kandi X-RAY | GrokConstructor Summary
Grok is a collection of named regular expressions that can be used - for instance with logstash - to parse logfiles. GrokDiscovery can somewhat help you by suggesting regular expressions. GrokConstructor goes beyond that by finding many possible regular expressions that match a whole set of logfile lines by using groks patterns and fixed strings. This can be done automatically (which is of limited use only for small stuff), or in a incremental process.
