Abstract: A log file including a plurality of log entries is accessed. Each log entry of the plurality of log entries is analyzed to identify components of each log entry. The components of the particular log entry indicate an event. The event is associated with roles. Each role is associated with one or more attributes. Semantic meaning of the event associated with the particular log entry is determined. A mapping is performed by applying contextual information from one or more semantic meaning models stored in a knowledgebase to the identified components of each log entry to derive semantic meaning for the particular log entry. The derived semantic meaning is modeled for the particular log entry. The modeled semantic meaning is recorded in the knowledgebase as a new semantic meaning model for future use.

Abstract: A sample log file including a plurality of log entries for log learning is accessed, using a log interpretation controller, prior to runtime as part of a log learning process. Each of the plurality of log entries is analyzed. A log entry type is assigned to each of the plurality of log entries. A log type and semantic event are assigned to each log entry type. Generation of runtime rules is triggered for analyzing unknown log entries. The runtime rules include characteristics of particular log entry types that allow unique identification of the particular log entry type for a particular unknown log entry. The generated runtime rules are loaded into a runtime parser.
