Description

  The present invention relates to an operation monitoring device and an operation monitoring system for monitoring the operation status of a plurality of devices connected via a network, and more specifically, a periodic connection condition for performing a periodic connection set in each device. An operation monitoring apparatus and an operation monitoring system for monitoring an apparatus and detecting an abnormality based on the periodic connection of the apparatus executed according to the above are provided.

  For example, in a conventional remote monitoring service that detects and manages a failure that occurred in a customer's device from a remote location and a failure of the monitoring notification function itself, as shown in FIG. C performs a regular connection 14 that periodically connects to the operation monitoring center 10 based on the respective operation schedules such as a 24-hour monitoring system that operates 365 days, and the operation monitoring center 10 determines whether or not the periodic connection 14 is present. By monitoring, an abnormality of the customer device is detected.

  Further, in the conventional remote monitoring service as shown in FIG. 2, the operation monitoring center 20 is periodically assigned to each device X to Z based on the monitoring schedule 21 of each device X to Z installed on the customer side. An abnormality of the customer apparatus is detected by a periodic monitor 25 that performs polling connection and monitors whether or not there is a response from each of the apparatuses X to Z.

  However, the conventional remote monitoring service has the following problems.

  The conventional schedule of the regular connection 14 in FIG. 1 and the regular monitor 25 in FIG. 2 requires a customer or a service person to input the schedule on the customer apparatus side or the center side to set the regular connection 14. For this reason, the operation schedule of the customer device was changed from “Monday-Friday operation” to “365 days operation” or changed due to holidays that change every year such as New Year holidays and Bon holidays. If the service contract is changed from “24-hour monitoring” to “monitoring only at night”, the service person goes to the customer and changes the setting of the customer's device, or the customer contacts the center. You must request a change of settings. However, costs such as setting mistakes caused by serviceman operations and labor costs for the serviceman have increased, which has been a burden on customers.

  In practice, there is a time lag between the data processing device and the operation monitoring center, so that it is difficult to finely monitor the regular connection at the operation monitoring center. In particular, when multiple devices are managed at the operation monitoring center and there is a period in which the devices are suspended for a long period due to holidays such as New Year holidays, Bon holidays, Golden Week, etc., it is abnormal that there is no scheduled connection during the long suspension period In some cases, abnormalities could not be detected for a long time. For example, as shown in FIG. 3, when the next regular connection 2 after the last regular connection 1 before the suspension is scheduled after the start of the suspension, the operation monitoring center normalizes the regular connection 2 that is not connected from the apparatus. As a result, the determination of the abnormality of the terminal at the operation monitoring center is made based on the presence / absence of the next regular connection 3. Therefore, it is determined that the period from the regular connection 1 to the regular connection 3 is normal. In this case, there is a problem that if an abnormality of the device occurs after the regular connection 1 and before the start of the suspension, the abnormality cannot be detected for a considerable period of time.

  Therefore, it is easy to change the regular connection interval according to the operation status of each device, and a quick response is required.

  Accordingly, an object of the present invention is to provide an operation monitoring device and an operation monitoring system that individually monitor an abnormality of a device based on a periodic connection condition in which devices set in each device are periodically connected.

  In order to solve the above-described problems, the present invention provides an operation monitoring apparatus for monitoring the operation status of a plurality of apparatuses connected via a network, a periodic connection condition for the apparatus to periodically connect, and the apparatus. The periodic connection from each device is monitored based on the regular connection condition by referring to the device table for each device that records the time difference of the current time with the operation monitoring device, and the regular connection It is configured to include an abnormality detection means for detecting whether or not the apparatus has been received by determining whether or not the signal is received within the time difference range.

  In such an operation monitoring device, since the periodic connection conditions are recorded corresponding to each device, the devices are periodically monitored according to the regular connection conditions, and when there is no connection from the device, etc. Abnormalities can be detected.

