Virtual server ID managing system, integrated monitoring system, virtual server ID managing program, and integrated monitoring program

An integrated monitoring system comprising:

• a monitoring target system including a computer for storing one or more activation-source server disk images and monitoring setting information and a server device for operating a processing for each of a plurality of server instances activated as each of a plurality of virtual servers from each of the one or more activation-source server disk images, wherein;
• a monitoring server device for performing a monitor processing for each of the plurality of virtual servers by using a processing by a monitoring agent, which targets at the monitoring target system;
• and
• a storage device for storing an ID managing program for making the computer execute an information processing of ID management for the monitor processing for each of the plurality of server instances which is each of the plurality of virtual servers,
• in the server device of the monitoring target system, the monitoring agent being operated, the monitoring agent performing a predetermined monitoring processing which targets at the virtual server in accordance with the monitoring setting information for each of the server disk images,
• the monitoring server device performing the monitor processing for the virtual server by using the processing by the monitoring agent,
• the ID managing program includes an ID providing unit, an ID storage unit, and a monitor-data transmitting unit included in the monitoring agent of the server device and a monitor-data receiving unit included in the monitoring server device,
• the ID providing unit performing a processing of providing an ID which is uniquely identifiable to each of the plurality of server instances and a processing of determining whether to newly generate and provide an ID based on a predetermined reference at the activation of the server instance to generate and provide the new ID different from an existing ID if the server instance is newly activated or to provide the same ID as an ID at a previous activation so as to continuously use the ID by using information stored by the ID storage unit if the server instance is restarted,
• the ID storage unit performing a processing of storing information containing the ID provided to each of the server instances into the monitoring setting information for each of the server disk images,
• the monitor-data transmitting unit thereof performing a processing of transmitting monitor data to which information containing the ID provided to the server instance is attached,
• the monitor-data receiving unit performing a processing of retrieving the information containing the ID attached to the received monitor data, and
• the monitoring server device uniquely indentifying all of the plurality of server instances of the monitoring target system by referencing the monitor data and the information containing the ID and performing the monitor processing in accordance with the identification.
