Abstract

In a fault information notification system for notifying a manager unit of faults detected by a server unit on a network system in which a plurality of server units and the manager unit which manages the server units are connected in a network, each server unit comprises a fault information producing unit for producing fault information for various faults detected by the server unit to which sequence numbers are assigned, a fault recording unit for recording respective information in an extractable data structure for each fault information, and a fault history search unit for searching corresponding fault history information from the fault recording unit in response to a fault history search request including the reference numbers from the manager unit.

Claims

1. A fault information notification system, comprising:

a network communication path;

a plurality of server units connected to said network communication path;

a manager unit connected to said network communication path and managing said server units, faults detected by said server units being notified to said manager;

wherein each of said server units comprises;

fault information producing means for producing fault information for various faults detected by said server unit to which a sequence number is assigned;

fault recording means for recording the produced fault information in an extractable data structure; and

fault history search means for searching corresponding fault history information from said fault recording means in response to a fault history search request including said sequence number from said manager unit.

2. The fault information notification system according to claim 1, wherein

said fault history search request includes a plurality of sequence numbers, and

said fault history search means searches a plurality of fault history information corresponding to said fault history search request.

3. The fault information notification system according to claim 1, wherein

said fault recording means includes a sequence number indicating latest fault information, and

the latest fault information is notified when said fault history search request from said manager unit does not include said sequence number.

4. A fault information notification system comprising:

a network communication path;

a plurality of server units connected to said network communication path;

a manager unit connected to said network communication path and managing said server units, faults detected by said server units being notified to said manager;

wherein each of said server units comprises;

fault information producing means for producing fault information for various faults detected by said server unit to which a sequence number is assigned;

fault recording means for recording the produced fault information in an extractable data structure;

fault history search means for searching corresponding fault history information from said fault recording means in response to a fault history search request including said sequence number from said, manager unit;

destination registration means for registering said manager unit as a destination of fault notification according to a fault notification request from said manager unit; and

notification means for, in response to production of fault information by said fault information producing means, notifying said manger unit which has been registered in said destination registration means of the produced fault information to which the sequence number has been assigned.

5. The fault information notification system according to claim 4, wherein said destination registration means deletes registration of said registered manager unit according to a notification cancellation request from said manager unit.

6. A fault information notification method for notifying a manager unit of faults detected by a server unit on a network system in which a plurality of server units and the manager unit which manages the server units are connected in a network, wherein each server unit executes the steps of:

producing fault information for various faults detected by said server unit to which a sequence number is assigned;

recording the produced fault information in an extractable data structure; and

searching corresponding fault history information from said recorded information in response to a fault history search request including said sequence number from said manager.

7. A computer program product executable with a computer for fault information notification, said computer program product controlling the computer to execute the steps of:

producing fault information for various faults detected by said computer to which a sequence number is assigned;

recording the produced fault information in an extractable data structure; and

searching corresponding fault history information from said recorded information in response to a fault history search request including said sequence number from a management computer for managing said computer.
