Grok is a tool that combines multiple predefined regular expressions to match and split text and map the text segments to keys. Grok can be used to process log data. This topic describes the Grok patterns and provides several examples of basic syntax.
The following table lists the Grok patterns.
Note Named parameters cannot be used in some Grok patterns and their combinations, such as SYSLOGBASE, COMMONAPACHELOG, COMBINEDAPACHELOG, HTTPD20_ERRORLOG, HTTPD24_ERRORLOG, and HTTPD_ERRORLOG.