  In addition, by configuring the periodic connection condition set in the apparatus to notify the monitoring apparatus via the network, it becomes possible to quickly cope with the need to change the regular connection condition.

  The regular connection condition has an operation schedule indicating an operation period of the apparatus and an abnormality detection period indicating a period in which periodic abnormality detection is required in the operation schedule.

  Further, the present invention provides a predetermined first regular connection condition preset for each device and a second regular connection condition indicating a condition for periodically connecting notified from each device via a network. And determining a third periodic connection condition for monitoring the operation status of the apparatus and recording it as a periodic connection condition in the apparatus table, and a third periodic connection determined by the determining means You may comprise so that it may have a decision condition report means which reports a condition to a corresponding apparatus.

  In such an operation monitoring device, it is possible to determine the third regular connection condition that the operation monitoring device makes appropriate based on the regular connection condition notified from the device.

  Therefore, since the appropriate third regular connection condition is determined for each device, it is possible to detect an abnormality individually for each device according to the appropriate third regular connection condition.

  In order to solve the above-described problem, the present invention provides an operation monitoring system in which an operation monitoring apparatus monitors the operation status of a plurality of monitored devices via a network. And a connection means for periodically connecting to the monitoring device by transmitting the current time of the monitored device according to a periodic connection condition indicating a condition for connecting to the monitoring device. Refers to the periodic connection condition by referring to the device table for each monitored device in which the periodic connection condition of the monitored device and the time difference between the monitored device and the operation monitoring device are recorded. Based on the above, the periodic connection from each device is monitored, and it is determined whether or not the periodic connection is received within the time difference range so as to have an abnormality detecting means for detecting an abnormality of the device. It can be formed.

  Such an operation monitoring system appropriately detects an abnormality of each monitored device in order to monitor the regular connection for each monitored device based on the time difference between the monitored devices and the monitoring device, for example. it can.

  The condition notifying means notifies the monitoring device of the periodic connection condition using e-mail or the like, for example.

  A program for causing a computer to execute the above means as a function, or a computer-readable storage medium storing the program may be used.

  According to the present invention, the monitoring device manages the periodic connection conditions of each device and monitors the status of each device only by setting the regular connection conditions for monitoring the devices installed on the customer side. be able to.

  In addition, the operation monitoring device is notified of a periodic connection condition for performing monitoring set by the monitored device, and the monitored device periodically connects to the operation monitoring device according to the periodic connection condition. The monitoring device can detect an abnormality of the monitored device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 4, the operation monitoring apparatus according to the embodiment of the present invention that is installed in the operation monitoring center and monitors the apparatus installed on the customer side is connected to the customer side apparatus periodically via the Internet. To detect the presence or absence of abnormality.

  An operation monitoring system that unilaterally notifies a device regular connection condition from a customer device and then detects an abnormality of the device according to the presence or absence of a regular connection based on the device regular connection condition of the customer device will be described.

  FIG. 5 is a diagram illustrating a first example of a functional configuration of the operation monitoring system.

  In the operation monitoring system illustrated in FIG. 5, the operation monitoring apparatus 100 includes a reception control unit 101, a regular connection reception unit 56, a regular connection condition reception unit 57, a device abnormality detection unit 58, and a device table 105. The device 110 that is a monitored device monitored by the operation monitoring device 100 includes a regular connection condition setting unit 111, a regular connection condition storage unit 112, a regular connection schedule unit 113, a transmission control unit 114, and a GUI 120 (Graphical User Interface).

  On the customer side, an administrator who manages the device 110 inputs a monitoring requirement 41 to be changed from a predetermined GUI 120 that sets a monitoring requirement for monitoring the device. The monitoring requirement 41 includes an operation schedule and an abnormality detection period. The abnormality detection period of the set monitoring requirement 41 is processed by the regular connection condition setting unit 111 and converted into a regular connection interval. The conversion rule is set in advance according to the reliability of the network between the apparatus and the operation monitoring apparatus 100, for example, at the time of setup when the apparatus is introduced. Or you may set the conversion rule which uses the input in GUI120 as a regular connection interval as it is. Therefore, the administrator can set the regular connection interval.

