Description

  The present invention relates to a monitoring network system and a data backup method for monitoring a system composed of a large number of devices.

  In a supervisory control system and an information processing system, a redundant configuration is taken in preparation for a failure of an apparatus or a system. In this case, it is necessary to perform data copy at high speed between the memory systems between the active system and the standby system or between the active system and the standby system. In such a case, when data for backup is transferred via a data line or a network, data copying is often performed between both memory devices using a cache memory (for example, Patent Document 1).

  However, an infrastructure monitoring system in which many devices such as a communication network are installed in a wide area is prepared for the failure of the monitoring function itself, and the system configuration of the monitoring function is doubled between the active system and the standby system. In many cases, the monitoring apparatus (host) configured in a separate configuration is further configured with a monitoring facility having a redundant configuration of an active system and a standby system. In this case, the active system device performs data storage processing on the shared memory device with the standby system, and also transfers data to the shared memory device similarly provided in the standby system via the network. Data backup processing is required.

  Since the monitoring data of the monitored device that is monitored regularly is also received via the network, the data backup processing of the monitoring device in operation of the active system and the processing with the network become enormous, The resources of the monitoring device are approaching the limit and the monitoring processing capacity is reduced.

FIG. 2 is a functional block diagram for explaining the operation and function of a monitoring control system in which a conventional redundant apparatus configuration is further doubled.
In FIG. 2, the monitoring control system for monitoring the monitored devices 9 (# 1 to #n) via the monitoring control network 400 is installed in the monitoring system 100, the monitoring system 200, and the monitoring center C of the active system and the standby system. The monitor console 300 is provided.

  The active monitoring facility 100 and the standby monitoring facility 200 basically have the same configuration and function. The active monitoring facility 100 includes an active monitoring host 110A, a standby monitoring host 110B, and a shared memory 120 connected to both hosts via a memory bus or the like. The configuration is the same. As a general rule, the role assignment of the active and standby systems, as well as the active and standby monitoring hosts, is set in advance when the system is started, and each component performs operation processing according to the settings.

  The active monitoring host 110A further includes an NWIF (network interface) unit 111, a backup control unit 112, a data collection processing unit 113, and a console management unit 114, each of which is connected via an internal bus or the like. The internal configuration of the monitoring host 110B is the same. In addition, the monitoring hosts for the operation system and the standby system of the standby monitoring facility 200 have the same internal configuration. In FIG. 2, the configuration common to both the monitoring facilities 100 and 200 is represented by the monitoring host 110 </ b> A unless necessary so as to avoid the complexity of the drawing, and illustration of the others is omitted.

  The data collection processing unit 113 of the active monitoring host 110A, for example, periodically sends polling data and commands to the monitored devices 9 (# 1 to #n) via the NWIF unit 111 and the monitoring control network 400. The data collected by transmitting and receiving data is written to and stored in the shared memory 120.

  In addition, the data collection processing unit 113 includes data collected from each monitored device 9 and data collected by the internal test means (not shown) of the monitoring host 110A itself that deviates from a predetermined reference value. In this case, the alarm is output to the monitor console 3 via the backup control unit 112 and the monitoring control network 400 via the internal bus.

  The console management unit 114 of the active monitoring host 110A reads required data from the shared memory 120 in accordance with a command from the monitor console 300, and monitors the data via the NWIF unit 111 and the monitoring control network 400 in a predetermined data format. Send to console 300. Further, when a command for switching between the active system and the standby system, or the active system and the standby system in those systems is received from the monitor console 300, the backup control unit 112 is further notified of the command. The backup control unit 112 performs control related to required redundant configuration switching in accordance with the received command.

  The backup control unit 112 of the active monitoring host 110A is a CPU that manages and controls processing operations of the entire monitoring host 110A. Normally, in preparation for system switching, data processing performed by the active monitoring host 110A and control of the shared memory 120 are performed in a predetermined procedure. If the system switching command from the monitor console 300 or the alarm received from the data collection processing unit 113 corresponds to a case where automatic switching of a predetermined system is performed, an internal bus, an internal LAN, or the like Thus, redundancy processing and switching processing are performed with the backup control unit 112 of the standby monitoring host 110B.

  Furthermore, the backup control unit 112 of the active monitoring host 110A for the active system reads out the data in the shared memory 120 and prepares for switching between the active system and the standby system via the NWIF unit 11 and the monitoring control network 400. Data is transmitted to the monitoring host 210 </ b> A that is the operational system of the standby monitoring facility 200. This data transmission is performed according to a predetermined processing procedure with the backup control unit 112 of the standby monitoring host 210A.

