Abstract

A message control program of an embodiment causes a monitoring apparatus to further function as a plurality of message control unit configured to individually controlling a communication method of a message transmitted from each internal application unit. Each message control unit receives a message containing a message type and service name from the internal application unit. Each message control unit specifies communication method identification information from a file based on the message type and service name in the received message. Each message control unit changes the communication method of the received message based on the specified communication method identification information, and sends the message to a common bus.

2. The message control program according to claim 1, wherein

the communication method identification information contains a communication method name for identifying the communication method, and a unique identifier for identifying one of a connection, a session, and a queue in the communication method, and

the sending unit includes:

a first changing unit configured to change the communication method based on the communication method name;

a second changing unit configured to change one of the connection, the session, and the queue in the communication method based on the unique identifier; and

a unit configured to send the message to the common bus after the changes by the first changing unit and the second changing unit.

3. The message control program according to claim 2, wherein

the communication method identification information contains a first communication method name to be used when there is no delay in transmission of the message, and a second communication method name to be used when there is a delay in transmission of the message, and

the specifying unit specifies one of the first communication method name and the second communication method name from the file based on the message type, the service name, and the presence/absence of a delay.

4. The message control program according to claim 3, wherein

the communication method identification information contains a first communication method name to be used when there is neither a delay nor an error in transmission of the message, and a third communication method name to be used when there is an error in transmission of the message, and

the specifying unit specifies one of the first communication method name and the third communication method name from the file based on the message type, the service name, and the presence/absence of an error.

5. The message control program according to claim 4, wherein

the sending unit changes the communication method, gives the message a change flag indicating the change, a communication method name before the change, and a service name associated with the communication method name before the change, and sends the message to the common bus, and

each message control unit further includes a received message sending unit configured to receive a message sent from another message control unit to the common bus, and to send the message to the internal application unit based on the change flag, the communication method name, and the service name given to the message.

6. The message control program according to claim 1, wherein

the communication method identification information contains a first communication method name to be used when there is no delay in transmission of the message, and a second communication method name to be used when there is a delay in transmission of the message, and

the specifying unit specifies one of the first communication method name and the second communication method name from the file based on the message type, the service name, and the presence/absence of a delay.

7. The message control program according to claim 6, wherein

the communication method identification information contains a first communication method name to be used when there is neither a delay nor an error in transmission of the message, and a third communication method name to be used when there is an error in transmission of the message, and

the specifying unit specifies one of the first communication method name and the third communication method name from the file based on the message type, the service name, and the presence/absence of an error.

8. The message control program according to claim 7, wherein
