Knowledge Base and Rules Compiler

The Performance Manager knowledge base consists of rules and thresholds used to evaluate system performance. The rules, provided at installation time, are known as factory rules. When Performance Manager produces an Analysis Report, by default it uses the factory rules.

Performance Manager also provides the capability to define your own rules. User-defined rules are identified using a text editor to create a file that contains rule definitions. The chapter Customizing the Knowledge Base explains the syntax of user-defined rules. In addition to writing new rules, you can disable any factory rules.

After you define your site-specific rules, you must compile them before Performance Manager can use them. The compiled version of your rules is called an auxiliary knowledge base. After the rules have been compiled, they can be used, along with Performance Manager factory rules, to create an Analysis Report. You can have an auxiliary knowledge base used automatically or can specify it when requesting an Analysis Report.