  In the monitoring host 210A, the backup control unit 112 writes and stores the data received via the monitoring control network 400 and its own monitoring control network 400 in the shared memory 120 of the monitoring host 210A, and prepares for switching between the active and standby systems.

As described above, in the conventional monitoring system in which the redundant configuration is further duplicated, the burden on the backup processing unit 112 of the active monitoring host 110A is very large. For example, a plurality of monitored devices 9 When an abnormality occurs, there is a problem that the data processing is congested and the system capacity is rapidly reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a functional block diagram for explaining the operation of the monitoring network system according to the embodiment of the present invention.
In FIG. 1, a monitoring control system for monitoring monitored devices 9 (# 1 to #n) via a monitoring control network NW includes an active system (system), a standby system (system) monitoring equipment 1, and a monitoring equipment 2. The monitor console 3 installed in the monitoring center C is provided.

  The supervisory control network NW is an IP network, and is, for example, a wide-area Internet network, a dedicated LAN, a WAN, or the like. The monitor console 3 and the monitored device 9 transmit / receive monitor data of each monitored device 9 and display information indicating the operation state to / from the monitoring facility 1 via the monitoring control network NW. Monitor data necessary for backup, control information, and the like are also transmitted between the active and standby monitoring facilities via the monitoring control network NW.

  The active monitoring facility 1 connects the active monitoring host 1A, the standby monitoring host 1B, the shared memory 1M connected to both hosts via a memory bus or the like, and both monitoring hosts 1A, 1B. And an internal LAN 14. Similarly, the configuration of the standby monitoring facility 2 includes the active monitoring host 2A, the standby monitoring host 2B, and the shared memory 2M connected to both hosts via a memory bus or the like. And an internal LAN 14 for connecting the two monitoring hosts 2A and 2B.

  The monitoring host here is a monitoring device that collects and manages monitor data, which is also called a monitoring server, and is hereinafter referred to as a monitoring host.

  The active monitoring facility 1 and the standby monitoring facility 2 basically have the same configuration and function. Then, initialization of allocation of the active system, the standby system, the active system, and the standby system is performed in advance, and the same data is written and stored in both shared memories 1M and 2M.

  Each of the monitoring hosts 1A, 1B, 2A, and 2B includes a console management unit 10, a data collection unit 11, a management control unit 12, and an NWIF (network interface) unit 13. Console management is performed in each monitoring host. The units 10 to NWIF 13 are interconnected by an internal bus or the like.

  The NWIF unit 13 is a communication interface between the monitoring control network NW and the internal LAN 14. For example, the NWIF unit 13 executes a TCP / IP procedure, and whether the active monitoring host 1 A communicates with the monitored terminal 9 and the monitor console 3. Alternatively, IP packet transmission processing is performed between the standby monitoring host 1B and the standby monitoring facility 2.

  The internal buses of the monitoring hosts 1A and 1B are further connected directly to the memory bus with the shared memory 1M, and the internal buses of the monitoring hosts 2A and 2B are further connected to the memory bus with the shared memory 2M directly or by bus interface means (not shown). Each monitoring host can access the respective shared memory.

  In FIG. 1, the configuration common to both the monitoring facilities 1 and 2 is shown as a representative of the monitoring host 1 </ b> A unless necessary so as to avoid the complexity of the drawing, and the other components are not shown.

  For each function that operates in the active / standby system, each function should be started and stopped by a redundant function that performs operation / standby control during device startup and system switching, and should operate in the active / standby system and operating system operation. Decide the function.

  Between the active system and the standby system, the operation program is registered in advance in both shared memories or in each management control unit 12 as described above. In accordance with information related to the system status (system switching, system down, system activation) received from the self-diagnosis means of each system (not shown), the management control units 12 mutually monitor and control the new operation / standby system information, and Notifications are made via the internal LAN 14, and the operation of the own monitoring device is controlled with reference to the operation / standby system information about the own system and the partner system.

  The management control unit 12 of the active monitoring host 1A of the active monitoring facility 1 has a monitoring function and an inter-system differential transfer function (hereinafter referred to as difference) performed between the active system and the standby system in the active system, by default. A program that executes processing) is resident. The management control unit 12 of the standby monitoring host 1B is resident with a program for executing an intersystem backup function (hereinafter referred to as intersystem processing) between the active system and the standby system.

  The data collection processing unit 11 of the active monitoring host 1A is managed by a monitoring function execution program executed by the management control unit 12. For example, the NWIF unit 13 and the monitoring control network NW regularly send polling data and commands. The data is collected by transmitting and receiving to / from the monitored devices 9 (# 1 to #n) via the.

