Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field 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 for monitoring and controlling the same are connected via a network, and more particularly, while recognizing the device configuration of the agent device. The present invention relates to a manager-agent monitoring control system, a manager device, an agent device, and a manager-agent monitoring control system state matching method and program for performing a state matching process based on notification information stored as history information.

[0002]

2. Description of the Related Art In a manager-agent supervisory control system in which an agent device to be monitored and a manager device for monitoring and controlling the same 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 in which 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 mounted on the agent device are There may be a difference between before the period when communication was interrupted and when new communication is established. In such a case, the manager device reads the information related to the H / W configuration as the information required for the supervisory control of the agent device and performs the state matching. The manager-agent monitoring and control system operates by completing the state matching between the two when establishing communication.

Here, a simple flow of the state matching operation will be described. When communication status is established with the manager device,
The manager device requests the agent device for information about the current state of the agent device and H / W installed therein (hereinafter, referred to as a call request).
For example, H / W configuration information of the agent device, H / W alarm information, H / W status information, and the like are required. here,
The H / W configuration information includes, for example, the slot configuration of the computer device that constitutes the agent device and information that defines the type of H / W registered for each slot. Further, 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 the occurrence / recovery. Furthermore, H /
The W status information includes the operating status of the computer device or system that constitutes the agent device, the type of communication line handled by the agent device, the transmission speed of the communication line, the line usage rate, and the like.

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 the internal setting according to the state, and completes the state matching.

On the other hand, if a failure or a state change occurs inside the agent device before the state matching by the manager device is completed, the agent device autonomously and asynchronously responds to the response to the call request from the manager device. The manager device is notified of information regarding changes and the like.
The notification information includes, for example, a failure type that specifies a failure that has occurred in the H / W installed in the agent device, information that indicates the occurrence / recovery of the failure, and the time of the failure. Also,
Information indicating changes in the operating state of the H / W is also conceivable.

The manager device sequentially receives the response information to the call request from the agent device and the notification information that is transmitted asynchronously with this and notifies the failure or state change of the agent device. As a result, the manager device makes the H of the agent device based on the response information.
The / W configuration is recognized, and the contents of the notification information are reflected in this to perform the state matching process.

FIG. 5 is a diagram showing an outline of state matching by a conventional manager-agent monitoring control system.
In this figure, the manager device is a MIB (Manager).
The monitoring control system does not hold the ent Information Base) and does not recognize the configuration information of the H / W installed by the agent device. In such a system, the manager device makes the H / H of the agent device based on the response information to the call request.
Even if the notification information regarding the H / W configuration is received before the W configuration information is generated, it cannot be reflected.

In this case, the manager device sequentially stores such notification information and advances the recognition processing of the H / W configuration of the agent device based on the response information to the call request. Specifically, the manager device generates device configuration information that specifies 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 the state matching process in which the notification information is reflected.

Further, in the above-mentioned operation, notification information may be frequently issued from the agent device before the H / W configuration of the agent device is recognized. in this case,
When the notification information storage memory overflows, the manager device discards the received notification information and advances the recognition process of the H / W configuration of the agent device.

[0010]

Since the conventional manager-agent supervisory control system is constructed as described above, complicated state matching processing may be required when the system is started up, and the manager device is the agent. There is a problem that the startup time until the device can be monitored and controlled is delayed.

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, until the H / W configuration is recognized, the manager device
The notification information is stored. Then, after recognizing the H / W structure, it is identified which agent device the read notification information relates to, and which H / W it corresponds to. The state matching process is performed by specifying whether or not it belongs. Such a complicated state matching process is performed on all the notification information stored in the internal memory. This may delay the startup time of the manager-agent supervisory control system.

Further, when 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 side, since wasteful information to be discarded is sent to the network, a load is imposed on the network. On the other hand, from the manager device side, the state matching process cannot be performed on the discarded notification information. Therefore, contradiction may occur in the time series of information required for state matching.

