Elastic APM Java agent - sanitize_fields_names on application/json* data

[YuZhenXie]

Is it possible to support sanitize_fields_names configuration for application/json* data?Sometimes, requests body contains sensitive data sent to APM when capture_body is enabled.

We hope those fields can be sanitized. We have one way to sanitize them, which is to sanitize/filter out them by ourselves and add them into custom context manually, but we wonder is it possible that Elastic support this function or any suggestion?

Thank you!

Hi @YuZhenXie,

Filtering JSON data at agent level is not supported right now.

However, you can filter data by changing the ingest pipeline used by APM server, which has quite a few advantages:

• support for more than just "field name matching", you have access to all ingest pipeline features
• no performance overhead on the application
