The Knowledge Base (KB) is a compiled collection of files, such as event processing rules, class definitions, and executables, organized in a directory structure. The KB files are loaded by a cell at start time. The KB instructs the cell how to format incoming event data, process received events, and display events in a console. Although many KBs can exist within a distributed environment, each cell can be associated with only one KB at a time.The KB is similar to a script, and the cell is the engine that runs the script.
