Abstract
A system includes a plurality of apparatuses connected to a network, wherein each apparatus monitors the occurrence of trouble in a monitoring object apparatus which is one of the apparatuses in the system. Further, each apparatus is monitored for the occurrence of trouble in the apparatus by a monitor apparatus which is another one of the apparatuses in the system. The system enables adding and subtracting apparatuses to the system, as well as restoring apparatuses which were previously subtracted due to detected troubles which have been corrected.
Claims18
A monitoring system comprising a plurality of apparatuses connected to a network, wherein each apparatus in said plurality of apparatuses exclusively, monitors for an occurrence of trouble in a single monitoring object apparatus, which is one of the other apparatuses of the plurality of apparatuses, and is exclusively monitored by a single monitor apparatus, which is another one of the other apparatuses in the plurality of apparatuses, and wherein each of said plurality of apparatuses comprises:
- a storage apparatus including a management information storing portion in which a monitoring object identifier and a monitor identifier are registered:
- a monitoring unit that monitors for an occurrence of trouble in said monitoring object apparatus indicated by said monitoring object identifier;
- a responding unit that responds to the monitor apparatus indicated by said monitor identifier;
- and a separation processing unit comprising a searching unit that searches, when the monitoring unit detects an occurrence of trouble in the monitor object apparatus, for a search target apparatus, which is the apparatus monitored by the monitor object apparatus in said plurality of apparatuses in said system, said searching unit includes means for searching for said search target apparatus by requesting other apparatuses in said plurality of apparatuses in said system to send back an identifier of the monitor object apparatus of each apparatus of the plurality of apparatuses in the system, and a management information changing unit that makes the search target apparatus as a new monitor object apparatus by changing said monitoring object identifier registered in said storage apparatus to an identifier of said search target apparatus, and changing said monitor identifier registered in storage apparatus of said search target apparatus to an identifier of said apparatus.
An apparatus for use in a system comprising a plurality of said apparatuses connected to a network, wherein each apparatus in said plurality of apparatuses exclusively monitors for an occurrence of trouble in a single monitoring object apparatus, which is one of the other apparatuses of the plurality of apparatuses, and is exclusively monitored by a single monitor apparatus, which is another one of the other apparatuses in the plurality of apparatuses, said comprising:
- a storage apparatus including management information storing portion in which a monitoring object identifier and a monitor identifier are registered;
- a monitoring unit that monitors said monitoring object apparatus indicated by said monitoring object identifier;
- and a responding unit that responds to said monitor apparatus indicated by said monitor identifier;
- and a separation processing unit comprising:
- a searching unit that searches, when the monitoring unit detects an occurrence of trouble in the monitor object apparatus, for a search target apparatus, which is the apparatus monitored by the monitor object apparatus in said plurality of apparatuses in said system, wherein said searching unit includes
- means for searching for said target apparatus by requesting other apparatuses in said plurality of apparatuses in said system to send back an identifier of the monitor object apparatus of each apparatus in said plurality of apparatuses, and
- means for determining said search target apparatus to be responding apparatus which sends back an identifier which indicates the monitoring object apparatus of said apparatus;
- and
- a management information changing unit that makes the search target apparatus as a new monitor object apparatus by changing said monitoring object identifier registered in said apparatus to an identifier of said search target apparatus, and changing said monitor identifier registered in storage apparatus of said search target apparatus to an identifier of said apparatus.
A method performed by an apparatus in a system comprising a plurality of apparatuses connected a network, wherein each apparatus in said plurality of said apparatuses exclusively monitor for an occurrence of trouble in a single monitoring object apparatus, which is one of the other apparatuses of the plurality of apparatuses, and is exclusively monitored by a single monitor apparatus, and with a management information storing portion of a storage apparatus in which a single monitoring object identifier and a single monitor identifier are registered, the method comprising the steps of:
- monitoring a monitoring object apparatus indicated by said single monitoring object identifier;
- and responding to monitoring by a monitor apparatus indicated by said single monitor identifier;
- and
- a separation processing comprising the steps of
- when an occurrence of trouble in the monitor object apparatus is detected, searching for a search target apparatus, which is the apparatus monitored by the monitor object apparatus in said plurality of apparatuses in said system, wherein said searching step comprises the steps of
- searching for said search target apparatus by requesting other apparatuses in said plurality of apparatuses in said system to send back an identifier of the monitor object apparatus in each apparatus of said plurality of apparatuses, and
- determining said search target apparatus to be an apparatus which sends back an identifier which sends back an identifier which indicates the monitoring object apparatus of said apparatus:
- changing said single monitoring object identifier registered in said storage apparatus to an identifier of said search target apparatus;
- and
- changing said monitor identifier registered in storage apparatus of said search target apparatus to an identifier of said apparatus.
A computer readable storage medium tangibly embodying a program code of machine readable instructions executable by an apparatus, in a system comprising a plurality of said apparatuses connected to a network, wherein each apparatus in said plurality of apparatuses exclusively monitors for an occurrence of trouble in a single monitoring object apparatus, which is one of the other apparatuses of the plurality of apparatuses, and is exclusively monitored by a single monitor apparatus, and having a storage apparatus with management information storing portion in which a single monitoring object identifier and a single monitor identifier are registered, the program when executed performing the steps of:
- monitoring a monitoring object apparatus indicated by said single monitoring object identifier;
- and responding to a monitor apparatus indicated by said single monitor identifier;
- responding to a monitor apparatus indicated by said single monitor identifier, and when an occurrence of trouble in the monitor object apparatus is detected, searching for a search target apparatus, which is the apparatus monitored by the monitor object apparatus in said plurality of apparatuses in said system, wherein said searching step includes
- searching for said search target apparatus by requesting other apparatuses in said plurality of apparatuses in said system to send back an identifier of the monitor object apparatus in each apparatus of said plurality of apparatuses, and
- determining said search target apparatus to be an apparatus which sends back an identifier which indicates the monitoring object apparatus of said apparatus
- changing said single monitoring object identifier registered in said storage apparatus to an identifier of said target apparatus;
- and
- changing said monitor identifier registered in storage apparatus of said search target apparatus to an identifier of said apparatus.
