BACKGROUND OF THE INVENTION
The present invention relates to a manager-agent monitoring control system in which an agent device to be monitored and a manager device that monitors and controls the same are connected via a network, and more particularly, a notification stored as history information during recognition of the device configuration of the agent device. relates the agent monitoring and control system status-matching method and program - status-matching processing manager performs on the basis of the information - the agent monitoring and control system, the agent device and manager.
[0002]
[Prior art]
In a manager-agent monitoring control system in which an agent device to be monitored and a manager device that performs monitoring control are connected via a network, state matching between the manager device and the agent device is essential. That is, when communication is newly established from a state where communication between the manager device and the agent device has been interrupted for a certain period, for example, hardware (hereinafter referred to as H / W) resources implemented by the agent device are: There may be a difference between before the period when communication was interrupted and when communication was newly established. In such a case, the manager device reads out information related to the H / W configuration as information necessary for monitoring control of the agent device, and performs state matching. The manager-agent monitoring control system operates by completing the state matching between the two at the time of establishing such communication.
[0003]
Here, a simple flow of the state matching operation will be described.
When the communication state with the manager device is established, the manager device requests the agent device for information regarding the current state of the agent device and the H / W implemented in the agent device (hereinafter referred to as a call request). . For example, H / W configuration information, H / W alarm information, H / W status information, and the like of the agent device are required. Here, the H / W configuration information includes, for example, information that defines the slot configuration of the computer device constituting the agent device and the type of H / W registered for each slot. The H / W alarm information includes, for example, failure information that has occurred in the agent device, information that indicates the occurrence / recovery of the failure occurrence, and the time of occurrence / recovery thereof. Further, the H / W status information includes the operating status of the computer device and system constituting the agent device, the type of communication line handled by the computer device, the transmission speed of the communication line, and the usage rate of the line.
[0004]
The agent device responds with information corresponding to the call request from the manager device as described above. As a result, the manager device recognizes the state of the agent device to be monitored and controlled, performs internal settings according to this, and completes state matching.
[0005]
On the other hand, if a failure or state change occurs in the agent device before the state matching by the manager device is completed, the agent device autonomously relates to the state change and the like asynchronously with the response to the call request from the manager device. Information is notified to the manager device. The notification information includes, for example, information indicating a failure type that identifies a failure that has occurred in the hardware installed in the agent device, the occurrence / recovery of the failure, and its time. In addition, information indicating a change in the operating state of H / W may be considered.
[0006]
The manager device sequentially receives response information to the call request from the agent device and notification information that is transmitted asynchronously with the failure or state change of the agent device. Accordingly, the manager device recognizes the H / W configuration of the agent device based on the response information, and performs the state matching process by reflecting the content of the notification information on this.
[0007]
FIG. 5 is a diagram showing an overview of state matching by a conventional manager-agent monitoring control system. In this figure, an example is a monitoring control system in which the manager device does not hold the MIB (Management Information Base) and does not recognize the H / W configuration information implemented by the agent device. In such a system, before the manager device generates the H / W configuration information of the agent device based on the response information to the call request, the manager device reflects the notification information regarding the H / W configuration even if it is received. I can't.
[0008]
In this case, the manager device sequentially stores such notification information and proceeds with recognition processing of the H / W configuration of the agent device based on response information to the call request. Specifically, the manager device generates device configuration information for specifying the H / W configuration of the agent device based on the response information. When the device configuration information of the agent device is generated, the manager device reads the notification information from the agent device and performs a state matching process that reflects them.
[0009]
In the operation as described above, notification information may be frequently generated from the agent device before recognizing the H / W configuration of the agent device. In this case, when the notification information storage memory overflows, the manager device discards the received notification information and proceeds with the recognition processing of the agent device H / W configuration.
[0010]
[Problems to be solved by the invention]
Since the conventional manager-agent monitoring and control system is configured as described above, a complicated state matching process may be required at the time of starting the system, and until the manager device can monitor and control the agent device. There was a problem that the start-up time was delayed.
[0011]
The above problem will be specifically described.
As described above, the response information to the call request may be overtaken by the state change notification information having the same attribute. At this time, the manager device stores the notification information until the H / W configuration is recognized. Then, after recognizing the H / W configuration, it identifies which agent device the read notification information relates to, and which H / W corresponds to, and in which time series the notification information corresponds. The state matching process is performed by specifying whether it belongs. Such a complicated state matching process is performed for all notification information stored in the internal memory. As a result, the startup time of the manager-agent monitoring control system may be delayed.
[0012]
Further, when the notification information is frequently generated from the agent device and the memory overflows, the manager device may discard the received notification information. In this case, from the viewpoint of the agent device, wasteful information to be discarded is sent to the network, which places a load on the network. On the other hand, when considering from the manager device side, the state matching process cannot be performed on the discarded notification information. Therefore, there is a possibility that a contradiction occurs in the time series of information required for state matching.
