Management system, management apparatus and management method
First Claim
1. A management system comprising:
- a plurality of nodes, a node from among the plurality of nodes operating as an application source node, a node to be monitored or a monitoring node, wherein;
the application source node applies for subscription of alive and dead state information to the node to be monitored;
the node to be monitored, upon receiving the applied subscription, makes a connection with the application source node and makes a request to the monitoring node whose routing table includes the node to be monitored for monitoring the node to be monitored and notifying the application source node of a monitoring result;
the monitoring node monitors the node to be monitored upon receiving the request from the node to be monitored and makes a down notification to the application source node upon not receiving a response from the node to be monitored, the down notification notifying that the node to be monitored is down; and
the application source node determines that the node to be monitored stops, upon detecting that the connection is disconnected and receiving the down notification from the monitoring node, and that a problem occurs in a communication line with the node to be monitored upon detecting that the connection is disconnected and not receiving the down notification from the monitoring node.

Abstract
A management system includes an application source node that applies for subscription of alive and dead state information to a node to be monitored, a node to be monitored that interconnects with the application source node and makes a request to a node whose routing table includes the node to be monitored for monitoring the node to be monitored and notifying the application source node of a monitoring result when receiving the subscription application, and a monitoring node that monitors the node to be monitored when receiving the request from the node to be monitored and makes a notification to the application source node when a response from the node to be monitored stops. The application source node determines that the node to be monitored stops when communication with the node to be monitored is disconnected and the notification is received from the monitoring node.

3. A management apparatus operating as an application source node, a node to be monitored or a monitoring node, the managing apparatus comprising a memory and a processor coupled to the memory, the processor being configured to execute a process including:
-
applying for subscription of alive and dead state information to the node to be monitored; making a connection with the application source node, upon receiving the applied subscription from the application source node, and making a request to the monitoring node whose routing table includes a node of the management apparatus for monitoring the node of the management apparatus and notifying the application source node of a monitoring result; monitoring, upon receiving the request from the node to be monitored to monitor the node to be monitored and notify the application source node of the monitoring result, the node to be monitored and making a down notification to the application source node upon not receiving a response from the node to be monitored, the down notification notifying that the node to be monitored is down; and determining that the node to be monitored stops, upon detecting that the connection is disconnected and receiving the down notification from the monitoring node that monitors the node to be monitored, and that a problem occurs in a communication line with the node to be monitored upon detecting that the connection is disconnected and not receiving the down notification from the monitoring node.

4. A management method, used for a management system including a plurality of nodes, a node from among the plurality of nodes operating as an application source node, a node to be monitored or a monitoring node, the management method comprising:
-
applying, by the application source node, for subscription of alive and dead state information to the node to be monitored; making a connection with the application source node, by the node to be monitored, upon receiving the applied subscription, and making a request to the monitoring node whose routing table includes the node to be monitored for monitoring the node to be monitored and notifying the application source node of a monitoring result; monitoring, by the monitoring node, the node to be monitored upon receiving the request from the node to be monitored, and making a down notification to the application source node upon not receiving a response from the node to be monitored, the down notification notifying that the node to be monitored is down; and determining, by the application source node, that the node to be monitored stops, upon detecting that the connection is disconnected and receiving the down notification from the monitoring node, and that a problem occurs in a communication line with the node to be monitored upon detecting that the connection is disconnected and not receiving the down notification from the monitoring node.

5. A non-transitory computer-readable recording medium having stored therein a management program causing a computer to execute a process, the computer operating as an application source node, a node to be monitored or a monitoring node, the process comprising:
-
applying, by the application source node, for subscription of alive and dead state information to the node to be monitored; making a connection with the application source node, by the node to be monitored upon receiving the applied subscription from the application source node, and making a request to the monitoring node whose routing table includes the node to be monitored for monitoring the node to be monitored and notifying the application source node of a monitoring result; upon receiving, by the monitoring node, the request from the node to be monitored to monitor the node to be monitored and notify the application source node of the monitoring result, monitoring the node to be monitored and making a down notification to the application source node upon not receiving a response from the node to be monitored, the down notification notifying that the node to be monitored is down; and determining, by the application source node, that the node to be monitored stops, upon detecting that the connection is disconnected and receiving the down notification from the monitoring node that monitors the node to be monitored, and that a problem occurs in a communication line with the node to be monitored upon detecting that the connection is disconnected and not receiving the down notification from the monitoring node.