  When the monitoring requirement is set, the regular connection condition setting unit 111 of the apparatus 110 records the operation schedule and the converted regular connection interval in the regular connection condition storage unit 112 as the regular connection condition. Then, the regular connection condition setting unit 111 transmits the device regular connection condition 43 having the operation schedule and the regular connection interval from the transmission control unit 114 to the operation monitoring apparatus 100, and changes the regular connection condition to the regular connection scheduling unit 113. Notify and finish the process.

  The regular connection schedule unit 113 of the device 110 extracts the regular connection interval from the regular connection condition storage unit 112 when the device 110 is started up or for every change notification from the regular connection condition setting unit 111, and thereafter performs time monitoring. A regular connection 44 is made to the center at each regular connection interval.

  On the other hand, the operation monitoring apparatus 100 receives information from the apparatus 110 by the reception control unit 101. If the received information is the device regular connection condition 42, the reception control unit 101 passes the information to the regular connection condition reception unit 57. When the received information is the regular connection 44, the information is passed to the regular connection receiving unit 56.

  The regular connection condition reception unit 57 records the regular connection condition 43 in the regular connection condition of the device 110 in the device table 105 with the received information.

  The regular connection receiving unit 56 records that the regular connection 44 is present in the periodic storage reception information of the device 110 in the device table 105 in the received information.

  The apparatus abnormality detection unit 58 periodically detects the apparatus table 105 and detects an abnormality by determining an abnormality detection condition such that the periodic connection is not performed a plurality of times during the operation schedule.

  As described above, information regarding the periodic connection condition of the device 110 held by the operation monitoring device 100 by using e-mail such as the Internet for information indicating the regular connection condition changed by the device 110 on the customer side. Efficient remote monitoring service can be realized by rewriting the system.

  In addition, when operations such as normal power-off and power-on / reboot of the customer-side device 110 are performed during the regular connection interval, operation monitoring is performed from the device 110 at power-off, power-on, or restart. By making the regular connection 44 to the apparatus 100, the operation monitoring apparatus 100 can correctly monitor the apparatus 110.

  Next, a method will be described in which the operation monitoring device determines the final periodic connection condition based on the regular connection condition from the customer side device and notifies the customer side device.

  FIG. 6 is a diagram illustrating a second example of the functional configuration of the operation monitoring system.

  6, the operation monitoring apparatus 200 includes a reception control unit 101, a regular connection reception unit 56, a regular connection condition reception unit 57, a device abnormality detection unit 58, an operation monitoring adjustment unit 60, and monitoring level information 107. The device 210 that has the device table 108 and is a monitored device monitored by the operation monitoring device 100 includes a periodic connection condition setting unit 111, a periodic connection condition storage unit 112, a periodic connection scheduling unit 113, A transmission control unit 114, an operation monitoring information storage unit 115, an operation monitoring information reception unit 116, a reception unit 117, and a GUI 120 (Graphical User Interface) are included.

  In FIG. 6, the same parts as those in FIG.

  The device table 108 stores a monitoring level, regular connection conditions, past regular connection reception information, and operation monitoring information for each device.

  The monitoring level information 107 manages a maximum abnormality detection period and a minimum abnormality detection period, and an operation monitoring period as abnormality detection time information for each level. The maximum abnormality detection time is a guaranteed time width of the abnormality detection period in the operation monitoring service. For example, when the maximum abnormality detection period is 2 hours, there is a guarantee that the discovery of an abnormality will not be delayed for more than 2 hours. The minimum abnormality detection period depends on the serviceability of the operation monitoring service. For example, if the contract is subject to detection within 2 hours (maximum abnormality detection period is 2 hours), the device will move when a regular connection interval that can be detected within 1 hour is specified from the device side. Used as a reference for determining whether the monitoring center 200 accepts the designated regular connection interval.

