Abstract: A framework for use with object oriented programming systems encapsulates the common attributes of log analysis tools and permits framework implementers to generate customized log analysis tools that share a common structure and organization but are extended only in attributes that are specific to a particular tool. The framework defines a Log object that represents the activity log that is to be analyzed and is responsible for dividing itself into multiple, smaller LogSection objects. Each of the LogSection objects represents a portion of the activity log from which some information can be gathered. The information in a LogSection object is further mapped onto LogEvent objects. Each LogSection object can be referenced by an Analyzer object that controls the analysis.
