determined as a trigger when a predetermined threshold number of times have failed. Thus, when a reproducible abnormality is detected, it may be determined as a trigger.

  Also, the log level changing condition may be the same as the conventional one. For example, the condition is that the log level is lowered to a certain level when a certain trigger is detected, and the log level is lowered to another certain level when another trigger is detected. When an event (trigger) that satisfies a log level change condition occurs in a process with a certain client device 200, the log level changing unit 104 changes the log level for the client device 200 to a level corresponding to the event. To do.

  As another case of changing the log level, there is a case where a log level change instruction is received from the client device 200. As will be described later, since the log level change instruction includes specific information for specifying the log level of the change destination, in this case, according to the specific information included in the received log level change instruction, the client that has transmitted the change instruction Change the log level for the device 200. If the specific information indicates the log level value itself of the change destination, it can be changed to that value. If the specific information indicates a trigger that triggered the transmission of the log level change instruction, The log level corresponding to the trigger may be obtained and changed to the obtained log level.

  The change instruction transmission unit 106 transmits a log level change instruction to the client device 200. When the log level changing unit 104 detects an event (trigger) that satisfies the log level changing condition in the process for providing a service to the client device 200, the change instruction transmitting unit 106 sends the change to the client device 200. In response, a log level change instruction is transmitted. The log level change instruction includes specific information for specifying the change destination log level corresponding to the trigger. This specific information may represent the value of the change destination log level, or may be identification information of the trigger. In the latter case, the client device 200 that has received the specifying information may specify the log level of the change destination from the correspondence between the trigger and the log level.

  The change instruction receiving unit 108 receives a log level change instruction from the client device 200. The received log level change instruction is transmitted to the log level changing unit 104 together with the identification information of the client apparatus 200 of the change instruction. The log level changing unit 104 changes the log level value for the client device 200 indicated by the identification information referred to by the log recording unit 102 in accordance with the log level changing instruction.

  As described above, in the example of FIG. 1, the service providing apparatus 100 and the client apparatus 200 that are advancing the process while communicating with each other are events (triggers) that satisfy the log level change condition in the process of the own apparatus. When this happens, they are informed of each other.

  However, informing each other, that is, sending log level change instructions to each other is merely an example, and log level change instructions may be sent only from one of the service providing apparatus 100 or the client apparatus 200 to the other.

  The client device 200 includes a log recording unit 202, a log level changing unit 204, a change instruction transmitting unit 206, and a change instruction receiving unit 208.

  The log recording unit 202 records log information about processing for the client device 200 to receive a service (for example, VPN connection) from the service providing device 100 via communication. The log information may be recorded in a storage device in the client device 200 or may be output to a log totaling device on the network (for example, this may be the service providing device 100). May be. The log recording unit 202 holds a log level, and only logs information about an event of a level higher than the log level (that is, an importance higher than the importance corresponding to the log level) generated in the processing. Record.

  The log level changing unit 204 performs processing for changing the value of the log level referred to by the log recording unit 202. The log level changing unit 204 is performed when a trigger event satisfying the log level changing condition is detected in the process for receiving a service from the service providing apparatus 100 as in the conventional case. The condition for changing the log level may be the same as in the past. When the change instruction receiving unit 208 receives a log level change instruction from the service providing apparatus 100, the log level changing unit 204 may change the log level according to the change instruction. As described above, since the log level change instruction includes specific information for specifying the log level of the change destination, the log level value of the change destination is determined from the specific information in the log level change instruction received by the change instruction receiving unit 208. And change the log level to the specified value. If the specific information indicates the value of the log level of the change destination itself, it should be changed to that value. If the specific information indicates the trigger that triggered the transmission of the log level change instruction, A log level corresponding to the trigger may be obtained and changed to the obtained log level.

  The change instruction transmission unit 206 transmits a log level change instruction to the service providing apparatus 100. When the log level changing unit 204 detects a trigger in the process for receiving a service from the service providing apparatus 100, the change instruction transmitting unit 206 transmits a log level changing instruction to the service providing apparatus 100. The log level change instruction includes specific information for specifying the change destination log level corresponding to the trigger. This specific information may represent the value of the change destination log level, or may be identification information of the trigger.