[0013]
The present invention has been made to solve the above-described problems. When a communication connection is established, the agent device stops sending notification information to the manager device and stores the notification information as history information. When the device configuration of the agent device is recognized, the state matching processing with the agent device is performed based on the history information stored so far, thereby reducing the processing load on the manager device and the complexity of the processing at the time of state matching. manager - it is possible to shorten the rise time of the agent monitoring and control system, the manager can suppress the transmission of unnecessary information to the network to reduce network load - agent monitoring, the agent device and Manager - Agent monitoring control system status matching method An object of the present invention to provide a program to beauty.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below.
Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of a manager-agent monitoring and control system according to Embodiment 1 of the present invention. FIG. b) shows a system in which one manager device monitors and controls a plurality of agent devices, and (c) shows one agent device monitors and controls a plurality of agent devices, and one agent device monitors by a plurality of manager devices. Indicates the system to be controlled. In the figure, reference numerals 1, 11-1 N are manager devices that monitor and control the agent devices 2, 21-2 N, and are realized by a computer device that executes a program for performing a state matching operation described later. Reference numerals 2, 21 to 2N are agent devices to be monitored, which have means for communicating with the manager devices 1 and 11 to 1N, and are realized by a computer device that executes a program for performing a state matching operation described later. The arrows in the figure are bidirectional communication lines that mediate information transmission between the manager devices 1, 11 to 1N and the agent devices 2, 21 to 2N.
[ 0019 ]
FIG. 2 is a diagram showing a specific example of the manager-agent monitoring control system in FIG. 1, in which (a) shows the configuration of the agent devices 2 and 21N , and (b) shows the slot configuration of the agent device. The display screen of the manager device is shown. In the figure, the part describing DS3, OC3, OC12 and APON indicating the thickness of the communication line connected to the network and the network type indicates a communication board (communication H / W) using these communication lines. . Further, in the system shown in the figure, an example is shown in which TMN (Telecommunications Management Network) which is an interface specification for uniformly managing agent devices of different vendors connected on the Ethernet (R) network is used. Therefore, the agent devices 2 and 21 to 2N have an interface function that uses TMN. In addition, the same code | symbol is attached | subjected to the same component as FIG. 1, and the overlapping description is abbreviate | omitted.
[ 0020 ]
Next, the operation will be described.
FIG. 3 is a diagram showing a state matching operation by the manager-agent monitoring control system according to the first embodiment. The system configuration in FIG. 1C will be described as an example.
First, for example, the manager device 11 requests communication establishment with the agent device 2m (1 ≦ m ≦ N). In response to this, the agent device 2m sends back a communication establishment completion response to the manager device 11, and at the same time, suppresses transmission of notification information that reports a failure or state change that occurs in itself. More specifically, the manager device 11 is specified by the communication establishment request received from the manager device 11 by the agent device 2m. Thereby, the agent device 2m determines that the initial state matching with the manager device 11 is not completed, and suppresses the transmission of the notification information to the manager device 11 simultaneously with the reply of the communication establishment completion response. The said operation | movement is made | formed by the notification suppression means embodied by the program which has a function which suppresses transmission of notification information.
[ 0021 ]
At this time, as shown in FIG. 3, the agent device 2m does not suppress the transmission of the notification information to the manager device 1n (1 <n ≦ N) that is already in the communication established state and the initial state matching is completed.
[ 0022 ]
Further, the manager devices 11 to 1N do not have a function of holding H / W configuration information of the agent devices 21 to 2N. For this reason, the manager device 11 does not recognize the H / W configuration information of the agent device 2m. In the example of FIG. 2, the manager device 11 does not recognize the H / W configuration shown in FIG. 2A, and displays the slot configuration screen of the agent device 2m as shown in FIG. It is not possible.
[ 0023 ]
Subsequently, the manager device 11 requests the agent device 2m to read the latest history serial number n. Further, upon receiving the request, the agent device 2m responds to the manager device 11 with the latest history serial number n. Here, the history serial number is information (such as a serial number assigned according to the time of occurrence) for identifying an event (failure or state change) that has occurred in the agent device 2m. That is, the manager device 11 requests / acquires only the latest history serial number for identifying the agent device 2m, not the latest notification information content. In the agent device 2m, notification information is held in association with the history serial number. In this way, a so-called history of the notification information identified by the history serial number in the agent device 2m is taken. The operation is performed by a notification history storage unit embodied in a memory and a program having a function of recording the notification information in association with the history serial number.
