Abstract: Automated methods and systems for generating Grok expressions for extraction of metric data from any type of log message are described. Method and systems include construction of a directed graph from Grok patterns. A sample log message is selected from log messages that record metrics values of a desired metric. The directed graph is used to construct a Grok expression from the sample log message. The Grok expression is then used to parse log messages that are of the same type or format as the sample log message to extract the desired metric data from the log messages. The metric may in turn be used to troubleshoot problems anchor identifying potential root causes of problems in a data center or other type of distributed computing system.