  The change instruction receiving unit 208 receives a log level change instruction from the service providing apparatus 100. The received log level change instruction is transmitted to the log level change unit 204. The log level changing unit 204 changes the value of the log level referred to by the log recording unit 202 according to the log level changing instruction.

  Next, a specific example of the flow of processing in the present embodiment will be described with reference to FIG. In the example of FIG. 3, when the client device 200 detects an event (trigger) that satisfies a log level change condition in a process for receiving a service from the service providing device 100 (S202), the log recording unit 202 refers to the event. The log level is changed to a value corresponding to the trigger (S204), and a log level change instruction for instructing a change to the log level corresponding to the trigger is transmitted to the service providing apparatus 100 (S206).

  When the service providing apparatus 100 receives the log level change instruction from the client apparatus 200 (S102), the service providing apparatus 100 specifies the log level change destination value from the information (the aforementioned specific information) in the log level change instruction, and the log recording unit The log level value of the client device 200 referred to by 202 is changed to the change destination value (S104).

  As described above, in this embodiment, when the service providing apparatus 100 or the client apparatus 200 communicating with each other detects a trigger event that satisfies the log level change condition in the process of the own apparatus, the log recording unit in the own apparatus While changing the log level of 102 or 202, a log level change instruction is sent to the client apparatus 200 or the service providing apparatus 100 of the communication partner. Thus, when the log level is changed in one device, the log level is also changed in the communication counterpart device accordingly.

  As described above, in this embodiment, the service providing apparatus 100 and the client apparatus 200 change the log level in conjunction with each other. This means that the log level of the client apparatus 200 and the client in the service providing apparatus 100 are changed. It does not necessarily mean that the log level of the device 200 is linked to “the same value”. The log level leveling system may be different between the service providing apparatus 100 and the client apparatus 200. In such a case, the log levels in both apparatuses may not be the same value. However, even in such a case, the log level of the client apparatus 200 and the log level of the client apparatus 200 in the service providing apparatus 100 become “corresponding” values due to the interlocking by the log level change instruction. Even when a log level change instruction is received from the client apparatus 200, the log level for the client apparatus 200 in the service providing apparatus 100 may be a value corresponding to the log level change instruction. It is not necessary to change the log level.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  In the second embodiment, when the service providing apparatus 100 receives a log level change instruction from any of the client apparatuses 200, the service providing apparatus uses the “corresponding communication environment” as the communication environment of the client apparatus 200. An instruction to change the log level is sent to another client device 200 communicating with the client 100. That is, the log level change is propagated to the same type of client device 200.

  The “communication environment” of the client device 200 here refers to various resources used for the client device 200 to communicate with the service providing device 100. The communication environment includes, for example, the type of connection line used by the client device 200 to connect to the Internet, the ISP (Internet service provider), and the type of LAN to which the client device 200 is connected (for example, connected wireless). LAN standards), the IP address of the client device 200, and the like. If the IP address is known, the Internet connection line or ISP may be identified. In addition, a platform serving as a basis for executing a processing program (a VPN client in the example of FIG. 2) for the client device 200 to receive a service from the service providing device 100, such as an OS (operating system) program, is an example of a communication environment. It is. Further, hardware information used for execution of the program and communication with the service providing apparatus 100, for example, a hardware model, is an example of a communication environment. Various devices such as a personal computer, a tablet terminal, and a smartphone can be considered as the plurality of client devices 200 with which the service providing device 100 communicates.

  Each resource illustrated above is an example of a “communication environment”, and one client apparatus 200 performs processing for receiving a service from the service providing apparatus 100 using a set of one or more communication environments. Run.

  In the future, other client devices 200 having a communication environment corresponding to the communication environment of the client device 200 that is the transmission source of the log level change instruction will have the same abnormality as the transmission source client device 200 in the future (when the change instruction is transmitted) It is considered that there is a high possibility that the trigger event will occur. Therefore, in the second embodiment, the log level of another client device 200 in the communication environment corresponding to the communication environment of the client device 200 of the transmission source is changed in conjunction with the change of the log level of the transmission source. Thus, log information of a necessary log level can be recorded in advance in preparation for occurrence of a similar abnormality. When the abnormality actually occurs (although it does not necessarily occur), the client device 200 that has received the propagation of the log level change instruction analyzes the abnormality more in detail than the case where the abnormality has not been propagated. Log information that is higher than the log level that is considered necessary. If there is detailed log information recorded before the actual occurrence of the abnormality, the analysis of the abnormality becomes easy. Conventionally, after an abnormality has actually occurred in the client device 200, a user using the client device 200 contacts customer support of the service providing device 100, and the customer support changes the log level setting to the user accordingly. The client device 200 collects more detailed log information, and this is a post-mortem and manual response. In contrast, in the second embodiment, the log level can be changed in advance and automatically to collect more detailed log information.