  Similar to the first example of the operation monitoring system shown in FIG. 5, the monitoring requirement 44 including the operation schedule and the abnormality detection period is set in the customer-side device 210 using the GUI 120, and the abnormality detection period is regularly connected. The condition setting unit converts it into a regular connection interval, and the operation schedule and the converted regular connection interval are transmitted to the operation monitoring apparatus 200 as the apparatus regular connection condition 43 by the transmission control unit 114.

  In the second example shown in FIG. 6, the device 210 once completes the processing until receiving operation monitoring information from the operation monitoring device 200. At this time, the regular connection 55 due to the change is not yet made.

  In the operation monitoring device 200, when the reception control unit 101 receives the device regular connection condition 43 from the device 210, it passes it to the device regular connection condition reception unit 57.

  Upon receiving the device regular connection condition 43 from the reception control unit 101, the device regular connection condition receiving unit 57 stores the received device regular connection condition 43 in the device regular connection condition of the device table 108 corresponding to the device 210. Next, the device regular connection condition receiving unit 57 notifies the operation monitoring adjustment unit 60 that the device regular connection condition 43 has been received.

  The operation monitoring adjustment unit 60 acquires the monitoring level from the device table 108 corresponding to the device regular connection condition 43. The operation monitoring adjustment unit 60 refers to the monitoring level information 107 based on the acquired monitoring level, and acquires the maximum abnormality detection period, the minimum abnormality detection period, and the operation monitoring period. Based on the acquired maximum / minimum abnormality detection period, the upper and lower limits of the regular connection interval are calculated. Further, the operation monitoring adjustment unit 60 includes the operation schedule and the periodic connection interval of the device periodic connection conditions stored in the device table by the device periodic connection condition receiving unit 57, the acquired operation monitoring period, the maximum abnormality detection period, and the minimum From the abnormality detection period, an operation monitoring period and a regular connection interval used for actual operation monitoring are determined, set in the operation monitoring information of the device table 108, and the device 210 is notified of the operation monitoring information as a result.

  The transmission unit 109 receives the transmission request from the operation monitoring adjustment unit 60 and transmits the operation monitoring information 53 to the apparatus 210.

  When receiving the operation monitoring information 53 from the operation monitoring apparatus 200, the receiving unit 117 of the apparatus 210 notifies the operation monitoring information receiving unit 116 that the operation monitoring information 53 has been received.

  The operation monitoring information receiving unit 116 stores the operation monitoring information 53 in the operation monitoring information storage unit 115 and notifies the periodic connection scheduling unit 113 that the operation monitoring information has been updated.

  The regular connection scheduling unit 113 acquires the regular connection interval from the operation monitoring information storage unit 115 when the apparatus 210 is activated or when the operation monitoring information receiving unit 116 notifies the update of the operation monitoring information. Accordingly, the regular connection 55 is made to the operation monitoring apparatus 200.

  In the operation monitoring apparatus 200, when the reception control unit 101 receives the regular connection 55, the regular connection receiving unit 56 is notified of the regular connection 55.

  The regular connection receiving unit 56 stores the information received from the regular connection 55 in the secular device connection reception information of the device table 108 corresponding to the device 210.

  The abnormality detection unit 58 periodically searches the device table 108, and satisfies the abnormality detection condition such that the regular connection 55 does not come a predetermined number during the operation monitoring period based on the device regular connection condition and the regular connection reception information. Abnormality is detected by determining whether there is a device that is present.

  Next, details of the operation monitoring information update processing in the operation monitoring apparatus 200 for updating the regular connection 55 will be described with reference to FIGS. 6 and 7.

  FIG. 7 is a flowchart for explaining operation monitoring information update processing.

  As shown in FIG. 7, when the operation monitoring apparatus 200 receives from the apparatus 210 the apparatus regular connection condition 45 in which “365 days 24H” is specified as the operation schedule 1 and “1 hour” is specified as the periodic connection interval 1, the apparatus connection condition reception is performed. The unit 57 stores the device regular connection condition in the device table 108 corresponding to the device 210 (step S11).

