If theCapture multiple valuesoption is checked, each line is scanned separately to match the regex, capturing multiple key/value pairs. This means that it is possible to capture a different key/value set for each matched line. Then, in case of the output log is: ...

If there are duplicate capture names, subroutines refer to the first instance of the given group (matching the behavior of PCRE and Perl). Although subroutines can be chained to any depth, a descriptive error is thrown if they're used recursively. Support for recursion can be added via a pl...
For unnamed capture groups, their index is used as their label. Split input column name: Apply the provided pattern to the name of the input column and use the captures as labels. The impact of this setting depends on the selected Output mode: Columns: The labels will be used as the ...