  Further, the data collection processing unit 11 includes data collected from each monitored device 9 and data collected by the self-diagnosis means (not shown) of the monitoring host 1A itself that deviates from a predetermined reference value. In this case, an alarm is output to the monitor console 3 via the internal control bus 12 and the monitoring control network NW via the internal bus.

  The console management unit 10 of the active monitoring host 1A reads out the required data from the shared memory 1M according to the command from the monitor console 3, converts it to a predetermined data format, and monitors it via the NWIF unit 13 and the monitoring control network NW. Send to console 3. Further, when the switch command between the active system and the standby system, or the active system and the standby system in those systems is received from the monitor console 3, the command is further notified to the management control unit 12. The management control unit 12 performs control related to required redundant configuration switching in accordance with the received switching command.

  The management control unit 12 of the active monitoring host 1A that manages and controls the overall processing operation of the monitoring host 1A normally performs data processing performed by the active monitoring host 1A in a predetermined procedure in preparation for system switching. The shared memory 1M is controlled.

  That is, for example, the management control unit 12 further writes and stores data collected by polling or survival confirmation by the data collection management unit 17 in the shared memory 1M, and also updates data to the standby monitoring host 1B. Controls differential processing for transmission. That is, each data on the shared memory 1M is provided with a write pointer (not shown) indicating a write history and updated at the time of writing.

  The data collection processing unit 17 performs a differential process for writing data to the shared memory 1M when there is a difference from the previous monitor data after polling or survival confirmation.

  The process of transferring the updated data from the active system to the standby system for backup is executed by the monitoring host 1B which is the standby system. In the differential processing executed by the management control unit 12 of the monitoring host 1A, each data transferred to the monitoring host 1A of the standby monitoring host 1B via the NWIF unit 13 and the internal LAN 14 is transferred between systems indicating a transfer history. A transfer pointer (not shown) that is sometimes updated is provided to compare the transfer pointer with the write pointer.

  Data transfer is performed cyclically for each piece of data, but if there is a change in the operation of the monitored device before the new transfer, the monitor data pointer is “5”, for example. The transfer pointer has a different value such as “3”. Then, both pointers coincide with each other as shown in “5” and transferred to the latest write data to the inter-system backup function (inter-system processing) executed by the management control unit 12 of the standby monitoring host 1B of the active system. The transfer is repeated until it is determined that the

  On the other hand, if the pointers match when they are compared, data transfer is not performed, so the load on the management control unit 12, NW interface, internal LAN 14 and the like is reduced by this difference processing.

  In addition, this data transfer may originally be performed via the memory bus MB, but here the priority is lower than the monitoring data collection, and the data is transferred by the processing of the NWIF unit 13 via the internal LAN 14. The burden on the control unit 12 is further reduced.

  Subsequently, in the inter-system processing executed by the management control unit 12 of the standby monitoring host 1B of the active monitoring facility 1, the data transferred between the systems to the standby system is transmitted via the NWIF unit 13 and the monitoring control network NW. Then, it is transferred to the inter-system backup function (inter-system processing) executed by the management control unit 12 of the standby monitoring host 2B of the standby monitoring facility 2.

  The transferred data is further transferred to differential processing executed by the management control unit 12 of the active monitoring host 2A of the standby monitoring facility 2 by inter-system processing executed by the management control unit 12 of the monitoring host 2B. This data transfer is performed via the internal LAN 14 of the standby monitoring facility 2 as in the active system. Then, it is determined that the difference processing is written and stored with the data pointer written to the shared memory 2M matching the value of the transfer pointer corresponding to the case where it is performed in the active system. It is written and stored until it is done.

  As described above, in the monitoring network system according to the embodiment of the present invention, a total of four management control units 12 included in the active and standby monitoring facilities share functions (loads), respectively, and perform data transfer processing. A process executed by the management control unit of the monitoring facility serving as the active operation system by performing a backup in which the contents of the spare shared memories are the same and transferring the data using each internal LAN 14 There is enough capacity to prevent congestion that would hinder the update of collected data.

  In addition, the four management control units 12 determine which programs are to be activated by initial settings, but each stores and saves differential processing and intersystem processing programs. Even if one of them breaks down, the management control unit of the monitoring host that becomes the operating system of the monitoring facility can transfer the data to the standby system by starting the inter-system processing program.

  The present invention is not limited to the above-described configuration, and a mode in which the above-described configurations are combined without departing from the gist of the present invention can also be applied. For example, the monitor console 3 may be further connected to the console management units 10 of the monitoring facilities 1 and 2. Further, the number of NWIF units 13 is not limited to one, and a plurality of monitoring control networks NW and internal LANs 14 may communicate with each other by a procedure other than the TCP / IP procedure.