  When the operation monitoring adjustment unit 60 receives the notification of the device periodic connection condition reception from the device periodic connection condition reception unit 57, the operation monitoring adjustment unit 60 acquires the monitoring level corresponding to the device 210 from the device table 108. The operation monitoring period 2 is acquired from the monitoring level information 107 corresponding to the acquired monitoring level. The operation schedule 1 specified from the apparatus 210 and the operation monitoring period 2 acquired are adjusted so that a narrow period is the operation monitoring period 3 for determining and notifying the apparatus 210. For example, if “365 days 19:00 to 08:00 (nighttime)” is set in the operation monitoring period 2, “365 days 19:00 to 08:00 (nighttime)” is determined as the operation monitoring period 3. The

  Further, the regular connection interval 3 is adjusted based on the regular connection interval 1 designated from the apparatus 210 and the acquired abnormality detection period 2 (step S12).

  The range of the regular connection interval that guarantees the detection time is determined from the abnormality detection period 2 indicated by the maximum and minimum abnormality detection periods. The abnormality detection period 2 indicated by the maximum and minimum abnormality detection periods is determined by the connection method between the apparatus 210 and the operation monitoring apparatus 200.

  Next, when the regular connection interval 1 of the device regular connection condition 45 set in the device table 108 is within the determination range, the regular connection interval 1 is set as the regular connection interval 3.

  On the other hand, when the regular connection interval 1 is outside the determination range, the value closest to the regular connection interval 1 of the device regular connection condition 45 within the range is set as the regular connection interval 3. For example, when the regular connection interval 1 is larger than the maximum detection period, the maximum detection period is determined as the regular connection interval 3. On the other hand, when the regular connection interval 1 is smaller than the minimum detection period, the minimum detection period is determined as the regular connection interval 3.

  In FIG. 7, when the abnormality detection period 2 is indicated by “2 hours” as the maximum abnormality detection period and “1 hour” as the minimum abnormality detection period, “1 hour” is set as the regular connection interval 3 as described above. .

  Therefore, the operation monitoring information in the device table 108 stores “365 days 19:00 to 08:00” as the operation monitoring period 3 and “1 hour” as the regular connection interval 3.

  Next, the operation monitoring adjustment unit 60 transmits the operation monitoring information of the device table 108 to the device 210 as the operation monitoring information 53 (step S13).

  6 and 7, the operation determined by adjusting the monitoring requirement 41 or 45 according to the monitoring level managed by the operation monitoring device 200 only by inputting the monitoring requirement 41 from the device 210 installed on the customer side. The monitoring condition can be notified to the apparatus 210 as well. Also, by this notification, it is possible to hold appropriate operation monitoring conditions in the operation monitoring apparatus 200 and the apparatus 210.

  Next, an abnormality detection determination process in consideration of a time difference of regular connection from an apparatus installed on the customer side in the operation monitoring apparatus will be described with reference to FIGS. This abnormality detection determination process can be applied to the first example of the functional configuration of the operation monitoring system shown in FIG. 5 or the second example of the functional configuration of the operation monitoring system shown in FIG.

  FIG. 8 is a diagram illustrating a third example of the functional configuration of the operation monitoring system.

  As shown in FIG. 8, in the operation monitoring system, the operation monitoring device 300 includes a reception control unit 101, a regular connection receiving unit 356, a regular connection condition receiving unit 57, a device abnormality detecting unit 358, an operation monitoring adjusting unit 60, A device 310 that has monitoring level information 107 and a device table 308 and is a monitored device monitored by the operation monitoring device 300 includes a periodic connection condition setting unit 111, a periodic connection condition storage unit 112, and a periodic connection. It has a schedule unit 313, a transmission control unit 114, an operation monitoring information storage unit 115, an operation monitoring information reception unit 116, a reception unit 117, and a GUI 120 (Graphical User Interface).

