Is your feature request related to a problem? Please describe.

The redaction processor currently supports redacting attributes. However, sensitive data often resides in log.body, where user-generated messages or critical information is logged.

I agree that the body is a logical field for this component to comprehend

Hi @karakayasemi , I would like to work on this if possible. As I can see, we want to add something like a blocked_values (similar to the current implementation which masks content in the value of the attributes) for content in log.body. Let me know if this sounds good or do you have something else in mind?

[karakayasemi]

Yes, you can work on this if you are available. We can extend the existing blocked_values logic to log.body for consistency. The current implementation adds redaction.masked.keys and redaction.masked.count as resource attributes and attributes for summary. Similarly, we could introduce redaction.body.masked.keys and redaction.body.masked.count and hold it on attributes to track redactions in log.body. How does that sound?
