Abstract

A fault information collection program capable of accurately determining redundancy of information related to an identical fault even in cases where information indicating the same fault of the same target of monitoring is received from multiple devices. When new fault information including fault detection date and time is input, the latest fault information indicating a fault related to the fault identical with that of the new fault information is acquired from a message information storage means storing a plurality of past fault information including detection dates and times of faults. It is then determined whether or not a predetermined messaging interval has elapsed since the fault detection date and time indicated by the latest fault information until the fault detection date and time indicated by the new fault information. If the messaging interval has elapsed, the new fault information is stored in the message information storage means as valid fault information.

Claims

1. A fault information collection program for collecting fault information through a redundant network,

wherein the fault information collection program causes a computer to perform a process of:

acquiring, in response to new fault information including detection date and time of a fault, the latest fault information indicative of a fault related to an event identical with that of the new fault information from message information storage means storing a plurality of past fault information including detection dates and times of faults;

determining whether or not a predetermined messaging interval has elapsed since the detection date and time of the fault indicated by the latest fault information until the detection date and time of the fault indicated by the new fault information; and

storing the new fault information in the message information storage means as valid fault information if the predetermined messaging interval has elapsed.

2. The fault information collection program according to claim 1, wherein the new fault information is discarded if the predetermined messaging interval has not elapsed yet.

3. The fault information collection program according to claim 1, wherein the predetermined messaging interval is specified in the latest fault information.

4. The fault information collection program according to claim 1, wherein the predetermined messaging interval is an interval at which a supervisory server for monitoring a target node on the network polls the target node to acquire management information indicating an operating state of the target node.

5. The fault information collection program according to claim 1, wherein fault information stored in the message information storage means and indicating a target node and a fault type identical with those indicated by the new fault information is judged to be the fault information related to the identical fault.

6. A fault information collection apparatus for collecting fault information through a redundant network, comprising:

message information storage means for storing a plurality of past fault information including detection dates and times of faults;

acquisition means for acquiring, in response to new fault information including detection date and time of a fault, the latest fault information indicative of a fault related to a fault identical with that of the new fault information from said message information storage means;

determination means for determining whether or not a predetermined messaging interval has elapsed since the detection date and time of the fault indicated by the latest fault information, acquired by said acquisition means, until the detection date and time of the fault indicated by the new fault information; and

storing means for storing the new fault information in said message information storage means as valid fault information if it is judged by said determination means that the predetermined messaging interval has elapsed.

7. A fault information collection method for collecting fault information through a redundant network by means of a computer, comprising:

acquiring, in response to input of new fault information including detection date and time of a fault input to the computer, the latest fault information indicative of a fault related to a fault identical with that of the new fault information from message information storage means storing a plurality of past fault information including detection dates and times of faults;

determining whether or not a predetermined messaging interval has elapsed since the detection date and time of the fault indicated by the latest fault information until the detection date and time of the fault indicated by the new fault information; and

storing the new fault information in the message information storage means as valid fault information if the predetermined messaging interval has elapsed.

8. A computer-readable recording medium having a fault information collection program recorded thereon for collecting fault information through a redundant network,

wherein the fault information collection program causes the computer to perform a process of:

acquiring, in response to input of new fault information including detection date and time of a fault, the latest fault information indicative of a fault related to a fault identical with that of the new fault information from message information storage means storing a plurality of past fault information including detection dates and times of faults;

determining whether or not a predetermined messaging interval has elapsed since the detection date and time of the fault indicated by the latest fault information until the detection date and time of the fault indicated by the new fault information; and

storing the new fault information in the message information storage means as valid fault information if the predetermined messaging interval has elapsed.
