Filter on tag value in filter

Elastic Stack Logstash
1

Hello,

I know that i can filter on specific tags in Logstash with an IF, but i don't want to filter on the tag names, i want to filter on what a tag contains. So if tag "environment" == "production" then i want to do something.

How can i achieve this? I cannot find it anywhere!

tags do not have values. A tag is just a string in the array which is the tag field. logstash does support conditionals in filters, which allows you to test the values of fields.