  Here, the communication environment of one client device A “corresponds” to the communication environment of another client device B is, in one example, a case where a set of communication environments of both devices completely match. For example, this is a case where the values of the items of the communication environment such as the OS, the Internet connection line, and the provider all match between the two devices. In such a case, both communication environments may be expressed as “same”. However, this is only an example. Even when the set of communication environments of the client device B and the set of communication environments of the client device A partially match, the communication environments of both may be regarded as “corresponding”. For example, although the devices A and B use the same OS, even when the Internet connection line and the provider are different (or unknown), both of them may be “corresponding communication environments”. To determine that the “communication environment” of both devices is “corresponding”, how much of the elements in the set of communication environments need to be matched or in the order of importance The number of elements that need to be matched may be set in the service providing apparatus 100, or the setting may be changed.

  FIG. 4 shows an example of the system configuration of the second embodiment. In FIG. 4, the same elements as those shown in FIG.

  The service providing apparatus 100 in the system of FIG. 4 includes a communication environment information acquisition unit 110, a communication environment information holding unit 112, and a level change propagation processing unit 114 in addition to the elements included in the service providing apparatus 100 in the embodiment of FIG. . The client device 200 includes a communication environment information transmission unit 210 in addition to the elements included in the client device 200 of the embodiment of FIG.

  The communication environment information transmitting unit 210 of the client device 200 transmits information on the communication environment (described above) used when the client device 200 receives a service from the service providing device 100 to the service providing device 100. The communication environment information acquisition unit 110 of the service providing apparatus 100 acquires the communication environment information transmitted by the communication environment information transmission unit 210.

  The information on the communication environment exemplified above can be exchanged at the time of handshake at the start of communication or can be obtained from the information exchanged at the time of handshake. Therefore, the communication environment information transmission unit 210 and the communication environment information acquisition unit 110 may be a communication protocol handshake function implemented in the service providing apparatus 100 and the client apparatus 200.

  The communication environment information holding unit 112 of the service providing apparatus 100 holds information on the communication environment of each client apparatus 200. An example of information held by the communication environment information holding unit 112 is shown in FIG. In the example of FIG. 5, the communication environment information holding unit 112 is associated with “client ID” which is identification information of each client device 200 assigned by the service providing device 100, and “OS”, “Internet connection line”, “ Each communication environment item value such as “provider”, “IP address”, and “hardware information” is held. The items shown in the figure are merely examples. The communication environment information holding unit 112 need not hold all of the illustrated items, and may hold items other than the illustrated items. In addition, in each item held by the communication environment information, in addition to the information transmitted from the client device 200 (communication environment information transmission unit 210), a communication path between the client device 200 and the service providing device 100 Information added by any one of the above nodes (for example, ISP) or information obtained from the information may be included. For example, the ISP used by the client device 200 may be identified from the IP address acquired from the client device 200, and the identification name of the ISP may be registered in the communication environment information holding unit 112 as one of the communication environments. .

  When the change instruction receiving unit 108 receives a log level change instruction from any of the client devices 200, the level change propagation processing unit 114 refers to the communication environment information holding unit 112 and sets the communication environment of the client device 200 to “ Another client device 200 having a “corresponding communication environment” is identified. Then, for each of the other client devices 200 of the specified “corresponding communication environment”, the instruction for changing to the log level corresponding to the log level of the change destination specified by the log level change instruction is given. Send log level change instruction.

  The transmitted propagation log level change instruction is received by the change instruction receiving unit 208 of the destination client device 200. Then, the log level changing unit 204 changes the log level of the client device 200 according to the change instruction.

