You can specify a string to fill the null field values or use the default, field value which is zero ( 0 ). Yes, fieldA means 'fieldA must have a value.' Blank space is actually a valid value, hex 20 ASCII space - but blank fields rarely occur in Splunk. You can replace the null values in one or more fields. The value of this field has the endpoints of the match in terms of zero-offset characters into the matched field. Use the fillnull command to replace null field values with a string. Default: 1 offset_field Syntax: offset_field= Description: If provided, a field is created with the name specified by. display them at left column is search result -only condition is log must. If greater than 1, the resulting fields are multivalued fields. matches regex (2) regex: matches regex: In Splunk, regex is an operator. The syntax of the eval expression is evaluated even before running the actual search and if in case the expression provided is invalid in any scenario, an exception is thrown. Default: _raw max_match Syntax: max_match= Description: Controls the number of times the regular expression is matched. Splunk’s Two Cents On The Usage Of eval Expressions 1. Optional arguments field Syntax: field= Description: The field that you want to extract information from. Sed mode supports the following flags: global (g) and Nth occurrence (N), where N is a number that is the character location in the string. sed-expression Syntax: Description: When mode=sed, specify whether to replace strings (s) or substitute characters (y) in the matching regular expression. mode Syntax: mode=sed Description: Specify to indicate that you are using a sed (UNIX stream editor) expression. See Regular expression syntax for Edge Processor pipelines in Use Edge Processors. In particular RE2 and PCRE accept different syntax for named capture groups.

The Edge Processor solution supports Regular Expression 2 (RE2) syntax instead of PCRE syntax.

d+)' where TOTAL NUMBER OF RECORDS IS:>25.

Regex-expression Syntax: Description: The regular expression using the perl-compatible regular expressions (PCRE) format that defines the information to match and extract from the specified field. I need to Query it in a way that it find a log message if the number of records turn out to be more than 0. Events that do not have a value in the field are not included in the results. You must specify either or mode=sed when you use the rex command. If you search with the expression, every event that has a value in the field, where that value does not match the value you specify, is returned.
