Description

The present invention relates to an operating state for an exchange and an operation system composed of a server equipped with a basic function control of an operation system having a redundant configuration of general-purpose server devices, and a client server equipped with a monitoring terminal and equipped with a maintenance terminal function. The present invention relates to a monitoring control system for monitoring

FIG. 7 shows a configuration example of a conventional monitoring control system. In the figure, the center 51 and the maintenance terminal 61 have a server client configuration in the operation system. The center 51 has a configuration in which the servers 52-1 and 52-2 are made redundant, and the maintenance terminal 61 is equipped with a monitoring screen 62.

In the plurality of servers 52-1 and 52-2 constituting the center 51, only one of the monitoring processes 53-1 is activated. When the active monitoring process 53-1 is down or the function of the server 52-1 is stopped due to a failure or the like, the monitoring process 53-2 of the server 52-2 is restarted and monitoring control of the operation system is continued. . However, the alarm / state change information detected by the individual function group processes 54 constituting the operation system is not updated until the monitoring process 53-2 is restarted and the monitoring process 53-2 is restarted. It disappeared without being able to notify the monitoring process 63 (indicated by a broken line in the figure).

In the conventional monitoring and control system, when the operation system is operated, a hardware failure of the server device constituting the center, a software failure, a revision of the operation system, etc. may cause the function to stop, or the center monitoring process may be down due to the failure. . In this case, monitoring of the operation system is interrupted until the monitoring process is restarted, and the information is lost, so the center alarm / status change information could not be notified to the maintenance terminal monitoring process. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a monitoring control system that constantly notifies the system status to the monitoring process of the maintenance terminal without depending on the status of the monitoring process of the center, and enables the operation system to be monitored without interruption. .

The present invention provides a monitoring control system comprising a center with redundant general-purpose server devices and a maintenance terminal for remotely controlling and monitoring an operation system operating on the center. Center / maintenance terminal that establishes a communication path by judging the connection route that can be communicated from the operation status of the monitoring control function of the center's operation system with the maintenance terminal made redundant and the system monitoring means that constantly monitors the operation status of the center And an off-line control means for the maintenance terminal to collect the status of the center and display the status of the operation system on the monitoring screen when the server or the operation system stops functioning.

Here, the system monitoring means may include a monitoring process for realizing the monitoring control function of the operation system in each redundant server constituting the center, and the system status of the server may be exchanged between the monitoring processes of each server. .

The communication path establishment means between the center and the maintenance terminal may be configured to collect information on the operation status of the center monitoring process and select a communication path with the redundant monitoring process according to the status.

The offline control means may be configured to collect the operation status of the server monitoring process from the maintenance terminal monitoring process and display the status of the server and the operation system and the status transition state on the monitoring screen when the operation system is started. Good.

According to the present invention, when a function stop or a failure of a monitoring process occurs due to a server failure, the monitoring processes having a redundant configuration notify each other of the system status by continuous monitoring, and the server and the monitoring process of the maintenance terminal when offline Realize uninterrupted monitoring of operation systems for a wide variety of exchanges, for example, by collecting the status of the operation system and constantly displaying the system status on the monitoring screen of the maintenance terminal without depending on the monitoring process of the center Can do.

  1 to 3 show a configuration example of a monitoring control system of the present invention. FIG. 1 shows a normal state, FIG. 2 shows a failure state, and FIG. 3 shows a recovery state.

 In FIG. 1, the servers 12-1 and 12-2 configured redundantly in the center 11 are activated when the operation system is activated, and a communication path 15 is set between the monitoring processes 13-1 and 13-2. This shortens the time for restarting. The monitoring processes 13-1 and 13-2 of each server are hardware / software alarm / state change information notified from a function group process (hereinafter referred to as "monitoring user process") 14 constituting the operation system of the server. When a certain system status is received, for example, the monitoring process 13-2 distributes the system status to the monitoring process 13-1 via the communication path 15 (S1), and the monitoring process 13-1 communicates with the monitoring process 23 of the maintenance terminal 21. Information notification is performed via the path 16 (S2). Thereby, the monitoring process can always receive the system status of other servers in real time, and can share the latest system status.

 In FIG. 2, when the monitoring process 13-1 stops functioning due to a failure of its own process or a failure of the server 12-1 on which the own process starts, the monitoring started on the server 12-2 instead of the monitoring process 13-1. The process 13-2 continues to monitor the operation system, and notifies the monitoring process 23 of the maintenance terminal 21 of the system status via the communication path 17 (S3). This avoids a lack of system status in the monitoring process 23 of the maintenance terminal 21.

 In FIG. 3, when the monitoring process 13-1 of the server 12-1 that has failed or stopped is restored, the system status of the local server is received from the monitoring user process 14 and notified to the monitoring process 13-2 via the communication path 15. Then, the monitoring process 13-2 notifies the monitoring process 23 of the maintenance terminal 21 of information via the communication path 17 (S5). Thereby, the monitoring of the operation system is continued.

 FIG. 4 shows an example of a communication path switching function between monitoring processes. (1) shows the state of the communication channel at the normal time corresponding to FIG. 1, and (2) shows the state of the communication channel at the time of failure corresponding to FIG.

 In FIG. 4 (1), when normal, communication paths 15 and 16 are connected from the monitoring process 13-2 of the server 12-2 to the monitoring process 23 of the maintenance terminal 21 via the monitoring process 13-1 of the server 12-1. Is set. Here, as shown in FIG. 4 (2), when the server 12-1 or the monitoring process 13-1 fails, the communication path 16 between the down monitoring process 13-1 and the monitoring process 23 of the maintenance terminal 21 is established. Once disconnected. At this time, the distribution control unit 24 of the monitoring process 23 of the maintenance terminal 21 detects disconnection and switches to the communication path 17 with the monitoring process 13-2 running on the other server 12-2. As a result, it is possible to continuously monitor the operation system without interruption time due to switching of the monitoring process.

 FIG. 5 shows an example of offline information management when the functions of all the servers in the center are stopped. In the figure, when the monitoring process 23 of the maintenance terminal 21 determines that the communication path to the servers 12-1 and 12-2 of the center 11 cannot be established (S11), the distribution control unit 24 pings all the servers. Polling by a command is periodically performed (S12), and the center 11 is monitored. The monitoring process 23 displays the establishment failure of the communication path and the result of polling on the monitoring screen 22 as server status information (S13).

 FIG. 6 shows an example of information management after server recovery. In the figure, when the server 12-1 of the center 11 is restored and the ping command is normally completed, the monitoring process 23 of the maintenance terminal 21 accumulates the operating status and failure information of the OS and software in the server 12-1. The operational status progress information (hereinafter referred to as “system log”) 18 is referred to (S21). The monitoring process 23 collects the server status and system status that can be determined from the system log 18, and notifies the monitoring screen 22 of the status (S22).

On the other hand, the monitoring process 23 periodically monitors the activation state of the monitoring process 13-1 of the server 12-1 by the distribution control unit 24 (S23), and establishes a communication path after detecting the activation of the monitoring process 13-1. I do. When the communication path between the monitoring process 23 of the maintenance terminal 21 and the monitoring process 13-1 of the server 12-1 is established, the monitoring process 23 of the maintenance terminal 21 releases the offline state and monitors the server 12-1 in the online state. Waiting to receive information from the process 13-1, the operation system is monitored thereafter.
