          To check if your string equals asd * where * is a wildcard, do this:



          if [fieldname] =~ /^asd.*/ 
          # do stuff



          Explanation




          • ^ means that asd should be at the beginning of the line (remove this if it can be anywhere)


          • * matches 0 or more of the preceding token


          • . = any character

          Logstash supports the following comparison operators:



          • equality: ==, !=, <, >, <=, >=

          • regexp: =~, !~ (checks a pattern on the right against a string value on the left)

          • inclusion: in, not in