  A specific example of the processing flow in the second embodiment will be described with reference to FIG. Of the steps shown in FIG. 6, the same steps as those in the procedure shown in FIG.

  In the procedure of FIG. 6, first, during a handshake process when a certain client device 200-1 starts communication with the service providing device 100, the communication environment information transmission unit 210 of the client device 200-1 Information is transmitted (S200). The communication environment information acquisition unit 110 of the service providing apparatus 100. The communication environment information of the client device 200-1 including the transmitted information is acquired (S100).

  Thereafter, the client apparatus 200-1 detects a trigger event that satisfies the log level change condition (S202), transmits a log level change instruction corresponding to the trigger (S206), and the service providing apparatus 100 receives the change instruction. (S102). In response to this, the service providing apparatus 100 changes the log level of the client apparatus 200-1 in its own apparatus according to the change instruction (S104), and “corresponding communication environment to the communication environment of the client apparatus 200-1”. The log level change instruction propagation process (S106 to S110) to other client apparatuses (for example, the client apparatus 200-2 shown in the figure) communicating with the service providing apparatus 100 is performed.

  That is, first, the level change propagation processing unit 114 of the service providing apparatus 100 obtains the communication environment of the client device 200-1 by referring to the communication environment information holding unit 112, and communicates in the communication environment corresponding to the communication environment. The other client device 200 performing the process is extracted (S106). Here, for example, among the items of each communication environment held in the communication environment information holding unit 112, the values of one or more items selected as considerations in advance in the setting of the service providing apparatus 100 are the client apparatus 200-1. Other client devices 200 that match are obtained. For example, in the client apparatus 200-2, the communication environment registered in the communication environment information holding unit 112 of the service providing apparatus 100 at the time of handshake (not shown) “corresponds” to the communication environment of the client apparatus 200-1. And is extracted in S106.

  Then, the log level changing unit 104 determines the log level for each client device 200 extracted in S106 among the log levels for each client device 200 referred to by the log recording unit 102 in accordance with the log level changing instruction acquired in S102. The log level is changed to the specified change destination log level (S108). Further, the level change propagation processing unit 114 transmits a log level change instruction including specific information for specifying the change destination log level to each client device 200 extracted in S106 (S110).

  Upon receiving the log level change instruction transmitted in S110 (S302), the client apparatus 200-2 specifies the log level of the change destination from the specific information included in the log level change instruction, and changes the log level of the own apparatus. The log level is changed to the previous log level (S304).

  In the example described above with reference to FIG. 6, the log level of the client device 200-1 that has transmitted the log level change instruction and the client device 200-2 of “corresponding communication environment” are changed. Although the log level specified by the instruction is changed to the same level (S108, S110, S304), it is not always necessary to change to the same level. Since the same abnormality as the client apparatus 200-1 has not yet occurred in the client apparatus 200-2 of “corresponding communication environment”, the log level of the change destination corresponding to the log level change instruction transmitted by the client apparatus 200-1 However, it is also possible to reduce the degree of change. For example, in the client device 200-1 in which an abnormality has occurred, the log level is changed from, for example, the normal value “5” (recording only the most important event) out of 5 levels to “2” (recording up to a relatively minor event). On the other hand, the log level may be changed to “3” in the other client device 200-2 to which this change is propagated.

  In the procedure shown in FIG. 6, only when a log level change instruction is received from one client apparatus 200, the change instruction is propagated to another client apparatus 200 corresponding to the communication environment. However, this may be too sensitive. Therefore, as a modification thereof, the log level change instruction is propagated to the other client devices 200 of the “corresponding communication environment” only after receiving the log level change instructions from the client devices 200 of several “corresponding communication environments”. May be.

  7A and 7B show an example of the processing procedure of the level change propagation processing unit 114 in this modification. FIG. 7A shows a process of counting log level change instruction information coming from the client device 200 group, and FIG. 7B shows an example of a process of propagating a log level change instruction based on the information obtained by the calculation. .

  In this example, the log level change instruction issued by the client device 200 includes the identification information of the trigger that triggered the change instruction. Further, the level change propagation processing unit 114 prepares a database for aggregation for each trigger. The database for one trigger has a counter for each possible value of each communication environment item. For example, when the communication environment item “Internet connection line” can take three values of “Company A optical line”, “Company B 3G line”, and “C company LTE line”, each of the three values. Has a counter.

