Hello!

I have set up setup in APM server:

setup.template.overwrite: true

setup.template.append\_fields:

- name: http.response.headers

Seems that it doesn't work

@ufanautas welcome to the forum!

Did you make the config change before or after you started ingesting data? Existing indices won't be affected, so you would have to perform a manual rollover on your APM index aliases (`apm-7.15.1-transaction`, `apm-7.15.1-span`, ...). See [Rollover API | Elasticsearch Guide [7.16] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-rollover-index.html) for how to do that.

@axw As I use Docker, I just completely wipe out elastic volume's and built APM image (as i'm copying config inside of it in docker file) Seems nothing to change. only Elasticsearch has persistent volume configured. So a bit confused. Will try this. Will write if it work thanks!

It worked. But APM search bar seems to still use the old ones? The mappings updated, created a new index with it. But it still not searchable

IT worked had to target to create new index with \_rollover/transcation001, but now it seems that the APM server doesn't get anything from its agent.