The present invention has been made to solve the above problems. When a communication connection is established, the agent device stops transmitting notification information to the manager device and stores the notification information as history information. When the manager device recognizes the device configuration of the agent device,
By performing the state matching process with the agent device based on the history information stored so far, the processing load on the manager device side and the complexity of the process at the time of state matching can be reduced, and the manager-agent monitoring control system can be started up. The state adjustment of the manager-agent supervisory control system, the manager device, the agent device, and the manager-agent supervisory control system, which can reduce the load on the network and reduce the network load by suppressing the unnecessary information transmission to the network. The purpose is to obtain a method and a program.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below. Embodiment 1. FIG. 1 is a diagram showing a configuration example of a manager-agent monitoring control system according to Embodiment 1 of the present invention. FIG. 1 (a) shows a system having a single configuration in which a manager device and an agent device are in a one-to-one correspondence, b) is 1
A system in which one manager device monitors and controls a plurality of agent devices, and (c) shows a system in which one manager device monitors and controls a plurality of agent devices, and one agent device is monitored and controlled by a plurality of manager devices. Is shown. In the figure, 1,
Reference numerals 11 to 1N are manager devices that monitor and control the agent devices 2 and 21 to 2N, and are realized by a computer device that executes a program that performs a state matching operation described later. Reference numerals 2, 21 to 2N denote agent devices to be monitored, which are realized by a computer device having means for communicating with the manager devices 1, 11 to 1N and executing 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.

FIG. 2 is a diagram showing a concrete example of the manager-agent monitoring control system in FIG. 1. (a) shows the configuration of the agent devices 1, 11 to 1N, and (b) shows the slot configuration of the agent device. The display screen of the manager apparatus which displays is shown. In the figure, the parts describing DS3, OC3, OC12, and APON indicating the thickness of the communication line connected to the network and the network type indicate the communication board (communication H / W) that uses these communication lines. . Further, in the system in the figure, TMN (Telecommunication) is an interface specification for uniformly managing agent devices of different vendors connected to the Ethernet (R) network.
It shows an example of using the Management Network). Therefore, the agent device 2, 21
2N have an interface function using TMN. In addition, the same components as those in FIG. 1 are designated by the same reference numerals, and duplicate description will be omitted.

Next, the operation will be described. FIG. 3 is a diagram showing a state matching operation by the manager-agent monitoring control system of the first embodiment, and the system configuration of 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 returns a communication establishment completion response to the manager device 11 and, at the same time, suppresses the transmission of the notification information that informs the failure or state change that occurs in itself. More specifically, the agent device 2m identifies the manager device 11 by the communication establishment request received from the manager device 11. Thereby, the agent device 2m determines that the initial state matching with the manager device 11 is not completed, and at the same time as returning the communication establishment completion response, suppresses the transmission of the notification information to the manager device 11. The operation is
This is performed by the notification suppressing means implemented by a program having a function of suppressing the transmission of notification information.

At this time, as shown in FIG. 3, the agent device 2m is already in the communication established state and the manager device 1n (1 <n ≦ N) whose initial state matching is completed.
It does not prevent the sending of notification information to.

The manager devices 11 to 1N do not have the function of holding the H / W configuration information of the agent devices 21 to 2N. Therefore, the manager device 11 does not recognize the H / W configuration information of the agent device 2m. With reference to the example of FIG. 2, the manager device 11
Does not recognize the H / W configuration shown in FIG. 2 (a) and cannot display the slot configuration screen of the agent device 2m as shown in FIG. 2 (b).

Subsequently, the manager device 11 requests the agent device 2m to read out the latest history serial number n. Further, when the agent device 2m receives the above request, it 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) that identifies an event (fault or state change) that has occurred in the agent device 2m. That is, the manager device 11 requests / acquires not only the latest notification information content but the latest history serial number for identifying the same from the agent device 2m. Further, the agent device 2m holds the notification information in association with the history serial number. In this way, the so-called history of the notification information identified by the history serial number is taken in the agent device 2m. The operation is performed by the notification history storage means embodied in a program and a memory having a function of recording the notification information in association with the history serial number.