  As shown in FIG. 7A, when the level change propagation processing unit 114 receives a log level change instruction from the client device 200 (S402), the log level for the client device 200 referred to by the log recording unit 102 is used as the change instruction. In response to the change (S404), the communication environment information of the client device 200 is reflected in the database corresponding to the trigger included in the log level change instruction (S406). That is, in S406, the counter value for each communication environment of the client device 200 out of the counters for each value that can be taken by each communication environment in the database is incremented by one. In this way, the results of the communication environment in which the trigger event has occurred are tabulated.

  Further, the level change propagation processing unit 114 executes the processing of FIG. 7B periodically, for example, in parallel with the aggregation processing of FIG. 7A. In the process of FIG. 7B, it is checked whether there is a communication environment item value whose count value is equal to or greater than a predetermined threshold value from the database corresponding to each trigger (S412). If one or more of such item values are found, the client device 200 having a communication environment corresponding to the combination of the item values is obtained from the communication environment information holding unit 112 (S414). Then, the log level for each of the client devices 200 referred to by the log recording unit 102 is changed to a log level corresponding to the trigger corresponding to the combination of the item values (S416). Further, a log level change instruction for instructing to change to the log level corresponding to the trigger is transmitted to each of the extracted client devices 200 (S418).

  For example, in S412, in the database for the trigger “second step of authentication failed”, the count value for the value “C company LTE line” of the item “Internet connection line” and the item “OS” If it is found that the count value for the value of “Android (trademark) 4.2” is equal to or greater than the threshold value, in S414, “Company C LTE line” and “Android (trademark) 4.2” Are extracted. In step S <b> 416, the log level for each extracted client device 200 referred to by the log recording unit 102 is changed to a level corresponding to the trigger “second step of authentication failed”. In step S418, a log level change instruction indicating that the level should be changed to the level corresponding to the trigger is transmitted to each of the extracted client devices 200.

  The examples in FIGS. 7A and 7B are merely examples. This modification is not unique to the individual client device 200, but to the extent that an abnormality is likely to occur in the client device 200 in general in the “corresponding communication environment” (for example, the values of the items of the communication environment match). When a number of log level change instructions are collected, the log level change instruction is propagated to other client devices 200 of the “corresponding communication environment” (having the communication environment item value). Various modifications are possible within the specified range.

  A further modification of the second embodiment will be described.

  Lowering the log level increases the amount of log information to be recorded. Therefore, when the number of client devices 200 extracted in S106 (see FIG. 6) or S414 becomes extremely large, the amount of log information to be recorded by the log recording unit 102 of the service providing device 100 becomes enormous, It may be difficult to analyze the recorded log information. In this modification, a method for dealing with such a case is proposed.

  An example of the processing procedure of the level change propagation processing unit 114 in this modification is shown in FIG. The procedure in FIG. 8 is different from the procedure in FIG. 7B in the processing after S414. In the procedure of FIG. 8, when the client device 200 corresponding to the combination of item values whose count value is equal to or greater than the threshold value is extracted in S414, it is next determined whether or not the number of extracted client devices 200 is greater than a predetermined threshold value. (S420). The log recording unit 102 can record log information at the same time if the number of clients is equal to or less than the threshold. The threshold is determined according to the log level of the change destination corresponding to the trigger. This is because if the log level changes, the details of the log information to be recorded, and hence the amount of log information, will change.

  If it is determined in S420 that the number of extracted client devices 200 is greater than the threshold value, the extracted client devices 200 are grouped into a plurality of groups in which the number of constituent members is equal to or less than the threshold value (S422). . Then, investigation is performed by changing the log level for each group (S424 to S436).

  That is, first, one survey target is selected from those groups not yet processed (S424). Then, the log level of each client device 200 in the group to be investigated, which is referred to by the log recording unit 102, is changed to a value corresponding to the trigger (S428), and each client device 200 in the group is changed to a value corresponding to the trigger. On the other hand, an instruction to change to the log level corresponding to the trigger is transmitted (S430). Then, it waits for a predetermined length of time (investigation period) to elapse (S432), and when that time elapses, the log information recorded in that period is acquired from each client device 200 of that group ( S434). The acquired log information is used for analysis. Then, it is determined whether or not the survey has been completed for all the groups created in S422 (S436), and if there is a group that has not been investigated yet, the process returns to S424. If it is determined in S420 that the number of client devices 200 extracted in S414 is equal to or smaller than the threshold value, all the extracted client devices 200 may be set as one group, and the processing in S428 and subsequent steps may be performed.

