Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a general rule base system.

  In a general rule-based system, a rule is expressed in the form of if. <LHS> .then. <RHS> or when. <LHS> .then. <RHS>. <LHS> is a condition part, and <RHS> is an execution part (LHS is an abbreviation for Left / Hand / Side, and RHS is an abbreviation for Right / Hand / Side). If the condition part of <LHS> is satisfied as a result of collation with the data of the rule base system, the execution part of <RHS> is executed. The rule engine searches the rule base for a rule having <LHS> that matches the data in the working memory, and executes (applies) the rule by executing <RHS> of the matched rule. I will do it.

  In the monitoring system 100, the rule engine 103 executes a rule for data input to the working memory 122. The input means 101 and 102 for inputting data to the working memory 122 are related to the same rule. Since there is no format, even if the contents of data input from the respective input means 101 and 102 are common, if the format is different, different rules must be applied. Therefore, in the monitoring system 100, a system is constructed for each piece of data in which the input means 101 and 102 are different. That is, the monitoring system 100 prepares separate input means 101 and 102 for monitoring the system 1 and the log file 2, respectively, and the rules are the rule 1 for the system 1, the rule 2 for the log file 2, and the data The input means 101 and 102 are prepared separately. As a result, there are many rules that perform similar monitoring processing, and there is a problem that the management of the rules in the rule base 121 becomes complicated.