[ 0024 ]
When the manager device 11 acquires / holds the latest history serial number, the manager device 11 obtains information (H / W configuration information, etc.) necessary for state matching from the agent device 2m during the period surrounded by the broken line with the symbol A in FIG. Device configuration information related to the read agent device 2m is generated. The operation is performed by a device configuration recognition unit embodied by a program having a function of receiving the H / W configuration information and recognizing the device configuration of the agent device 2m. At this time, the agent device 2m keeps collecting the history of the notification information related to the generated event in association with the history serial number regardless of the presence or absence of the notification suppression state for the manager device 11.
[ 0025 ]
In the example of FIG. 2, the manager device 11 recognizes the slot configuration of the agent device 2m as shown in FIG. 2B as the device configuration information related to the agent device 2m. Specifically, it can be seen that H / Ws for controlling communication such as OC3, OC12, DS3, etc. are mounted in the slots indicated by diagonal lines in FIG. However, since the state matching is not completed in this state, the operation state of each H / W is not recognized.
[ 0026 ]
When the recognition of the H / W configuration of the agent device 2m is completed in the period A described above, the manager device 11 records history information (notification information) corresponding to the history sequence numbers (n + 1) to N after the latest history sequence number n described above. To the agent device 2m. This operation is performed by history information acquisition means embodied by a program having a function of requesting and acquiring history information.
[ 0027 ]
As a result, the agent device 2m transmits all history information corresponding to the history sequence numbers after the latest history sequence number described above to the manager device 11 (see the period indicated by the symbol B in FIG. 3). Thereafter, the agent device 2m cancels the notification suppression to the manager device 11.
[ 0028 ]
The manager device 11 performs state matching based on the received history information. At this time, the notification received during the state matching based on the history information is queued in the manager device 11 and the state matching is performed in chronological order. The operation is performed by a state matching unit embodied by a program having a function of performing state matching based on history information.
[ 0029 ]
Referring to the example of FIG. 2, when the manager device 11 completes the state matching with the agent device 2m, the manager device 11 displays the status display of the H / W mounted in the slot of the agent device 2m as shown in FIG. A GUI for performing the control is provided. Specifically, on the display screen shown in FIG. 2 (b), the slot in which the faulty H / W is mounted is displayed differently from other normal H / W slots (for example, normal It is conceivable to apply a green color, and a red color is applied to the troubled one).
[ 0030 ]
Next, the case where the agent apparatus requests the manager apparatus to establish communication will be described.
FIG. 4 is a diagram showing another example of the state matching operation by the manager-agent monitoring control system according to the first embodiment. The system configuration in FIG. 1C will be described as an example.
First, the agent device 2m requests communication establishment with the manager device 11. In response to this, the manager device 11 returns a communication establishment completion response to the agent device 2m. Upon receiving this communication establishment response, the agent device 2m suppresses transmission of notification information to the manager device 11. Since the subsequent processing is the same as that described above, a duplicate description is omitted.
[ 0031 ]
As described above, according to the first embodiment, when the communication connection is established between the manager device 11 and the agent device 2m, the agent device 2m transmits the notification information that tells the manager device 11 the event that has occurred to itself. When the manager device 11 acquires information for specifying the device configuration from the agent device 2m and recognizes the H / W configuration, the device device recognizes the device configuration from the agent device 2m. Since the history information stored therein is sequentially acquired and the state matching process is performed by reflecting the history information in each apparatus configuration, the system startup time can be shortened. In particular, this is effective for shortening the start-up time in a system in which notification information regarding state changes from the agent device 2m is frequently generated. In addition, since transmission of notification information is suppressed, it is possible to suppress the generation of unnecessary information and reduce the network load.
[ 0032 ]
In the first embodiment, the system configuration shown in FIG. 1C has been described. Needless to say, the system configuration shown in FIGS. 1A and 1B can also be applied.
[0033]
【The invention's effect】
As described above, according to the present invention, notification information that conveys an event that has occurred to the manager device is transmitted to the manager device that monitors and controls via the network , and the requesting manager device is identified by receiving a communication establishment request from the manager device. When the communication connection is established between the identified manager device and the agent device, the agent device stops sending notification information that tells the identified manager device an event that has occurred to itself, and the notification information is recorded as history information. When the manager device acquires information identifying the device configuration from the agent device and recognizes the device configuration, the agent device sequentially acquires the history information stored during the device configuration recognition from the agent device. It cancels the stop of the sending of the notification information, history on each device configuration of the agent device Since reflects the distribution performs state matching processing, there is an effect that it is possible to shorten the startup time of the system. In particular, this is effective for shortening the start-up time in a system in which notification information regarding state changes from the agent device occurs frequently. In addition, since transmission of the notification information is suppressed, it is possible to reduce the network load by suppressing the generation of unnecessary information.