When the manager device 11 obtains and holds the latest history serial number, the manager device 11 receives information (H / W configuration information) necessary for state matching from the agent device 2m in the period surrounded by the broken line with the symbol A in FIG. Etc.) to generate device configuration information about the agent device 2m. The operation is performed by receiving the H / W configuration information and receiving the agent device 2m.
The device configuration recognition means is realized by a program having a function of recognizing the device configuration. Further, at this time, the agent device 2m has the manager device 11
Regardless of the presence or absence of the notification suppression state for, the history of the notification information related to the occurrence event is kept associated with the history serial number.

Explaining in the example of FIG. 2, the manager device 11 is used as device configuration information regarding the agent device 2m.
Recognizes the slot configuration of the agent device 2m as shown in FIG. Specifically, it can be seen that the H / W for controlling communication such as OC3, OC12, and DS3 is mounted in the slot shown by the diagonal lines in FIG. 2B. However, since the state matching is not completed in this state, the operating state of each H / W is not recognized.

Agent device 2m in the above-mentioned period A
When the recognition of the H / W configuration of the
Is the history serial number (n +) after the latest history serial number n described above.
1) to N are requested to read history information (notification information) to the agent device 2m. The operation is performed by history information acquisition means embodied by a program having a function of requesting and acquiring history information.

As a result, the agent device 2m is
All the history information corresponding to the history serial numbers after the latest history serial number described above is transmitted to the manager device 11 (see the period indicated by reference symbol B in FIG. 3). After that, the agent device 2m releases the notification suppression to the manager device 11.

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. Further, the operation is performed by the state matching means embodied by a program having a function of performing state matching based on history information.

Explaining with an example of FIG. 2, the manager device 1
When the state matching with the agent device 2m is completed, 1 provides a GUI for performing the state display of the H / W mounted in the slot of the agent device 2m as shown in FIG. 2B and the control thereof. Specifically, in the display screen shown in FIG. 2B, the slot in which the faulty H / W is mounted is displayed differently from the slots related to other normal H / W (for example, in the normal one, It is conceivable to add a green color and a red color to the one that has failed).

Next, the case where the agent device requests the manager device to establish communication will be described. Figure 4
FIG. 5 is a diagram showing another example of the state matching operation by the manager-agent monitoring control system of the first embodiment, and the system configuration of 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 2
m suppresses the transmission of the notification information to the manager device 11. Subsequent processing is the same as that described above, so redundant description will be omitted.

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 notifies the manager device 11 of the event that occurred. When the transmission of information is stopped, the notification information is sequentially stored as history information, and the manager device 11 acquires the information for identifying the device configuration from the agent device 2m and recognizes the H / W configuration, the agent device 2m detects the device configuration. Since the history information stored during the recognition of the configuration is sequentially acquired and the history information is reflected in each device configuration to perform the state matching process,
The system startup time can be shortened. In particular, it is effective for shortening the start-up time in the system in which the notification information about the state change from the agent device 2m frequently occurs. Further, since the transmission of the notification information is suppressed, it is possible to suppress the generation of unnecessary information and reduce the network load.

In the above-mentioned first embodiment, FIG.
The system configuration of
It goes without saying that the system configuration shown in (b) can also be applied.

[0035]

As described above, according to the present invention, when the communication connection is established between the manager device and the agent device, the agent device stops transmitting the notification information to the manager device to inform the manager device of the occurred event. At the same time, the notification information is sequentially stored as history information, and when the manager device acquires the information for identifying the device configuration from the agent device and recognizes the device configuration, the history information stored while the device configuration is being recognized from the agent device. Is sequentially acquired and the history information is reflected in each device configuration of the agent device to perform the state matching process, so that there is an effect that 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 related to state changes from the agent device frequently occurs. Further, since the transmission of the notification information is suppressed, it is possible to reduce the load on the network by suppressing the emission of unnecessary information.