  In FIG. 8, the same parts as those of FIG.

  The operation monitoring information update process after the monitoring requirement 41 is input from the apparatus 310 installed on the customer side is performed in the same manner as the processes in FIGS.

  In the device 310, after receiving the operation monitoring information 53 notified from the operation monitoring device 300, the regular connection scheduling unit 313 sets the device time as information on the regular connection, and sends the regular connection 65 and the current device time to the transmission control unit 114. 66 are transmitted to the operation monitoring apparatus 300. The regular connection schedule unit 313 also has the function of the regular connection schedule unit 113 in the first example or the second example.

  When the periodic connection receiving unit 356 of the operation monitoring device 300 receives the notification of the periodic connection 65 having the device current time 66 received from the reception control unit 101, the periodic connection reception information of the device table 308 corresponding to the device 310 is configured. As the time difference information, the device current time 66 of the regular connection 65 and the current time of the center are stored.

  An abnormality detection time difference adjustment process for adjusting the time difference for abnormality detection is executed, and a time difference fluctuation correction value is determined (described later). The determined time difference fluctuation correction value is recorded as time difference fluctuation correction of the periodical connection reception information in the device table 308 corresponding to the device 310.

  The abnormality detection 358 periodically searches the device table 308 and determines whether an abnormality has occurred in each device based on the device-like connection condition and the periodic connection reception information. Details will be described later.

  Next, processing at the time of regular connection and abnormality detection time difference adjustment processing will be described with reference to FIGS. 9, 10 and 11. FIG.

  FIG. 9 is a flowchart for explaining processing at the time of regular connection and abnormality detection.

  As shown in FIG. 8, every time the regular connection 65 is received, the operation monitoring apparatus 300 executes the regular connection process shown in FIG.

  9A, when the regular connection receiving unit 356 of the operation monitoring apparatus 300 receives the regular connection 65 having the apparatus current time 66, the periodical connection receiving unit 356 acquires the apparatus current time 66 from the regular connection 65, and at the operation monitoring center. The time is acquired and recorded as time difference information of the periodic connection reception information in the device table 308 corresponding to the device 310 (step S31). Alternatively, the difference between the acquired device current time 66 and the operation monitoring center time (operation monitoring center time−device current time) may be recorded.

  For example, as shown in FIG. 10, the current time of the device at which the device 310 installed on the customer side transmits the periodic connection 65 is 8:00, and the operation monitoring device 300 of the operation monitoring center receives the periodic connection 65. If the current time of the center is 8: 4, the time difference indicated by the difference between the current time of the center and the current time of the device is 4 minutes.

  When the regular connection 65 is made by e-mail (e-mail) or the like, since it is transmitted via a plurality of intermediate servers (bucket relay format), the period for the regular connection on the apparatus side and the regular connection on the center side are made. The difference from the recognition time cannot be strict. In such a case, it is necessary to accumulate the time difference for several generations, calculate the time difference fluctuation, and correct the time.

  When it is necessary to correct the fluctuation of the time difference, the abnormality detection time difference adjustment process P300 is executed following step S31.

  In the abnormality detection time difference adjustment process P300, every time the regular connection 65 is received from the device 310, the time difference is accumulated and accumulated in minutes. The average of the time differences for a predetermined number of times is calculated.

  For example, as shown in FIG. 11, when the predetermined number of times is 10, the time difference fluctuation correction is an average value of 5.6 minutes obtained by dividing the sum of the time differences for 10 times by 10. The calculated time difference fluctuation correction is recorded in the time difference fluctuation correction of the periodical connection reception information in the device table 308. The abnormality detection time difference adjustment process P300 ends.

  The time difference fluctuation correction set in the abnormality detection time difference adjustment process P300 is referred to during the abnormality detection process.

  By the abnormality detection time difference adjustment process P300, it is possible to detect an abnormality in consideration of the transmission state of the intermediate server.

