To check if your string equals asd * where * is a wildcard, do this:
if [fieldname] =~ /^asd.*/ {
# do stuff
}
Explanation
^means thatasdshould 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
