Abstract
A computing device automatically creates a log record recognizer expression and uses the log record recognizer expression to identify a log record type for a log record to parse the log record. A log record type regular expression is selected from log record type regular expressions and is separated into subexpressions that are normalized and are reassembled into an expression recognizer for each log record type regular expression. The expression recognizer for each is read into a data structure. The recognizer expressions are sorted based on an order associated with an expression operator of each subexpression. A log recognizer expression is created from each read expression recognizer included in the sorted recognizer expressions. A log record type of a log record is identified using the created log recognizer expression. A log record type regular expression is selected. The log record is parsed using the selected log record type regular expression.