  Next, the abnormality detection process will be described.

  The apparatus abnormality detection unit 358 in FIG. 8 periodically performs the detection process shown in FIG.

  In FIG. 9B, the device abnormality detection unit 358 extracts the regular connection reception information and the operation monitoring information for each device from the device table 308 (step S35).

  At the start of the operation monitoring schedule of the operation monitoring information, it is determined based on the time difference information of the periodical connection reception information whether the delay of the periodical connection is within the time difference range (step S36). If the delay of the regular connection is within the time difference range, the process proceeds to step S37 to perform the next check. When the delay of the regular connection is not within the time difference range, the abnormal time process P400 is executed.

  For example, as shown in FIG. 9, at the start of the operation monitoring schedule of the operation monitoring information, that is, at 19:00, when the delay of the regular connection is within the time difference range based on the time difference information of the regular connection reception information, no abnormality is detected.

  At the end of the operation monitoring schedule of the operation monitoring information, based on the time difference information of the periodic connection reception information, it is determined whether or not the regular connection earlier than planned is within the time difference range (step S37). If the scheduled connection earlier than planned is within the time difference range, the process proceeds to step S38 to perform the next check. When the regular connection earlier than the schedule is not within the time difference range, the abnormal time process P400 is executed.

  For example, at the end of the operation monitoring schedule, that is, at 8 o'clock, the fact that the regular connection was quickly completed within the time difference range is not detected as an abnormality.

  The scheduled connection time is obtained from the operation monitoring schedule of the operation monitoring information and the regular connection interval, and it is determined whether the regular connection is within the time difference from the scheduled regular connection time (step S38). If it is within the time difference from the scheduled connection time, the process proceeds to step S39. If it is not within the time difference from the scheduled connection time, the abnormal time process P400 is executed.

  For example, in the operation monitoring schedule of the operation monitoring information shown in FIG. 9, there was a regular connection within the time difference from the scheduled connection scheduled times at 19:00, 20:00, 21:00, ..., 7 and 8 o'clock. If it is, do not detect the abnormality.

The time difference range is, for example, “+4 minutes” when the time difference information of the periodic connection reception information is set, and “+5.6 minutes” when the time difference fluctuation correction of the periodic connection reception information is set. Alternatively, it may be set to “+11.2 minutes” which is twice as much as the network state.

  The process returns to step S35 to check the next device table.

  When all the device tables are searched, the abnormality detection process is terminated.

  As described above, when the time between the device 310 installed on the customer side and the mobile monitoring center is different, the operation monitoring device 300 can automatically correct the time difference and realize appropriate operation monitoring. In addition, when a delay occurs due to the connection form such as e-mail between the device 310 and the operation monitoring center, the operation monitoring device 300 can dynamically correct the delay, so that appropriate operation monitoring can be performed. Become.

  Next, another method for notifying the apparatus regular connection condition from the apparatus installed on the customer side to the operation monitoring apparatus will be described.

  FIG. 12 is a diagram illustrating a fourth example of the functional configuration of the operation monitoring system.

  12, in the operation monitoring system, the operation monitoring device 400 includes a reception control unit 101, a regular connection receiving unit 456, a regular connection condition receiving unit 57, a device abnormality detecting unit 58, an operation monitoring adjusting unit 60, A device 410 that has monitoring level information 107 and a device table 108 and is monitored by the operation monitoring device 400 includes a periodic connection condition setting unit 411, a periodic connection condition storage unit 112, and a periodic connection. It has a schedule unit 413, a transmission control unit 114, an operation monitoring information storage unit 115, an operation monitoring information receiving unit 116, a receiving unit 117, and a GUI 120 (Graphical User Interface).

  In FIG. 12, the same parts as those in FIG.

  When the customer inputs and sets the monitoring requirement 41 from the GUI 120, the periodic connection condition setting unit 411 of the apparatus 410 installed on the customer side differs from the processing in the operation monitoring system shown in FIGS.