  In the second embodiment described above and the modification thereof, a single system in which one service providing apparatus 100 provides services to a plurality of client apparatuses 200 is taken as an example, and “corresponding to each other in the system” The mechanism for propagating the log level change between the client apparatuses 200 in the “communication environment” has been described.

  Here, as illustrated in FIG. 9, there may be a large system in which a plurality of systems according to the second embodiment exist, and the service providing apparatus 100 of each system is managed from a single management apparatus 500 via a network. For example, there is a case where there is a management company that provides a remote access system via VPN to the in-house LAN 400 using the VPN gateway 150 illustrated in FIG.

  In such a case, the operation status of the VPN gateway 150 installed in each organization is monitored from the management device of the management company, and if necessary, the trouble can be corrected remotely or the software can be updated. It is possible to do.

  In such a large-scale system, when a service providing apparatus 100 of a certain organization receives a log level change instruction from the client apparatus 200 in the organization, the service providing apparatus 100 informs the management apparatus 500 described above. It is also conceivable that the log level change is propagated to other service providing apparatuses via the management apparatus 500. That is, when a log level change occurs in a certain client device 200 in a system of a certain organization, the client device 200 in another organization (system) can be connected to the client device 200 in another organization (system) via the management device 500. The log level of the client device 200 of “corresponding communication environment” is changed. Hereinafter, a modified example in which the log level change is propagated to another service providing apparatus 100 and the client apparatus 200 group provided with the service by the service providing apparatus 100 through the management apparatus 500 will be described.

  In this modification, when the service providing apparatus 100 receives a log level change instruction from the client apparatus 200, the service providing apparatus 100 performs a process of transferring the log level change instruction to the management apparatus 500 in addition to the processes of the second embodiment described above. Do. At this time, the communication environment information of the client device 200 obtained from the communication environment information holding unit 112 (see FIG. 4) is transmitted to the management device 500 in association with the change instruction. Here, it is described that the log level change instruction is transferred, but this is not limited to the case where the data of the change instruction is transferred as it is. Information specifying the change content of the log level indicated by the change instruction may be transmitted. When the management apparatus 500 acquires the log level transfer instruction (or information including the same contents) and the communication environment information of the client apparatus 200 from any of the service providing apparatuses 100, the management apparatus 500 uses the information as another service providing apparatus. Forward to 100. The other service providing apparatus 100 that has received the transfer of the information performs the same processing as when receiving a log level change instruction from the client apparatus 200 of the service providing destination based on the information. That is, among the client devices 200 of the service providing destination, each client device 200 in the communication environment corresponding to the communication environment included in the transferred information is changed to the log level corresponding to the log level change instruction. Instruct.

  The service providing apparatus 100 and the client apparatus 200 exemplified above may be realized, for example, by causing a general-purpose computer to execute a program representing processing of each functional module of the apparatus. The computer referred to here includes, for example, a microprocessor such as a CPU, a memory (primary storage) such as a random access memory (RAM) and a read only memory (ROM), an HDD (hard disk drive), and an SSD (solid state drive). ), A secondary storage controller for controlling secondary storage such as a flash memory, various I / O (input / output) interfaces, a network interface for controlling connection to a wireless or wired network, etc. via, for example, a bus Connected to each other. In addition, various standards such as a disk drive and a flash memory for reading and / or writing to a portable disk recording medium such as a CD, a DVD, and a Blu-ray disk are connected to the bus via, for example, an I / O interface. A memory reader / writer for reading from and / or writing to the nonvolatile recording medium may be connected. A program in which the processing content of each functional module exemplified above is described is stored in a secondary storage device such as a flash memory via a recording medium such as a CD or DVD, or via a communication means such as a network, and the computer To be installed. The program stored in the secondary storage device is read into the RAM and executed by a microprocessor such as a CPU, thereby realizing the functional module group exemplified above.
