Abstract

The present invention determines the type of each piece of system information including a plurality of index values indicative of abnormality levels of a monitoring target device, as follows. The system information and identification information for the system information are sequentially received from the monitoring target device configured to sequentially output the system information together with the identification information for the system information. The piece of the received system information is compared with a predetermined determination criterion and thus determined to be of a particular type based on a result of the comparison. The determined type is output in association with the identification information. Input information indicative of a true type is accepted and stored in association with the identification information. The determination criterion is updated based on the piece of the system information and the information indicative of the true type. In the type determination procedure, an index value irrelevant to the abnormality level of the monitoring target device is included in the piece of the system information for comparison with the determination criterion.

Claims

1. A fault analysis apparatus, comprising:

system information reception means for sequentially receiving system information including a plurality of index values indicative of abnormality levels of a monitoring target device and identification information for the system information, from the monitoring target device configured to sequentially output the system information together with the identification information for the system information;

type determination means for comparing each piece of the system information received by the system information reception means with a predetermined determination criterion to determine the piece of the system information to be of a particular type based on a result of the comparison;

a determination result output section configured to output the identification information for each piece of the system information and the type determined for each piece of the system information, in association with each other;

fault case registration means for accepting input information indicative of a true type of the identification information for the each piece of the system information, the true type identifying a type of a fault of a detected case;

case storage means for storing the identification information for each piece of the system information in association with the true type; and

pattern learning means for updating the determination criterion based on each piece of the system information received by the system information reception means and the true type stored in association with the identification information for each piece of the system information,

wherein the system information reception means comprises temporal status estimated value calculation means for calculating current predicted values for index values included in the system information received by the system information reception means, based on the index values, and

wherein the type determination means includes, in each piece of the system information, the index values including the predicted values calculated by the temporal status estimated value calculating means, and compares resultant system information with the determination criterion to determine each piece of the system information to be of a particular type.

2. A fault analysis apparatus connected to each of a first monitoring target device and a second monitoring target device so as to be capable of communicating with each of the first and second monitoring target devices, the fault analysis apparatus comprising:

system information reception means for sequentially receiving system information including a plurality of index values indicative of abnormality levels of the first and second monitoring target devices and identification information for the system information, from the first and second monitoring target devices;

type determination means for comparing each piece of the system information received by the system information reception means with a predetermined determination criterion to determine each piece of the system information to be of a particular type based on a result of the comparison;

a determination result output section configured to output the identification information for each piece of the system information and the type determined for each piece of the system information, in association with each other;

fault case registration means for accepting input information indicative of a true type of the identification information for each piece of the system information, the true type identifying a type of a fault of a detected case;

case storage means for storing the identification information for each piece of the system information in association with the true type for each of the monitoring target devices; and

pattern learning means for updating the determination criterion based on each piece of the system information received by the system information reception means and the true type stored in association with the identification information for each piece of the system information,

wherein the system information reception means comprises configuration status estimated value calculating means for calculating a relationship between each index value for the first monitoring target device and each index value for the second monitoring target device and determining a predicted value for each index value for the second monitoring target device based on each index value for the first monitoring device and the calculated relationship, and

wherein the type determination means includes the predicted value determined by the configuration status estimated value calculating means, in each piece of the system information, and compares resultant system information with the determination criterion to determine each piece of the system information on the second monitoring target device to be of a particular type.
